lets talk MAF(S)....

so when does the 1g maf become a restriction or "problem" when it comes to HP? when will an upgrade be needed if it is at all? thanks

It becomes an issue when you cant run any more boost without it causing fuel cut. People have made 250+whp easy on the 1g maf. I woudnt upgrade it till it becomes an issue.

im looking at a 20G setup for the long term plans so i take it the 1gmaf will only go so far with that setup....what options do i have to overcome this? i know a 2g maf is a start but not much from there. thanks

Well, you have a few options. 1. You can go with a maf-t + gm maf, mafs are easy and cheap to replace, you can vent if you wish, but I've heard of issues with inconsistent tuning. 2.You can go with a standalone, aem, haltech, or my personal favorite: Megasquirt. Completely erases the maf, but its gonna cost some $$$ (or only 200 for the MS )and even more $$$ to tune it. Or 3. The route I'm going: DS-MAP. Its a re-write of the ecu which converts it to speed density. You need some gm sensors, an ostrich and a socketed ECU. Not as many goodies as a 'full' standalone, but its much easier to get up and running, and you get the advantage of plug and play with your stock harness.

To the O.P.

I would love to see some pics of your ride. I think it is safe to say that there aren't to many '90 Spyder AWD around.

i listed it as that because i kinda street race and i know a GOOD amount of people on here which is why my locations dont match up either....there is a method to my madness .

But when does the Hz signal of the 1g (and 2g) become unreliable (what airspeed)? You can deal with fuel cut with a chipped ECU or DSMlink, but I imagine the speed sensor has a limit (the IAT and baro sensors shouldn't).

The sensors become a limit when you start flowing a certain amount of air(hz) not when you make a certain amount of power. I will try to find somebody on link forums that over ran a 1g maf but I doubt I will since most people on there upgrade to a gm maf before its limits.

Or a 2g, or an evo8. Must be some intense street races on a 1g maf.
