i herd different stories all the time,.......i have dp,mp,cat-back, smic, and intake so far, i need a ecu that fits
thanks

 

you have all this and no ECU mod??

its people like you that give FD RX-7s an "unreliable" rep.

its pretty damn amazing you havnt blown your engine yet.

 

and no, i woulnt reccomend running the M2 Stage III with your setup, unless you keep it at 10 PSI. otherwise, go with a Pettit Unlimited. i would not reccomend an Apex PFC since it is obvious you dont know too much about the car.

get an ECU fast!

 

yes the car is running at 10 psi...i bought the car recently and the previous owner did the mods, i know i need a ecu, and i know i'm lucky the engine has'nt popped yet heh.

 

the M2 Stage 3 and Pettit Unlimited are pretty much going to be similar. If you want to get into the real technical nitty gritty, the fuel maps on the M2 is more conservative, meaning they will not run the injectors at 100% duty cycle. I think the highest it will go is 90%.

With the Pettit unlimited, I believe they run higher duty cycles, maybe the full 100%? Which for prolonged periods is obviously not good.

I know lots of people with the M2 Stage 3 though, that have midpipe, downpipe, street port, intercooler, all the mods, making 340-360rwhp without any problems. But these people also know what they're doing, and usually dyno tune with the wide lambda, and usually have at least an upgraded fuel pump like the Walbro or Bosch, and maybe even fuel pressure regulator, or the SAFC.

It really depends what you want to do. With your mods and moderate boost levels, you should be able to make 290-310rwhp without too much difficulty.

If you want to start making above 320rwhp, you have to really take a fine look at the fuel system...especially the fuel pump, fuel filter, and injectors. The Pettit ECU or M2 ECU in and of itself is not the safest way to do things for higher horse power cars, since you'd be running right on the edge...and anything such as a clogged filter, or tired injectors, or tired fuel pump, or bad gas, could put you over that line. Better safe than sorry right?

 

YES!

 

No! I live about fifteen minutes from m2. Before I bought my power fc I asked the owner of m2 that very same question. M2 dose not sell midpipes, they do not recommend them, and their reprogramned ecu will not properly support them. I have a midpipe on my car and after putting it on I would not recommend running one without a standalone ecu. The reason I bought my power fc is I knew that I wasn't going to be happy with just one setup. You know how it is you modify something and you think oh my god this thing is fast and after about a month your looking for more. Well you can't do that with a reprogramned ecu. You can only go so far with them. Why are you guys still wasting your money on reprogramed ecu's?

 

ok thanks,
