[QUOTE="MalcolmV8, post: 15563033, member: 8854"] That's not applicable to our cars. Everything in our ECUs pivots around the MAF sensor. Based on air volume and known air requirements of the engine load can be calculated. Load is then mapped against rpm, throttle position etc. to calculate timing and fueling. No where is MAP sensor readings taken into account with the exception of barometric pressure for elevation changes. Honesty I don't know that the TMAP on our cars is even a real TMAP. If it is providing boost/vacuum no where in the tune is it referenced or used and I've never even seen a PID to data log or view it. [/QUOTE]
