I have the MS installation hooked up and taking to MegaTune on my Porsche 914. During the prestart testing the sensors checked out with reasonable values except the TPS & MAT sensors. I have the Barometric option OFF.
The MAT was reading 169, but it was a chilli 55deg here in Phoenix this morning. The TPS was showing a high value 245 for the closed position, and 80 for the WOT position. I have the TPS rotating CW - resistance increasing with CW rotation. Any thoughts? TIA, |

Make sure you include the corresponding .inc files in your Megatune directory otherwise it will use the default files that correspond to the GM sensors that Bruce used. You will set the TPS values in Megatune so don't worry too much about that. If all of the above is right then recheck the wiring Dave |
