Ok, I bought a car and it came with a lot of receipts but some of them are either bogus ore the previous owner got screwed over by at least one shop.
So I'm trying to get the car to a known condition. It runs pretty good but I'm noticing some stuff is inaccurate. As best I can tell it currently has the following setup.
Sw20 power fc so that should be a Gen 3 setup
Stock harness has been modded to the ecu (might not be exactly correct)
To run properly that would need either a Gen 3 map or apexi map and a Gen 3 ignitor.
I seem to have both the stock gen 2 map and ignitor ( one of the receipts is for an apexi map)
It has an iat sensor on a 2 ft long hose off the back of the plenum that always reads 20 celsius, I have tried a gm iat with the same results.
The car shuts off roughly 1k rpm below where the limiter is set, I believe this is due to the Gen 2 ignitor.
The ecu read out for boost reads higher than my boost gauge, I believe this is because of the Gen 2 map
I have access to a jdm sw20 gen 2 ecu that I would like to run but need to get the harness to a known state to get it right. Does anyone have a diagram that shows wire color at the ecu plugs? Also open to other ideas that don't involve me spending $3-400 on sensors that may or may not solve the issue.
