So, I dealt with a very hard start issue from the get go that my original tuner couldn't nail down. From what I could tell (logging cold starts is really hard) it was getting too much fuel and not enough air. I rescaled the injectors to the ID1300 specs, made inj scalar be 16, cut down the startup inj pulsewidth table (I think to about half of stock), and I set the pedal voltage table spot where it had 0.00 volts to be 1.0, essentially opening the throttle without any pedal input. I did that last step because I got the tune to the point it would fire up with pedal input and then stay running fine. I couldn't find a startup airflow table so I went this route.
After those changes, car fires every single time on cold starts.
If I park the car after a full warm up cycle and coolant temps sitting around 185*, if I immediately or within 5 min or so with coolant still warm, restart it, it will fire with just a touch of hesitation but it does fire.
If I wait say 30min or so, the car will turn over one complete start cycle (about 20 seconds) and shows no sign whatsoever of wanting to start. Just cranks and cranks and then stops. EVERY single time though, I hit the starter again after that crank cycle and immediately fires right up, even better than cold starts.
So I am looking for help on what tables to focus on to help figure this out, its embarrassing to say the least to be at a car show cranking the car like its a 50's gasser.
I have attached the stock tune, the tune the tuner provided that just wouldn't even start, run, or idle, and my current tune that behaves how I described. Sorry no real logs here, the restart after the long crank interrupts the VCM scanner and so the data is always corrupted.
