The table only has RPM fields up to 3000 rpm.

My understanding is that these offsets only affect fields set at 14.6 (closed Loop mode)?

They affect fields above 3000 rpm in closed Loop mode?

Do they affect fields above 3000 rpm in open loop more (ie; AFR set at 13.5 for example)?

thanks, jb

The ECM uses the last know value so if the table stops at 3000 and your at 3500 in closed loop it uses the value from the 3000 point. HD does things in a strange way in that they apply the stored changes all the time, open or closed loop doesn't matter.

Steve,

Let me make sure I've got it...

So, If all my CLB tables are set at 781; then the areas where I have 14.6 will all run about 14.43 in closed loop?

And, if all are set at 781; then areas of the AFR where I have 14.0 will actually run about 13.8 in open loop?

thanks, jb

That is how it will work provided you calibrated the VE tables using Vtune and you gathered enough data to turn the cells green prior to stopping. Once the system has corrected the VE's for the setting you have in the CLB table there will always be the offset you created between the AFR table number and the CLB number. Now if you did not calibrate the VE's to the CLB values no telling what you will get.

Thanks Steve.

I had actually VTuned with CLB of 684 and it runs great. Although the motor runs a lot smoother and cooler, I want to rerun VTune with 781 CLBs to see if it adds any more power and/or cooling over the first tune. Right from the dealer (before using VTune) the 103 stage II had oil temps well over 300 at shutdown. Now it doesn't get above 258 oil temp at shutdown on a warmer day (same distance). I'd like to see it just a little cooler if possible.

We ran the v-tune 4 times the other day to get good data.
Ended up with a pretty good running bike.
Oil temps checked today: air temp:90 degrees, Key West; slow and go traffic. 230-238 on my oil temp dipstick.
Mileage=43-48, 2 up, 45-65 mph. Got 35-38 mpg at 70mph towing the trailer, still not too bad.
offset bias at 762 across the board. (14.53? AFR)
Bias was set at 801 prior to the v-tune, still ran pretty good, but, I didn't have the VE's to go by.
I'm not 100% satisified with my TBW settings, I may have to play with that a little.
So far, I'm pretty happy with the tune, starts every time, runs great, no unexpected issues with driveability.
Gotta thank Doc for all his help getting me to this point.

The richer you run the cooler to a point it will get as well as lose some mileage. So its a trade off. If you play with the CLB table and lean it out some when above 2000 and richen it down low say at 1000 you may find it is cooler at low speeds of stop and go yet save some of the mileage.

I think I may be pretty close, I have the ETMS on, and have not heard it activate yet. Before the Mastertune install, it came on all the time, in cooler weather! Best of all, the bike does not fry my wife's leg!

I'm just reading all of these posts to learn before I start tuning my bike but I'm already feeling the heat from my CC on my foot and it's still pretty cool here (mid 60's)--so the CC's got to go and I've got to learn enough to start tuning!!

I'm too impatient to read all the instructions to do it all myself, but, I have found some nice people way smarter than me to help me through the rough spots.
With the proper parts, and help from people on this forum, you will learn that there IS hope for the '09's!
They CAN perform quite well, and not cook your leg!
When mine was new, I had to take the lowers off at temps over 80! NOW, I can ride the bike with them on; had 90 degree weather yesterday, and 90% humidity, and stop and go traffic.......wife did NOT complain of excessive heat (my indicator!) LOL

Sorry to resurrect an old thread, but should Vtune data be collected with the CLB you plan to run or with CLB closer to stoichiometric?  I assumed putting the CLBs near 450mV would make the VE generation process more accurate since the 02 sensors are most sensitive there.  After tuning, I put the CLBs where I wanted them (720mV).  Do I need to retune at 720mV?

[GtreetSlide]

VTune will set the VEs based on your CLB table. If you change CLBs, you will need to redo Vtune.

Thanks, guess I over-thought the problem.

[bob2002]

My tuner,Dave of JD'S CYCLE WORKS said the CLB can be changed if the VE is correct without having to V-TUNE again.

[GtreetSlide]

I would check with Steve Cole on that, but I do not think it is correct.
