I have a cold air intake in my RX8. I hear it causes crazy problems for the MAF sensor or something of that nature when combined with the AP. But if I buy it from MM he can send me a special map that adapts to the intake? And now i hear something is wrong with the stock coils, or is that just for force fed RX8's? Just need to know: Cold air intake on mine, I buy an AP from MM, out of the box what do I need to do? Thanks much.

The thing to keep in mind is that you're not changing anything on your car with the AP. Your hardware that works today, will be used exactly the same once you flash with the AP. The only thing that changes is the map used in your PCM.
So if it works now, it should work after. If not, talk to Jeff and he can fix it.
The FI people had problems because most of our systems used to be MAP based once the car got into boost. MAP mode doesn't use the MAF sensor, so it didn't really matter how our intakes were setup. Once we were using MAF 100% of the time, the airflow across the MAF sensor mattered, and if not setup properly, the car assumed a LOT of air flowed and we ended up with a rich (safe) AFR in boost.

MM,
Can you send me the 3V series with the dwell adjusted
the car is too lean with the 5V map and a screen installed before the MAF
. i am getting high to mid 12's under boost with that .
I also emailed ya
Thanks

I dont know if you tried other 5v maps but the last one shown on my AP was 5v_6a. I think you made some tunes on that map. The unstable ilding was becuase there was no screen installed that day. I just got a datalogger so I'll log somthing for you to work on~
Thanks
Thanks

I got a response about the Wednesday shipping date, but none on the shipping options. I was hoping to have it sent by UPS AIR, or FedEx ground, but if it's too late, that's perfectly fine. I think we have that problem again where some emails filter yours out if you send from one of your accounts and the name doesn't match?
Can you resend anything you may have sent me? Thanks!
