I am close to bottoming out on the infamous stage 1 upgrade. I already have the SE intake, not installed, and plan on getting VH BSS pipes. So far I am leaning on the PCIII for EFI tuner. Anyway I am curious how well they hold up to the heat which is the arch enemy of electronics. Here iin AZ the temps can get a little toasty. I sometimes ride it to work in the 110 degree heat. It is a rather short commute so not too painful. I am just wondering how the PCIII holds up to extreme heat.

Thanks for any info.

 

I live in California, hot summers, and have ridden to and in the Phoenix area in the summertime, on numerous occasions. Last time I was there, we rode to the Grand Canyon from Phoenix in 113 degree temps. I've had a PCIII on my '03 heritage for 4years and have over 50K miles on it without any failure or problems.

 

Put 42,000 miles on my 06 Ultra in Florida with my PCIII with no problem. Just bought a 09 Ultra and will be trying the new Super Tuner. I hope I like it as well as I did the PCIII. There are some GREAT MAPS out there for the PCIII. Cooled my bike down and really increased the tourque.

 

Thanks for the info.

 

No problems yet. I have had it on since May, but I live in Illinois. Hot but not that hot.
