PV support for 2012 Dyna and Softail
I was just reading about the new MT05 ECM that Harley used on 2012 Dyna and Softail models. Interestingly enough, it seems that these bikes are throttle by cable, lambda-based tune bikes. I don't think that Harley's SEPST tuner even supports them yet. But if some of you have the newer models, you would be happy to know that DynoJet is getting ready to release a PV calibration to support them.

I for one am really glad that DJ has started listening to its customers feedback. One of the things we asked for is more information about the new stuff and they responded with the updates blog. They have also incorporated a lot of features from questions or suggestions that came up on this forum.

It has been in the upper 90s to 100 degrees here is SC for quite a while. What I have done that seems to work well is this. I tuned my map with LT to get the VEs where they needed to be then went back and set the map to open loop mode by changing all the cells that were 14.6 to 13.8. This gave me a very good running map and dropped the engine and oil temps by about 15 degrees. With a little testing, I ending up changing to 14.1 AFR and found that I got pretty good gas mileage and retained the engine cooling. If you have a good tune and are still running at stoich (14.6) give that a try. Of course if you are running a Lambda tune, just replaced what I said in AFR with Lambda values.
A couple of weeks ago I did some tuning runs with the entire AFR table set to 13.0 and didn't see any noticeable change in ET during that time. I may be the exception, but this bike seems to run relatively cool regardless of the AFR thrown at it. I'd like to know if anyone else has made similar observations with their bikes.

Ok thank you I will try that and then report back in 3-4 days.

Does this refer to step 6, or something I need to do prior to logging data? Great write up!
"you must have a closed loop calibration to use Log Tuner Basic. To enable closed loop Lambda values must be between .977 and 1.02 or AFR must be 14.6."

This is in reference to the calibration (map) that is loaded in the ECM while you are creating the log file. Take a look at your starting map. In the AFR table, every cell that is set to 14.6 (or Lambda values noted above) is in closed loop. LT Basic with stock O2 sensors, can only tune closed loop areas due to the relatively small range of the narrow-band stock O2 sensors.

I do not have an oil cooler. I think the AFR change can only cool so much. I don't see any change by going lower than 14.1. Even if I change to 13.0 like you mentioned for tuning runs, the temps stay about the same as when I use 14.1 AFR.

What am I doing wrong???
I have done the data log, used log tuner to create a new tune but when I compare old tune to new tune EVERYTHING is identical....?? I am sure it is something I am not doing correctly. I should be able to aply my data log to the base map I got from fuel moto,..correct?? HELP??

Did you apply the value file back to the tune?

Log Tuner actually creates a new Value file (.pvv extension), not a tune file (.pvt extension). Once you create the Value file, you need to open the tune file it was based on in WInPV, then from the menu select Load All Values and apply that value file to the open tune. Then you should save the tune with a different name and send that back to the PV to be loaded to the ECM. I normally increment a number on the tune to keep up with versions. 001, 002, 003 etc
