Car is back in the shop to address the idling issues and a few other things. One thing we are looking at now is the throttle body. I have a Forrester intake manifold that I purchased from Jackson Auto Machine,modified to take a Wilson Throttle Body.
First issue is I purchased a TPS (and only the TPS) from them to go with the throttle body. I asked for a wiring diagram but JAM are being a bunch of idiots about sending me one because they say they have no records of my sale. There is a possibility that the manifold was purchased by Alex on my behalf but it was so long ago I cannot remember. Anyway is there an easy way to ascertain which wires are which and how to wire this in place of the OEM TPS?
Second issue is that whilst I don't feel overly inclined to drop anymore money on JAM after their stunning customer support after spending well over $1000-USD with them, they do actually now sell a machined bracket which bolts directly onto the throttle body into which an IAC unit can be fitted. This looks to be a clean install option. This is the unit itself :-
JAM IAC Housing TPS Kit
I've sent an email to JAM asking about the IAC. But what do you guys think the chances are that the OEM ECU can control an aftermarket IAC?
I'm going down to the shop tomorrow to take another look at the throttle body and OEM TPS IAC setup. I'm wondering if it might be better, easier or even possible to get the Wilson unit machined to accept either the Mitsu TPS/IAC or even both.
