After the cams, I would do 2 or 3 runs to get the VE's somewhat close first. Then have a look at your graph. Then, if you feel the need to mess with the CDE's do it after each run. If you've messed with the EGR before you already know it can be frustrating due to how the changes affect other cells and diminishes. I wouldn't mess with the timing during this part of tuning if it isn't pinging. If it is pinging work the table before you go back out.

The 255's will bump your compression a bit so it may ping more after they're installed. Just something you want to have a look at after your first tuning run. I used a map from FM for the 255's in mine and the timing was pretty conservative so I don't think you'll have any issues. But I'd have a look anyway.

 

What is the procedure for powering up the PV while not hooked to the bike? Using the software there is a way but can't find it anywhere.

 

The map I presently have used the FM Stage I map as the base. The timing table are the same in the FM Stage I and II maps. I will be incorporating many of these suggestions in my next tuning sessions.

Thanks all.

 

Plug the PV into your PC and open WinPV. Then at the top menu bar go to PowerVision/Diagnostic Test Functions/Exit PC Link Mode. This will let you view a some things in the PV, but not all.

 

when i look at a pvv log for spark i see positive and negative numbers as well as a few zeros

do the zeros mean no change, positive numbers represent advance and negative numbers represent timing pulled ?

 

Autotune problem. Every time I try to flash an autotuned file, I get "ecm error".

 

Is your run switch in the on position?

 

The ignition must be in the on position not accessory and the kill switch has to be in the on position also

 

Hi guys, this might be a dumb/lazy question but is there a quick link to the latest autotune documentation and firmware? I havent done mine since autotune was just in beta.

I searched through the thread but with over 400 pages I couldnt find the current info.

thanks in advance

So I got a note from Jamie at FM a week or so back and he said we needed to address my map after the Dynojet rep made some changes via remote PC link. I don't know what needed to be address and I have not heard back from him yet either.

I did some data logs and I still have some knock events, but I don't hear any pinging. Most of the knock events are 2* or less on the front cylinder only in the 60 kpa column from 1750 to 2750 rpm. I had one 7* pull, but it was getting pretty warm in stop and go when that happened so I think that was just an anomaly.

Question is, what is considered a minor knock event and what is considered a major knock event? What should I ignore and what should I worry about trying to fix? I have done auto tunes and I have done Log Tuner tunes. Both say my VE's are no more that 2-3 off so the VE's are dialed in and when using Log Tuner it doesn't ever want to pull more that point 2 or point 3 degrees of timing in a few places.

I have created several new tunes using the Lot Tuner allowing it to pull those small amounts of timing, but I still keep getting the knock events in the same places. I even allowed it to readjust the VE tables in the last two Log Tuner maps, but no real change in knock events and again the VE table changes were less than the 5%.
