What a nice car!!! I love the Dart!!! How much HP does it give?? Which are the technical specifications of that Slant? |

It occurred to me that with your ESC problems there maybe a glitch in the Accel system that may be slant related. The sbc ESC has a knock sensor . It is integeral to the system. Slants have solid lifters which "knock". You will have to disable the knock sensor or end up with the ECM retarding spark in response to lifter/rocker noise. Is there a chance it started then retarded itself till it stalled? Could this be the "loud exhaust" cause? |

Bed time reading last time was spent with the Accel manual. It sounds as if going after the idle air circuit first is a good thing. There are about six variables that need to be dealt with, and they are all related to the engine coolant temperature, and the idle target speed associated with the ECT. Unfortunately, Accel does not tell you in every case how the coeficient you program in effects the driving. They simply say it does, but not in which way under what conditions. In some cases they do tell you how the variable in question affects driving. For instance, there is a variable that modifies how fast the idle solenoid will try to recover from an idle target error. It says in the manual that the higher number lessens the swings in idle. So you have something to go on when you change something. But in the case of another constant which takes the agregate error over the life of the driving history, and then multiplies it by this variable, the manual does not state how this variable effects driving. They do tell you what it controls, but don;t tell which way to go with the coefficient to correct a certain kind problem. I am going to just play with it, and see I guess. After reading just a little bit, I can see that two hours on the dyno would just get you started. There are so many things to progrm in here. It has a lot of power and flexibility, but also requires that things be pulled in together and zeroed in on as you progress. |

Yes Sam, most of the time it takes atleast 5 or 6 hours & more like about 10 hours of tuning on a dyno when on a system & engine combo that is unfamiler. And the drivability is harder than the WOT tuning. Somethings you could look into is that the Dizzy is phazed properly ( Engine has the same timing the DFI says it sould have at all RPMS) & injector offsets are correct for the injectors being used. Of course there is way more than this, but these out of wack what tunning you get done will be a waste if not correct. But it will take some time no matter what. The fun is just starting. But atleast its tuning & not diagnosing now that it is running. A hole lot more enjoyable. Jess |

Here is something that may help out with the idleing. To set the idling let the engine get full temp, ajust base idle screw on throttle body until the DFI shows 7 to 10% is what the IAC is controling. Also before doing this Zero out your Idle Spark Table, than after IAC is set work with the Idle spark table to trim it out. Be sure your not lean at idle also. Jess |
