ok i just read the m2 site that their ecus are not made for ported engines? is that true? im looking at a stage 3 ecu.
also does the pettit unlimited work with street port then?

dont u hate it when u try to do a search using "m2" cuz the site dont allow less then 3 letters. so ghey.

 

I used to run with a M2 Stage 3 and they are not programmed for any type of ported engine. Try your search next time as Mostly Mazda/ Tuned ECU.

 

The pettit ecu are can be programmed for Full bolt on, ported motor and 14.7psi.

 

The Pettit's ECU is pretty good. My friend was running with that ECU for a little while, however, he now has a Haltech. He ran with a ported motor and 17psi on his FD. He had a lot of work done on his car and he liked the ECU. Just get the unlimited chip.
