Had my flash done yesterday. Told the service mgr there was a PCIII on the bike. He said it didn't matter. Bike runs fine ... I don't notice any difference.

 

That is just sad. I bought an 06 with 3 miles on it and am having a blast!. These bikes are for riding. Forget waiting. I wanna ride!!!!!!!!!![8D]

 

Riding up to Battlefield H-D this Saturday for the ECM flash and then a dyno tune. The service guy knew nothing about the recall. I explained what I have learned on this forum and provided the recall #. He found it after searching for about 5 minutes.

After I heard him snicker I asked what was so funny. He replyed in so many words that folks have complained about what this recall fixes and Harley has claimed no problem.

By the way if anyone is in the Gettysburg Pennsylvania area on Saturday (12/2) let me know. Maybe we can meet up at Battlefield H-D.

 

And FWIW, Yes, I was a bit presumptious on my statement about the PC preventing comm..... So I did a little experiment over the past 3 days....

I hooked up 19 different bikes, all equipped with PC's (III, IIIr, III USB).......

Out of those 19, 1 had no comm with PART of the data that is transmitted from the ECM to the D/T...., 3 completely failed comm

After finding those 4, I swapped them to other bikes, to see if it was the bike or the PC.....

Found that out of those 4, 3 had outdated FIRMWARE (Internal Logic programming), and 1 had an internal short (The back plate was severed off 3 of them, and the zip ties were holding everything together)......

The reason for the outdated firmware was these units sat on a shelf for over 3 years, and technology passed them by... They would hold a tune, but the LOGIC that it uses to manipulate the data was outdated....

As far as the case cracking and back plate detatching, that is an installation problem.....

12 of 19 were installed by the customers, the 4 that were bad were in that batch of 12......

If you do have a PC mounted on your bike, I would suggest INSULATING the PC from the vibration of the bike by using some Camper tape or doublesided foam stripping to absorb the high frequencies that occur to the chassis.... I think that this is what is causing the internal shortings, as the guts are solid state, but with time and constant vibration, ANYTHING can and will break/fracture.....

The PC is a decent unit, and I am not Biased against it, if anything, Dyno Tuners who are looking at making a quick $$$ would prefer to use it, as you can tune on the fly. and you have less areas to work with... Cheap and quick.. NEXT.....

I have seen far too many of them fail (Prior to this "Experiment"), to see some flaws that are in them..... My first PC was a III.... Would engage and manipulate fuel/spark mods ONLY when the ambient Air was at least 50 degrees..... Lasted 4 months.. Went to a IIIr.... Better unit as far as wiring and construction, same tuneability functions, but at least is was engaged at all times..... With the USB variant, you now have a few new features (Rev Extend/Accel Pump).......

 

shovelhead,
Thanks for the recommendation to insulate the PCIII from chassis vibration. I will do just that.

How many of those 19 were the PCII usb versions? Just curious.

 

I've got an 06 FLTRI. I've had the surge problem since day one (Dec 17, 2005 build date, March 2006 delivery of '06 model year). I gave it a 1000 miles to see if it was break-in related. After the oil change and general check, it was still there. I fussed about it to my local dealer and it was brushed off. Took it in for the 10,000 mile check and made a issue out of it. The dealer said that perhaps the EFI was miss programmed (?) and did another download. I could not get a straight answer regarding EXACTLY what the download was intended to correct. The service ticket explained that the service manager himself rode the machine and everything, including engine deceleration performance was normal. Balderdash! The surge is still there and a recent conversation revealed that I apparently "may not be downshifting correctly." Oh, please, spare me! I've been riding too long for this.

I guess I'll be bugging the dealer some more over this. Perhaps another mysterious download will smooth out the surge?

 

3 were USB, 1 was IIIr.......

PC II/III are non players as they are only found on MM systems and do not allow any comm or data streaming....

Really old technology....

 

Welcome to the forum! Alot more action here than what we are used to.

Unfortunately for your situation the 2007's are the only bikes that H-D has admitted to having a widespread surging issue.

Should have went to Gettysburg with me...they would have hooked you up somehow!

 

06's had an issue that required the injectors to be redesigned. I think they went from 8 degree to 25 degree spray angle and that cured early 06 problems. If you have the early injectors keep complaining till the replace them.

 

25 degree injectors didn't cure anything on my 06. It still surges. I had to put on a revtech dfo to cure the stalling, coughing and spitting, not to mention the heat and pinging.
