If you have the headwork, cam, and exhaust work to necessitate that extra flow, then you will need a chip to make it work properly. Yes people get it to work without software but they are fooling themselves. Since AFM's wear out and are expensive, people usually wont buy one new or remanufactured. Replacing a worn M20 AFM with a good working M30 AFM will feel like a nice gain just for the fact that you have a properly working AFM again. There is also the quicker throttle response that comes from the larger diameter of the AFM. The increased response makes you believe you have come across some amazing modification that you should have done a long time ago but in reality, it just FEELS faster. The MAF conversion guys can't figure this out.
Bottom line:
If you are trying to restore your M20 to have really crisp throttle response and run nice and clean, then suck it up and buy a new M20 AFM.
If you plan on running some sort of programmable ECU. Feel free to get whatever AFM or MAF, and have fun getting the thing to run right consistently.
If you just want to bolt up an M30 AFM, you can do it, but you also might not get it to run right. -
it's not much of an upgrade. most of the time, it will just make your car run like shit. The other %1, you gain like 4hp. maybe.
if you did a bunch of work to the engine, and then ran it on *any* AFM, much less an M30 AFM, you've just wasted a bunch of time/money.Comment

thanks, i apreciate the info. about how much does a stock afm cost?Comment

new is way too much to be worth it. you can get a Miller MAF and WAR chip for less than the cost of a new AFM. But a good used one is between $35-75.Comment

I have seen remanufactured AFM's go for as low as $125. My own experiences with a remanufactured AFM are all positive so far.Comment
