You need to check the trigger since last home value before moving on. Do you even get an RPM value in ECU Manager while cranking? The VR sensors never go bad. I highly doubt a failed sensor is your issue.

Email me the map your working with. If you have WiFi available where the car is, download the Team Viewer software from teamviewer.com and let me know a good time and I can remote in and try to help you troubleshoot.

i was not watching triggers since last home, but just verifying that the trigger counter increasing while cranking. there was an RPM value in ECU manager while cranking, but it was inconsistent.


what's strange is that we had this set up correctly on sunday: rx8 style trigger settings (vr sensor shimmed to .030), direct fire ignition typical settings, zero'd the timing, got it running nicely, and planned to do a street tune the next evening.
then the next day, poof, no spark except once when turning the key to ON and once or twice while cranking (seemingly randomly). this happened with both the timing light and an additional NEW spark plug attached to one of the coils while cranking.
last night we re-shimmed the trigger from .030 to .020 and then to .040 just for troubleshooting, and it seemed to make no difference. i also changed the trigger voltage up and down slightly and their original settings (which were being used sunday) seem to work best.

things we did not do last night:
1. replace all 4 spark plugs with new spark plugs
2. watch triggers since last home

if the spark plugs don't fix it i'm stumped. the teamviewer idea is probably best at this point, ludwig, if you can do that at some point this evening.
