i bought an 85 rx7 13b and made it turbo i put a garret t6 70 ar with intercooler blowof valve external wasgate aeromotive fuel pressure regulator. and the guy that did all the work for me told me that it would be a good idea to put 2 extra injectors and set them to open at 5k rpms so now it has 6 injectors.. now all this set up i got was used the guy that worked on my car had this set up on his 12a and sed that he ran low 12s he said he was running a microtech fuel managament fully tuned, this guy no longer works on my car for personel reasons..
the car doesnt run right obviously because its running on the stock ecu. i dont know to much about these cars im new at this thats why im asking for help.

can anybody tell me what ecu or fuel computer i can use, what do you guys recomend or whats everybody using out there....

another question is can i use a piggyback ecu like apexi or emanage will it work or do i need a full engine managament....

like i said before in the rotary world, im not looking for a full blown race car i just want a respectable street car i wana run like 12s if possible

any help would be appreciated

 

You'd half to ask around on a larger forum for compatibility but Maybe the turbo FC chips would work with your SA due to the fact they both house 13-Bs, you might have to change the injectors or somehting to make it work or more, heck, it could be plug and play but I can't help out with 1st gens much sorry.
