Here is a link to a picture of it: ECU READY TO SHIP
It is located on top of the frame under the tank. You have to either lift the tank carefully (Ridem said you can get to it this way I believe) or remove it. There are some pics here with it installed that show you this, but I have searched for 30 mins and cannot find them.

You have to remove the left side cover and tank. Once the tank is removed its right there in the middle toward the back. Be careful when taking it out the support bracket is very weak. The left side cover removal is to disconnect the fuel pump harness. If you don't have a shop manual PM me.

Hey mike are you sending it to don at gulth motors. ? Me. & CIP sent ours to him for the flash. Is yours a 13 or 14 model. ?

Pardon the dumb questions, but
Are the flashes customized or do they have a set profile for CB1100's?
Beside removing the top speed limit, what are the other benefits?
If the exhaust has been modified, is that taken into account?
How much does Guhl Motors charge?

Ridem had a pretty extensive thread on this somewhere. But he will jump in and can answer all this.
No one has brought Don a stock or modified CB yet. The flash will take away the speed limiter, lower gear timing retard. I had the stock PC5 map flashed into mine and I'm running a full Yoshi and it runs great with no flat spots. Ridem32 had his flashed with just the restrictions removed. The cost is 375.00offroadfx4_imp said:
Honda could have easily tuned the engine for 100+ hp. I understand their reasoning for keeping things mellow and emphasizing excellent torque that starts at the low end.CIP57_imp said:
Don says an ECU reflash will unleash the inherent power in the engine. What exactly did Honda do to tame the beast (besides the speed limiter)? Did they retard or delay timing in just the lower gears? Didn't they want to emulate some of the engine vibrations of the old CB750s to give it some "character"? How did they do that? Timing?

I don't think this bike will ever see 100HP at the rear wheel, the cam profile won't allow that kind of power. There is power to be found in the ignition timing and a\f ratio but there is not much on top do to the cam. I believe the cam is also where the added a roughness to the engine as you mentioned.
I questioned Don about the lower gear restriction and why it did not improve 100% throttle input. He said it more in the 20-40% range, however the Yoshi full exhaust did open the bike up to some larger gains.

I had my speed limiter removed RPM bump up 500. Have all the gears with the same timing as 6 gear. Meaning the first 5 gears the timing is advanced more than stock. My bike runs great. But Don does want a CB1100 in his shop !
Mine is a 14 deluxe. Someone on this forum is taking a cb to Don soon. I added the comet 2 fairing and did the flash. My last trip I got 61mpg. And my other deluxe got I think 52 or 54 stock and it's brand new. That was a 140 mile ride average speed around 60
He also overnites it back to you! I sent mine to him overnite and had it back in 2 days. Don is a great guy. Just tell him what all your doing to your bike. Tell Don that mike from Mississippi told you to call him & to treat you rite !!

DONT HAVE A SHOP MANUAL BUT IT IS JUST THOSE TWO HARNESSES THAT NEED DISCONNECTED AND ITS OR IS THERE MORE TO DISCONNECT here you go:
Burn off some fuel to make the tank lighter
Remove the left side cover and disconnect the fuel pump (black connector) start the bike and let it run till it stalls. Turn the key off and disconnect the negative terminal. Remove the tank bolt and raise the tank as high as you can and support. Disconnect the breather hose. The fuel line has a rubber ring with a tab, pull it out of its position, than squeeze the tabs on the fuel line and pull apart to disconnect. Pull the tank to the rear to disengage rubber mounts on the front.

Like CIP said: remove the left side cover unplug the fuel pump wire connector! Remove the one 12mm bolt at back of tank! Lift up tank in rear there is one black hose just pull it off tank! At this time I move tank back about 2 inches and I use a rubber mallet to lay between the tank and frame so that I can get my and under the tank to remove fuel line. You can look under the tank from the rite side of bike and see the fuel line connector push the green tabs in and it will disconnect. You might get a little gas on ya but after that it want leak. The manual says pull the fuel pump fuse and let it run till it dies. Slide tank back a little more to clear the front mounting rubbers then lift front of tank off bike. It's a tight fit I tilt the front of my tank and back and forth. But it will come off. Unplug the 2 wire connectors on the ECM and the ECM has 2 clips one on each side ECM comes out very easy!! Best to remove tank with less fuel in it. It's heavy if it full of fuel. When you try to unhook the fuel line you will see why I use the rubber mallet to prop up back of tank. But you can do it. Just take your time. Don't scratch your tank. The hardest part is the fuel line.

And that fuel line may be "holy crap this thing will never come off" but it will. When squeezing the tabs, do not use pliers (manual warning).

Thaks for the great r/r proceedure on the ECU.Lord Popgun_imp said:
havent been able to accomplish this yet do to home repaires following the move in, but plan on getting it out, shipped ,and back in before Jul1.I will let you know my thoughts on the performance changes to the ecu once installed,and riden.

I've been following Cip's and Ridem's reflash threads for a while and reread them god knows how many times. My thoughts were that my UK spec 2013 AD model could not be speed limited. Before I bought the bike I had studied all the reports and road tests in the UK biking press, there had been no mention of this and even in one comparison test with the 1983 CB1100F the journalist wrote that he felt the new bike would probably not max out at 141mph at 7500 revs (peak power) in 5th, and that it was unlikely to top 125mph (an interesting article that I may scan in for you all sometime).
One of Tortuga's posts reinforced my belief that California could only possibly have had its way on the US spec bikes.
Next I researched ECU reflashing in the UK and to my joy found the agent for a US company "Ecunleashed" was just 30 miles up the road. A quick phone call to the girl and I was told the price included reflash and a dyno tune. My dreams of riding my possibly restricted 110mph sloath there and returning on a 140mph rocket ship turned to dust when the top man phoned me an hour later - "we don't do Hondas". Pardon? Probably the world's most popular motorcycle manufacturer? "No too much hassle, we have to send the ECUs over to the States, might as well do that yourself".
So I contacted Ecunleashed and they replied with a price of $499 plus $50 for shipping back and that they run Honda ECUs on the 1st and 15th of each month. They also sent a link to a tune file http://ecunleashed.com/order-form-tuning-files/ with a password of "tuning101". All good stuff.
But what of the bike wasn't limited? ECU to the States running the gauntlet of UK customs on the way back demanding 20% tax plus import duty?(gotta pay for the health service here somehow). This could work out to be an expensive bit of reassurance.
So, off with the tank. What joy, last time I took this off the air was blue and so it was again this! Would a couple more inches of fuel hose and a decent coupling really have dented profits that much? My thinking was to compare the serial number of my UK ECU with Cip's US one pictured above :
I don't really know what I thought that would tell me?
Riding back home the other day the question was burning me up. I turned off the main road into a small back lane in the middle of nowhere, put the bike on the centre stand and let her rip. I blame the pair of you for this crazy stunt and hold you both personally responsible! LOL! If I cling onto the front brake I thought "wisely! !!!!!!" the thing will only do a massive burnout rather than wheelie off down the road and smash itself to bits! Oh really? What a fluffing eejot!
The test results? Oh yes, the reason for this post. The wonderful moment when the speedo buried itself at 140mph at 7500revs quickly turned to horror as I thought the motor had dropped a valve. With a poping and a banging the speedo shot down to 110 then immediately back up to 130 and then back again with a huge fuss and misfiring. Enough! Rev test in 2nd next. 9000rpm and a repeat of the miss firing world championships.
I rode the last 5 miles home slowly and guiltily that I had subjected to my pride and joy to this horrendous ordeal. My guilt turned to anger with Honda. How dare they strangle my bike in this way for some rules and regs from a foreign land, the same place that killed off my beloved 2 strokes. Nothing personal you understand Californians? Christ, bikes aren't even checked for emissions here in the UK (yet).
Right, so reflash it is, the only question being to go with your man Don or these other people? Of course the money is important but as ever that should not be the whole story.
Thoughts and comments most welcome.
Another of my long tales I am afraid.
Cheers
