Rafe:
I believe you are correct. Mine is one of the early 96's (bought in 3/96). It has gotten that emmisions recall with all the inspections and free ignition parts, although I haven't gone in for it and might not.
My bet is that this matters not. We'll see soon enough.

This mod won't matter much on a turbo because you don't get as much part thottle boost. That's the root of the supercharger detonation problems.

Holden,
Whats your gas mileage look like after this mod???

I'll let you know. I never even got in a full tank with the BTC! It might take me 2 weeks to go through a tank.
I used to get 26mpg very steadily before the BTC and the TPS relay.

Just installed the TPS trick this evening.. It works like a champ. Everything works as expected (looking at the a/f gauge). Since I never had detonation to begin with so I can't really tell with the mod. I'm sure it helps eliminate those inaudible ones. Throttle seems to be a little more responsive..but it may be my imagination http://www.hostboard.com/ubb/smile.gif
Just for full disclosure here:
My idle now takes 20 seconds to calm down. It slowly bobs from 1000rpm to 1200rpm for that time period, then calms down to a steady 700rpm.
Most likely this is due to a small vacuum leak I created while installing the TPS wiring or because of the new, cold temperatures here (30's all weekend). Does the ECU "learn" seasons?
But it could be some type of side affect to the TPS trick. I doubt it though.
I'll keep you posted when I fix this.
Greg
I haven't noticed this at all, or any other ill effects for that matter. How did you create a vaccuum leak?
I don't know. I'm just guessing. But right in the same area where I was muscling the TPS and MAP harnesses are plenty of suspects.
In order to splice into the TPS harness, I pulled it (and the MAP harness) around to the front side of the intake piping for more slack. (Then shoved it back for re-install). A vacuum line/connection may have been bumped during this.
Greg
No funny idle here. Idle is rock steady at 750 - 800 rpm... when installing the TPS trick relay, I removed the intake pipe (short ram) and everything was accessible.
Mine does this too... just when u start the car cold... idles from 1700 to 2000... and bobs back and forth.... in my case it was caused and is still caused by a vacum leak... i run a bleeder to control boost... and off the exhaust ports of the bleeder i havnt put back the check valves after i was playing around with the setup...
MDA:
I had a problem like that once right after my install, but fixed the leak pronto because it was throwing IAC codes.
My current situation only happens when the car is fully warm (water temp gauge at just under 1/2). Even then, it only happens when say you're driving and come up to a stoplight. Then, rpms go back and forth slowly between 1000 and 1200 a few times before settling down to a steady 700.
I'm going to drive on it for a while because I think it may just be the cold. Anyone else have 30F degree temps right now? 1/2" of snow yesterday. WooHooo!!!
