Quote from: hdmanillac on Today at 11:31:15 AMTo be honest, I don't use autotune either because it produces VE tables that are too rich in the open loop area. I use another personal technique based on narrow band probes. And this technique uses, among other things, the "Set Lambda" signal. If the signal is false, the VEs will be false.

That is why it would be interesting to collect the data with another device that will show set lambda.  This could possibly tell us if it is just a data collection problem or a calibration problem.  If another device collected it and set lambda was displayed as we think it should, based on AFR lambda table.  Ding ding.  Yes, set lambda is very important to a speed density EFI system.  The whole system is based on having this correct.  VE's are for nothing without it.

Are there two different M8 motors between touring and Softail? I thought since the M8 has a balancer it would be enough for one between the two models.

And that means minus 2 for the softails

I really haven't came to a conclusion.  This might not be a calibration problem at all.  Might be how the PV requests and gets data from the ECM.  From what I have seen and discussed with other tuners.  This has seem to be a problem in the past.  Case in point might be AE and DE traces that PV is unaware of the m8 putting out.  It would be interesting to collect data with DTT ad look at it's log.  That is how I collect data when doing a PV tune, and then I use my tune.  This has always worked out for me better than using what is supplied in the PV software.

Usually when I am collecting narrow band and there is no wide band data or a wide band controller goes off of line.  The trace reads the leanest the controller puts out.  The leanest the frt is reporting is .815 and rear is .808, but the rich's they report is .685.  But as was explained earlier by Jamie.  WB's have a range and this is reporting out of that range.

Quote from: Jamie Long on January 06, 2022, 04:18:22 PMTT uses closed loop over the entire AF/Lambda table regardless of Lambda value; closed loop will follow any commanded AF value in the calibration as long as the command is within the range the sensor can measure (.70-1.15 Lambda/ 10.5-17.0 AFR).

Seems if this bike was running as rich as indicated by the log.  Narrow band sensors should be showing the same extremely rich condition, and the trim tables should be showing it in the closed loop area.  So, I really don't know and hope they figure something out.

Can someone tell me the width of a sissy bar bottom for a 78 low rider? I'm out of town so I can't measure it myself and bored so I'm looking on the web at bike stuff.

Quote from: calif phil on Today at 07:07:58 AMLike the others said, American Elite is a great choice. 

Been running them for years. Last a little longer than the stock Dunlop's, cheaper to purchase.
Are these good on Dynas?
