The boost trace is nice and level, indicating the wastegate is working well at 1 bar. If you need a lower pressure you need a lower pressure wastegate actuator for your turbo. I use a Kinagawa actuator that I can use different springs to achieve different boost pressures.
I plan to fully open the wastegate (disconnect the actuator rod) and make some logs...and try to tune NA. Then I try with softer spring that I have...but I'm not optimistic. This is second gear and I have 1 bar in the middle of RPM band with only 40% throttle....what will happens at 5-th or 6-th gear
Turbo is also to small, imo. But this waunt cause boost creep. Further a stiff spring or in most cases a to small WG hole. For check I would remove the WG actuator and make a testdrive with fully open WG. F.e. with enlarged WG hole up to 27mm and open WG my bandit made boost of 0.6 bar at higher rpm
Yep, I done it last evening. I find terrible lean spot between 2-5000 rpm...I fix it...and I'll try some changes under boost. The scary part is, that I haven't ride big bikes since 2007 and even NA Gixxer, fell to me like rocket. I plan to dyno da bike next month and most probably to sell it...I'm to old and too scared for this shit
The FPR body (if you look close to second pic) is made by me too....and most important is that the ports are switched , so you can have one more, of a lot of round 'things' on this side of bike. And some random pictures of new intake....and I still have no tail...I can't still choose.
The rule that found and used is 0.3 deg retard for each psi of boost. So your values at 200kpa should all end up 5 deg less than your 100kpa values. And you probably want all your advance in a bit sooner. The manual for my slabby engine said full advance by 2350rpm, so I would at least get all your in by 3500rpm at the latest.
Its a very safe and very conservative map - I had a look at mine but with 3 or 4 different compensations added it wouldn't make much sense but min is mapped to over 2 bar and is still getting a base timing of 28 degrees @ 9000 up which probably gets pulled down to 25-26? You could make the resolution off boost a bit more course to add lines under boost where you need them and i'd pump up some of your low rpm / low boost numbers - its more NA here so give it some timing!
