I just thought about this while reading Rotorman88's post on his intercooler, and was wondering if the S5 MAF is better than the S4 and if it would swap. The S5 MAF looks a little better than the S4. I just think the S4 MAF is kind of restrictive looking. Anybody ever try to swap them? Or maybe know an inexpensive way to go without one. I know a company a while ago made a Vein Pressure Controller to convert from Mass Air Flow to Speed Density(MAP) but haven't been able to find it. Anybody know anything about this?



Thanks in advance. https://www.nopistons.com/forums/pub...IR#>/smile.png

The s5 is better flow then the previous s4, and I know you can swap them, but it isnt plug and play..I can't remember details right now, but I'm sure somebody will shed some light.........

Coo!

I wish I had known this a long time ago. I could have saved some of my friends a lot of money.

Okay, so let's make this perfectly clear:



Is the diagram:

A) BULLSHIT

B) NOT BULLSHIT

The diagram is correct. I used it for my 88gxl when i swapped out the afm for a s5. MAKE SURE YOU MARK THE E1 GROUND CAUSE YOUR RIDE WONT RUN IF YOU DID THE WIRING WRONG IT'LL START AND STALL!!
