here is the idle log with the newest tune . notthe greatest and im having issues with the throttle body.
has anyone worked with torque rush d2a module because its been giving me issues and the truck goes into reduced power mode unless i turn off the codes
What MAP sensor is installed?
The log shows it pegged at 105kpa with the key on engine off. That tells me the data is wrong for the that sensor.
No idea on the throttle body module stuff. Sounds like a giant can of worms.
yah my buddy insisted on dbw and it has been giving me nothing but problems . also we are using a 3 bar sensor same pn as the sc output map from an lsa
ACDelco 12592525
The LSA map sensor data is 312.50 and -11.25. You'll need to correct for that.
I mean drive by wire is fine but you could make all the power that stock engine can make on the stock 78mm throttle body. Going to the 102mm is purely for looks and or flushing money away.
we are running a twin turbo setup i told him we coulda got away with a 92mm and it woulda made tuning a touch easier but the new motor will be a 408 stroker so it was just a spend money once kinda thing.
those are the numbers going in for MAP linear and offset yah ?
Yes.
i know these are fairly noobish questions . But i am trying to start learning so the only stupid question in my eyes is the one not asked lol
here is the log after the MAP changes
