The one big thing I see is there doesn't appear to be enough tunability. It appears to be a FI setup for naturally aspirated use based on only having 2 pots to do tuning. Unless the system is specifically set up for boosted operation, the computer won't know what to do. The MAP (I'm assuming it's a speed density setup) on it probably won't read postive manifold pressure and even if you changed the MAP, it would still be lost. I'm assuming a lot though and we all know what this does sometimes.....Clay

I know on Megasquirt that was a parameter you could set. It was something like a prime at key on duration you could set. I guess it was replicating a small pump shot like you would get on a carburetor. What you're seeing may be normal, but unfortunately that's about all I know. Clay

That's pretty close to the same system I'm running in my boat. You should be able to connect into the ECM via Calmap 6.2 which runs in DOS. If this is the same controller I would stay away from it. Table resolution is small and logging is terrible. If you stay with the power commander you'll have even less tunability.

If this is the system I think it is then it's very old and hard to tune. Therefore I wouldn't recommend it.

yea basically the same thing i heard from my machinest. what he told me is it would work great in a truck or street car because of the bottom end torque, but he wouldnt put it in a drag car. alright thanks for the help.
