I got one of the first Procoms when they first came out a couple years ago and installed in on my 06 790cc America. The results were awesome with the recommended settings and one of the few maps available at that time.
Then it started dying at stops and difficult cold starting. Eventually I returned it to Procom who promptly replaced it, I paid the shipping one way.
The replacement didn't seem as well put together as the original and displayed similar operating characteristics to the first one using the recommended settings.
At one point I had both the OEM and the Procom mounted under my tank and could switch the wiring harness between the two. The last time I tried to use it, it acted as though it was intermittently switching between 270 and 360 degree mode. I went less than a mile and switched back to my OEM CDI.
Later, after removing the Procom completely I hooked it up again trying different settings and apparently decided on #5 but I remember just starting the bike and letting it idle to see how long it would idle before shutting down. At first it was a couple minutes but finally it was less than 30 seconds so I concluded that there must be a heat problem and was thinking about a heat sink configuration but that was well over a year ago.
Since then I haven't put much time in working on the bike but more in riding. Also, I've thought about possibly there might be some low voltage issues the Procom is more sensitive to than the OEM after reading the threads about low voltage issues with our bikes but haven't followed through on that either.
Since reading CHY's post on the other thread about the gas pump incident and his revisiting his procom issue which seem to be common issues, I pulled mine off the shelf just to see what the last setting I used which was #5. The label on the back of the unit indicated that numbers 8, 9, and 0 are reserved for factory stuff so I never tried those.
I guess if I have a question in all this it would be, has the factory made some changes in the last couple years making #8 openly available on newer modules or do they still list #8 as a factory port? If not, I'll tinker with mine again and see if I can get it to function using the CHY technique plus I'll verify my voltage at the module. I would really like to get the thing working. I love the performance increases when it all gee haws just right. But even though I enjoy tinkering, I would rather be riding so I need something that is gonna stay the course for the long haul.
I'm not running down Procom. I'm grateful that somebody finally offered us an alternative to the OEM and the rev limits that shut us down just when its gettin good. But I also understand that when the tech is new there are bugs to be worked out. Its been a learning experience for me and there are factors I didn't previously consider mainly due to limitations in time and a greater desire to ride than to tinker. Sounds like from this thread that Procom has been working with most everyone and what issues arise have been easily resolved or maybe just lived with but thanks to CHy's gas pump incident I'm encouraged to give mine another go.
