Best setup for 2G MAF and vented BOV

[Kurt04]

I know where I can get a 2G MAF and a Turbo SX RFL for cheap. So how can I make those work together. Also is 550 injectors or ECU mods the only ways to compensate for the 2G MAF?

BTW I have searched and can't find the anwsers I'm looking for.

If it's a good deal jump on it. If you have a EPROM ECU it's best to compensate for the 2G MAS at the ECU. But I've read that using 550cc injectors will get to pretty close as well.

buy some sort of Air fuel controller first, like a piggyback from HKS and/or Apexi. either/or will work and actually the HKS digital AFR is a little cheaper but has less features than the Apexi but continuously monitors and adjust the signal through a built in CPU. Apexi has 2 settings and a graphic readout. high and low, one for race and one for street, but others will dissagree and state one setting can be used for any condition. its up to you. i would hold off on the injectors until you need them your stock 440's are good for 300+. there are other things that you could buy for the price of injectors.

What's wrong with your stock BOV?

There is no real way to keep the stock air metering setup and run a vented bov correctly.

Daniel is right! you will need some sort of fuel management system for venting the BOV. Between shifts, the car will stall due to the ECU "adding fuel" for the "uncounted" air from the BOV return tube. This richen conditions stalls the engine.(fuel but no air)

I have 550cc injectors, Apexi S-AFC and a Greddy type S bov. I recently changed from a modified bov ( http://www.gusmahon.org/html/Talon BOV.htm )
I modfied 2 1G bov to hold 20 psi, I give one to Doug (here on DSMtuners) and I have one left. Anyone want it can have it.

I don't like the mounting flange for the turbo xs and HKS bov.

Couple things to correct in your post. The high and low settings on the SAFC are not 2 individually set fuel maps(Indicated by your statement of one for race and one for street.) The high and low settings are used by the ECU to switch the fuel curve between part throttle, and WOT. Also, I would not recommend stock "450's" for 300+whp.

If i had a 1g, I would just run 1g bov, and a 2g maf.

"Though I want to vent so my bov can be louder"
Well buy a gm maf and maft translator!

GSX4LIFE i appreciate the correction. and the way he's talking though about venting with stock i still don't think he should get that far into the fuel until he's ready.
