I went w/ Guhl/Brocks & couldn't be happier.I am planning to have my H2 reflashed, so I am trying to figure out who's best to reflash my baby. Ghul or ECUnleashed?
Nothing comes 'locked' from Brock's Performance. We work directly with Guhl, but have a little different means to an end. We use a PCV to control fueling, this way, if the customer wishes to make adjustments to the fuel map - it does not require an ECU extraction (a royal PITA on the H2). This also allows for dual fuel maps to be selected at the flip of a switch (race vs. street etc.). And allows updated fuel mapping/tuning help to be sent via e-mail. Any internal ECU map updates (addition of auto blipper, 200+ MPH speedo etc.) are free - the customer simply pays postage.I don't like the idea of an ECU being "LOCKED". It doesn't come locked from the factory.
Hopefully I'm wrong but it sounds as if this virtually renders the box useless for any future tuning on the part of the bike owner.
If that's the case, hopefully Guhl has this posted on his site for potential customers.
mikesh2 very sorry for any misunderstanding. I would hope no one on the Brock’s Performance customer service team would have told you your ECU was locked? However, our policy is to advise you to return it directly to Guhl for any/all internal changes (and that this is typically at no charge ) – you just pay shipping.3 months ago I installed supercharger gears in my H2 with a brocks stage 2 Kit. With no maps available for this combination from Brock's I opted to take the bike to a professional tuner. He said with the added boost we would need to pull some timing out of the bike. So I purchased a woolich racing on the bike flush kit. Dyno tuner said some companies will lock the ecu's after reflashing them and I would need to check with the company that flashed it to confirm it was not locked. The next day I called Brock's performance the guy on the phone said he did not know and put me on hold. Came back a few minutes later and said yes I would have to remove the ECU and send it back to Don and he would unlock it turn it back to stock and send it back to me. So what you are saying is contradicting what your staff told me on the phone. I will install the woolich Box and see if I can access the timing in the ECU thanks for the information
Guhl does it to protect his files, his work product, I get it, I understand it, .
With all that said, I certainly hope that my posts on this topic aren't coming across as a slag. I was inches close to buying the Stage II Guhl Flash myself, but having to send my ECU was a deal breaker for me. Had the ability to tune on the fly been presented I would have absolutely went with his package. ...and for the reason you mentioned. All of the development.I get it too. There's only a couple of choices; Stage I or II. It's not like there is a large # of engine mods/combinations to consider, theres only a couple that Brocks Performance recommends for the H2. Slip on vs full exhaust, stock redline vs 14k w/ a PCV. He doesn't currently recommend super charger gears or other mods so why would Guhl want people changing his work, adding mods not supported or even not recommended w/ the greater possibility of something bad happening w/ a Guhl/Brock reflash.
I think there's a handful of H2 owners that understand the technology & engineering enough, folks w/ an extremely high level of competence that are using the gears w/ an intercooler, tune for LSR so there's definitely a place for the gears. I doubt it will happen, not really what you call "bolt-on" but if Brocks Performance gets involved w/ gears down the road & they'll fit as well as OEM, w/ a recommended intercooler, different fuel pump, reflash tune specific to a gear package & says I can safely/reliably run it on my street bike that I use in the summer for thousands of miles then it would peak my interest, until then I'm good.
Honestly if it were my reflash/parts business I'd handle it the exact same way. Stage II adjustments to the fuel mapping can be done via the PCV. Street Map or Track Map, I can switch between the maps in a few minutes at home, a lot easier then pulling the ECU on a H2....LSR & want to run the same map that broke mile records then download & run it. But I get not everyone wants to run a power commander.
At the expense of sounding like a fanboy (and that's fine) I'm not going to modify my H2's in anyway above Stage II that hasn't been given Dons & Brocks stamp of approval/unless the parts are available from Brocks Performance, just not. IMO 12 weeks doing H2 R&D work on the dyno, countless hours of research in the shop, out racing & beating records, plus the largest modded H2 customer base to get feedback from that are running their bikes reliably, I'm pretty confident they know what they're talking about.
Agree there are people capable of editing a flash but for every one of those there's probably 2 more that would do more harm than good and then instead of providing customer support you're trying to sort out messy, technical problems that could have already caused harm.
There's other reflash options out there & it's a free world (mostly anyway) but on the H2 no one has put in the time & effort w/ a level of expertise like the guys above. While helping to put the H2s awesome reputation on the map, breaking records, they provided me w/ a reliable, insane sounding & performing motorcycle in the process.
I get that others prefer to do things differently and that's okay but w/ all due respect have to say I think the tone is maybe a little harsh. Honestly, this isn't directed at any one post or anyone specific, it's just something I've noticed over the last 6-9 months - think its probably one of the reasons the forum sees so little contribution nowadays even though there's many more H2 owners out there. In 2015 when the board was more civil, polite, respectful & didn't get personal this was a much better place. We already ran off a number of posters, people from companies that came out w/ H2 products, a well known racer, another with a high profile YouTube channel, others that left were just interesting H2 owners from around the world that I would have loved to hear more from. Come on fellas, we can do better.
