    Download and install this keyboard test software to check if the keyboard is sending F7 key events.

    Yep. That was what it was. The F7 key was sticking. Thanks so much. Now if I can get the table close enough to get the car started. Thanks again.

    I agree. Talk about customer service. BTW Jeff, thanks for getting the base tune done for me. I have been reading up on their sticky's as much as I can. Hoping to understand all this stuff soon. Tomorrow I am going to ad or subtract 10,20, 30 percent fuel until I can get it to the point of starting and running at least decent. The E85 and 160lb injectors kind of throws things for a loop.

    Ha, lucky guess on my part!

    Glad you've got it sorted, do you have another PC you could adjust the tune on then just use your laptop with the stuck key to flash/log?

    Have you setup your IFR and related injector tables?

    The only injector table we set was the IFR table. He is running 160 lb/hr low impedence injectors through resistors for his setup. We have no idea about how any of the other injector data tables would need to be changed or what info to plug into the parameters.

    I went ahead and messed with the tune and I got it to start and run better subtracting 30% from the Main VE Table. I did it 10% at a time until 20 and then went in 5% increments for a total of 30%. I guess you only need to run 30% more fuel to your VE table if you are using stock injectors? The only thing I can think of is since I have 160lb injectors the fuel tables will still be pretty close to stock?

    Even with that I couldn't get it to run more than about 5-10 seconds and it still would die immediately if I tried to use the throttle at all. I tried raising and lowering the fuel pressure on the regulator a little and it didn't make much difference. 2am I called it quits.

    You can adjust the fuel pressure for diagnostic purposes to see which way the engine wants to go (richer/leaner). After you figure out if it wants to be richer or leaner, you need to put the fuel pressure somewhere and leave it and then set the IFR table to match the new pressure. Then adjust your VE table up or down a bit. You need to get your wideband interfaced with the software.

    Did you post your tune? Maybe I missed it. Who makes the injectors? What values did you put into table B4001 and the rest of the injector parameters? Is this a 0411 ecm? Car sounds like a beast.
