got a question for ya's

i have a type 4 daughter board in my r34.

I know that the daughter board has its own EEPROM that we can change the values in while tuning in nistune software. And the original ECU's EEPROM stays unchanged, we just tell the ECU to read from our new EEPROM. Is this correct?

If this is correct, could i tune my car on pump fuel 98, then take the hex file from the daughter board's EEPROM and burn it into the original ECU's EEPROM, then re-tune the daughter board as usual on e85 fuel? then i just have to run a couple of switch wires from the jumper pins on the original ECU to the dash and i have instant capability to drive on either fuel.

But is it even possible to burn a new image into the original ECU?

and can anyone see any major flaws in my idea?

Nah that wouldn't work, Just have the laptop handy.

Are the daughterboards for 32GTSt and 32GTR the same?

Reason I am asking is I am looking at Nistuning my 32gtst but if I max out my z32 afm, I am wondering if I can swap the daughterboard in to a 32GTR ECU and get a GTR image loaded on there ? (and then run a GTR engine harness and twin afm's)

use a ford lighting maf.

If the resistance is correct they will,If you go low impedance you need resistor.

Yeah they're low impedence and I'm aware of needing resistors but was just flicking through the Nistune website and it mentioned 800cc's being about the limit.. :cool:

What Fuel are you using? Petrol is a bit tough but can be done, E85 with those injectors is easy.

Yeah petrol for now, only looking for 500rwhp but later down the track (after I have put some more pumping power into the fuel system) I was thinking about E85 for track days.

Just wasn't sure whether it was a timing restriction or something that limited you to 800cc..

My setup is:

RB30DET (R32 RB25DE head)

Stock DE cams

GT35R (0.82 exh)

6boob mani

50mm progate

1000cc Rochester inj.

Stock rail and reg (hopefully)

1x 044 in tank

z32 afm (for now, until it maxes)

Will Nistune be able to run this setup nicely? Basically trying to decide whether to sell my Haltech and Nistune it, or keep the Haltech.

It's my track toy so the Haltech has some nice features (rotational idle would be cool) but they're not really needed, could sell it and utilise the money elsewhere..

Cheers for the help!

If I was starting from scratch Id have saved the coin and used Nistune but as you have the Haltech Id keep it. Im using Platinums in most racecars now but the E11s are still very good. 1000cc injectors are good for well over 500rwhp with E85 so its only the delivery that would need updating.

Question.

I have r33 gts.

Mods: r34 cooler, hi flow turbo, splitfire coil pack, exhaust, pod, turbotech T boost controller.

How much would it approximately cost $$$$ to get nistune and approx $$$ to get it tuned in Victoria? Just rough estimate what i need so i know if its worth it.

Im running MINES ecu but if its worth it, might upgrade.

Thanx in advance.

The Haltech came with my Stagea (which will be getting Nistuned soon so VCT and the auto work properly) so I have a bit of flexability there and I guess a couple of extra 044's and a surge tank would be the go when it comes E85 time.

Cheers for the advice! :P

A full tune including installation of the nistune unit would set you back around $800 I imagine, your mods aren't too extreme so they could start with a base map and go from there saving on tuning time. I'm sure you could get it cheaper but with tuning cheaper does not mean better, you are almost always better off spending the extra at a reputable tuner who does nistune ECUs regularly.

I think Dr. Drift in VIC is meant to be one of the better tuners for nistune, though anyone feel free to correct me.

Don't know if you saw Evans, (Quiet achiever on here) DR30 Racecar? Runs 1000cc and 2 044s on E85, makes 620rwhp with more left but the class runs 7inch radials so we could not use the power. 61sec laps on the long track. So 2x 044s will do you fine

Oh very nice :P

Get a decent cooler before an ecu remap, the r34 cooler is not much better than std.

Hi!

I wouldn't say that the R34SMIC is not much better.

It's clearly not as big as a FMIC but depending on your setup it's a good alternative to the standard R33 SMIC.

R34 vs R33

Not everyone wants to run a front mount (police), but thank you for your input, even tho that's not what i was asking...

Why? its junk unless you drive like a 100yo or run std boost. we have tested them over and over for stubborn people who were told online they were a decent upgrade.... they arent. A decent return flow front mount cooler (no cop issues) will allow just about unlimited hard driving before heat soak occurs.... the r34 one needs little more than half a lap or a few spirited runs in the hills before its transformed into a inter warmer.

    • 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
