I had an idea how to allow people to get a BOV and fix the issue of running too rich. If you had/have an aftermarket ecu with an extra input for a maf sensor. Which is probably availible considering twin turbo cars use 2 maf sensors if im not mistaken (flame suit on). Anyway, the idea is that a maf sensor could be installed and adapted to the venting outlet on a BOV and wired into the ECU. Then the secondary MAF would be calibrated and the ECU programmed to subtract the data of the BOV MAF sensor from the intake MAF sensor. Then when the BOV vented the ECU would be able to calculate how much air was actually being fed into the engine and thus delivering the proper fuel. This is probably way too complicated, but I have time and come up with these crazy ideas. Anybody with more technical knowledge than me please consider this and tell me if it is possible or just a pipe-dream.

good idea but I think people would agree

too much work for something that isn't as big of an issue as what people make it out to be.

yea i agree with you. but it is an intersting thought experiement

If you're that far into engine management it makes a lot more sense to just switch to speed/density and lose the MAF entirely.

Theoretically what you're saying is possible, I could see pulling it as a secondary fuel trim on the AEM or Hydra or a Motec, but it's way overboard. You could accomplish the same thing with a throttle-based fuel trim when you lift your foot.

What he said :)

Getting rid of the MAF and running MAP is the only reasonable way to do it.

gotcha. I don't know too much about the details of EM tuning, so this is what i had come up with due to my limited knowledge. I thought i recalled hearing that a MAF sensor is a better way to go than MAP but apparently im wrong if a MAP sensor will fix the issue. Thanks so much for the input guys!! glad there's no flaming going on cause im a "noob". This is what Nasioc should always be like. Intelligent questions followed by intelligent answers.

Technically MAF is a bit more accurate, but that's only really an issue for emissions purposes, where you want to maintain an exact mix under most circumstances. For performance purposes, we all just err a bit on the rich side anyway, and MAP-based tuning is perfectly consistent if not quite as accurate.

Oh, and I almost forgot...





STUPID NOOB!!! ;)
