Well, had a couple hours and that was all with company over and I tried to fire up my 03 GT with a fresh installed ms3pnp. The small red leds were on but none of the larger 4 LEDS would light, and my laptop would not recognize the device (possibly a com port issue, looking at that). I have 60# injex and it turned over and I feel like I heard a few attempts to start of course the base tune had stock injex and I adjusted in TS but couldnt write to device as it wouldnt recognize it. Tech support is out until the 28th. What are those other LEDs besides the small red ones? I couldnt figure out by the manual. Going to try again with laptop and want to see if there is spark with a spark tester. Without being able to calibrate tps and with the wrong injex, I imagine it would have a hard time firing up. I had about 8 cranks worth before battery was low and I had to go back to life stuff. If it has spark at all, that means this thing is working (right?), if it has anything on the plugs as far as fuel, its working. I just havent been able to test spark or fuel. Ive never had a standalone install go bad.
