After chasing sync problems for a while I found out my CAS was causing the issue after trying 3 I found a good one. Now my issue is in tunerstudio my afrs are sluggish and usually stay solid at 12 something and randomly when I'm hitting the throttle it runs to 16 then back to 12. It doesn't matter how I adjust the bins it doesn't react. In logworks software it acts fine and reacts normal but since I lack an in car gauge and don't have another serial to usb cable yet it makes tuning horrible. I will try recalibrating it tomorrow and go from there. Anyone got any ideas?

 

If they are staying at 12 something, you may be in closed loop(? i get them confused) and the ECU may be using the AFR table to get your AFR.

Are you stabbing the throttle when it goes lean momentarily? that could be your acceleration enrichment.

do you have a laptop you can use as a gauge?

 

Yeah I use my laptop to tune with but the gauge in megasquirt reacts different compared to when I hook up the wideband to the laptop and use the gauge in logworks software.

 

Did you calibrate the MS for that wideband?

I feel like an idiot..... I think I completely missed it. I know I configured it in megatune configurator. Ken I can't thank you enough. Need to slow down on reading, missed it in Aarons write up.
