I don't think it's that easy, if you have a look at the MGC reference points it's all over the place with air flow being thrown out by the A2A intercooler, jumping from 300mgc to 600mgc in a split MS.

Is there any information anywhere to say how the ref pulses work (how long it uses these tables) or when it switches from table a to table b?

How is the MAf tuning and the A2A going VX L67 ?????

I will be looking onto the options of MAF and MAP soon for my setup using the A2A plate but my pipe work will be very short unlike a typical A2A system

Yeah It's getting there, I'm chasing my tail a bit & want to start back at scratch in a way but it's pretty close now just cold start issue I'm trying to get down pat, but it's hard not knowing how it all works in conjunction with each other & changed too many things possibly.

But yeah it does take quite some time to get all the areas 100%, your biggest issue will be until the code gets extended it's limited range to tune to!

Yeah i have had to go back to a old tune a few times now also..

Are the setup's your tuning a typical A2A system with a front mount or have you had a play with the A2A/W2A hybrid setup's ???

Haven't seen a setup like that before but would most likely be a bit easier then standard A2A & a bit harder than standard W2A, but should work pretty well!

But yeah done typical of both either A2A or W2A!
