untamed, one must know the difference between open and closed loops going in. Justin does not need to make comment if it's already a given, meaning, both systems and how they are tuned. Closed loops back to a (stoic type) preset. Open is looped to any [frequency] tune you throw at the injectors and presets to that. One is adjustable, the other is not. Thus the toggles to flip the 02 off and run in method without sensor.

Just saw this post again after trying to assist another forum member.

After the unfortunate facts have already come out about the guy and he is no longer in business around here, I don't have an issue naming the flasher referred to in my above posts.

Cblast...

Hey guys, I have been reading up on the issues pertaining to gear stutter and unfortunately now my ride is doing the same thing.As others have stated, I am experiencing severe Stutter/Hesitation in 1st and 2nd gears only around 3-5k rpms. I live in the US and have a 2012 Zx14-R heavily modded. I run 16/43 gearing/Flies removed/Full brocks Penta Carbon exhaust/Sprint Racing Filter/Pair Valve System removed/Ape CCT/ EK Chain Heavy Duty 530 pitch/Steel Braided brake lines/ HealTech QS/
PCV to name some. I have never had this issue beforehand at any time and thats even when I went from stock gearing to 16/43. I had my bike flashed by Nels at 2wheeldynoworks and it ran perfectly. But since adding brocks Penta carbon exhaust and talking with him about maximizing performance, decided to try his Brock ECU Flash/PCV tune package. As soon as I got my ecu back and plugged it in, This issue arose. Only other thing I did do was mount a new rear tire to my rear wheel in the process of waiting to receive my ECU back from brocks/Don Guhl. I have since inspected my fuel pump...cleaned and replaced the screen filter , dropped new spark plugs in, reinstalled the Secondary butterfly valves, checked all grounding connections, inspected breather hoses, Unplugged PCV and tested (still present), Cleaned air filter to no avail. I have no codes coming up at all. Has anybody found a factual explanation for this or are we all just screwed. Thanks in advance.

If it happened directly after the Flash and everything was fine before it, go straight back to Brock / Guhl and get them to support their product and resolve the issue...

Did you use the same size tire? I've read several members' issues when changing sprocket size, so was just thinking a tire diameter change could be similar.

Copy that @Yannih! Ive been in contact with the Brocks shop manager back and forth. @Extrapolator As I stated in the initial post My bike was running perfectly fine, was running a flash done by Nels at 2wheeldynoworks with 16T/43T gearing and riding Pirelli Angel GTs 190/55/ZR17s ..Nothings changed beside me putting a PCV back in my bike and having my ECU flashed by Brocks/Don Guhl.

The cool thing is they are offering a full refund and revert to my ecu back to stock.. but the dilemma still is , what if this problem still exists afterward and then I go somewhere else to have it flashed and it still is present? Such a headache!

**PROBLEM SOLVED!? ??????**

Thanks @Yannih and everybody else.
So... it was definitely nothing I DID Wrong.
Somebody dropped the ball between both companies relaying information or just not paying attention. I talked to Don Guhl today, sure enough he has my ecu and information on file... asked what gearing was was i running, I tell him 16T × 43T ..he says what... I had down 16T × 42!!T....???? ...Then he starts to explain the symptoms that would happen because of that mix up and it was on point. Basically My ecu was tuned to the wrong Gearing configuration hence the reason I had only some stuttering/sputtering in certain gears. The ecu and sensors were becoming confused and trying to correct. ??...All is forgiven... I dont know if it was Brocks side or Don's side that had the error but mistakes are mistakes.. ECU has been shipped straight to Dons shop for correction. Just happy to get this resolved..and hope its 100% when I get the ECU back this time!

Wow, great I wasn't aware flashes were gearing-specific. Good to know.

@Extrapolator yea thanks bro.. im telling you I was like whaaatt!!!? Lol but then I got to thinking those guys are probly always busy and flying through orders so I could understand how they overlook certain parameters etc accidentally. But yeah The Good Tuners tune according to your gearing. Nels does that also with 2wheeldynoworks. Im just ecstatic that this goin to be resolved. I been pulling hair put the last week in a half lol. Thanks again for your help!

When it comes to flashes and their potential challenges, I wouldn't bet my last dollar on them.
But I would bet a fair chunk of that on Don Guhl.
A well respected, experienced and knowledgable flasher thats been around for a long time.

Really glad you potentially have it sorted and here's to your ECU being returned adjusted and the bike running perfectly...

Update: So... I will say it is not only the little guys that make it difficult in the tuning world. I can easily say I WILL NEVER DO BUSINESS with DON GUHL or Brocks Again in the ECU department! Before I was trying to be understanding, now I'm pissed! So after the problem is diagnosed as a ERROR caused by THEM(Brocks/Guhl) ,inconvenienced already for about a week and a half now going on... PAY MORE $ to Ship the ECU back to Dons Shop to get corrected. They finished the ECU today.. Im at work and get a email asking ME!...The **customer who paid just about $400 for a tune that has been nothing but a damn headache so far..to PAY TO HAVE IT SHIPPED BACK to me! Oh the f*ckin nerve! I dont even comprehend how they believe this is the correct way to respond to a F*CK UP caused by them that I pretty much diagnosed and found out myself.Spending hard earned money I did not have too.. Not only could they have damaged my ride... could have damaged me! When you make a mistake you do right by people. I sent a stern email responding to Guhls email with both companies involved and they better get it straight because if I have to a lawsuit will be coming down the pipe! I will never look at either one of these companies the same when this is over. **BEWARE!**

* Last updated by: Kabcar on 12/9/2020 @ 4:45 PM *

Yeah, that would be quite annoying .. if it's cut-and-dry their fault that they overlooked information that was clearly given to them.

@Extrapolator Don Guhl admitted it to me on the phone nonchalantly and then acted like I was bothering him. Then had the nerve to tell me they usually charge to make corrections but he'll just do it if I send it back. (I ignored all that trying to be diplomatic) He also threw in yea somebody will have to pay for it to get shipped back! WTF! (Again ...ignored his ass!) Then got the email today asking me to shell out more money and energy like I haven't already PAID A PRICE + $400! I emailed and forwarded Guhls request to Brocks and told them I'm tired of this, You need to pay for this and overnight that sh*t back to me..I got it there in 2 days flat. Im still being inconvenienced..I am a customer.. I paid full price.. I didn't get over on you and pay for partial service. Hurry up and make this right! This is beyond ridiculous especially for 2 companies that claim to hold their selves to such accountability and quality! TRASH! ...never again!

Yeah, sorry about that Kabcar.

If you read my flash story, you will know I know exactly how you feel.
I was mighty pissed at the time.

Live and learn...

$400? Takes a wall socket to hot the 12v going to the black box. Takes a toggle and a few sips of coffee for the pc to cycle up. Where are we at... 3 minutes so far? Keyboard gets a few taps and now drag and drop the generic ECU package and ship it out. Took what?... a total of 8 minutes, give or take a sip between closing down the pc, packing it and write your address on it?

Oh shit it's a comeback... time is money so I eat it... That's right Don, you fucked up and you eat it. You made a killing on each pc for a decade at least. You are going to satisfy your customer for the price of shipping out a few bucks off 400 large. Write it off FFS. Fight that greed, motherfucker! You're looking bad in the eyes of the public right now. For what? Chump change worth of grief?

Squeak much?

Kab, customer is always right.

Okay, I've been reading this with interest. I have a 2018 completely stock 14R except for the exhaust. My friend, guys and girl and Cycle Gear, other riders, and you read on almost every forum that a power commander, bazzzzaz, or flash is a must! You have to do it! I've been reluctant and not done any changes.
My friend did a flash and bazzaaaz [I don't have a clue how to spell it]on his ZX10. Afterword for about a year he had terrible running, abrupt shifts, and even some stalling. He ended up dropping his bike in a corner because of this! He was always taking it apart and adjusting something! He also felt that he was ripped off by the shop in Seattle that did the flash too as they were no help at all and simply wanted money to examine "their" problem.
My question is: has anyone done a flash or other similar add-on and experienced no problems at all? Does everything work as it should with all the benefits promised? Thanks.

I shoulda read more, but gearing wise, where are we on that? If you sent Don the wrong gearing, shipping is on you. Because Don read off another set as I read more... Don may need a brown paper bag from me... we'll wait.

Admitted 'ERROR' stated on the returned ECU does not look good for someone. Last flash, looks like it's on Don's end.

@Yannih yea bro crazy.. I was livid and not a mean person at all. I understand we all make mistakes but when you act as if you don’t care and aren’t going to make that persons situation whole again.I have a huge problem with that. @Hub I was cracking up hell yeah bro, RESPECT THE Paying CUSTOMER! And there absolutely is no doubt that the error occurred on their ends. I have The receipts to prove it. I guess they read my email this morning because now they are overnighting the ecu back to me on their dime rightfully so! Might be a damn good tune but because of this situation and the way it was handled I’m kinda skeptical of even that at this point.

Kabcar - OK it sounds like it's heading the right direction now I have definitely had to get ugly with vendors before to get them to make something right. I didn't like it at all since that's not my nature, and afterwards while all was made right I still didn't feel good about them. Suck situation.

nord,

My question is: has anyone done a flash or other similar add-on and experienced no problems at all? Does everything work as it should with all the benefits promised? Thanks.

I paid $75 for Schnitz's basic flash + $125 more for "Adjust Fuel Tables to Match Exhaust" for my Muzzy slipons, and I've had zero problems. That said, as I've posted on here before, if it improved performance I don't really think I can tell it. Now that could be because I don't drag race, roll on race, or any other kind of racing; just a fast blast with my buds from time to time on weekend lunch runs. I mostly wanted to be sure the bike's ECU's and fueling potential was maximized, was interested to see if I could tell, and I liked that the Power and KTRC settings are retained from last time each time I restart the bike. Now maybe there are better flashes, and if I had other mods maybe I'd be able to sense the flash better, not sure.

Still looking for, quote, 'gear maps'.

http://www.ivansperformanceproducts.com/12zx14.htm

'Fact check' is a western proverb vs a chinese proverb [Chairman Mao] "No investigation, no right to speak."

So Irish/Australia/USA-Ivan-Don says; 4 different flash hacks into the mapping. I do not see gear maps, just toggle off the limiter, or just hold down ctrl+F for find, or hit F3 and type in the window 'gear' w/out quotes and I do not see one can change 7 gear maps... if that's what you were told.

Ivan has his own flash program and he shows nothing but backup maps triggered is my guess. Ivan might be showing a backup showing the lower 3 gears can be disabled from the k-skid. That's my guess. Why the others do not show this? Now Kab, I don't know if Don toggled off the lower 3 as Ivan seemed to discovered> I'd have to see his [Ivan's] screenshot. But to me, that sounds like cutting off the k-skid so you do not get the sprocket change at said certain rpm/gear combo's like you are experiencing.

Error found is brick speak for all I know. Since there are no moving parts inside the black box, but magnetic gates of 5v holding that gate hot or on, or 0v closing the gate off. Flash wise, I think I read kawi's kit-ECU abstract saying something like, 'you are going to degrade the chip, so you have 65,000 cracks at the chip... literally.' I took that as, busting the crystals inside the chip, and it still has a path out from one touch to the next of those rearranged silicone sand molecules... magnetically speaking.

And you can play with the mapping where it holds you hand in a way. And that way was, if you typed in the wrong number, it would fly out of the map box and have a -/+ being said as an 'ERROR' outside the map. It says that won't calc off the other numbers around it.

@Nordicwargod Sure have... The Flash previous to this one.Had my bike Flashed by Nels, another Respected Guru Tuner twice and He did my wife's bike. NO ISSUES EVER!...Noticeable performance gains and silky smooth! Checkout 2wheeldynoworks
