Hey, I created a base file for a EJ20 3 cam sensor engine using a V2 map settings that started up and was running fine. Looking for help on what I may have configured incorrectly. I attached both a scope of rising & falling trigger edges selected on the primary trigger. Included are a log, the map and two scope files.

I just had a similar problem with a subaru running in V2 and no start in V3. To my surprise i found my Cranking Fuel TPS 2D was flatlined at -100% by default meaning zero Injector pulse. ---

Not a problem in this case. ---

The rising edge looks good. On the scope I can see spark outputs and fuel injection. Could you please attach your V2 calibration and log from cranking. ---

[nov 17th reviewed.emub](https://community.ecumaster.com/uploads/short-url/amq7qkGxKhvoRixhRaXA8Ewl6Vg.emub) (145.7 KB) At this moment I only have a map that I used before but no log… if that is ultimately necessary, I’ll have to revert to V2 on the cat to get it done. On the rising edge, I believe I was getting one or two pops out the exhaust. But no start. ---

Log from v3 when you crank. ---

A log of cranking on V3 was already posted. It’s above, named “start up”. ---

You are right, I didn’t noticed. ---

Any insight? I thought it was firing order configuration or ignition output/injector phasing ---

Change the primary trigger edge to rising and set invert phase in the firing order options. Should be ok.
