Anyone else have theirs done.

The canned tunes you get with the power commanders are crap also way way rich. You should look into getting you ecu flashed to derestrict the bike and just get a tune in the stock ecu.

Dyno numbers are negligible every dyno reads different you could put your bike on a dyno and have it show 100hp take it to another shop and show 90hp. The way to do it is to get a baseline dyno run before mods then dyno pull after on the same dyno. For example my zx10 pulled 173hp on guhls dyno...

As far as adjusting your fuel tables if you do want to go with a power commander I have had to dyno techs tell me that the auto tune with the wideband works really well and if you have access to a dyno you can get an ignition module and play with timing. But you are still going to be working at...

The cat is very easy to nock the guts out of. I recommend it as it also helps to unstuff the bike. But yes the ais adds clean oxygen to help the cat burn efficiently. And ye he is the man on the gen 4 zx10 mine put down 158 before the flash and 170 after the flash here is a pic of the graph and...

We can make it simple you tune your bike with your pc and run against my bike with the guhl flash I am that confident. A power commander and ignition module cost more than the flash it self and the pc can not control sub throttle operation and removing the flies or modding them is not the answer...

What kind of gains did you see? Do you have any dyno charts to show numbers compared to guhls. All dynos read different so a before and after to truly show the gains

If you read the entire guhl flash the flash was developed at guhls on his dyno with my bike. There is also an attached video of the bike on the dyno with dyno charts. So with that said he can change the fuel tables in the factory ecu to accommodate the mods on the bike.

So did you get your ecu back and have a chance to try it out

Don't buy this number Yamaha 5SL262400100 Grip Assembly its the same as factory so who ever put them numbers up was wrong but with that said I modified it to make it a 1/4 turn.

well you have the tank off you should pull the ecu and get it flashed

Not a dumb question. Yes its always good practice to disconnect the negative terminal. This prevents the chance of a voltage spike that could damage sensitive electronic control modules.

I am wondering if this issue is due in part to the spring on the rear shock being very soft I have noticed when exiting the turn hard that the shock has bottomed out. That being said the when the shock bottoms out load would have to be absorbed somewhere in turn bending the side plates. Race...

The heat is in the tools my friend just turn on some tunes and go to it.

Another way to get ahold of Don is on facebook guhlmotors has a face book page

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.

never heard of flash tune on any forum I belong to. I would be hesitant to send my ecu to just any joe blow who thinks he knows what he is doing. Guhl is known worldwide.

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.

Flash is the same price with just derestriction or with fuel tune for mods and derestriction.

looks like everyone is finally opening their eyes to what a great mod this is.
