what level of ecu upgrade (piggy back)

i've got an fc 13b na with a mild street port, exhaust and intake.

i'm looking for a moderate tune with larger secrondary injectors.

would a piggy back system be sufficient for my setup?

also is the power fc compatible with the rx7 fc 86? i've got one in my fd. that would be some deep irony if it wasn't compatible. well a little bit.

Banzai makes an adapter to fit the PFC in the FC but Rtek 2.1 will do the job. a piggyback like an SAFC will also work but not as well as either of the above.

the cheaper being the Rtek but also much less efficient to tune with.

you also do not need larger secondaries, it will just make it more difficult to tune and be a waste of larger injectors. you will be hard pressed to make over 200whp without some serious modifications to where upgrading the fuel system would be necessary.

Greddy emanage maybe. It works with rotary engines and you can get the old emanage blue for about 250$.

ok i think rtek is what im looking for.

as long as i can increase the fuel flow of the stock injectors enough without hurting reliability.

rtek is the least involved plug and play,

and a more expensive option of a full stand alone i don't think is worth the time and money for a non turbo of that level.
