These figures seems a bit odd, pasotibbs.
Crank looks like a Prime table and same values allover Oil & Air T.
How did you end up w this?

It ends up like that when you load an old format map (lacking these tables) with a newer version of ECUControl, and save it again. These sections need to be filled in!

Yeah, these posts make me think I should be adjusting my tables for better starting, too. Also, since the O2 sensors need to be heated before starting the bike, and the Cal box is under the pillion seat, I am adding a voltmeter to my indicators because the battery voltage drops while they are heating, then bounces back, so I will know when it is okay to start.

Because I am using the LC-1 system, I was able to monitor the O2 sensors using Innovate's Logworks3, and the ECU using the Optimiser. What I discovered is that at 1100RPM (0,1), the AFR is ~11 for the O2 sensors. Once I come off of idle, the AFR goes up to ~14. Does this sound normal, or have I missed something in my setup?
I also adjusted the Barometric settings in the map to 250mv,150mb,4600mv,1060mb and now my Barometric readings match the local weather station more closely.

As an experiment, I swapped the O2 sensor wires, and started the bike. Even in Autotune, it runs really crappy, so I am thinking my original setup with left cylinder going to R12 and right cylinder to R12b must be correct.
I don't quite understand why there are now entries in the Cylofs table which prompted my experiment. I would have assumed that with an O2 sensor in each pipe, the cylinders would be individually compensated and no Cylofs value would be necessary.
On another subject, I added an led battery gauge from Custom Dynamics for ~$25.00+shipping:
http://www.customdynamics.com/LED_battery_gauge.htm#LED_Battery_Gauge_with_Remot...
I found a 6way connector in my front harness which I think is for some sort of emergency flasher which is not required in the US, and it had switched +12 and ground in it, so I hooked up the monitor there. It flashes red for voltage below 12, solid above 12.1, amber above 12.6, and green above 12.9. It flashes green if the voltage gets over 15.25 which can destroy batteries.

But the CylOffs is just that: individual cylinder mapping. Instead of actually having one InjDur table for the left cylinder and another one for the right cylinder, the CylOffs table tells you the right cylinder's deviation from the left one. So Autotune will fill it with values if necessary.

BTW, remember that whenever syncing the TB's, you should probably use a CylOffs table of all zeroes and run open loop.

And if it already did and put a CylOffs there, you will sync against that instead of getting the TB's equal.

Just to confirm, I zeroed out the Cylofs part of the map, and changed the O2 sensors setting from both to none, then I attached the CarbStix, started and warmed up the bike, and checked the TB balance at idle and ~2500 RPM. The balance wasn't perfect, but close enough so that it wasn't worth adjusting. I believe that was because I balanced the TB's before I changed the map to using the O2 sensors. I have pretty much given up on trying to get the bike to idle at 1100 RPM until it is warmed up. I use the fast idle lever to get the bike started, more or less like I did with the Marelli unit, except it works like it was supposed to now. Smiley

I don't think it's a good idea to try to balance the flap angles using the lambda probes. I'd even say that's a rather bad idea.
Or I still don't understand what you're doing resp. why you mentioned the above.
