Cranking

Post by Mydmc5898 »

Ok got all the hardware and electrical issues sorted out.
I can't upload my msq from work, has to wait until I get home.
So I have just a have a quick question.
Using Tunerstudio lite.

Since I cleaned up a lot of the issues stated above the car starts nearly everytime.
However sometimes usually mid temps, the car starts but has a low idle, which causes it to die. If I shut it down a few times, maybe 3, it starts fine.

At full warmup if I shut it down I had the cank % set to 100 at 180 degrees.
If I crank it, it sounds like it makes a puff noise and fails to start, second time it starts no problem.
Could I set it lower than 100? Or is that the lowest it should be set?

Again I will upload everything tonight including a data log if it acts up.

Thanks,
Darryl
