Over the weekend I was helping tune a friends car.

Everything is pretty much good except when he steps on the gas and lets out the clutch to get the car moving. It basically jerks around and hesitates until it gets moving a little bit. Once its moving its ok, shifts fine and all that good stuff :-)

I noticed w/ datamaster that when in closed loop the O2 readings plummit and I have a feeling the car isnt getting enough fuel and that is what is causing the stumbling problem. What table specificly do I need to change and or play with to remedy this problem. I have changed almost all the Accel Enrich tables in Tunercat and Tunerpro and havent seen any noticeable changes with regards to the problem. Could someone point me in the right direction?

One other thing, the speedo wasnt working during all of this....could that have been part of the problem? Better yet, what effect does a none functioning speedo have on the tuning process. BTW, this is a 355 with 200cc heads and a CC306 cam.

I do have datamaster scans and csv docs I can email if anyone is interested.
