Default Use a PnP as a parallel ECU

Is it posible use the PnP as a parallel ECU?????
I have a lot of problems with my Idle Speed.
I canīt move it down from 1400 rpm.

I thought that i can use the OEM Ecu to the Idle control and the PNP for the rest of things.

Is it posible????

You probably could with enough work, but I'd rather fix the idle problem.

The idle problem is either
tune related

If mechanical, then going to the stock computer for idle only does nothing to solve the problem.
If tune related, you can just fix the tune.

With that high an idle you probably have an intake leak passed the throttle body.

Throw in the stock ecu and idle it, if it's fixed, that's one thing, but I'm betting it'll still be there.

I zip tied a fuel hose to my throttle cable which I later found out after removing and reinstalling the engine was pulling on it, giving me a high idle. That zip tie is no longer there.
