So I'm just wondering if anyone on here is using a power commander 5 on there vtc 1800c if so, what model # is it .....I don't want to order the wrong one and how do you like it?
Okay, thank you very much.You don’t settle for ordinary performance anywhere else. Why accept that from your motorcycle? Take control of your ride with the Power Commander V fuel tuner — built to give your bike more power, optimized driveability and the fuel efficiency you need to leave routine in your dust.

The decel popping can be controlled somewhat depending which model Power Commander you have. Can you give us more detail of the model presently on your bike?I just bought an R with some sort of power Commander and I don't like it at all. I see no benefit and the deceleration popping is terrible. I will be looking to go back to stock. I would be interested in trade perhaps.
Before you remove the seat check behind the left side cover that houses the box with the tool kit. If it's a PCIII it'll most likely be there, in the box.Can you tell me where it would be situated on the bike? I'm guessing the ECM and the commander, whatever brand it is, is under the seat? I downloaded the manual but have not found it yet, I thought it would be in chapter 17 or 18. Before I hit the road in the morning I'm going to take the seat off and see if it's under there. Then I can let you know if it is. Thanks very much for the help.
I see that it is a unit you can connect your laptop to if you want to change the settings on the existing map. The USB plug is on the side of the unit. Either you or a dyno shop can do this. You and I had the same issue with decel popping that was more than just annoying and I was able to dial out the problem. Go to Powercommander's website and download their app. for PCIII. With the map up on the computer screen you will see a vertical column labeled "zero". This is part of the throttle positions where you are able to change the fueling. In this column only, starting at 1500 rpm, change the numbers in the squares up to redline (6000) to the number "30" and save the map.
Your pic #187903 is showing a red "vampire connector" in front of the large gray connector. It is attached to a wire going to the ECU. Is there another wire coming from that red connector?
Are you referring to the little red connector pointed to by the red arrow? And the ECU is the box marked with the blue X? I will look and see what I can see.Your pic #187903 is showing a red "vampire connector" in front of the large gray connector. It is attached to a wire going to the ECU.

Yup, I believe that connector was supplied by PowerCommander. If a wire "T's" off of that connector then your PC is connected to the throttle position sensor located at the throttle body. This connection has proven to be a weak link and has caused owners to experience a number of problems with the smooth running of their motor.
The cause of the problem is the TPS wire to the ECU eventually gets cut through by that red connector via bad design and vibration from the motor.
The fix is to remove the connector and hard solder the wires together. Even if you decide to remove your PC you'll still need to repair the damage done by the connector.
