Yes I have one of those and it works very well . I got the Haltech people in Taren Point (Syd) to test mine along side a Uego probe of theirs some years ago (on their static 1GGEU test engine) and the readings were virtually identical .

I used it for years on an Autroniced FJ20ET powered Bluebird with great results . The Haltuner is not the tool to tune engines on the bleeding edge , but it has more than enough scope to tell you if the mixtures are reasonable or getting out of hand . Its a fantastic thing to have permanently installed to give you an idea whats happening ALL the time . If I was made of money I would have the Autronic air fuel ratio meter with the Bosch 4 wire probe , people trust them and they give a numeric rather than LED read out .

For the cost the Haltuner is probably hard to beat .

Yeah well the cost of mine was pretty good, cost me nothin :headspin:

I also got the O2 senor to go with it but doesnt look like your normal o2 senors, it hard to eplain what it looks like so ill take a photo and post it up. Im thinking it might be a 4 wire probe like your talking about???

So you think it would be a good idea to install it to keep an eye on things when engine goes back in after rebuild?

Thank guys ;)

Well i looked at these the other day briefly.

As soon as i seen the price, something like $300 odd, i knew it had to be narrow band based.

And further research on the net basically confirmed this by owners of this tool.

Lastly i found this on the ECU manual from Haltech relating to their haltech haltuner

The Haltuner is an inexpensive air/fuel ratio indicator that gives a full-scale deflection from rich to lean over a display of 30 bar segments. It is compatible with all Oxygen Sensors that output a 0-1V and can be configured upon request for other sensor ranges.

Since when did widebands come with a 0-1V output.

Sure they thing can read a 0-5V wideband, but you have to get Haltech to reprogram the bloody thing.

Basically you wouldn't want to use it for any sort of forced induction tuning, unless you know it is setup for wideband sensors. Then you have the heater elements inside widebands that have to be accurately controlled for accurate readings. I somehow think the $300 Haltuner lacks some of this logic.

I don't want to get involved in an argument here but I know what I saw with my own eyes . The NTC probe I have I bought with the E6 computer in about 90 - 91 . Much later I bought the Haltuner which if memory serves me correct was around $235 trade - not including the probe which I already had . The NTC probe is heated and I think four wire . As I mentioned I got it tested in tandem with EFI Technology's own Uego equipment because I suspected my probe was poisoned .

If you can find him Justin is the man to ask , I believe he left EFI Technology some years back to start his own aftermarket EFI fitting and tuning business .

Anyhow I tuned that FJ20ET with 550 cc injectors to give 27-28 mpg , good hot and cold starting and smooth transitions - good manners and no closed loop correction . I put a lot of that down to the Autronic SMC's fine resolution and charge temperature management , but it didn't tune itself (pre autotune) and the Haltuner was the only AFR measurement device used .

Having said this I do not suggest people should tune their own cars on the street , I had a bad experience with a chassis dyno operator who cooked my no 4 piston and was using Autronic/Bosch 4 Wire equipment - cost me 5 G's . After that I did my own using MK1 eyes and ears and a Haltuner . The car was daily driven and it was in my best interest to get good fuel consumption . I also switched to a button (padle) clutch and as everyone who uses them knows engine response and part throttle torque needs to be the best it can particularly with lowish 8.5 CR . As I said before it worked well for me so was good value .

My opinion only , cheers A .

My 20 cents.....

The LM1 wide band A/F ratio meter is a better buy for not much more cost. Noting that the cost of wide and fast lambda sensors has dropped considerably as there use becomes more common. Ditto the cost of meters for utilising the lamda sensors.

Like discopotato03, I have tuned a car using a narrow band lambda sensor for maximum fuel economy, idle and off idle stability. The A/F ratio I was aiming for (for best economy) was in the range that the "narrow" lambda sensor covered with some accuracy (around stoich). Also the lambda sensor was "slow", meaning that its reponses to changes in A/F ratios was not instantaneous, it took a little while to record the movement. This is obviously not a problem when tuning for economy.

But (there is always a but), when tuning for power and response, I don't want stoich A/F ratios and the changes are rapid, so I can't use a narrow and slow lambda sensor.:rofl:

The LM1 , I'll do a search on that one . Agree with the high cost of good equipment in the early and mid 90's . My reason for parting with the Haltech and Autronic computers was I wanted something that could load sense via a mass air sensor rather than MAP . I feel there's to many air temp correction advantages to pass up and it seems logical to match air to fuel ratios by mass . I'd like my next car to have some form of AFR meter so I'll see whats around then .

Cheers A .

Hey guys you have missed my point to his thread :) All I wanted to know would it be worth while intalling the haltuner to keep a check on a/f? I have no intention on tuning the car with it and it would be a shitload better than some a/f ratio guage from autometer or something shorly :)

These don't look to bad at all.

Im thinking of getting one shortly just to see what they are like.

Unless its accurate, I don't really see how you can keep an eye on anything, I mean a cheap narrow band will show if its gone way lean, or way rich, but chances are what really will happen is the AFR may drop from say 12.0:1 to 13.5:1. And this could be a big concern on a forced induction car. I just don't trust a narrow band to show me that small change instantly.

At the end of the day, if your car is tuned properly, and you don't tinker with it just keep an ear out for detonation.

If you want real accuracy get a wideband.

If you want something a little better then the standard narrow band get the Haltuner and included O2 sensor.

discopotato03, said he used one with great sucess, get one and give it a go. He has had real experience with it. Im just going of the specs and what i have read from users of the tool on other forums.

Let us know how it performs.

I hope we can keep adding to this discussion.

Cheers!

My answer would be yes but they have a new version soon to be released . They are getting a 5 wire Uego probe which will read between 10 and 20:1 AFR and could sell for around $300 (current estimate) . This is good news to me because the LED display should work with it once the narrow band eproms are exchanged for the wide band ones . EFI technology say the sticker on the front of the display is changed for one with numbers ie 10 11 etc up to 20:1 . Does anyone have any details or experience with the Uego 5 wire wide band oxygen sensor ?

Cheers A .

We use the Bosch LSU4.2 5-wire, wide-band O2 sensor. Cost is $US80 plus freight (no import duty, good on you Johnny, Feee Trade Agreement). Works perfectly with the Motec, Autronic and LM1 A/F ratio meters.:(

Thanks SK , did a search on the LM1 and found lots of information on the 6066 Bosch probe and some on the NTK version . I'll contact EFI Technology and see which one they're going to use .

Was yours imported from the land of George Dubya or are they available here ?

Thanks A .

whats the LM1 A/F Ratio Meter worth and where can you buy them as have been looking for a good a/f ratio meter for tuner for some time

has anyone run one of these ? if so how do they rate

Just off the tellingbone , EFI Technology will be using the Bosch LSU Version 4.2 wide band 5 wire oxygen sensor which they say should cost $140 by itself . Their next Haltuner version kit with the above probe should retail for $300-350 complete . I don't know if it will have a memory function or logging facility but may suit some for monitoring or diagnostics .

I haven't used one that had a numeric display , only the LED type but I suppose its the accuracy thats important . I gather most professional level equipment is numeric from what Ive seen .

I got mine from the US direct, we have a race team that we supply in Florida and they get stuff for us. Cost around $US370, plus $A30 freight. Innovate Motorsport have an Australian agent, it's on their website.:)

    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
