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.

Its remap time.

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:

    • But it's much better to use a freedom unit that has four different possible meanings...
    • I would try messing with friction modifier to see if it smooths it out.  Just keep adding more until it stops chattering or grabbing quite so much. If you haven't changed the gear oil in a long time you may as well start there too in case that has anything to do with it. You might want to also verify the initial torque is set to the lowest setting too. Requires popping out one of the CV axles first but that's not too bad. Once you're sure the preload is set to the lowest you can try adding an ounce at a time of friction modifier until it feels right to you.
    • It is possibly 55 degrees for the Nismo version. I had a look through the manual and the stocker has a breakaway torque of 2.5 to 3.5kgm. Supposedly the Nismo LSD goes down to 5kgm when worn in but it is pretty grabby even with very little throttle. Worse when cold. So I guess you have three things. 1. Shims. 2 Friction plates 3. Cams Would think shims would be the easiest but Ive no clue how many tenths of a mm shim thickness change equals how many kgm torque. Also not sure if the Nismo friction plates are similar/different to stock or if they are the most of the source of the diff being angry. Think I can write off the Nismo rebuild kit for the standard diff as not being what I want.  
    • Yeah, it was a bit of confusion with me, I rang and asked if they had a boot for a soft top, and then the paint shop when they rang and were asked if it had a hard top on it, which it does, just not a PRHT....LOL Meh, whilst frustrating for all concerned it isn't a war stopper and should be a thing of the past in a week or two In other N/A related news, car is booked in at the end of the month for the cams, springs, retainers, harmonic balancer and retune  I might even pull the lazy arse card and get them to do a full service on it whilst it is there
