In the tune created by MasterTune, the cells remained in closed loop within a square block from 30 kPa through 80 kPa axis across and 750 RPM through 4500 RPM axis down. Is this normal?

I’m going to run through the tune process again from beginning to end and see if this makes a difference. The latest manual is very detailed and this may help but, if not, my next step is to disable the EITMS and start advancing the timing in the idle stages.

Any input would be greatly appreciated.

Thanks…Larry

Yes, it should show 14.6 in the area you described on the AFR table. What did you set your Closed Loop Bias Tables at?

Went out for a warm up spin on the bike (it's about 38° F or 3° C). Blew the new V-Tune calibration into the bike. Started the bike and let idle for a while. Could never get the yellow "Waiting" to turn to Green "Good" as it shows in Doc's instructions. The AE, DE, AFR, ET, and MAP all turned green, but the "Waiting" would never turn. I tried gathering data anyway figuring maybe it would?? It never worked. Rode around for a good 30 minutes (after blowing the new calibration in...total time running was probably closer to an hour).

Here''s a screen shot after trying to gather some data:



Any suggestions? Any ideas what I might be doing wrong?

Steve - You are always saying you take suggestions into consideration...here's a couple thoughts...Within VTune pages, let users keep the type of bike selected from tuning session to tuning session. Maybe like the Save Display Assignments Now option in the main section of DataMaster? Minor nuisance to have to select Sportster every time I bring the VTune page up. Another thought, can we view the temps in Celsius? Why would I care what they are in Fahrenheit when all the tables are in Celsius? My thoughts for now.
