Well, i just got my first 3rd gen a few days ago, i have since set about de-ricing it and restoring it.

I have already fixed a lot but it has more to do. The biggest issue with it is that the MAP sensor (or the PFC could be the issue), reads wrong. For example, at idle it will read .1 - .3 bar of boost when my boost gauge is showing the real vacume as normal.

Now the other day the map sensor actually worked fine, and the car ran and drove perfect, no issues at all.

But then it went right back to being messed up. Needless to say that it is putting way to much fuel in and flooding it out as it sits.

I realized that with the key off the commander shows the MAP at -~24 and if i turn the key to on it shows boost, instantly changes which has made me wounder if the PFC is to blame.

So i was hoping to try a stock ECU and see what happens. If i could just get this map sensor issue fixed the rest of the car is just time and money to fix.

PM inbound, you might be closer then him.

Oh, and would either of you happen to have a spare stock MAP sensor as well? the issue seems to lie either in the ECU, Map sensor or the wiring to it. Gonna check the wiring today as best i can to rule that out. That just leaves the MAP and ECU.
