Hi Guys,

i have been searching around for info on which way to go when it comes to upgrading the ECU on a R33 GTS-t manual.

can anyone shed their knowlege when it comes to upgrades as i am sure there are plenty of people asking the same question.

it seems to be the big question between

-NISTUNE

-Apexi Power FC

-Haltech Platinum Pro

-Vipec v44

i know price is a major factor, but is there substacial benifits of each ECU?

thanks in advance

Exactly the same boat that I've been in. Going to ring my tuner and see what their most comfortable with as we all know an ECU is as only good as the tune/tuner. But I'm leaning towards vipec, allows duel fuel maps (E85/98) and also MAF/map tunes.

Do exactly this

Ask your tuner and see what he recommends because an ecu is only as good as the tuner

The other factor is how much you want to remain undercover. Nistune keeps standard ECU and EFM. Looks and works like it's supposed to and could save your bacon when the bacon are perusing through your car. Aftermarket plugins that hide inside a factory ECU case are the next best, but take a lot of extra effort (and a faked up AFM) to camouflage to an equivalent level.

My comment on "ask your tuner" is that a good tuner should be able to handle pretty much any ECU that uses laptop software or a hand controller. It only takes my tuner an extra couple of hours to tune a car for the first time when it's something that he's never seen before (and that happens rarely enough these days) and he wouldn't think of charging the customer for that time. It's his self education investment.

Same guy is so sick of bullshit Haltech failures that he will still tune them, but will not help anyone to install one.

My tuner is so used to tuning power fc's that a complete new tune with different injectors,afm,turbo etc etc.. he got the car running reasonable within 5minutes, and on the dyno took no more than an hour then some small adjustments for half an hour..

in comparison the first tuner i used had it on the dyno for upto 4hours, another tuner asked me for the instruction manual WTF?? so i never used them, lol

Also LINK.

I'd go Nistune on a 8-bit Z32 ECU. I've got one myself. If your tuner doesn't know Nistune I'd be suspicious. However the Z32 into R33 requires more than basic knowledge to work correctly (remove knock sensor, fuel temp resistor, etc).

This has been done to death. In the end you're going to get LOADS of mixed responses because everyone is going to recommend what they have experience with (flying the Link flag myself) and you're not going to be any closer to an answer.

Best way is to just call up your tuner, see if he has a problem tuning any of the ones you are thinking of getting (mine couldn't care less), then do your reading on each one and see which one appeals to you the most. I ended up going with the Link because it ticked all the boxes I wanted and I could get it cheaper than a Vipec even though they are essentially the same thing (some will claim they are exactly the same thing, just different labels).

Yeah I thought of nistune it'd certainly be the most economical on purchase price. But from my understanding (haven't done a tonne of reading yet so don't flame me) you are fairly limited on a Nistune compared to stand alone ECU's?

Limited yes. Limited to what the factory ECU can do - which is run the engine fairly bloody well. But if you want a bunch of aux outputs or tricky rev limits or boost control or dual maps etc etc, then you will need something else.

For a normal street car with a few mods (even up to quite serious mods) it will still be a good choice. Just depends on what your plans are.

    • 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
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
