Hello Darrel,

How much have you read around here about the required associations between BIN files and XDF files for use with Tuner Pro RT? They must be the same for proper editing of the PCM operating system.

What is the operating system number for your BIN and your XDF?

My fuel pump also starts up and then dies two seconds later . . . . because its supposed to do that - this is the pump "priming time". But it comes back on once I move the key to the start position. Does your fuel pump have power through the fuel pump relay assembly during cranking and after the key is released to the run position?

With your limited knowledge of tuning I would suggest you keep the MAF sensor and upstream O2 sensors. The IAT sensor is incorporated into that style MAF sensor too.
