Good Day at Stealth

Just to clear up the maf position questions - On a Vortech the maf needs to be before the charger.

On the ZR1/2 the Maf will go between the charger and the throttle. This is because of the way the z charger draws in air, if you put the maf before it, the maf signals go crazy.

You can rectify this by moveing the Maf further away, but it seems you have to move it atleast 18 inches away from the charger. This isn't usually acheivable, so the only option is to put the maf after the charger.

have the maf after the vortech,runs like a dream?chipstar/AMD piggyback chip mapped by vince 4yrs ago?are obd1 sc set ups fool proof?[the 12/14psi variety].

steve' date=' is your MAF before or after the s/c? I would of thought being before the s/c would be the ideal location!

I found the ideal location for mine is on a shelf in my lockup!!!

I guess when i get my syncro down to vince then a bit more of this mystery will become clear, since the old jakex was obd2 and the new 1 is obd1 and were runnin a very similar charger setup so watch this space for more updates..!

I dont see that there is a mystery, Bosch spent X ammount of years and X ammount of millions of $ to develop an ECU, and it uses a MAF.

Now if it didnt need a MAF to run 100% correct, then bosch wouldnt have made it with one.

I don't think they really planned on half the VR6's that came of the production line being Supercharged either mate!

Exactly, otherwise there wouldn't be a 5V limit for the MAF signal....which that and stalling due to turbulence on the MAF are the only reasons we junk it. Of course we'd like to keep them, but tell that to VFEngineering who developed the kits.
