AEM EFI starting & tuning (Gen3 426)

What injector size? You can copy one of my tunes from the Megasquirt thread that is a sticky in this sub forum. That'll get you moving in the right direction. You'll need to input your engine size and injector size into the tuning program for the VE tables to calculate correctly, though. Ask questions if that doesn't make sense.

I'm pretty sure I have the SRT4 stage 1 injectors (577cc/min, 55lb @ 58psi). I understand what you're saying about scaling the VE tables for my specific parameters. I'll take a look at the Megasquirt thread, thanks man.

Cuda SRT8, you are just the type of contributor I was hoping would chime in! Is your motor running? Have you tuned it? I've hodgepodged my setup together and acquired the ECU/harness as "throw ins" (!!) when I picked up my intake manifold, fuel rails/injectors, and cable operated TB from a guy on the STR8 Jeep forum, and didn't come with the CD, to which the instructions referred. That's been a missing link and I would LOVE to get a copy of that. When I first got the ECU I powered it up and was able to pull & push tunes to it and I'm somewhat familiar with the AEM software interface. I've also talked to Henry at AEM who gave me a base tune for it (a 392 oddly enough ;-) which I'll scale up. First, I need to at last know it can light the motor: spark & fuel. I live in Humboldt about 5hrs from you but have very good friends in the eastbay area. We definitely need to get together, I'll be in touch...

I'll contribute back to this thread when I gather more info and have resolved my issue. Stay tuned!
