SERT VE Question
I'll be out datalogging tomorrow, to see where my VE tables compare to the Reference file I have loaded. I've read the SERT manual, read hundreds of posts here and yet there is one thing I don't understand. There are constant references to "Setting the AF to 13.x " Then tuning the VE tables. After which one would have to reset the AF table to 14.6 for closed loop mode. Why is this needed?
TIA.

O2 measuring device, such as a Dayton Twin Tec Twin Scan II+ with O2 sensors. By using the flat afr in conjuction with the Twin Scan II data logging you can determine how to establish front and rear cylinder VE. Tuning a bike on a dyno does the same thing with sniffers in the exhaust pipes, or 02 sensors in the head pipes on the newer models.
Without collecting data to compare target afr to actual afr, there is no way to accurately establish VE.
Datalogging isn't going to do you much good in trying to tune the bike unless you have established accurate VE tables. You can make any adjustments you want and see how they effect hp/tq, but that's a very hit/miss approach. Far better to establish actual VE values and then make af and timing changes.

The Data in the ECM will only tell you the AFR you are requesting in the Fuel Table...it will not tell you what the true AFR is coming out of the pipe so trying to set your ve table with out all the infornmation needed such as true AFR is a waste of time.
