I recently installed a megasquirt pnp2 from DIY auto tune on my 94 1.8 Miata. I got it all installed and set up for first start.

I also noticed that after I turned the key off and back on the check engine light flashed twice for about 5

 

Sorry for the double post. The one above is finished.

 

That is a bit odd. Can you try getting a data log of what's going on?

 

I wont be able to work on the car again until next weekend. But if I can't get it running then ill post a datalog. I was just wondering if I could maybe get some insight before I'm able to dive back in to it.

 

Hey matt, I tried working on the car today when I plugged in my computer and clicked create new project, then detect for the firmware and it just searched for about 10 minutes before I cancelled. I'm at a loss here, not computer savvy at all. Do you know what would cause this.

 

I re-installed tuner studio, connected to ecu and the car started right up.
