Default Gen 7 Pro's NEED HELP !!!!! PLEASE......

Well the car is kinda starting >

I can crank it and here is pop ?
If i put the gas all the way to the floor it will start and ideal at 500 RPM and the only why to keep it running is to leave my foot to the floor ? As soon as i lift off the car stalls.......

This is the Gen 7 with a dual sync

I have had it ideal at 500 rpm for a bit but when i move the gas it stays the same ?....the throttle is doing nothing ? I have set my low and hi spots...


Any ideas ?

What timing are you running?? It sounds to me like its way retarded. Get a timing light and make sure it is what you think it is.

Other than that if you go under Fuel/Starting there is a thing for putting less starting fuel into the car. I had issues starting my car unless the pedal was most of the way down until I adjusted this. But I would check timing first, because after it starts it should take off to redline right after startup if you keep the pedal down.

The starting stuff is under Fuel/Starting/Starting Fuel Coeficient.

But if the car is running and you are seeing this then you need to change the values in the VE table. Hit the F2 key and it should bring it up. I'm guessing you'll need to be around a 0.300 in your idling spot.

The first time I did my dual sync I was off by 30 degrees. The second time when I fixed it I was off by 10. I've never been able to get it exact the first time so it is VERY IMPORTANT that you check it with a timing light. Good luck.
