Im about to start digging into the other promm to see if it stores a 2nd set of tables. Once done I should have an exact map of all tables including lookup and reference tables as well as be able to remove the 40+ dummy tables in the database. Perhaps if I can get this one done I will be able to do others and take the mystery out of the Harley ECU/ECM

I just put a powercommander on my 07 1200N, and im having a problem with it cutting out at idle it seems to be struggling for air at part throttle. I have hooker reble drag pipes and a xl windforce intake. powercommander told me to run the map for vans and hines shortshots and a screamin eagle stage 1. Any help would be greatly appricated.

i have found that if you increase the numbers in the 0% throttle position colume the tickover will raise and if you decrease them the idle drops i can get my sportie to idle at 800 rpm but i get decel popping because the mixture is lean, so what i did was increase the number until the bike would idle (at normal running temp) and played with the numbers in that colume rather like you would with the idle jet on a carb, i raised the numbers up through the point that it ran smoothest till it stumbled with an overly rich mixrture and then back to the sweet spot. go up and dowm 5 at a time ie if you are at 5 try 10 etc. the sweet spot shoul have you idleing at around 1050rpm

If you like, you can now transfer the values from the 07 SERT timing table shown below directly to your SERT programming and see how your bike responds. I believe you will be very happy with the results.

BTW ... We are using the same data shown below for both the front and rear cylinders, so apply this same data for both cylinders.

Enjoy,

Here is the timing table as applied to the 07 SERT:

And here is what the above timing table looks like in 3D Graph form:

This is an awesome map but I've lost mine (computer crash). Can someone re-post the map or PM me the map? Thanks.

I recently converted my 2007 883L Sportster to Stage 1. Since my bike already had RUSH Slip-Ons on it, I installed an Arlen Ness Big Sucker steel jacketed breather, and installed a Power Commander 3 USB. I hooked my sporty up to my laptop and downloaded a map that was similar to it. I wanted to know if anyone else has used the Power Commander, or has any tips or suggestions on the correct map to use? It seems that the only breather used in all the downloaded maps are for the Screamin Eagle, and my RUSH Slip-Ons aren't in there either. I am currently running with a map that lists the Screamin Eagle Breather, and Vance and Hines Slip-Ons.

I have a custom tuned map for the PC3 rush slipons and SE filter if your interested shoot me a PM and I will send it over. Its worked well for me. This is from a 1200r 08 It sucks gas but youl get a great deal more top-end as rev limiter is removed, it pulls well in the 3-4 k range.
