800cc secondarys+safc= no problems????
 

hi, i just want to know if the safc can control 800cc injectors, im gonna mount a to4 on my rex and i was going to go 800cc instead of 720cc but i want to know first if the safc will have no problem.

thanks

the question is the the stock ecu can handle those injectors, because the Safc all it does is invert the AFM signal so the ecu think that there less or more air going to the motor. if you have a S4 rx7(87-88) you can get a Rtec 2.0 chip for the stock ecu and use it with the Safc and you should be good, but if you have a S5 (89-91) well theres no chip for those yet

Just in the secondaries? Or all the way around? If you're talking about just in the secondaries, you'll be fine. If you're putting 800's in the primaries, you could have issues.

only the secondary's, the primaries will remain stock.
