This comparison consisted of riding around, testing functions, and dyno pulls. For this I had my ECU re-flashed back to the last version which did not add fueling but removed the lower gear restriction (cough), Top Speed limiter, and a few other bells and whistles that escape me now... I believe there might have been fueling left in, and Ivan said it also. With that being said, here is what I found out regarding the flashes.
First thing we did (Ivan and I) was to put his flashed ECU in my bike and ride around. I honestly thought my bike was running the same with both ECU's at first I did not notice anything ground breaking and said "If I didn't know that you swapped these I would never have noticed". That was after a quick 5 minute blast, literally. When I mentioned this to Ivan he told me to go on & off the gas at low RPM's and notice the response. I did notice that his ECU was a bit more responsive. Next we took the bikes out and did some rolls from 2nd and the "safety" mode has definitely been removed from his ECU, mine has definitely not..... After that I took his bike out and he told me to go 2nd gear 5K-6K and go WOT, which I did several times and his bike is much easier to wheelie (stock ride height). Well after this was all fresh, I popped my ECU back in and went for another blast on my bike with my ECU for another comparison. The differences were more dynamic after riding around with back to back ECU's, and his KTRC stays in the last mode it was left in.... Mine was supposed to but did not....
OK next is the Dyno runs, as you can see from the dyno chart the ECU's are so damn close after 6K that its negligible. We did several pulls in 2nd but there were traction issues, and all the pulls were within 3-4HP overall. BTW, we only ran his bike... He offered to put my bike up and run it also but frankly I only wanted to see ECU results, didn't want to turn this into what setup works best thread (besides if there was fueling left into my ECU it would not be a proper test).
In a nut shell, if I was going to get my ECU reflashed.... Ivan would get my business at this point. Ivan's bike with his flash, map & pipe felt seamless from way low to way up high. If any of the other ECU guys feel up for a comparison I would be willing to do this again with all 3 or 4. Just as a point of reference, Ivan's flash is DIFFERENT than the one Guhl sells and Brock sells so you need to go through Ivan to get this.... If you send your flash to Guhl, you're going to get A Guhl flash, not Ivan's.
