Ecu Programming Question

Hey people,

Does anybody know whether it is possible to alter the rev limiter value of a stock ECU while it is in the car?

I have replaced the stock chip in my car (R32 GTS-t) with a different chip, and the new tune either has no rev limiter or it's higher than 8000rpm (i don't want to find out past there!)...

So, can I use my consult cable and some nifty software to change the value? Or is it required that I take the chip out and have someone re-map it?

If it's the second one, I can't be stuffed and will stick with the Bee*r limiter.

Thanks in advance for any replies!!

Bobby.

it depends on what sort of chip it is running. if it is something like the nistune daughterboard then it can be done with just the nistune software and a laptop without touching the rest of the tune. if it is a rom chip that has to be burnt each time something is altered then it will need to be done by someone who can do that sort of thing.

Thanks for the replies. I can do that sort of thing. I've done a lot of google-ing (I guess I should have first) and have the info I need... but it seems it's going to have to be a remap as you guys suggest.

Can I be frigged doing a remap just for rev limiter? Probably not but I've just had the stupid bee*r blow my O2 sensor so maybe I should before the damn thing does something major. That'll teach me for hitting it to stop tailgaters :laugh:

      Rb25 trigger kit and timing misalignment

      The trigger kit I have is similar to the one in the link below. While going through Facebook, I saw someone else mention a similar issue, and I’m starting to think this could be related to the crank gear itself. I understand these parts are CNC machined, but maybe some earlier versions or individual pieces might have slight inconsistencies—it just doesn’t look right in my case. https://www.facebook.com/share/16an8evZd9/?mibextid=wwXIfr I originally installed the crank gear using the thin OEM washer, but as shown in the attached photo, the timing belt walks very close to the edge. When I tried using a Nitto washer—which is thicker—it actually made the issue worse. The belt walks about 1mm off the front edge, which raises more concern about alignment.   I’ve gone through the full process of elimination:   The tensioner pulley and bolt are brand new and installed correctly. The bolt isn’t bent and is oriented properly. The back of the tensioner and the idler pulley are clean and seated correctly. The idler sits slightly more forward, which I understand is due to its design. I’ve experimented with both tight and loose belt tension, but it makes no difference. As soon as the engine runs, the belt immediately walks forward again—even if I reset it beforehand.     At this point, I’m considering replacing the crank gear with your Race Version 1 (12-tooth), but before purchasing, I wanted to ask:   Are you aware of any alignment issues when using this gear? Would this gear help keep the belt aligned correctly, or could the walking still occur? Does it work with a standard missing-tooth crank and rear washer? Is there any specific crank setup or install procedure required?     For reference, I’m not using a front washer, as the PRP crank gear seems to replace the need for one.   Looking forward to your advice.

      Yep, looks that way. Never driven an E30 or R31 so I can only imagine

      Yuh, My new R34 box is sitting on the workshop floor (in its large shipping box, which is a nice thing on its own), along with a front plate to convert to push clutch. There was no way I was interested in rebuilding my existing one. Was only partly interested in the risk of buying a used one. But, if you want a 2nd hander, I can point you to one in/near Melbourne at least. @Komdotkom has one that should be in good enough condition to be usable. I don't think it's in a for sale thread, you'd have to message him. @redzedhas one that definitely needs a rebuild.
