So i am having problems with getting the car to brap. The engine is brand new and i cannot get the Brap to happen lower than 1800rpm. I can get a rock steady idle at 1300 but it sounds like a machine gun. Using the Idle control Valve

I have attached the map, any suggestion would be greatly appreciated.

What AFR does it run at a 1300 rpm idle?

I'm fairly certain that more timing + richer idle is the key to a brappy bridgeport idle, but I don't know for certain as I've never tuned one.

I can throw 20 degrees of timing at it with a afr of 12.2 and still just doesn't brap, tried the combination of split timing as well. It's happy brapping at 1800 with an afr of 13.2 and 9.2 degrees of advance.

I have not done a lot of half bridge engines, but they seem to like the higher idle for the very pronounced mis( the brap).
