Hello, as the title says at random times after the vehicle has been driven hard for a few sessions at the track, vehicle has trouble starting, issue happened once i parked it to wait til next session. I also noticed issue happens after i spun out twice, vehicle took a few minutes before it was able to start. is this a common issue with aem ems v2 w/ bolts (intake/header/exhaust/tb). Normally I have the typical longer delay start up with the aem, which im okay with because I was able to get it as close as oem start up as possible but mainly curious if there's other people with same issue. Hopefully I gave you guys enough info on my issue.

No, it should start like stock. My car is a F24 on E85, with head work and a rowdy ass cam. Starts like stock. You probably just need your cranking and afterstart fuel tables adjusted. Contact AP1chief here on the forum. Im sure he can straighten it out for you.

Make sure your valve lash is in spec first though.

I've always noticed that my old AEM V2 just took a couple more seconds of cranking to start. I've also noticed that when I spun out at the track (which I don't do much anymore), it would take a minute or so to be able to start up again. I assumed a fuel issue. Not with a lazy slow spin, but only with a pucker factor spin.
