Ok, I got my car running again for the first time in like 5 months, Put a 6an fuel system all the way to the tank, 1200cc secondaries, deleted most of the emmisions stuff. I got it to start on the stock computer and it wouldn't hold idle but I drove it around the block anyway and the add coolant light was on? It also didn't won't to run well at anything at or above 2k rpm. Anyway I have a PowerFC I havn't installed yet, and was wanting to know if that should fix most of those problems, and kinda wanted some advice on how to install, even though it should be fairly simple. I've heard of cutting wires or taking pins out?

 

I don't have a link on this computer, but use the Search button in the engine management PFC subforum and you'll find a diagram for what wires to cut. PFC install is super easy, unplug the harnesses from the stock ecu an plug the into the PFC, minor rigging/cutting needed for the brackets...
