maf 2002 zteke184 02-19-2004, 07:59 AM um...10mm wider diameter ;) that is to allow greater flow with less restriction. as for which one is better...6 of one half dozen of the other V6toZ28 02-19-2004, 10:58 AM Keep in mind the MAF is a measuring device and the PCM is calibrated to read it's inputs ... change the MAF and the inputs are no longer accurate and the PCM can no longer make accurate AF/R adjustments ... I lost power on the dyno with every AM MAF I tried ... upwards of 23 rwhp in one case ... Friscoz28 02-19-2004, 02:30 PM so i shouldnt put a maf? Aklaim 02-19-2004, 02:35 PM The stock maf is not a restriction. It is capable of well over 500hp. There are lots of big power motors using the stock maf. mullettour 02-19-2004, 02:44 PM Will it hurt or help to descreen the maf? Aklaim 02-19-2004, 02:48 PM Leave the screen on. I breaks up the turbulence of the air flow coming into the engine. Have you ever taken a screen off of a faucet and seen how crappy the water comes out? The same principle applies here. Friscoz28 02-19-2004, 03:46 PM is there a difference between the slp maf and the granatelli brand? V6toZ28 02-19-2004, 10:38 PM Originally posted by Friscoz28 is there a difference between the slp maf and the granatelli brand? One more time ... the MAF is a measuring device and the PCM is calibrated to read it's inputs ... change the MAF and the inputs are no longer accurate and the PCM can no longer make accurate AF/R adjustments ... Specifically, the PCM is calibrated to the stock MAF ... rixz28 02-21-2004, 05:05 PM Doesn't the computer "learn" about the new MAF and make adjustments? I put in a SLP 85mm MAF with the new lid and noticed a big SOTP difference. SLP was $175, Granatelli is like $300 or something like that. Chopstix 02-21-2004, 07:10 PM The SLP MAF is the same MAF put on 6.0L vehicles but they are recalibrated to work with the factory ECU AL SS590 M6 02-22-2004, 01:54 AM Originally posted by rixz28 Doesn't the computer "learn" about the new MAF and make adjustments? I put in a SLP 85mm MAF with the new lid and noticed a big SOTP difference. SLP was $175, Granatelli is like $300 or something like that. Seat of the pants is absolutely the worst dyno ever built. Take it to the track with the stock MAF then change it to the new one. Back to back runs. Aftermarket MAFs are the biggest waste of money on a stock or near stock LS1 that anyone ever came up with. Heck you might as well go out and buy a Tornado. Look at my sig. That's with a stock motor and a stock MAF. | ||
