AFR looks wack> whats going on?

[brusk]

What AFR's are you looking at that you don't like?

I'm seeing 13's down to mid 11's when it's floored and past the spool up RPM's.

- sort by Accel Pedal Position.
- Delete all cells less than 90% Accel Pedal Position
- Resort by time
- that will leave you with just the pulls

2) Your actual TPS position is all over the place. Your traction control is pulling back power due to wheel slippage. You must have had DSC engaged. It needs to be fully off.

3) One way to see if the engine is doing what it should is to log both the requested value of a parameter and the parameter. If they match well, the tune is working. For example, log the requested AFR and the actual AFR to see how they match. Same with HPFP, Load, Boost, etc. It helps to plot the requested and actual using an XY chart with rpm on the X-axis.

thank you.. your recommendations are appreciated.

traction control was off.. i have an error code relating to the throttle valve going in to get it checked out..
will do more logging soon, and i will definitely clean up the logs next time, using mac and attempting to read logs is a PITA if you don't have a spreadsheet app.. do you know of a decent grapher for mac?
