So I dont know where my thread keeps going but adding another thread seemed to bring it back last time so here goes. I have this brat. A friend passed and it was left to me. It has a master squirt EFI controller and an 86 gl motor in it.

I am trying to retune the computer because I cant make it start. The latest issue is that the cable I bought to hook up my laptop to the Master Squirt doesnt seem to work with vista 64. Its a DB9 to USB adapter from staples. worst 40 bucks I ever spent. Anybody worked with these things and know where i could look for some advice?

if you mean mega squirt..
usmb forum had a guru for a time.

there is one local to me as well, but also having issues.
