PClll Question

I have a SERT on my bike, but I want to try different slipons on it.
Can a PClll be installed on a bike that has been tuned with a SERT?
If I understood it correctly, when my bike was dynoed with the SERT, it overwrote the Stage 1 download.
Will I have to get the Stage 1 download again if I go with the PClll?
With the help of forum members and pre mapped downloads from different sources, it would be a lot easier to tune the PClll than the SERT.

Since you have changed the baseline programming of your control module with the SERT, I would guess that the PCIII would not work correctly with the canned maps provided. I'm certainly no expert but from my understanding of how these two systems work, I would think that you should go back to the stock map so the PCIII would be working with a known starting point.

Hi SlimJim

I think you are right. I think not changing the factory computer sert the add on computer PCIII you can always go back to the old pipes and air cleaner to run standard to check the fuel mix oxygen censer and what ever they install to make it hard to work on. As time go's on there will be gas check devices for do it yourselfers like they have for cars. Later Ole School Ted

A SERT is a Screaming Eagle Race Tuner and is a unit very much like the PC3 but ties to the ECM through the serial access port. The SERT a proprietary device sold by Harley Davidson and will 'mate' to the ECM so it cannot be used on a different bike. Using both is not advisable but can be done, just twice as complex to map either one. Actually, either would work fine, just not both in the system together.

Tuning the SERT for the slip-ons is almost the same as tuning the PC3 - done with specific software in a computer. Many maps are available for both systems to compensate for the reduced restriction of slip-on mufflers.

The way I understand the SERT is that it is not a piece of hardware at all but only changes the mapping of the stock ECM. The SERT comes with a CD and an interface module that allows you to connect your PC to the ECM and contains the bike's VIN which keeps you from ever using it on another bike. The interface module does not stay on the bike during normal operation but only used when the map is changed.
The PCIII is a piece of hardware which can be programmed to modify the ECM settings and does stay on the bike. I would think that the PCIII would have to work from a known point and if the map in the ECM had been changed, the canned maps in the PCIII would not be working from where they had been designed to do.
I'm not arguing but I want to understand this also.

Im not still not sure about this. But today with out a computer The V&H componants and Fuel Pack are the only one's that can be changed back to original equipment with out a re tune or being rebooter with a computer. And what will that cost? In other words the V&H Fuel Pack is a add on that stays on that can be removed with the new pipes at home. You need to type slow In old. Thanks Ole Ted.

just what is "sert" how is is different from a pcicked:

I have a carb on mine.

I've already said more than I know. Someone who knows what they're talking about needs to take a stab at it.

One more question. Is the laptop hooked to the PCIII on the bike. Or can you load the PCIII on your home computer and then install the PCIII on the bike. Sorry im just an old gas passer. Later Ole Ted

Hi AFNurse
Thats sounds good. That way you can go back to the dealer stock if you have a serious problem that you encounter. Thanks AFNurse If you ever get to Florida look us up. Later ole Ted.
