ok i don't have a honda so i can't use crome, hondata and whatever other kind of ecu management honda has so i need to "fool" my ecu into thinking that everything is ok with the fuel trims on my toyota since i'm going turbo.

the ecu will need to see a good mixture a/f(14.7:1) so it doesn't go into limp mode or tries to lean out the fuel when adding boost. now the qestion is how can i do this?

i saw the o2 sensor simulators but the only ones i was able to find were only for the secondary o2 sensor to fool the ecu into thinking that the cat. converter is working properlly, just in case you have a bad one or a test pipe.

i need both o2 sensors simulated for the ecu to see a perfect working engine and then add the fuel with the piggyback computer(emanage, yeah i know you hate).

so does anyone know how i can do such a thing?

 

why not use the new aem piggyback unit designed for obd2 cars? they dont have a plug and play for your car but you can hardwire it in.
