    Sorry for the late reply, didn't realize there was a second page. I'll get the logs this Monday and post them. Thanks for all your help

    Looks like it will be a week before I get the log files. The oil pan replacement has some hitches that I am working through.
    The engine is apart and I'm waiting on parts and the time to get back to it is holding up progress.
    I will send the files ASAP. Thanks for your time and knowldege.

    Hello Steveo,
    just got the car running today, but couldn't get the logger to connect when i was able to drive it in the yard at the shop. So I made a log file idling in my driveway. I don't know if it is enough to give a tutorial or not. If it is not i will send another file when I register the car. I noticed that the wideband readings on the gauge don't match the logger. Is that because the sampling speeds are different between the two, or is my formula in the logging program incorrect? The program won't allow me to attach a cscv file.How do i get it to you

    With minimal math in the scanner histogram, I disable dynamic blend, forcing MAF only and tune both MAF and VE at the same time. I do 99% of my tuning in MAF only mode.

    What parameters do you change to disable dynamic blend?

    Good afternoon all,
    I know i posted this a while back, but I'm not grasping this. I run so rich at idle that all you get is black smoke and my eyes burn. I tried increasing the ve cells at idle and decreasing. No change whatsoever. On the short log from last night, my injector pulse width is showing over 5ms. For a short time it was 39ms.my target AFR is showing 12.5 but i set it to 14.68. At idle the AFR is 9.0. I have the PCM set for speed density mode. What am I missing?
