Thread starter davidalindsey Start date Oct 9, Just pondering if there is anyway to "disable" fuel cut under deceleration as in no fuel cut on decel, just letting the remaining unburnt fuel exit out the back? The reason I ask is cause back when i had an SRT-4, the exhaust just sounded so bad-ass with the loud rumble, popping, and gurggles when slowing down or letting off the accelerator.
I know this was due to SRT4s just have a cat, a resonator, and no muffler, that and no fuel cut on decel. My SRT4 in the video does have a hks carbon Ti canister muffler. So is there anyway to alter the fuel maps or some how letting a little more fuel in while letting off the accelerator?

You're going to shoot flames out of the pipe. Aproductions Proven Member. Not as much to shoot flames out the back, just enough to make it rumble. Because the turbo DSM's are set up to run quite rich on the top end, no harm is done expect possibly in extreme circumstances. Important: Do not use any device to eliminate fuel cut.
Fuel cut is there for a reason. If you are hitting fuel cut the ECU believes that you are moving more air than the fuel system can safely deliver. If you are having to eliminate fuel cut with some sort of defender either you have an inadequate fuel system, inadequate tuning tools, or a leak somewhere.
DO NOT decrease air counts without adding more fuel per air count. Upvote 0. Barlow Proven Member. With a bad idle switch you ecu doesn't know when the car is idling. Fix that and your idle souls steady out. Thanks for the quick replies! I've been searching around and i cant seem to find a new one. Any ideas on where i can find one? I would check if it is working before you get a new one. Just hook a multimeter to it, and the other probe to a clean ground, and see if resistance changes with throttle.
Closed throttle should be a closed circuit and open throttle an open circuit. It also may simply need adjusting. If you disconnect the IPS the ECU doesn't know that the throttle is closed and the check for decel fuel cut fails which is what triggers idle surge. The fact it was surging says that the IPS is working. Now go find the real cause. Click to expand The ECU only checks to see if the current idle speed exceeds the thresholds when it sees that the throttle is closed.
I have a remanned ecu and its done the same thing with 3 different ones so i don't think its that. When i get the chance ll test both the idle switch and the isc. I tried to remove the isc but whoever had the car before me broke off the ends of one of the bolts so just the threads are left in. Ok Im gonna do a little update because I still haven't found the problem.
Throttle body is clean and valve is functioning properly. So that being said let me explain the problem a little more in depth. The simple answer is that because fuel cut is pre-programmed into the ECU , there is no method of disabling it.
There are no modifications that can do so, aside from an ECU upgrade that eliminates fuel cut. Upgraded fuel pumps, injectors, and fuel pressure regulators do nothing to avoid or eliminate fuel cut. That being said, there are some methods some cheap, some not of postponing fuel cut.
All the methods work on one principle: fooling the ECU into thinking there is less air entering the engine than, in fact, there is. This can be done by adding unmetered air, or by changing the sensor inputs used by the ECU to determine air mass.
