Power Commander V Question

[fammdw]

Can someone tell me the difference between a Power Commander V and a Power Commander V EX?

I purchased (it's on the way from UPS) a PCV from a member on another forum that had it on a Vaquero he is now selling. When he told me it didn't have the two wires that plug into the ECU I was confused as to whether it was the correct one for my bike.

When I check Dynojet's website it states the correct device for a 2012 Voyager is the Power Commander V EX. It doesn't list the Power Commander V.

I figured someone on here might have one connected that could answer this question.

Thanks,
Mike

Sorry, did not mean to give incorrect info. Went back to the PC site & found the PC5 in addition to the EX.

I'm planning on one sometime this spring for my 1700 Nomad.

The Power Commander PCV IS available 3 different models.

#1...the basic PCV which ONLY allows for air/fuel mixture changes but allows those changes over the entire rpm and throttle position range.

#2...the PCV with "ignition timing capable" adds to the basic PCV the ability to alter ignition timing in the same manner, that is over the entire rpm and throttle position range. This is the best and most comprehensive model as it includes the ability to fine tune the air/fuel ratio and alter ignition timing.

#3...the "EX" model which was developed to be EPA legal. This unit DOES NOT ALLOW any fuel adjustments in the rpm and throttle position areas where the emmission testing is done. This unit is NOT the best as it DOES NOT allow full and complete tuning, it was designed for California residents to have the ability to tune their skoots but also meets CARB's (California's EPA) requirements that an aftermarket part cannot increase the emmissions of a vehicle.

The 2 wires you refer to are the wires on the "ignition timing capable" PCV that are connected into the Vulcans ignition that enables ignition timing alterations. Sounds like you are getting the basic PCV, just make sure it does not have "EX" on the face.

HOPE THIS HELPS

Ray:

This unit does not have EX on the face.

The reason I was confused is because if you go to Dynojet's website and look at the install directions for the Power Commander V and the Power Commander V EX, they both show the two wire connection from the unit to the ECU harness. This particular unit does not have those two wires. Just the grey wire that connects to the harness in the TPS servo motor and of course the injector plugs and ground.

I asked the guy I'm buying it from and he said the unit was purchased in 2011 and has since been replaced with the version with the two wires that connect to the ECU. He stated that Dynojet added these two wires on the current models to give the unit a more accurate reading of the RPM range.

Based on your experience, will I be okay with the unit that does not splice into the ECU harness?

Thanks!

Mike

Here's the unit:

YEP... you will have no problems with the older unit, that's the unit i had b4 i upgraded to the unit with ignition timing adjustability.

I purchased it because I've read on here that you can eliminate the decel popping with the unit. Mine is very minor right now after following the forum advice on marbling the fresh air intake. I understand a fuel processor is also needed if you change the stock air box as well.

For right now, I plan to just switch out the air filter for a K&N filter. Do you are anyone else on here have a custom map for a VN1700 running Vance & Hines slip-ons and a K&N filter in the stock air box?

This is uncharted territory for me as I've never did these mods on any other bike I've owned. All the others have just had pipes alone.

Thanks!

Sounds like Ray has you covered. You have the one without the Ignition Advance, still a good unit though. The the 2 wires you spoke of hook to the ECU Crank Position sensor pins.

Thanks for chiming in RWB! I feel better about it now. I paid $175 for it which I thought was a pretty good deal. New one's are north of $300 and would not fit in my budget right now.

I'd still like to hear from someone on a map for the V&H pipes, with K&N filter in the stock air box. If anyone has a good map for the same set-up with Chucksters air kit, I would appreciate it as well. That's most likely my next purchase when I squirrel away a few more pictures of dead Presidents.

Installed the PCV today. It still had a map in it that the guy it came from ran on his Vaquero. When I went for a ride, it was really quick in the upper range of the RPM, but sputtered a little when starting from a stop and turning slow in second gear.

I hooked up my computer and changed the map over to Dynojet's map for my bike with V&H pipes and a stock air box. It wasn't quite as strong in the upper RPM range, but ran much smoother over-all. Hardly any decel popping now.

Can someone tell me if I'll need a new map if I just swap out the stock air filter with a K&N filter using the stock air box? I wouldn't think so, but don't know for sure. It should be getting quite a bit more air just changing the filter.

Thanks for the info!

The filter you speak of, I would not think it warrants a new map. Now if you bought a big air kit (which some come with round K&N) then you would.
