Yeah, the info out ther about closed loop bias voltage seems to differ slightly.....Here is some more info that states something different about voltage. It says 500mv translates to 14.6:1 and that 700mv would be closer to 14.3:1.

Anyway, the bike is running well thanks to all the info and help here. :-)

 

OK, so you have a tuning version and a riding version which are versions of the same base map. One has AFR and switches set for tuning and the other set for normal riding - Yes applying the changes to both of those map is fine. Actually that is what I do if I am only making 1 set of changes.

 

"Pro level" just refers to the tables that are available for display and adjustment in the WinPV software. Go to Setup > Options and change your User Level to "Pro". You don't have to have wideband sensors to use pro level functions in WinPV. Everyone should set the software to pro level

 

I'm curious. Are you still running a closed-loop map (AFR at 14.6) and reaching these temps? If so, change those closed-loop AFR cells from 14.6 to 13.8 and test again. Iclick reports he doesn't see any difference but I run open loop on my bike and it runs about 15 degrees cooler.

 

450mv would translate to 14.68 AFR or 1.00 Lamba, 730mv would translate to 14.62 AFR or .996 Lamba. The bias is a way to slightly offset the entire AFR table. Changing from 450mv to 730mv would give you an offset of .06 AFR richer on all your AFRs. The stock O2 sensors have a narrow bandwidth so you shouldn't go much more than that.

 

Thanks JD. I am running closed loop from low RPM through 3500 and up to but not including 70 MAP, with a Lambda of 0.981, as I recall. I think this equals 14.32 AFR. I used a base map for my set-up from FM, but after tuning (in Basic Mode) I did not change any of the AFR's. I will lower the lambda to 0.945 (13.8 AFR) and give it a go. Thanks for the advice. I'll let you know how it works out.

Thanks, Lonewolf, for the perspective. I am going to lower my Lambda and watch KR very closely for specific problem spots. Will report back.

I'm sorry, you are right. I was mixing it up in my head with the CAN tuning. The Dyna's didn't switch to CAN until 2012.

 

Now I'm really confused. Your '09 has a CLB table? I thought only cable bikes ('07) and only a few '08 calibrations had one and all others were adjustable by changing the Lambda value between .98 and 1.02. Can anyone clear this up?

 

I would let the PV tune-out the detonation, but be wary of false knock events reported by the ECM. Mine does this at one point on the front cylinder only and will show knock regardless of the amount of advance you put in. If it keeps pulling out spark advance at the same amount on a sporadic basis I would put the old values in and just let the knock sensor deal with it in its own way.

In my case it will retard usually not more than 2° for a few seconds at the same point on the graph (~60KPA @ 2200-2500 RPM) but only sporadically, then will revert to normal. I haven't seen any PE spark adjustments come from this odd behavior, but Jamie told me to just leave it alone and don't let the LT tune spark-advance in that area. I now feel like spark-advance is okay and I no longer move the spark tables over to WinPV in the last step of the tuning process.
