    So I took a look at your bin spark map and compared it to mine in various areas. Just looking at the two tables (to the untrained eye) they look different.........

    However, my spark timing cells were within .5*- 1.25*of yours in many many points! Mostly in the loaded areas where the truck is actually driven under towing conditions. This makes me happy! Makes me confident in what I was doing.

    I do have significant more timing in the lower rpm and lower loaded areas where a vacuum advance would be........but......

    I've been driving it alot and not getting one single knock count!

    That's fine, but now add a 10k load?

    The little differences your finding would probably not add up to that much at timing marks! Remember the cell your in is interpolated with four surrounding cells to come up with actual number, without bias factors.

    Learn to use the smooth tool, set to .50, start at bottom right cell and smooth, nothing should change, go across bottom row to left doing the same, one cell at a time. Now go back to bottom right and move up one row, one cell at a time up 100 MAP to top. Then do second row up from bottom. right to left, third row up, fourth and all. Leave all idle alone and same... now look at your graph or watch as you do this. You'll see how everthing comes closer together, looks smoother but interpolation will end up about same timing. Now when smooth if you find some knock in a cell, you can take out 1 degree from 3 rows and three columns, still smooth, not like what GM did and grab and area and YANK those weird spikes and valleys...

    Yeah, I haven't loaded it with 10k yet. I've been tuning it with my 10.5' camper on. Total weight is about 3k lbs. When I add the boat and full of gear I should be in the 9k range and this should be the most I'll tow.

    I should have been more specific too. I have the G3 switching adapter from Moates. I plan on having a few different maps.......one specifically for a "tow/haul" mode like the new trucks which drastically change my shift points and back off some timing. One for Unloaded operation, and who know's what else. I think I can have 16 different maps with the EX switch.

    I really appreciate your help with everything. If I get up in your area I owe you a beer! I'll check out the smoothing function and play with it.


    Next thing I want to go after is the small puff of black smoke during initial crank/startup when cold. It's never done this before. It's not causing a runability problem but it must be too rich on cranking.

    Edit:
    Here's my map with the smoothing at .85:
    .50 seemed to add a degree or more of timing in areas which I didn't want.




    Here's my setup:

    assuming $85 / $D8 is 64KB, then you'll have a max of 8 BINs with the G3.

    not a problem at all. you can pack a lot of stuff into 32KB of space.

    i'm currently transforming what used to be 32KB BINs into 64KB because i ran out of space for my mods in a 32KB BIN.

    I found a little something interesting on this. I had a "BCC Lookup" .xls file on my computer that says it's from the moates.net website.

    my BCC BANC say's it's a D8 I.D. also. hmmm.....also says a 1991 K2500....not quite right for mine, but....

    D8 BANC 32.00 KB 1991 33653 16175267 16147060 5268 5161 K2 L19 7.4 MT1 AUTO 5X2



    A quick peak on the net didn't find a D8 xdf on the net. Maybe I should learn some hack stuff. Sounds pretty time consuming to do the hack stuff though?

    Maybe you should read this thread from first post? Pretty much explains how $85 turned into $D8...

    Then catch up to todays technoligy:

    No need to re-read.

    I just found something on my computer and thought I'd share what it was.

    I donated yesterday to help you continue with today's technology.
    Bravo. Keep it up!

    Sooo... My $85 mask is now $D8 with the same XDF? I really need to start on this 7060 now that my suburban is together and cranked up, but it's been a year since I've had my head wrapped around TBI tuning the last time.

    Thanks Mark. They are referring to PE as "WOT mode" correct? I need to make sure it's off before I start on this thing...

    Right, PE is titled WOT in this mask, I don't know why, just what the original author started with. I think next time I work on it I'll change it to PE.

    Turning off PE just gives you more opportunity to get more BLM cells filled in data logging.

    It's easy enough to turn off, I might as well. Still not sure if I'll do it via BLMs or my LC1 Wideband... With the excel correction sheet, the BLM way seems fairly simple and maybe even easier.
