Meanwhile a real reflash of the stock ECU is actually modifying the basemaps themselves instead of altering signals to the ECU like the piggy backs do. Being a Bosch ME9 based unit this is far from a simple ECU, so I would be hesitant to half ass it on this. The Brentuning solution is much more involved than just a Power Commander which is really only modifying a few variables to extract as much HP from the bike as it can without really thoroughly remapping the ECU. While I have not used a Power Commander on this bike, I have had them on other bikes I've owned. And youre not gonna find one of these engines on ebay for $1k like a busa or GSXR. If you blow a motor, there will be no warranty coverage. Personally, Id be leary about reflashing one of these things. My point is, get your gearing setup correctly to allow you to run say 195 mph, then make power improvements that will help the bike pull to redline with that gearing. Not the super thin 0w oil Brock's bikes run. However I am running 5w40 BMW oil and pump gas. I always heard about all these bikes making 190-195 with Brock pipes and tuning but. I started out with Brocks map and made 179, after we tuned it, we ended up here:Īnd yes, I was a little disappointed. The lumpy air fuel curve down below 6k is due to the throttle position restrictions the ECU has built into. The actual horse power curves always looked the same, only there was MORE power once we dialed it in. We spent many hours on the dyno playing with different air fuel ratios to see what it wanted. This is my dyno chart, notice how straight the air fuel curve is from 7k on? This bike made the most power at 13.0 afr. I'm working on the video, I'll post it up tonight when its done. I can not attest to the total accuracy of the phone gps/speed pro app, but I assume its pretty accurate if you allow it to "catch up". I have found this to be pretty accurate but it does have a delayed reading, thats why I kept it on the rev limiter so long so I could make sure the phone gps captured the speed. When I went to make my top speed run, my Garmin GPS lost signal in that area for some reason, so I had to use my phone's GPS and the Speed Pro app. I can't see a -1 sprocket killing 15-16mph off the top speed.Īs far as speedo error, using my Garmin gps (in the pics I posted on page 2), my speedo was reading 70 mph and GPS was 67.5 mph, so 2.5 mph off at 70. Quite a few people here at the forum claim to have gone 191-192 on gps with stock gearing, not sure how seeing what my bike ran with only -1 on the front but. I'm running the 190/55/17 that has about 60% life left.(has 3k miles on it). Mathematically its not even possible unless they have a taller tire. So how people are getting 190 mph with stock gearing I have no clue. Based off of my math and what it ran today with 16/45 gears, I think it will go 186.5 mph with stock 17/45 gearing. This is obviously all she has with 16/45 gearing and a 14,200 limiter. It ran to the 14,200 limiter in probably 3/4 mile with the 16 tooth front sprocket. Pretty much confirmed there is no "top speed" limiter or restriction on my bike. I just don't think there is much peak hp to be gained with one, especially on a bike that is properly mapped already. Hell I know that if I could buy a tuner and gain even an honest 10 hp over my dyno tuned power commander setup, I'd buy one today. UNLESS they add timing advance in the upper range. I can see the power gain potential down low and midrange due to the throttle position restriction in the ECU until 9000, as far as top end power, I don't see how the flashes/tuners are really gonna add power over a dialed in Power Commander. I am also curious about the Flashes/tuners. I figure it will run 180 mph (GPS) at 14,200 with -1. I made a quick hit on mine a couple weeks ago and saw 178 mph (speedo so its high) at 13,800 and that's with -1 up front. They are geared to go 190-192 ish with 17/45. I would think these things should run 185 mph fairly easy in decent conditions. You must have been running into a good head wind. Jimmy you running stock gearing? I would think you should have ran faster the 177 mph.
