Trigger wheel setting keeps resetting

Post by nebraska_e28 »

In Megatune 2.25 p3, whenever I set the trigger wheel to 60 under "advanced ignition options" it will reset back to zero if I go back in to look at it. Any thoughts here? Also, while cranking the rpm gauge in MT shows clear up to 3k rpm.

Just checking - you do click Burn to ECU before closing the window, right?

Yes I do click burn. If MS is powered up & I then start TunerStudio it complains that the trigger teeth settings are different. It's like somehow this is being overwritten. When cranking to start it shows around 3000rpm, so I know something aint right.

FIXED. Found 2 errors I made. Tps wasnt hooked up properly & I was set to edis instead of normal coil.

thanks again.
