So I've been asked to do a writeup on how to make the Z32 MAF setup work with the JWT ECU + 370cc Injectors while S/C'ed on the charged side.
Symptoms:
With the Z32 MAF on the charged side and stock Stillen piping the car idles horribly, bucks hard when cold, and is generally undrivable.
Solution:
The Stock Stillen piping doesn't work well with this setup. After spending a year trying to figure out if it was compressor surge, vacuum leak, etc, etc it turned out the reason (And solution) is quite simple.
I needed 3" Piping.
The reason is not compressor surge or any performance boost with 3" piping. The reason is simply that with the flange on the stock Stillen piping facing the way it faces, it causes the MAF harness to face up or down.
It must face towards the battery - like this:
As soon as I had the 3" piping in originally (With the harness facing up) - it still idled and ran horribly especially when cold.
Turned the MAf 90 degrees - and problem solved.
Car idles a little wonky for 90 seconds on cold days - and has some dead spots at low RPM when cold - but it is drivable. As soon as it warms up even a little - it idles BETTER than it did with the A32 MAF and runs perfectly.
Sticky this bish!
car idles fine. But in any case cant wait to go to 3 inch piping.
