The warning was just a little blurb under firmware version. Thanks again.

Thank you. Hopefully will make more progress tomorrow.

Thank you. I got a stable idle bumping the fuel table to 55 and the trigger offset still set to -328. Have yet to be able to check base timing because as soon as I open the calibrate window it died. And now that it is up to operating temp, it won't hot restart. But at least I'm at the point where it is tuning related. Another log just to see if there is an obvious area I can tweek to enable me to progress. I was just thinking, it started reliably several times until I tried the base timing operation. Maybe it caused that trigger glitch again? A firmware upgrade resolution? Also, the warning about having a dealer do the firmware upgrade, no dealer anywhere near me. Will I be ok? if I've done, have the experience doing, all the firmware uploads to my Megasquirt? PC Datalog - 2020-11-1 4;27;14 pm.llgx

OK! I changed the trigger offset 360 out and nothing. I changed it back and she fired right up, I Was looking at 1.25 lambda. Got a maximum injector duty cycle reached message, began checking base timing and at -328 offset and a lock at 12 btdc, mark was at tdc. One change to offset to -325 (close to factory setting of -324.5) and it died. Upon trying to restart it wants to start but just won't get there. Do I need to adjust cranking enrichment? More fuel cranking? Also, do I need to subtract 12 from -328 to -340 to get the timing to match? Seems to be way off but if it works I will move on. At least I got fire.

The latest files. Turned on fueling. Smelling fuel at the exhaust tailpipe. No start. BMW E36 M3 TURBO no start2.pclx PC Datalog - 2020-11-1 10;24;53 am.llgx

You were correct, Adam. The strobe didn't work during cranking. I do have spark when looking at the plug. I had to remove and reload PCLink to get trigger scope to work and captured a log. If you could please look over my trigger scope and evaluate. Still, no start. Do you think I should try the base map as Link provided without changes, just to see if it will start? I only changed the tables and fuel mode for forced induction, and also followed the pre-start procedures in the manual instructing to turn some things off. I will turn fueling back on and try again and report back. Also uploaded a screen shot of the capture, I can't tell if the log file saves properly. Thanks TriggerScopeLog.llgx.llgx

This is what I see when I open Trigger Scope. Tried a capture but get nothing. Now what?

Yes, the coils are the same. I have an extension plug wire attached and a timing light on the plug wire. Timing light strobes during ignition test for coil 1, nothing during cranking. I thought I could run a trigger scope but I am humbled. Can you post a procedure, how to? I found the tutorial, the link to one drive didn't work earlier. I'll post it when done.

Thanks. I can do one but I'm sure it is a H/L level sync. Photo of my trigger wheel.

Completing setup on an S50b30us (M50tu). Coils are factory and fire on ignition test. Tried to check timing and get no spark during cranking. Checked connections from crank and cam sensors and they seem fine. Crank sensor seems to be working as I have RPM during cranking. Not sure what else to look for. I have fuel mode set to off to check timing. Please help. Thank you. BMW E36 M3 TURBO no start.pclx no spark cranking.llgx

Thank you for the help. I'll get to know the software, I promise.

Finalizing my install in a 95 M3 US, so basically an M50 harness. Will be a turbocharged platform. I am looking for an aux output for boost control. Looks like Aux 7 is available as I do not have TCM because it is a manual gearbox and Aux-ign 8 as I no longer have the canister or purge valve. I'm having difficulties sorting a connection without hacking up the factory harness. No TP/TCM lead on my harness. Soliciting suggestions. 1. Does it matter which one I use? Is one more suitable for PWM control of a boost valve than the other? 2. Suggestions on the physical connection, tap into the ecu harness plug? If it doesn't matter in the above question, use the purge valve lead since it has a connection to the ECU? 3. If I do not use Aux-ign 8/Purge I do not see an option to turn it off in PCLink. Do I leave it alone? Unassign or reassign to something that allows it to be turned off? 4. Just to confirm, one lead from the boost control valve goes to the Aux output and the other to switched 12v source. Thank you for any help.
