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:

      New fix for low tyre pressure from bmw

      Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!

      Anyone know this frontpipe?

      Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.

      Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 馃槂

      You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.

      You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
