Neither has any functionality for modifying timing.
Basically, the PC5/6 are only piggy back tuners for fueling.

That is flat out incorrect.

Quoted from DJ website directly "All PC6 models have an end-user adjustment of +/-15 in the FUEL table and +/- 8 in the timing table" plus I have 'years' of experience using these products to tune everything from crotch rocket street bikes to ATV's to turbocharged RZR's.

OK.... inquiring minds want to know, how does the whole WATER intrusion situation work when we "Open Up the Air Box"?

I know we need to get MORE AIR into the AIR PUMP (engine) to help it reach optimum performance. In following the Forum, I've seen 2 common ways to do this. They are as follows:

1.) Snorkel Removal

2.) Make Holes in the Air Box/Air Box Lid


My questions are:

1.) How does this handle WATER if you get stuck riding in HEAVY RAIN?

2.) How does it handle WATER if you get stuck crossing a Stream/River/BIG PUDDLE.... ???


I spent a bit of time on ATV's while by Daughter was growing up. I've had my Honda Rubicon go through water so deep, only the top of the Seat & up were sticking out of the water. It didn't miss a beat!!! If you EVER want a "TRACTOR" of an ATV, that's one of them! My worry is if we remove the "protection" the incoming Air has, will water go into the engine and HYDRO-LOCK! Bending Engine Parts is BAD!

What are the odds of this happening if mod #1? Mod #2? Both?

Thoughts? Comments? Concerns?

@MN Willie There's nothing wrong with simply 'adding' the Dynojet o2 bung to the existing headpipe and leaving the factory o2 in place. Simply mount the new sensor upstream a couple few inches and clock it at a 45deg angle from the 12oclock position. If you ever decide to remove the autotune sensor the port can be plugged with a proper o2 bung plug. Most reputable auto parts sources sell them such as Summit Racing. If I remember correctly the Dynojet PC3/5 weld-in bung includes a threaded plug.

Did you read this MN Willie? You CAN advance timing for 91 octane fuel. This is where you can get a bit more power than just adding fuel along with open intake and exhaust.

Is this indicative of timing advance capability?

Look over on the left hand section of the screen within the box that has the drop down menus under the PC logo. The bottom two boxes are "fuel" and just below that is "timing". Take your mouse and click the white box next to where it says timing. This brings up the 'map tables' for the timing curve, it looks just like a fuel table with X and Y axis. One can then start inputting figures in these fields for the amount of advance or retard that is desired.

The area you have circled is simply the field where one can view the amount of adjustment happening in real time while the computer is hooked up to the bike. Same goes for the other parameters such as fuel, RPM ect.

THANK YOU Briggs!!!!

I have ordered a Second Exhaust Head Pipe from a low mileage 2022 KLR that was totaled. My plan was to install the new Bung in that Pipe so I can retain my original "JUST IN CASE". AND.... IF I screw up the second Pipe "playing with it", I once again have the original to toss back in to get back up an running in short order.

Given this 411, are you still thinking the SAME LOCATION & ORIENTATION for the "second" Pipe and the NEW Bung placement?

All this Injection stuff is still newer to me too. My FLHX was my 1st, and I had the BEST local help on that project! Still a learning curve for this OLD Carb Boy!

Thanks again,

Willie

The ideal position for the bung is at 12oclock.

Sometimes it's necessary to mount said sensor in a different orientation, 45deg is preferred in such cases. In a dual sensor setup the canted position allows both sensors to receive a steady(undisturbed) supply of exhaust gases without causing too much restriction/boundary layer which can result in "less accurate readings".

The Man in the Brown Truck just stopped by!!!

So.... If I'm hearing you right, grind my "old Bung" out (ouch) and install the new Bung (Dyno Jet Supplied in the Auto Tune Kit) where the original Kawasaki Bung was located? This will be the "OPTIMUM" location for this "application"?

THANK YOU once again!

Just don't do it like this! Lol
Preheat the Bung so you don't blow through the thin head pipe. Or have a pro tig weld it for you.

You forgot the "Where Applicable" at the end of that quote about timing control because that's not entirely accurate....but anyway...

Sorry, I don't have any specific experience on the PC6 for the KLR.
Specifically, I've been around the PC5 on the yamaha cp3 platform long enough to be familiar with it, and the cb1100 platforms only for a short time, but have done a good amount....sorry no generalized "crotch rocket street bikes", "atv's" or "turbocharged rzr's"....for whatever that means... The PC5/6 specifically on the Yamaha CP3 platforms simply do not have the ability due to their physical connection only between the 3 injectors, TB and O2. there is no way it could adjust timing on the pc5/6 on those machines...physically impossible. The cb1100 is piggy backed at the wiring harness and "could" have the functionality, but no timing functionality is offered for the 5/6. Fuel only... Again, this is more on a specific platform, as most have moved to flash tuning due to the additional capabilities vs. the new limitations of the pc6 in general for more in depth builds. Basically, your not using a pc5/6 for any real radical builds, but it is good for simple bolt on's like intakes, exhausts, etc. This is where it may be a very good tuner for the KLR.

It's great that you have "years of experience using these products to tune everything".....Good for you!! I honestly hope you have chosen better tuning hardware for anything beyond bolt on's though....but you be you!!

Hey Willie,
Any reason you wouldn't leave the OEM bung alone and simply install the additional in "generally" the same location, but rotated? This would also give you the opportunity to install a stand alone AFR meter if you wanted, once your done.

Yes sir! Just double check to see if it's active and you can click on it and make changes. What platform is that? That would be great if available on the PC for the gen3.

Many of the pc5's look like this. This is a quickie off my cb1100 garage computer. Notice it doesn't have the "ignition" tab on the left side....

HI Drew!

THANK YOU for your reply!


This is from the Dyno Jet Website under the PC6 page for the KLR650 Q & A:

Can the AFR be adjusted at all rpm’s, or are there sections of the power curve (sections of the map) that cannot be adjusted on the 2022 KLR Adventure ABS? Also, can the PC6 advance timing on this bike?

Question by: Mark Burge on Feb 24, 2023, 5:02:44 PM

Hello Mark,
The Power Commander 6 allows you to adjust fuel +/- 15 throughout the fuel table and in this case timing as well. For further questions please reach us directly at [email protected]

[DrewNJ]

That is fantastic! I'm really curious to see what the auto tune does, specifically with the timing. 8 degree potential, cool!

Anyone ever play with timing on this platform gen 1, 2 or 3? Are they manually adjustable? The reason I ask is on the Kawasaki 250/300X Jetskis they have a little finned timing rotor and pickup on the front of the motor. It was a common, yet backyard, mod to notch the rotor to rotate it a mm or 2, which would advance the total timing. It worked very well, but could get ugly quick if gone to far.

Great info Willie, keep at it!

 

[Six8five]

I thought the Gen3 ignition was the same as the Gen2?
Just because the PC5/6 can alter timing doesn’t mean that is physically possible on the KLR.
Does the timing even go through the ECM on a Gen 3?
Just asking.
Thinking that optimal AFR and timing will add more than 5hp seems overly optimistic to me.

AMEN!!!

That's one VERY ROUGH BUNG HOLE!!!

I have a guy about a 45 minute drive away that does Prop Repair. He did some Tig work on some VERY THIN Stainless before and it looked nice. I WISH I had a way to find someone closer!!! At this time, all I have on hand is a MIG.

Pickup off of a slug welded on the main/magnatized rotor correct? ....that would be "fun" to modify....

Just took a quick look at the Torque app connected to the bike. The ECU does monitor timing advance.....at least there is a live pid available for it.
This is good news and does suggest adjustments are very possible.
