Base map...that explains the nasty looking graph.

I'm going to give you the same lecture I told the other guy in the dynos section (the bitch didn't want to listen to me :P )...
You've got a dyno - use it wisely.
Ignore the AFR's - it's going to mislead you; I've had the DynoJet spit out fucked up readings once - it showed 11.0 on one run, and they it showed 13.0 on the next run - I was only adjusting ignition timing.
Adjust fuel - check the power output.
Adjust the ignition timing - check the power output.
If you're going in the right direction, you WILL GAIN POWER.
Adjust ignition timing in increments of 2 degrees - if you're paranoid, go 1 degree, but it'll take a lot longer.
If you're ignition timing is too advance, you'll hit preignition and the power will drop noticeably.
If you are too lean, the power will drop.
If you are too rich, the power will drop.
You get the picture...
Once you get best power on the dyno, add a little more fuel and drop the ignition timing by 2 - 3 degrees - this will give you a safety margin on the street.

This is one of the biggest secrets when dyno tuning.
The dyno can be a great tool for tuning, if you use it wisely.
I used to not tell people how to do this, but too many people are wasting money not being able to do this...

replaced spark plugs, same issue. Going to work my way up and check spark at the coils and such.


Stay tuned for more confusion and frustration

ok i think i got this figured out. Somehow I wasn't thinking when i swapped egt sensors to take into account that the gauge would be swapped differently than i think,
Anyway waiting on a new egt sensor to be sure.

A major dee dee dee
Could have been worse i guess
