He also told me that if you have an aftermarket can (not full exhaust), that'll get a different tune that a bike with a potato launcher.

It wouldn't be proper for me to NOT comment.

I doubt changing just the muffler requires a different map.... unless the replacement muffler is almost nothing but straight through.

It's all that extra weight Max, seriously changes the bike's performance metric to all of a sudden lose it. The ECU can't cope with it. Not prudent, you know.

: Just yesterday I left the oil cap off the Prius after checking it.... Nothing to do with this of course, but I think my mind may be going, if it hasn't already.

Last week I told one of my guys to check the oil in the new bucket truck ....... He said where is the dip stick and the oil cap

what a crew

The VH CS-1 is straight thru and that causes a decrease in back pressure which corresponds to loss of low end torque- believe it or not. The stock fuel map with the bazooka attached gives the engine more back pressure and torque as designed. But no way would I put that POS stock muffler back on my bike- I suffered a lot of embarrasement from my freinds and family before I threw that in a dumpster. Besides Connie seems to rev a little quicker from 5,000 up and sings a very pretty song- priceless. If only Guhl would concede $100. or so , I could have the best engine ever put in a bike. Is that asking for too much Mr. Guhl? Huh, Huh?

Guhl just called, they received my ECU this morning, flashed it and it's already on it's way back by FedEx. Weather permitting I'll be checking it out this weekend. That's customer service!

good way to fry anything electronic Lord knows, I've fried my share....cut a 120v power cord with dykes (got a small mushroom cloud with that one), fried a very expensive tape backup drive, and on and on and on. You would think I would learn. Just yesterday I left the oil cap off the Prius after checking it.... Nothing to do with this of course, but I think my mind may be going, if it hasn't already.

Going, going, GONE.

I'd leave that up to the expert...

I posted the text from Guhl about this but in summary, he said that the program for a bike with a V&H is slightly richer than the one for a bike with a stock muffler. He also added that you can run the aftermarket can tune on a bike with a stock can.
This was in reply to "if I have a stock exhaust, should I send the ecm back to you if I switch to a V&H can?"

I sold my 2011 bazooka to a forum member for his 2009 bike for a crisp $100 bill.

He said mine looked better than his old one.

Got the ECU back from Guhl this morning as promised. Installed it at lunch and the bike fired up no problem and no lights or warnings of any kind. Still ice and snow on the road so will not be able to check it out until maybe Sunday. Pulled and sent it last Friday afternoon and its now back in the bike working. Great company to do business with!

The sun melted off the snow and ice from the roads nicely in the last 2 days and I had a chance to check out my new ecu reflash. The difference between the ECO map and the normal stock map used to be subtle. Noticeable but subtle. The difference between the unchanged ECO map and the Guhl "GUTS" map is pronounced. I can feel it mostly in the mid range rpm. I can also hear the difference.

Also tested KTRC and it worked perfectly. No change to the functionality of traction control at all.

If you are like me and wanted to pull the flys and add a PC-V but were concerned about the affect on KTRC this is a nice alternative IMO.

How do you go about getting this service done? I don't see anything on the
Guhl website about mailorder flashing, much less an order form to fill out and
tape to a ecm.

VirginiaJim · « **Reply #113 on:** March 02, 2013, 08:50:37 PM »

Give him a call. The number is in this thread somewhere...

+1 Call Don at 717-618-4212. He will have you ship your ECU with your contact phone number to:

Guhl Motors:
4126 Oregon Pike
Rear Building
Ephrata, PA 17522

Once he receives your ECU he will call you, confirm what you want done and get your payment information. The $375 includes return shipping. My ECU was only at his shop for a couple of hours. He received it Tuesday morning, called me, flashed it and by that afternoon was on a FedEx truck for return.

Had a chance to ride the bike about 150 miles today. The GUTS re-flash ROCKS. The bike feels significantly stronger between 4500-6500 RPM then stock. It always was effortless to pass on this bike but now it's even better.

The gains with the flies out of the way at less than wot are impressive.

You wanna know one unexpected thing I like about my flashed bike...the sound of the carbs opening and sucking air in....very throaty!!!!! I guess the same would happen on a bike with the flyectomy.

Note: I have the stock exhaust so I can hear it vs a louder pipe.

I hope your Concours 1400 doesn't have carbs
