Hi i just got a JDM MAZDA 88-91 RX-7 FC3S S5 13BT PAN SPEED RACING ECU and i wanted to know if any body has used it or has it on there fc3s TII?? Did you see a big defrences?? I had the n374 with a afc2 but i ended up blowing up my motor.. Any help thanks...

 

You blew up your motor! NOT COOL. How did that happen?

From what I remember reading some time ago is that you have to do a lot of things to get it working. It might not just be a plug n play sort of thing.

 

I was on top of 4th gear and when over 7500 my wideband was around 13.1 to 13.6 when the engine loss power i had stop boosting and when in to 5th she run fine until i tryed to boost aging thats when all hell broke lose.. She started to shack and had no power.. she did get me home.. I wont be doing that agian.. i hope the ecu is a plug n play bc it did i wont fine out till my new engine gets here.. I would have gone with rtek but they dont do the n374 ecus.. Thats what my car has in it right now........
