PC III problems at altitude
I just got off the phone with two dyno guys here in the rocky mtn region. They both are PC tuning centers. Both told me the same thing that they would not put a piggyback (ie PCIII) on a Harley here in Colorado. They both said that you can set the custom map right on and then with the constant baro. pressure changes, and altitude differences that the bike will run different. Anyone have issues with this. The one said he sat several up and sea level, and lower elavations and never had issues. But when he moved his shop to Colorado he had several go out with good dyno readings, and then the weather would change and the customers were not happy. They both recommended the SERT, or other "direct" link software to reprogram the ECM. They both said they would go ahead and dyno the bike with the PCIII but just wanted me to know about the issues. So now I am thinking about dumping the PCIII and going SERT, or the one said he had software that would allow him to modify the stock ecm and program it for my setup. Needing a little help here.

Well, since the PCIII adds or subtracts set amounts of fuel AND the sensors on the ECM still make minor adjustments for altitude, it doesn't make sense to me UNLESS it is something to do with disconnecting the sensors (O2 ) on the 07s and 08s. Does the ecm on the 96 inch motors still have all the sensors the 88s do other than the O2 sensors or do they eliminate the need for some that were present on earlier, open loop models?
Also, under drastic altitude changes, you could temporarily add fuel (or subtract) in areas via the buttons.
