JustinNck1 Posted May 31, 2015 Report Share Posted May 31, 2015 Ok guys, I think I am stumped on this Power Commander. I have uploaded and downloaded many tunes with several different power commanders, but this one is throwing me a curve. First of all, this is a Power Commander 3 USB. I downloaded the correct map from their website, and when I went to send the map, I am prompted with an error messages stating my throttle columns do not match the columns on the PC and it wants to know if I want it to adjust the columns. If I hit no, the map does not send. If I hit yes, the map is sent be modified alot and it grays out the fuel at lower rpms. This is causing the bike not to idle. Below are some screen captures of what I am trying to explain. If any can explain what is causing this, or how I can fix it, I would greatly appreciate it.

Pokey Posted June 1, 2015 Report Share Posted June 1, 2015 Looks like a PCIII to PCV map conflict? Quote Link to comment Share on other sites More sharing options...
JustinNck1 Posted June 1, 2015 Author Report Share Posted June 1, 2015 Looks like a PCIII to PCV map conflict?The map is for PCIII, so I am not 100% sure. I am gonna call Power Commander in the morning, I have read of some others saying it may be a defective PC. Quote Link to comment Share on other sites More sharing options...
vf1000ride Posted June 1, 2015 Report Share Posted June 1, 2015 What bike? They show that same greyed out map for several models when the motorcycle is still running an O2 sensor. It can't mess with the low end fuel map due to emissions restrictions and the fact that it will always be fighting the O2 sensor output to the stock ECU. If you have already performed an O2 sensor delete on your bike you should be able to get a "race" map that gives control from zero throttle all the way up.

All the tunes on Power Commander's website have values for the greyed out region, but it changes them when sent. Quote Link to comment Share on other sites More sharing options...
JustinNck1 Posted June 1, 2015 Author Report Share Posted June 1, 2015 So I talked to Power Commander, and since this is an EX model power commander, which is California legal, you cannot adjust anything in that rpm range. Quote Link to comment Share on other sites More sharing options...
Tonik Posted June 1, 2015 Report Share Posted June 1, 2015 So I talked to Power Commander, and since this is an EX model power commander, which is California legal, you cannot adjust anything in that rpm range. So edit that section of the map to be zero? Quote Link to comment Share on other sites More sharing options...
JustinNck1 Posted June 1, 2015 Author Report Share Posted June 1, 2015 So edit that section of the map to be zero?No, they said in that rpm range that is grayed out, it uses the stock ecm tune. Quote Link to comment Share on other sites More sharing options...

Does it not idle if you disconnect the PC and run stock? Quote Link to comment Share on other sites More sharing options...
JustinNck1 Posted June 1, 2015 Author Report Share Posted June 1, 2015 You said when you send the map it won't idle. Does it not idle if you disconnect the PC and run stock?From what I am told, no. The bike has a big bore kit, heads, agressive cam, open exhaust, and open air cleaner. I do not have the bike in my garage, I just offered to install some tunes for the guy. Go thing is he has a second power commander that is not an EX model, but I have to go to his place with the laptop (Older non-usb PCIII). IMO, I would have taken the bike to get dyno tuned with the amount of changes made. It's hard to find tunes with this many variables.

He did all the work himself, just ordered a 95 inch kit, heads, cam, cam plate, & oil pump. This harleys are actually pretty simple to work on Quote Link to comment Share on other sites More sharing options...
