It might be only in A mode (now quick-turn throttle mode), or it could have to do with the throttle cables being slightly loose, or maybe it's the extra torque the bike now has. I think about the same or maybe a little worse as stock. Sometimes on-off/ off-on throttle transitions are jerky since getting the ECU flash. I've seen it happen on a few other fz09's (with stock ECU) though. Fired right back up, but this fz09 has never done that before. Since the ECU flash the engine has randomly shut off on me while riding 2-3 times, at slow speeds, I think it only happened when I pulled in the clutch lever. It runs amazing but there are some things I'm curious about, and they could have to do with the bike itself not the ECU.

Since I am new and appears 6 months behind this chat, I would love to hear if any new information is out there.Have put around 200-300 miles on my bike (2017 fz) since installing the full Akra exhaust and getting the ECU back from vcyclenut. I will never run this beast WOT for any measurable distance. He said if you don't violate their RPM max warranty is valid. But my 350 has the rotordynamic flaw with the flywheel. I contacted local Nizpro dealer and he said does not void warranty, i believe he is mistaken. Next time I see him I will ask him if they will do the flash as well.

He purchased 15.75 x 13 pitch with the goal being plane on 2 engines.

He is complaining of the same slip issue. As fate would have it, my neighbors father just purchased 2014 360 Express with 3 x 300 v6. PowerTech has been very helpful and more technical than I expected. I have to go HP increase first and then reprop is my understanding. Current plan under review is buy 15.25 x 15 PowerTech 4 blade to gain rpm, and possibly the flash. Lots of slip in sloppy / somewhat large waves 6-8ft, but it is all anyone can do to get this on plane in 5ft following sea.

Back to the point, my props are salt water series II 16.25 x 17. Lucky me, got to purchase a new LH lower unit during covid. I cannot explain the degradation as hull is clean, engines sound/check good and only 500hrs on powerhead. I too only got 5400 rpm at survey, and now 5200. Gives the owners a 50/75/100 hp dial on the dash board. Additionally, I have a good friend that runs V10 Mercs on his Yellowfin, but for many years he as done this on Duramax diesels. I have raised the question do they consider local operating conditions and regionally they have different maps? S.Fl is completely different than Boston. Like others have stated simple fuel/air modification.

The download can be done DIY, I think but don't trust me. My neighbor turned me onto Nixpro as his friends did the flash on their 300s (engine details I do not know) they were happy. Don't forget the tune will require higher octane over 87.Ĭhrisk, I am new to the forum and investigating Nizpro. A tuner can play with those maps to get more power at the expense of what typically is more NOx emissions, especially if you are tuning a 4.2 to out muscle an f300. Keep in mind the factory ECU mapping is engineered for performance, but also emissions. Just because the rev limit is raised doesn't mean you need to run your engine that high. Will it hurt the engine if you did? Probably not if the engine is well maintained. The f300 will gain some power in the midrange, but the peak numbers are only achieved near the higher rev limiter.Īs for the risk, I wouldn't want to run any large outboard for long periods of time at WOT, let alone at a higher rev limit than what the factory did. As stated by another member, the 4.2 225 and 250 will benefit the most.

With Nizpro they raise the rev limiter several hundred rpm's while also tuning for more power across the entire rev range. ECU fuel and ignition mapping are the only differences.

The 4.2 f250 is the same engine as the f300.
