So I finally got me a PC-V powercommander.
I need to remove SERT module and plug the factory setting in.
Where is it located? In the EFI?

Fat Boy 2006.

 

The SERT is a separate unit that is not attached to your bike. You are going to have some issues with the PC if you don't know what map has been installed on your ECM.

 

Hmmm. But I got a separate black little electronic box that is supposed to contain the factory settings.
Wait.. taking pictures..

 

The race tuner (SERT - Screamin' Eagle Race Tuner) is not a module that piggybacks on your Electronic Control Unit (ECU). It is used to tune your existing ECU. It connects between a computer and your ECU and allows the dyno tuner to make the required changes (program) to your ECU. To use the Power Commander you will need to have your ECU reprogrammed back to the stock map by a tuner of your choice using your SERT unit.

 

Now. This is what it looks like.
Partnr: 32957-04A
Screaming Eagle performance software.

Must be stuff I got in my bike now, as I got SE airfilter and pipes.
So how does it work?

I guess the salesrep was missinformed when he told me that in order to restore factorysettings I just plug this thing in.
But I assume that this thing contains the upgrade that the tunerguy download to the EFI
Correct?

 

Ok. This is what I found out so far.
My bike has the Stage 1 1450 EFI kit.
According to some the only thing this does is to raise the revlimiter.

Someone on another forum was told by the powercommander people that this should not mess with the PCV.

That could explain why my fat boy is running very hot and lean.

Shall i take the plunge and try a map? If everything goes to hell I could allways download a "0" map and call a tuner.

I´m not to keen to dynotune the bike right now as I am having a 1550 highcompression 10,5:1, Andrewscams and porting done in a couple of months.

Thanks for your advice.

 

The shop that will be performing your dyno tune will have to be knowledgeable about Power Commanders and Harley's ECU. My advice to you is to ask whoever is tuning your motor. Who better to understand how to integrate the PC with your new setup?

 

Ofcourse. But I plan to save 400 dollars and wait with the dynotune and go ahead and choose a map from the Powercommander site that is closest to my setup.
Otherwise I have to make two dynotunes and that means less beer for me.

 

RENBACK, gonna try to save you some trouble down the road.....dont go with the 10,5:1 set-up. you'll be fighting PING big time. unless your planning on a bunch of other stuff. bigtime tuning, (retarding timing) either via controller or 4* gear. better get comp. releases while your getting the heads done. and if you decide to skip the releases, you'll be in the market for a starter. go with a nice flat-top build and not too much comp. you'll be better off and much happier in the long haul. steve

 

Based on some replies I might be in trouble when I put on a new tuner. The bike I purchased was tuned with the SERT but the previous owner did not get the cables or black box back in return. So if I read the posts correctly I'm in trouble when I go to purchase a pwer commander or other tuner.
