AFC with a FCD?

[Wade T]

I've hear it's not possible to have a FCD installed with a AFC or the like since they're both tapped into the AFM signal. I'm getting close to FC with the Lexus AFM and need to emliminate it. Any input would be great!
Thanks.

do you have an afc already? if so, is it tuned at all?

its unusual for you to hit fc on the lexus afm unless you are running really high boost or a large turbo. sounds like you may have a boost leak.

and no, ive never been a fan of the fcd, with or without an afc.

The turbo is a PT61 the boost level around 18psi. At high boost the AFC is -16% all the way to 7k. I run a RRFPR along with 550s which is why so much fuel has to be taken out. I just don't want to hit fuel cut if any more boost is added.
