Relocating MAF??

[s13konrad05]

Ive relocated my stock sr20det Maf to the throttle body side from its stock location, using extended wiring that was soldered on to the harness,but now I am having problems I crank it over it starts but then dies, the only way to keep it running is to depress the accelerator pedal and keep it above 1600rpms has anyone experienced this before that can help a fellow nissan owner. BTW the MAF is about 6" from the throttle body.Help will be greatly appreciated,THANKS

That's called a blow through system.

Make sure the mafs is before the little hose attatched to the coldpipe.

Ex. Throttle/coupler/coldpipe/hose attatched/than mafs.

The mafs has to have a clear air intake to properly work. Since you have it close to the throttle. That little hose it taking in some air from the mafs.

Hopefully that helps.

the MAFS is also designed to register non-compressed air. The MAFS is probably thinking a small portion of air is coming through than what really is. So when it deligates fuel delivery, it delivers fuel based on calculations for normal air pressure, not for compressed air.

Every turbo system that I see equipped with a MAFS always has the MAFS mounted before the turbo. If you wanted to eliminate the MAFS, then you should consider converting over to a MAPS system.

They are right, the MAFS cannot read compressed air, Ive heard of people with MAFS after the turbo, but never on SRs, another problem will become aparent if you get this set up running, having the MAFS so close to the throttle body will cause deviations in its readings, if you open or close the the throttle body quickly, it will often force air to flow backwards, now normaly the BOV takes car of this, but if your MAFS is so close to your intake its going to read that air, it doesnt know the differance between forward and backward, so air is air, and its going to dump loads of fuel in at odd times causing the car to stumble while trying to do things like throttle lift oversteer, or middrift feathering, it can also happen during quarter mile runs while tring to launch.

You can, and people do, run blow through maf's on SR's.

However it has to be tuned to use a blow through, instead of a suck through. You can't just move the MAF and expect all to be peachy.
