    After much consideration I came to the same conclusion. Luckily for me, looks like that particular save didn't take. When I went in to modify it, found that the FA mix was still 14.68. Going to leave that one alone. Starting to think that the Mileage was down due to mileage WAS down due to the extreme cold. Danged thing takes forever to warm up compared to my own electric fan having truck. It's really getting to be time to install electric fans on it, just gotta convince Pop that it needs to be done. Thanks.

    OK, next challenge. Found that the max retard was set to 8 degrees, and I was hitting it. Adjusted the max retard to 12 degrees and backed my high octane table back 3 degrees. I've lost power across the board, but am now getting a max retard of 8.7 degrees. Before this latest adjust I was able to spin tires through first and into second, and flooring it at 70MPH pushed you back in the seat, and it's not quite doing that now.

    Looking at the data logs, I see that the same timing tables are being used under different load situations, meaning that the timing will be in a particular cell both when there is no retard, and when retardation is close to max. This tells me that there is some other field that affects this. Can anyone point me in the right direction on which other table I need to be looking at? Ideally I'd like to see timing retarded around 6-8 degrees while running 87 octane, the idea being that I could run one set of timing maps, with the computer retarding timing to compensate for 87 vs 93 octane. So, I need to find whatever other table is adjusting the final timing in relation to, say, throttle position, so I can figure out what adjustments need to be made to get the maximum possible timing regardless of octane rating, with some insurance to boot.

    Comments or suggestions? Thanks.

    Telco,

    You may have to log the spark pids: the pids whose names begin with "EST_".

    These should show you where the timing is coming from or going to.

    Excellent, thanks. I'll work on that, be a while before I get to it and get back on here though.

    K, I pulled the info with the EST logs, and don't see what I need to adjust. And, it pulled even more timing on the latest run. Bounced off 12 degrees of retard this time, but think it just barely went past 12 degrees. I can email a copy of my current tune and log if anyone cares to assist with this. Thanks.

    How do I go about posting the files? I can email, but have never posted anything other than a picture.

    Superior! This is the first board I've ever been on that allows a direct attachment upload. Here's the file, and thanks for any advice.
