As above really.

I have an Apexi PFC and was wondering if i really need to go through the hassle and expense of either an ECU swap or the MAF sim conversion if I want to run a rotated garret GT30R setup.

The Car is a UK MY1999 with a fully built forged engine STI V heads and valve train, apexi 740cc injectors, APS cold air intake and a blitz steel mesh filter.

probably need a mafsim, as big turbos can have adverse effects on the maf

 

You stand a decent chance of maxing a maf out on a 30r. You can get a bigger pipe and rescale it but going for the sim would be you best option. It does anyway with the jerky throttle response when you lift off too.

 

Is there a mafsim that is plug and play with the PFC?

 

plug and play as much as it needs mapping for it and setting up.
