I was just about to recommend what Stu just did. That guy @ KPT makes all kinds of modules for different functions that you wanted to have stock.
I feel bad for not putting it in yet, but I had no reason to put it in since I hadn't put schmurbos on yet, but he made a module for brake-boosting where it changes a solid brake signal into a single pulse to the ECU so that:
1. The ECU knows the brake signal still works and won't throw a code like it normally would after not seeing an input from the brakes in XX miles
2. The ECU doesn't know you're holding the brake down so it won't limit your RPMs while either trying to launch or trying to brake boost (artificially load turbos to give you positive boost while cruising).
Oh and welcome! Join up on the regional forum (under RiSC, it'll either be MWFX or MWiS, we're voting on that now)
Edit: on the KPT website, it's item # SS20 for the speed-sensitive auto-lock and item # DL20 for the auto-lock and relay pack item # RP20. You must use all 3 together to get the speed-sensitive auto-lock on an Infiniti, and I'm pretty sure it's adjustable to whatever speed you want it to lock at.
Total: $94.97 + S&H
They're from Ohio and these modules are about the size of an iPass or smaller, so shipping shouldn't be much.
