Bought a Superchips thing some years ago on Ebay and thought I would try and fit it.

It was fitted to an MY97 I figured it would bolt straight onto my own MY98 Wagon (Standard).

Anyway, the superchips thing is just a fuel cut defender plus bleed valve. I did a search and found this thread

I read the link to the Pin Out and decided it was pin 6 on Connector B136 (Signal for the MAF sensor). I have duly wired it up, everything looks good - no engine check light etc, but I hit the fuel cut at just over 1 Bar.

I read the link again and it says to use Pin 17 - but according to the PDF that's not connected to anything.

I am really confused.

 

I think I have sussed it.

The Subaru wiring diagram is wrong, pin 17 is correct (for the MAP not MAF as I have connected) but is not marked.

I think this Legacy pinout for the same year shows the solution.
