The 2 into 1 pipes will have better scavenging effects because the pipes are joined and will help each other to 'suck' the exhaust out of the other pipe and therefore out of the other cylinder before the exhaust valve closes all the way, this helps by creating more room inside the cylinder for fresh air and fuel to create a 'bigger explosion' on the next combustion cycle, so properly designed 2 into 1 pipes 'should' always create more power than dual pipes, this is the same theory behind headers in automotive applications. So I was asked to give a little more info on the difference between the 2 flashes as far as dual pipes OR 2 into one and while I am not privy to the exact differences as I am not the one actually doing the Reflashing I will do the best I can.ĭual pipes and 2 into 1 pipes have different flow characteristics do to the design differences. We are getting approximately a 30% gain in power at 4800rpm which is massive and power gains through the entire RPM range. There is no need for a fuel controller this does everything for you with no piggyback controllers required. The timing has been advanced and the fuel maps optimized to give you the best performance possible.

If you don't follow this procedure, don't complain about stalling.īasically Don goes into the ECU'S software and reprograms it and gets rid of the factory restrictions imposed by the EPA to make the bike run as it should if the government didn't make Honda jump through hoops. High octane fuel is recommended with the flash as the timing has been advanced.Īlso when you reinstall your ECU be sure the first time you crank the bike to just let it idle until the idle drops down and the cooling fan turns on (this may take 10-15 mins depending on the outside temperature) DO NOT TOUCH THE THROTTLE!!! The ECU is relearning the IAC valve position.

If you run these tunes on stock intake and exhaust it may run a little on the rich side.

Your intake and exhaust play only minor factors, any free flowing intake and exhaust are going to be about the same. These 2 flashes (duals and 2 into 1) have been dyno tested on Scott's (GSK1966) bike with a cobra powerflo intake and freedom performance dual exhaust and then with the same intake and STG 2 into 1 pipes.

The thermostat starts to open at 176° and is FULLY OPEN at 203° so by setting the cooling fan to turn on at 205° it will not run as long as you are moving with air flowing across the radiator so its not like your fan will be running constantly. this is a great option as heat is a major enemy of the engine, the oil, performance, and it is cooler on the rider sitting in traffic. You can opt to have the cooling fan turn ON at 205° and off at 201°. Cooling fan = the stock cooling fan turns ON at 225° and OFF at 221° I wouldn't push it any further than this and when you see the dyno map you will understand why.Ĥ. Most people go for 6100rpm there are a few of us a little more daring that opted for 6500rpm. if you have him set it to 10,000rpm and blow your engine its your fault so be smart about it. its your bike so you choose but remember no one will be held responsible for your choice except you. You have the option to raise the rev limiter to whatever you feel comfortable with. So if you want to break 100mph you simply raise the rev limiter. Stock 5th gear=4800rpm (this is how the bike is limited to 100mph by lowering the rev limit in 4th and 5th gears) Rev limit= stock rev limits are as follows: He can lower your idle down to 660rpm but most people choose 700rpm so as to avoid stalling.ģ. Idle= our stock idle is 930rpm after the bike warms up.

choose whichever is closest to your setup.Ģ. Turn around time is extremely fast if he receives it Monday thru Friday during business hours he will flash it and ship it back out same day. The flash costs $375 (cheaper than some fuel controllers) and that includes free overnight return shipping and comes with LIFETIME REFLASHES you just pay the shipping. So first off let me start off by giving you Don Guhl's contact info, he is a great guy to talk to and extremely knowledgeable with stellar customer service. Thanks for your cooperation in this matter. If you have questions please feel free to contact me through PM or in the other thread. I asked one of the moderators if we could set up a thread that only I could post in to keep the thread from getting cluttered up but I was informed this wasn't possible so I am requesting that this thread not be commented on or questions asked in it. So I have had alot of members asking for a consolidated version of the info found in the ' Holy Grail' thread.
