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:

      From Japan and back to Europe, my sh*tbox R34 GTT

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
