Ok so a while ago I had decided to get a reflash for my ECU to get rid of all the piggy backs. I’m doing a top seep event in July and wanted to make sure my limiter was off and the rpm limiter was raised by 500 rpms. I sent the ECU to Dynotronics in TX for the job. At the same time I had Jim from Competition CNC in CT do a Super Sport head and degree the cams. When I got it all back together and put the bike on the dyno we ran it up and it still shut down at 11,000 rpms! So I call Dynotronics and they had me send it back and they were going to check it and rise to 11,700. So now this would be the second time shipping it overnight so I wouldn’t lose any riding time….I got it back and put it back on the dyno and low and behold the bike shut down at 11,000 again!!! WTF. After talking to Jim at CNC he recommended I send it to Don Guhl at Guhl motors. I over knighted it to Don and followed up with a call. Don was great on the phone and said he would take a peek. Well he called me back in 30 minutes and told me that they didn’t raise the limiter and they also F’d with my timing which I had told them not to do. Also they screwed with the fueling maps and only raised the speed limiter by a few kilometers. At this point Don suggested a complete reflash in case there were other things they may have messed with….
Don has done the reflash and sent it back the same day….I’ll have to do a total custom tune again thanks to the other guys at a pretty damn good cost not to mention the overnight freight back n forth to TX 4 times! But at least I know it will be right. Can’t wait to get it back and see how she runs….Moral of the story guys if you’re doing the reflash Don is the only guy…….

wow that sucks. any follow up with dynotronics to hear their side?

I havent come across any bad reviews/info about guhl's flash. Im starting to get my feet wet with all the performance mods now and a reflash from guhl or ecu unleashed is where im headed. I just havent decided if a pc5 is needed after the flash.

Question for you,
I understand what the flash does in terms of raising the limiter and adding timing down low (among many other things), is a pc really needed after a reflash? I know youll be able to add/remove fuel in the map but is it needed if the flash is done?

Thanks for sharing that Somefun.

If there is any reason that your ECU was flashed wrong in the first place, there is no excuse they did not get it right after sending it back 2 times...not if Guhl's could see it was wrong as soon as they looked at it.

I wouldn't bother with an explanation from dynotronicse. At this point, I would have no trust in that company. They shot their own butt and they were not even smart enough to cover it up. How would you NOT notice the most obvious aspect of your reflash wasn't working at all? That wasn't just dishonest on their part, it was plain stupid.

I've got the Guhl flash....timing tables altered'somewhat'....top speed limiter removed.RPM's raised by 200.Secondary opening times adjusted for sooner.I don't think they did anything with fueling.It pepped my 2012 up some.No PC.I don't think you'll actually need a PC...but in order to remap...ya...you will if that's what you think you need.

The flash works nicely....a bit more response than the stock config.Sounds like your bike is there already with the engine work and all.Good luck!You might just consider going with the Healtech Speedohealer version V...it WILL allow your bike to do as fast as it can as far as 'limiting the top speed'....it won't allow more rpms however...so if that's set....that's all you'll get...whatever speed that ends up being.It really sounds like you bike is ready except for gearing.You're not going to hit 200 with stock gearing.Flash or no flash(This I've read from reputable guys).

Yeah I’m not listening to Dynotronics anymore…..From what I found out they don’t even do the flash. They use a company in Italy that cracks the ECU and then they e mail the flash and then down load it…There is a big difference if you’re doing the actual tune or flash or just hitting the enter key to flash to send it. But I can say for sure GRN with 206 at the rear tire n 11,700 rpm limiter with 17 front and 40 rear she will more than blow away 200 plus……My girl has been on a diet for a long time now……lol

---

How bout an 18 up front,and 44 out back?That's what I was told.

On the gearing commander site a 17 / 41 at 11,600 is 219.....I'm going to bring a 40 also just in case.

---

17 / 41 at 11,600 is 219..IDK...maybe you WILL hit those rpms and listed speed....Fastest I got on my 07...stock motor with no secondaries,4 degree advance...stock gearing was 190.Had the top speed limiter disabled.I never was able to check my rpms when she stopped acellerating...I wish I had.If you've raised your rpm limits...you may very well push on past...but that last 10 mph....it's very hard to pull unless you have something allowing that motor to keep climbing.

Ya...I know...the gearingcommander site.They do mention in there...that these outcomes are......conditional.IDK...none of my setups with the gearingcommander site actually hit the listed speeds.Muzzy advised doing the 18,44 to hit over 200.(It MAY have been...18,40...but I'm pretty sure he wrote 18,44)18 up front definitely.

Like you said...you don't want to fall short by a few mph....may as well have a bit of 'overkill' ready...maybe take an 18 with ya also,and a longer chain?It's a once in a lifetime shot sounds like for you....I really HOPE ya get that T-Shirt my man!!!!!AWESOME.

You know....she's climbin up that tach nicely....speeds rollin on up....you're thinkin.."shit yeah,c'mon baby...keep climbin"..and it looks like she will....UNTIL......you realize.."FUC$$....she's not pullin anymore"...and right up there...so close...sayn to yer baby..."c'mon....I KNOW you can do it"....You don't want THAT to happen.OVERKILL....take some overkill!I know your head says...'Oh yeah...no prob".....

I think you will make it....I really do.

Thanks man I really want to... I'll look at that combo for sure thanks! I want to cover all my bases. I want to freak people out when they see us ride them there 9hrs and then hit the mark!!!!

---

"see us ride them there 9hrs and then hit the mark!!!!".....well...with that gearing...it may take a tad more than 9 hrs....but heck...the cops'll never catch ya on the freeway!!!LOL!

GRN I looked up the 18/44 and it no better than 17/41. Gonna try it!

---

Okay....I haven't looked there in a long time...whatever ya think will get ya past yer mark.And not by a hair either.I think that rev limit raising is gonna really help a lot....but ya gotta be concerned about just where that HP starts to flatten out....you want gearing that's gonna be good enough for when she DOES flatten out.And she will.....I would say...the 'straightlining' on the Dynos,up at the end rpm range there....that is enough HP and tq to get ya past 200...the only thing holding ya back will be wind and gearing...so go big baby!

on Brocks site he states all the 14 needs is a Brocks pipe a pc and 17/40 to break the 200mph mark

keep us posted somefun and good luck were pulling for ya

oh and if i remember right he said ceramic bearings too

pulled this off Brocks site maybe useful info....i dunno

I have your 200 MPH Package with 40 tooth sprocket, ceramic bearings, Power Commander Digital Ignition, Wideband Commander, LCD, no sec, multi function hub, etc. Maxton map kicks ass, do you have one with ignition table though? I’ve read to advance timing 4 degree’s 0-6000 RPM on some Ninja forums, and to retard at higher rpm’s. Have you tested this? I have advanced timing as stated above, but not retarded any in the upper rpm’s because no one has the numbers as to how much. Note: My bike riding style is for high speed, not drag.

Answer / Solution

I don’t like ignition timing changes at lower throttle openings/or rpms. If you have a detonation problem, you find this out by destroying your engine! I typically suggest 4 to as much as 7 degrees (with good fuel-example MRX01 ) at 6K and up in the 100% column only (added manually)-- for drag racing…. But I have no clue what to tell you if you are doing high speed runs. Some guys retard…some advance. It depends upon the situation/combination/fuel etc. I would be nervous to advance for high speed runs—but it works on the drag strip for most Kawasaki’s.

Here is my take on Dynotronics. Based on some long topic threads at COG.

Don Guhl worked with Harmon (COG Tech Guru, can take a C14 down to bare frame and back to perfectly running in an afternoon) until they got the C14 flash perfect. They hooked up the instrument LCD screen and put an analog looking (clock dial, but actually digital) for secondary butterfly opening, and bar graphs for rpm, A/F, etc.

Then they did pulls on the dyno to represent leaving a stoplight, passing, and so forth, and we could see exactly what Guhl's flash was doing.

So along comes Dynotronics, and he was cheeky enough to claim he was the one who first decoded the C14 ECU. And so we asked him if he would do a series of instrumented runs so we could compare it to Guhl. His answer was basically "trust me", and "I'm better than Guhl". So everyone pretty much let him know he'd get no business from most of us.

When I get towards the end of the riding season, I have a 2 week break, and I'm going to ride an hour and half to see Guhl, and get him to do a dyno-based workup and reflash my C14. Keeping the stock exhaust and all. Everyone who has done this says it wakes the bike up, without even the expense of an aftermarket expense.

Sure, we could get more horsepower with dual Muzzys, or Leo Vince slip-ons. But many of us don't want more horsepower, we just want it a little more responsive.

And Don Guhl can give us that.

I think that rev limit raising is gonna really help a lot....but ya gotta be concerned about just where that HP starts to flatten out...

^^I don't get the extra 700 rpm rev limiter. For LSR you don't really try to accellerate as fast as the bike is capable and even if you did, the peak hp is around 10K. Furthermore, the bike isn't going to hit the rev limiter in 6th gear. Even when the speed gets up to 200 you are not even close to redlining so why do you need the 11700 rev limiter? I'd like to have it just for fun but it doesn't do anything for performance, does it?

---

With the new super sport, degree the heads and 47mm TB the power necer dropped off all the way up to 11,000 so I can wait to get it back and see what happens we I hit 11,700 RPMs!!!

---

I'm not sure Rook what having those extra rpms will do...but from what I saw on some of the Dyno runs that had the rpms raised...the length of 'flatlining' at max rpm was quite long.Before the limiter kicked in and shut the power down.If I'm saying this right?That length of time may possibly give the gearing the time it needs to complete it's ability to fully reach it's top.IDK.When I did my high speed runs...the 190 one anyway...I could tell the gearing was reaching it's max...but unfortunately,that curve was coming up really quick...so....I never really DID find out if she could have kept pulling.I ran two back to back...in each case,I don't think I was entering redline...but the gearing still hadn't caught up all the way...least it didn't feel like it had.If that makes any sense?(on my 07)

* Last updated by: Grn14 on 4/30/2012 @ 11:19 PM *

Grn14 when I had my girl on the dyno last time after getting the head and cam work done the power just kept building and never dropped off all the way to 11,000. So I’m excited to see if it builds more the higher we go to the new limit of 11,700. I’m pretty sure I’ll build some more HP. I’m not sure how she’s gonna do at the Top Speed run but I’m hoping I make the number… I just saw where a girl on the new 14R made 201 mph in the mile. I’m hoping I make 200 big time and I’ll be doing it in a mile and a half. I know the 14R has some power over even my modded 14 but who knows. With the 1.5 distance that just might be the ticket!

---

"With the 1.5 distance that just might be the ticket"!...could be...I'm hopin!Even with her maxed all the way...SOMETIMES...you CAN get a few more mph with body position adjustments...a longer run gives ya that extra time to do that.
