![]() Ivan’s flash fixes issues that the PC can not fix. I had a PCFC (power commander) installed since about 5000 miles or so. I have logged about 475 miles with Ivan’s ECU flash. I have Ivan’s Gen 2 reflash installed in my 2010 FJR. This is definitely one of the better performance upgrades you can do for the Gen II FJR. With my frankentank I now have a legit 450 mile fuel range. (It was in the mid-30's 2up without the trailer, and 28-30 with the trailer). Mileage an impressive 46.9 MPG two up and screwing around on the throttle. ![]() I can live with that for the performance gains. ![]() With the performance comes a cost, the bike runs at 5 bars temp now, where it was running at 4 bars before. I will have to adjust how I ride the bike It put the sport back into my Gen II. There is no lag in power delivery as you roll on the throttle, you start moving forward now. He described as the file size for the ECU is 100K, where the Gen III is 1.1M He said with the Gen III he can tune many more parameters as a result. In talking with Ivan, he said the Gen II has very limited parameters that he can change. The power delivery was amazing, this is what the bike should be like. Extremely impressive, no valve knock, now hesitation, nothing wasted, just forward momentum. The bike took any throttle input and built power, speed and RPM almost in a linear fashion. Everything you want it to be, but Yamaha didn't deliver. No surging in the bike, no closed throttle bucking, no throttle lag when rolling on, no surge. I intentionally did many roll ons from very low RPM in 5th gear. If Yamaha had put a tune like this in the bikes from the factory, you would not need all the work arounds that the Gen II suffered from. Not a violent power hit, just a power delivery with a purpose (if that makes sense). The power was smooth at all RPMs, and gears. The power delivery is as smooth as my race bikes were back in the day. I shift without using the clutch on upshifts by slightly letting off the throttle to unload the transmission and clicking up to the next gear. Mrs AuburnFJR's first comment was how smooth it runs and smooth it shifts. I filled the bike up so I could check mileage when I got back. I went for a 100 mile two up ride without the trailer. Here is the plug removed (and you can see I have tons of extra wires on my bike for all the farkles.)įirst Impressions: (Conditions - 2 up, full tank - premium, remus exhaust with the cores in, PAIR removed, V Stream windscreen fully up, 80+ degrees, headed to the mountains) You'll need to remove the tank and the side cover on the left side to access the ECU. (My first ride impressions are at the bottom of the post) It took as long to remove and replace the O2 sensor as it did to do the everything else, probably 1 hour total as we were taking pictures for this. (Acutally he changed the ECU, while I removed the PC V and Autotune and reinstalled the stock O2 sensor). ![]() Jay came over and helped me change out the ECU. He shipped it back to me 2nd day air and I had it in my hands that Friday afternoon. I sent it in on a Monday afternoon (2nd day air) and he called me Wednesday afternoon to confirm details and to process payment. He changed his out a few weeks ago at my house and then gave me his ECU to send n for the reflash. He actually bought the ECU that Ivan used as his test mule to develop the tune. Redneck J had been talking with Ivan for some time now and had his reflashed a few weeks ago. I recently had my ECU reflashed by Ivan's Performance Products.
