I have been trying to get my conversion done in time for Okteenerfest. I have run up against a brick wall and just cant seem to figure out what i am doing wrong.
If anyone can help me by looking at my tune files or providing insight it will be very much appreciated. I can get th car to idle but nothing beyond that. Any use of the throttle is less than impressive and almost useless. Meaning it bogs down and does not accelerate at all. I have no clue what i am missing. 2056 with new low impeadance injectors. Bosch Wideband O2 sensor. Really need some suggestions. Not sure if i can post the tune files here. But will try. |

I'd have a crack at putting the correct injector flow rate in the software.
Pretty sure you'll find static flow is the value used. Also you don't have a barometric sensor connected so get rid of those values at turn the option off. Also worth Turning off cold start corrections off for your initial tune. I can't see what you're doing for lambda sensor. Wired to the ecu? After that it should be slightly more manageable |

I'd have a crack at putting the correct injector flow rate in the software. Pretty sure you'll find static flow is the value used. Static value is almost always used. (IMG:style_emoticons/default/smile.gif) Is there a "key-on" barometric pressure sensor option (using the MAP sensor)? OK so I have gone back through all of the advice given. While I thought I had it resolved, I a still not getting one of the injector banks to fire. Definitely only running on 2-cylinders. Seems like the INJ 2 bank Pin 10 is not putting out a ground signal. I have verified that the injectors are mechanically operational- The fire when given 12 V and a ground and I have spark at each plug. I have verified the wiring is correct and connections are in place from the injection to the AMP Seal Block. Switch out the wiring from side to side and the problem follows INJ 2 Pin 10 as moving INJ 1 from side to side results in operational injectors and firing. I have no concept in how my wiring can be faulty and I don't think there is a setting other than turning on sequential fire that would cause one of the injector banks not to fire at the same time. I have to think this is yet again a hardware problem? Unfortunately, it appears that way based on my read of your description. You checked to make sure the non-firing injectors have 12V at their connectors? And that the ground side of the injector connector has continuity all of the way to the MS connector? I'm reading the above like you did that, but just want to verify. Do you by chance have an oscilloscope? Or can you use another output rather than the one on Pin 10? |

I have checked all of the connections and wires. Comes down to all of the injectors will fire if 2 injectors are attached to INJ 1 wire. No injector will fire when attached to the INJ 2 ground. Because these are high impedance injectors I don't think the one operational channel can drive both banks. |
