MAF sensor modification mx5

[madmanstiff]

Hi guys.
I'm in the process of modifying my mx 5, mk1, 1.6. I'm building up to eventually fitting a super charger. I've been looking at basic cheap induction modifications so that I can make the exhaust modifications worth while before the charger is fitted. The big point that I can see that needs altering is the very restrictive MAF sensor. I've read that the rx7 sensor will literally plug and play but I still feel this is slightly restrictive as it works on the same principle of the air pushing past the flap. Does anybody know of any less restrictive sensors that "plug&play" with the standard ecu?

It's not really that restrictive at base power levels. You'd get much bigger gains just from having the stock AFM tuned properly. Even them the gains for the outlay are very small.

p.s. It's an AFM i.e. Air Flow Meter, not a MAF i.e. Mass Air Flow sensor

What Lazza said, it's not as restrictive as it looks, (and it's an AFM not a MAF). Also the RX7 unit isn't PnP, you need to adjust the clockspring, and without a wideband you're doing that completely blind, you're more likely to have a performance detriment than improvement.

BLiNK motorsport can tune your OEM AFM which releases a few HP.
