I have a new intake manifold and BBK 75mm throttle body im wondering if i can just get rid of they ISC or if it will be just a big problem. I dont have it hooked up now because i want to buy a new re worked BBK throttle body from FFTEC and they also sell the ISC adapter. Im just short on cash right now so for right now is there a way to disable it ? I have it set with the throttle cable right now and the screw on the TB to set idle like it was a old carburatored. Anyway anyone has an input on the situation much appreciated. I just want to get it to run decently until i get the money for that new TB and adapter. I have ECU flash so if theres anything in that i can change then let me know thanks.

 

you'll probably throw a cell, but assuming it doesn't affect anything else you could just turn up your idle.

 

Thats what i figured i was just unsure if its going to make my car a B*tch to tune and get right.

 

It may require constant adjustment of the screw and the AC will make it stall. I would be very curious on the outcome, but you will have to block the stepper port somehow.

 

Well when i did my manifold i got it flanged for the big bolt mustang style. I bought a BBK 75mm like the one AMS carry's. I have the TPS sensor all set i wired it with the wire schematics for both. Any way im either thinking about buy one from FFTEC that is re-worked with the adapter plate or i was looking in summit at the Holley TB's and they have High Flow EFI apllications for the mustang and there rollers are sealed so there shouldnt be any boost leakage. I pressure tested my hot side intercooler pipe to the manifold and i didnt have any leaks so its fine for now until i get cash. I was just curious so i could get it running to F around in it again for the first time in a while.

 

Are there values that anyone knows that would disable to ISC so the ECU knows its not there ? Or will it not affect anything if i leave it as is seeing it that when the car goes the adjust idle with the ISC that its just not there and wont do anything except probably throw a CEL ?
