It's simply a fact that a richer mixture lowers combustion chamber temperatures. The extra unburned has a cooling effect. Everyone who has gone from stock engine tune to a custom one sees temp drops.

 

I had the dealer install my PV . I want to add additional tunes , but I get 'no ECU detected'
Were do I start looking?

I'm on a 2013 FLHTCU with Big Ness A/C and Jackpot 2-1-2 headers and Jackpot 4" slip ons. Read up on the spark plugs. I think I have read that some folks have issues when changing their plugs as they are integrated with the ION Knock sensing or something along those lines.

Some of these timing areas, I just can't get the bike in to and are base numbers. I have a riding buddy who has the exact bike as me and got it tuned by a guy that used to live in AZ and moved here to Ft. Worth. I've seen his name before here and comes highly recommended. I started with his timing maps and made my AT runs. I made retard adjustments where I would ping.

I have no idea where the tuner got his timing maps from.

 

Make sure your run switch is in the run position.

 

Is the run/stop switch on run?

 

Regarding the plugs, I was hoping that Harley would sell some that wouldn't mess with the knock sensing, but were a heat range cooler, but it doesn't appear that they do. I used to work on air-cooled airplane engines, and if we got plugs back that looked like mine AND there was detonation happening, we would definitely switch to cooler plugs. A glowing hot plug can definitely lead to preignition in the conditions where I'm getting it.

I'll have to get to my other computer to compare my spark tables to yours, but yours actually look significantly more aggressive than mine, particularly in the high MAP areas. The places where I was getting the knocks most of the time, around WOT and 3500-4000rpm, my advance is only about 16 or so I think.

Yes
I plugged in , turned on . Nothing
I turn on , plug in . Nothing

I'm getting power to the PV, I get

When I download all updates, says to reboot PV, not sure how to reboot

Haa, I'm an A&P with my IA. Have worked on many pistons but my main focus is corporate aviation and all the piston stuff is helping buddies and clubs out when I have the time.


Yes, my timing is aggressive and is why my AFR probably looks different than most. I think the hottest I have seen on ET was 275 and I pulled over and added fuel to the area and was able to bring it down to 255. I had knock too when I first started with the map and it was around the 3-4000 range and about 75-90 MAP, hence the dramatic retard in those ranges.

If it were me, I would turn on logging and go make a couple runs. Some of mine where a hour before I could find just the right conditions. I also did a combination of cruise control and manual. With the log file, you will see exactly where the knock events happen, the timing range and the retard needed to correct the issue. Without the log files, you really are just getting in the range of knock. I was surprised that knock was happening in areas outside of my mental notes where I thought there happening.

When I was doing my tuning, I would take my laptop with me so that when I found a road area that caused a knock or I didn't like the acceleration up a hill, I could pull over, make adjustments and load a new tune and then run the same road a couple times.

One time, I was on highway 730 and had made 4 runs in a 5 miles stretch. Didn't notice at the time but there was a local sheriff radaring traffic. I went by him several times and he finally pulled out and pulled me over thinking I needed help or had lost something on the highway. We talked a bit about what I was doing and even made the comment that if I needed to do a WOT run that I could and he'd understand but just keep it under 100 when there was no traffic. He's a biker too. I didn't take him up on his offer.


Where are you located in Texas? If you are close, we can make a plan to meet up and make a couple of runs.

 

Are you sure that the Power Vision you have is the one that was married to the bike? Said another way, did you buy the PV brand new of off ebay or something? I'm not sure of the error you get when you try to put a PV from one bike on another bike, just know that you cannot do it unless you buy the licence for two bikes.

And, just to make sure, I'm talking about the switch on the right hand controls that need to be in the run position.

 

Brand new, install at dealer

after start up screen, there is a "?" on the on the STATUS icon, I press the status, goes to Verifying ECU communication...
