Before you ask, it seems that the 1690 upgrade is now tied up with HD management and the dealer owners since the customer still doesn't have their bike back. There are STILL HD factory isssues with the 06 maps, 06 stock ECM and the 06 SERT software.

I mentioned to my guys your suggestions and that they could reprograme the ECM serial number using the Scanalizer ---something that they hadn't experienced yet.

In any event, a couple of the Techs went to Sturgis to help tune and repair bikes during the event (free room and board and eats with some money too) In any event, they said that they had an inordinate number of bike that had the SET installed and wre not running very well at all up in the hills. After loading down a CARTRIDGE up grade the bikes seems to run MUCH better. This was also the case with the Power Commander bikes too.

Many of the SERT owners forgot to bring their inline security connectors and software so they were screwed somewhat.

MY QUESTION: In your experience--Are the SERT and the Powercommander not able to adjust themselves to climate air and temperature changes as well as a cartridge?? I was under the impression that the code was the same and that the downloading and tuning was the difference.

(We ran into this issue down here in Florida a couple of years ago during Daytona Bike Week when it was so cold and dry up north and those bikes wouldn't run in the heat and humidity).

REGARDS

First I must remind you that I am far from an expert on the SERT and EFI systems in general. I have a basic understanding of how it all works but not a specific understanding of all the parts in the systems.

With that said, some of the terms I used may relate to a car EFI system more than the HD system. In the initial post I stated that the MAP sensor was a Mass Air Pressure sensor and over the weekend, while wiring a MAP sensor on a bike the instructions called it a Manifold Air Pressure sensor. I have always heard of it reffered to as a Mass Air Pressure sensor in the automotive field (right or wrong). UPDATE, informed it is "Manifold Absolute Pressure"

How does this help with your question? I would think the MAP sensor would compensate for the altitude since altitude effects the amount of air pressure. But not being a closed loop system (O2 sensor), I am not sure how it would effect it. Maybe Grock will read this and set us both straight, as I understand he is the man when it comes to fuel injection.

Scanalizer is not the tool used to set the VIN number, I believe it is called the Digital Tech or something like that. My understanding is that the scanalizer only reads the codes from the ECM??

The Flash loaded into the bike is just a default MAP for the ECM that works with a certain combination of parts, like a stage 1 for example. I don't believe there would be any reason that using a SERT to create a MAP for the ECM would be any different than a Flash.
