Hello everyone i have a 91 crx si with a d16y8 thats turboed with a t3 turbo. im using an safc with 450cc injectors and i even have an fmu. it will run rich up to 5200 rpms and then fuel cut will hit. thats only under full throttle. im also using an 89 intergra ecu this happens even lower on the stock si computer. can someone help me. why is it cutting at 5200rpms

 

i dont think you should be runing an fmu if you have the afc. defeats the purpose of the hack

 

i kind of figured i didnt need the fmu so i did take it off and im still getting fuel cut or what ever you want to call it. does any body know what the deal is. im thinking its my ecu. maybe i need to get a fuel cut defenser or an stand alone

 

Did you set your S-AFC right??
from 1000-8000 rpm's?

 

check the ecu maybe its an automatic ecu those have the fuel cut offs and rev limiters and stuff.

 

the ecu is the right one. its out of an 89 integra but it does the same thing with the 91 si ecu tooo. safc is set pretty good. it did the same thing with the fmu and stock injectors

 

i guess nobody knows what 's going on with this.

 

yeah i still have the stock pump on i have a 255 walboro that i need to put on but i kinda got discoraged with the fuel cut. you think its the pump
