When linked up and guages showing, bike running, showing target AFR of 13.84... Rear cylinder shows 13-14 afr. In the green.... Front cyl AFR shows 18-20 in the red!!!!!!!! Is this normal for the front cyl to be in the red when idleing???????
I'll hook the bike up again and check that the AFR's are around 19.3 with bike off.
The thing thats weird is when i check the corrections that auto tune makes it doesnt show anything about a really lean condition on the front cylinder. Front only showed 165 corrections...
Update..... Sent tmax my data logging, Corupted map. Spike or surge in system, checked all connections and reset new basemap. Sync'd 02 sensors and POOF problem gone. No check eng light at idle, clean AFR's at idle and at throttle, and the bike runs GREAT.... I changed the routing of the front 02 sensor wiring to under the tank, much cleaner and its away from the heat of the exhaust....
I was ready to throw the tmax to the highest bidder and buy somthing else...
I'll let this this thing work its magic and hopefully im back in business.....
