Bigger AFM

The exhaust side of my S14 if almost sorted, but the inlet is a bit choked. Can get a MAF from a VG20 which I believe is the same as the RB25DET unit. Nice 80mm hole and 3 pin plug, easy to convert to the std S14 4 pin-3 wire plug. While I am at it, also fitting a bigger throttle body, also about 80mm in size.

The part no for the MAF is : 22680 31u00 a36-608 e60

Lots of stuff on Google, bit nothing definite on a SR swop. Any tried this one b4?

From what I've read is that you need to "update" the ECU in order to read the new MAF... its like changing injectors can't just plug a bigger one in
