Nismo280zEd Posted May 19, 2009 Share Posted May 19, 2009 Ok, Running 029y4 code on a porsche 911 3.2L motor trying to do a wasted spark with 6 COP and 6 coil drivers. Still having a reset problem as soon as I crank the car, but it's only one reset when I first turn the key. I ran a wire directly from the battery via fuse to MS. So I think it'll be ok. Doesn't seem to be changing settings in MS. Setting wise, using generic wheel setting running a 60-2 wheel sensor is off the 11th tooth using wheel settings I have... trig a 1 return a 9 trig B 21 return B 29 trig C 41 return C 49 used the spreadsheet in the manual and just plug and chugged. MS is in car all readings working it seems. One problem, don't know if I'm getting signal from the VR sensor on the crank. My rpm does no fluctuate while cranking. My car got broken into last thursday so I no longer have my oscilliscope probe to test signal from the senor. It's a three wire VR sensor, one is signal, one is shielded ground and the other is ground I believe. (not 100% on this) Anybody have any ideas on how I can test the signal from the sensor without my scope? I'm also running calculated VE and spark tables based on what MS created for tq and hp numbers. Any help would be appreciated. -Ed I know it's not a Z but it is a 6 cylinder and I could use some help. Porsche guys seem to turn their nose up at MS.

Nismo280zEd Posted May 21, 2009 Author Share Posted May 21, 2009 Update, got confirmation that the sensor is wired correctly, but sense I'm missing my probe unable to check if functioning properly. I'm getting no spark currently. -Ed Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted May 21, 2009 Share Posted May 21, 2009 Do you have a log of the RPM while cranking? Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted May 21, 2009 Author Share Posted May 21, 2009 I did two logs of cranking, show no signal at all for rpm stays 0 the entire time. Checked the jumpers on the board for VR input. I have VRIN-TachSelect and Vroutinv-Tsel So it looks good according to the manual. I tried adjusting the pots back till i heard them click, tried cranking, still no signal, tried turning them while cranking I'm getting nothing. Any ideas or do I need to go buy a new probe.

Matt Cramer Posted May 22, 2009 Share Posted May 22, 2009 Try turning off the wheel decoder and unplugging your injectors - see if you can get RPM that way, just for testing. Quote Link to comment Share on other sites More sharing options...
