My Expy acceleration video

[toms89]

I uploaded a video I just shot tonight. I was holding camera so sorry about the quality and focus.

I was going up a slight incline and was initially on the side of the road so I hesitated for a moment until I was sure she was pointed straight.

The boring details:

The motor has been going dead lean on the shifts. Still not sure why this is happening but believe the tranny is hitting some kind of limit which signals the ecu to cut fuel. I loaded my new tune re-enableing torque reduction (limits power on shift) hoping it would keep the ecu from cutting fuel. This did help as it was far less noticable but it is still cutting fuel . After it cuts fuel it takes some time to recover....not obvious on video but it can easily be felt.

Watch the needle on the wide band gauge on the shift. The 5:00 position is 19 to 1 air/fuel and that is as far as the gauge reads. At full throttle it should remain at the 10:00 position as this is 11.5 to 1.

UGH! love that sound dude! gives me a woody everytime! yeah thats weird that the gauge dose that. is it cause there is no fuel going into the engine during a shift or is just something the gauge dose?

The gauge is accurate...the ecu is cutting fuel?! Datalogging confirmed it just not sure why yet.
