HI.. after a tune for a cable driven throttle body but suitable for the 1mb LS1 PCM (which normally has the DBW/FBW OS - or at least let me know if you know what car runs this

Thanks

try and make it a little clearer

here it is

VZ commodore runs a LS1 FBW 1M PCM
fuel gauge runs through PCM to dash

want to run LS1 with cable throttle body now
but LS1 512K PCM in Australia does not have fuel gauge running through the PCM

IS there a way or is there an OS in a US car that either Utilises a 1M PCM with cable throttle body or a 512k PCM with fuel gauge setup

thanks for any help :) :)

I have heard that only the '04 1MB PCM has IAC drivers.
OS 12587604 ('04 GTO) uses cable TB.

Good Job... tested today and all works well

is there a 512K OS for a PCM that has the fuel guage go through the PCM and comunicates via serial data to instruments (still cable driven)

The 2002 Camaro/Firebird OS 12212156 is 512KB, has cable throttle, and sends fuel level to IPC via Class 2 serial bus...

cool thanks for that joecar.... wasnt exactly what i was expecting to see in the file.... but will definately give it a go


in the 1MB there are 2 seperate fields that represent guage that this OS doesnt have

but in saying that the guage output field is populated compared to others...

once again thanks for you help and wisdom with overseas OS's .. makes it alot easier for conversions :)

Thinking about it, I'm not sure which IPC's this would work with.
