ok, preliminary fuel tuning has me in the ball park at this point. the base map i got to start with was pig rich, EVERYWHERE!!!!. i've got 20 plates with a closed end cap on the old e-pipe, and making 107 hp and 115 tq on a 5th gear run. the graphs aren't that pretty and i've not done any spark tuning yet. i hope that there is more in there, but 'ill report again after i get the spark timing worked out and the final tune done.

I will be disappointed if you don't find more. I would be looking at the pipe for more; might need more T/B. Love to see a sheet.

i went from 14 plates up to 28 plates on the pipe, couldn't seem to find anything there, 50mm tb was all i could afford. as i said before, the base tune was super rich all over, i'm also not real happy about what the spark timing tables look like, but it was good enough to get it to start and run, so when i get a bit more time, i'll get back to working the spark and hope that i can get more. i will post up graphs once i get things closer to correct or if i get stumped on something, or once i'm done and happy..
