![]() ![]() This is why i think it is reasonable that i now have 300 hp. ![]() ![]() the 200 one did 45 knots and the 250 one did 54. I do not know that i have 300 hp, but with the old ecu, the boat did 51 knots, and with the new one it did 59, and i have owned 2 boats with basicly the same hull with 200 and 250 before. They told us that the weight and torque of this setup would be ok, but if you push it to the limit, the boat just wasnt made for the speed. They did not allow us to do this because the boat did over 60 knots and became very unstable. Yamaha YZF-R3 ECU Flash’s biggest improvement is actually in the midrange where you feel it driving off the. We had contact with the factory of the boats directly because we wanted the 350hp V8 outboard, and the factory did tests with it with the intention of finding out if it was possible. Raise rev limiter (this is critical for racing, as you can now shift above 12500k and stay in the power band) While this Yamaha YZF-R3 ECU Flash will definitely open up extra top end power along with the mid range power and torque. The prices for everything with a motor is INSANE in this contry.The dealer gave me full warranty.Īnother reason for not getting the 300 motor right away was that the boat manufacturer and dealer didnt want to sell this boat with this much horsepower, but the drunk dealer agreed to do the ecu swap as long as it had 225 stickers on it and we told noone. When i bought this engine, Norway had an HP tax of 120 usd per hp, and a year later the tax was removed, so i saw no drawback with this method. ![]() The reason i chose to do this ecu swap was that i had already bought the boat with the engine on it, and i was talking to a drunk dealer who told me that the 225, 250 and 300 versions at the time had all the same internals, and the only difference was the ecu. DO IT!!! Its super cheap horsepower plus a fuel saver.Will provide more exact model numbers when i get a chance, sorry for not being specific! I think i will recieve the new boat with the 2018 engine in a week or two, and we are going to change back to the 225 ecu on the 2011 one this weekend. That gives me 318 dynode horsepower from my 225. To gain the full benefits, I need to run 91 octane. it assumes fuel rail pressure and all its inputs are correct and reacts accordingly. Its already paid for itself in fuel savings, in 3 years. I talked to Eric for along time before doing it, because I heard of all the "bad things". Your rev limiter will be reset to allow a few hundred more RPM, but the RPM gains realized are from the enhancements. The old saying that a dealer will see the reflash, is completely untrue. That's an engine killer! You'll notice much better fuel economy, and hole shot, right off the bat. The exhaust temps actually go down, instead of up, which is usually seen when leaning out an engine. Also said to increase fuel economy and the rev limiter changes to 6400. The timing advance and curve is straightened. Does anyone have any experience with the Nizpro Marine ECU flashing for a Yamaha 250 sho It is supposed to increase your horsepower to 320 hp and increase your torque by 5. speed limiter removal powerful sangomas in mozambique 4f85 bmw steven dux spreadsheets comeback cut powder mmd bunnymarthy porn approved. The fuel injection pulses and trims are smoothened out, the air/fuel ratio is tightened up, because they run so fat from the factory. ![]()
