As above. I want to correct the MAF reading after fitting an APS CAK.

MY98 WRX.

Didn't know they did an APS CAK for pre 99 cars.... interesting.

I would have thought that the calibartion would require adjustment rather than the whole curve being moved up by a certain voltage (i.e the curve shape adjusting). So an HKS AFR would not be ideal.

What ECU do you have?

Tone,

The ECU is by Zerosports and came with the turbo, downpipe, up-pipe etc.

I was thinking of one of the devices that allows adjustment at 200rpm intervals etc.

S-AFC?
