I should have gone E-Manage and don't listen to sales bullshit again!!!

All else fails I will sell the Haltech or burn it.

Well the Haltech option is "off" my list of things to do. .

Fcon fz ftw!

but it appears they also use the ksrom like what Scott wants to do.. (i always wondered why they used two computers to run the car properly.)

thanks for clearing that up

What conclusions have you come to Craig?

I have issues with my ecu also as the throttle lag is bloody dangerous. Im hoping to find a spare ecu in japan and ship it to KSrom for a chip. From what ive read they have fixed the lag and im guessing the airflow r&r issue. As they are so cheap, they are possibly the best option if you already have a copgyback,(cant write p*ig? totalitarian website developers!) at least untill someone here cracks the ecu.

There are quite a few companies in Japan that do remaps/custom maps.

Yes KS seem to be the cheapest, but there is also Nismo, TEPS and "G-Zone" that spring to mind immediately although I cannot recall the others at this moment.

They ALL get rid of the 25% throttle <2800rpm among other things.

I should have gone E-Manage and don't listen to sales bullshit again!!!

1. Checked with the dyno guy to see that he had clamped the voltage on the signal from the airflow meter. - Done

2. Checked this is even worth going ahead with by doing a long trip to see wether fuel consumption was better - Done

3. Have tried dropping the boost all the way back to 7PSI.....still has the same problem just with less power. - Done

4. Cleaned airflow meter, throttle body and fliter - Done

5. Need to find someone to make up a bigger airflow meter unit to reduce the voltage and see wether that work....will have to go back on the dyno though.

6. Go down to VIC one day and see wether Cihan can fix.

8. Suggestions ...... I will try anything

All else fails I will sell the Haltech or burn it.

Suggestion #1 - Get a decent tuner for the Haltech. I have heard that JEM and Autotech are pretty good. Do CRD tune Haltech's?

Suggestion #2 - If none of these guys can fix your tune... rip the f**kin' thing out and get either an eManage (road trip down here for tune) or Fcon V and get it tuned in Sydney.

If you decide to go with #2, I would look into the FCON first, although both Cihan (eTuner) and Trent (Status Tuning) are damn good tuners and probably worth the 8hr drive.

Any aftermarket ecu should be able to give you a good tune. The difference between them will be things like ease of use, fineness of adjustment (number of mapping points) computing power, useful life etc. A grunty top shelf ecu will be able to give a super tune - any ecu should be able to provide an adequate tune. If its giving you a crap tune then blame the tuner - in other words find another one. He should be able to make it run properly and tell you if anything is needed to make it run better - e.g. new afm, bigger injectors.

hell, once mine is tuned next friday on the dyno (AEM F/IC-8 & S15 injectors) I'll be toying with the tune myself, laptop

will fit a lambda sensor + guage, and road tune to buggery

=)

You guys know this how? Ive had my car on the dyno for close to 6 hours and only got it partially tuned. The M35 ecu is a lot more complex than you think, and since it controls the throttle, it has ultimate control, even though the Emanage controls injectors and spark.

If its so easy, why hasnt it been done yet?

its because its a copgy-back and they are never as good as a full remap. i THINK with a ksrom,gzone blah blah + emanage or a decent copgy back will be the best IMO.

well, frankly, from ALL research, the AEM F/IC-8 is the best copgyback you can possibly buy, better than the emanage ultimate simply thru the sheer size of the tune scope.

ie 3 different overseeing controls, 22x17 pc mapping x 3, for air:fuel, ign.timing & injector duty.

get a remapped ecu and add in the F/IC-8 or a Emanage Ultimate (same price, emanage is widely known, but the f/ic seems pretty awesome - looks easy enough to self tune with the AEM Wideband kit)

and you'll be laughing !

currently with the remap S1 c34 + safc/sitc got 240rwkw, not a bad tune at all... but with the remap s1 c34 + f/ic-8 copgyback + s15 injectors I expect a much better result.

throw on a wideband kit, save the logs of your drive, and tune to your hearts content :(

Yerrp remap for sure! no need to have all this other copgy back business going on.

if my gtr's motor wasnt near completion i'd buy that m35 tomorrow at pickles. and go thru the process of doing it..

i think i'm about to get buttt raped ;)

Agreed... IF you live in Sydney... and IF you are not modding after the remap!

(unless back and forth interstate trips sound enjoyable)

I wouldnt mind if the price was right. I would still run the emanage for fuel adjustment and multiple maps. Of course I dont think they were looking at the throttle issue were they?

Sounds like the best setup for we "Mexican's"

Don't think is was well known then... but I am sure SAS will be made aware of it.

    • 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.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
