[In Development] VT - VY Ecotec / L67 Spark Cut Rev Limiter

[JCSuperina]

Well if you ever want someone else to test it on their skid pit let me know happy to be a tester for ya

If you set the limiter to 6375 on factory code it will skip the limiter all together, this is because the code checks if the rpm > what you set, and 6375 is 0xFF in the calibration so it's max and can't get any bigger, so if it's not above the limit it will skip the limiter, you can patch the ECU to read the RPM from a 16 bit address instead and read up to 8000+ RPM however at 6500+ RPM the spark control becomes less then average.

The way this works is factory code has RPM as an 8 bit value that uses 25 RPM per bit, so the max a 8 bit value can be is 255 which is 0xFF in hex and 255 x 25 = 6375.

So yes it can be done but in my opinion there's no point until you sort out the spark control issue, that and the ecu would require more patches to extend the tables to be able to "tune" at that RPM.

thats awesome work!!

i feel like i know you from GTA days but cant quite remember if it was ChromeXmods or something like that

Ahahaha yeah Chr0m3 x MoDz was me in the GTA days!

bro no way i didnt know you were aussie haha i miss the old gen days thats for sure and now ive moved over to doing cars and tuning like you have i guess thats crazy me and a few mates used to sell heaps of modded consoles back in the day used to make good cash off it
