yes that is correct once you pay for the flash if you make changes they will flash it for free you just gotta cover shipping.

I believe that flash tune will as well, but I'd have to mail it to them. I can just pull it out and drive to Guhl motors when I get an exhaust and k&n filter.

Agreed, I have used and trust Guhl completely. Not saying Flashtune or the others aren't reliable but Guhl's work is just stunning!
Right, that's what I meant. I read on the other forum that Flash tune will do it for $100 if I take it out and mail it. I only have a slip on.
You get what you pay for. I don't know how long everyone has been around, but I've done a lot of building and tuning long before electronic ECU mods were available. Back then a guy could spend hundreds (and we still do) on just a slip-on, which are all the same (nothing more than a straight pipe with an attractive can wrapped around it). The power doesn't come from the slip-on, it comes from re-jetting the carbs. That's days of work, minimum, and several dyno runs to get right. So we used to have to throw the better part of a grand at a bike to get more power.
With the Guhls reflash I just had done, I got more power than a pipe, air filter, and jet kit could have gotten me, for a third the price. They got it right, my bike still appears bone stock, it's still quiet so the neighbors and cops don't hassle me, and it's FAST.
I can recommend Guhls, but it's like doing research on your own. What they are doing over there is something they had to figure out by doing tons of testing, and their file which is written into the ECU is their own little magical combination of mods. It is not like there is just a common ECU flash file and anyone can get hold of it and upload it, like a game cheat or something.

When Guhl used my bike to create the fz8 flash he actually bought another fz8 ecu to use on my bike for testing so he did not screw my ecu up. this is not guhls main business he does a lot in the micro sprint car which use our engines so they know how to get everything out of them.
Let us know how it works out!OK you guys have convinced me ~ I shipped my ECU to Guhl today
You were the "guinea pig" or lab rat here? Whatever the hell they figured out, is awesome. I am still flabbergasted at how much better my bike is.

Just plain crazy...
He can do a flash for anything or nothing..... He's UNLOCKING your ecu, not just "tuning" it.
If you upgrade parts, call him and if I'm not mistaken..... You pay shipping and he will "upgrade" your tune for free because you already bought from him.
At least that's how I remember the conversation going.....

Banky is right. He will redo a flash for free if you make changes. I'm planning on getting mine done on a stock (performance-wise at least) bike. When I have more funds for exhaust and k&n filter I'll have him redo it. It's easy for me though, since I'm within driving distance.

The air box needs to be removed to get to the ECU, I'm doing the air box mod and AIS elimination this weekend while I wait for my ECU to get back.

Did you tell him you were going to do that? Or is he reflashing you for those mods?

I haven't told them yet, I called before I sent it and he told me that someone would call back after they received it to discuss options and bike mods. I got the impression that he could flash for about any mods. You think I should hold off until I hear from them?

That was pretty much my plan..except do the mods...then ship while bike is still apart so down time is to a minimum..

No, no you're good..... As long as they follow through or you get ansey and call him and tell him. Lol just make sure that it gets added to the flash BEFORE it's back in the mail or you'll have to wait for another week for him to flash it with your changes lol.
The cool thing about a reflash is that everyone forgets that "you're UNLOCKING the ecu" and THEN optimizing the tune for whatever mods if any.
The biggest gain here is the ignition timing that the ecu restrics is now gone.
When I had my PCV tuned, the Dyno tech showed me the spots that he couldn't tune. He said here's where I added fuel and smoothed out the "this and that" and it was all cool. I asked why he couldn't tune in almost HALF my rev range, and he said "the ecu is locked.... I can't do anything about it"
Anyways, your gonna love it. Mine is working really well. I really think my midrange is stronger with my flies in and the ignition timing being changed.
But I'm by far no expert at all of this.
