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. It makes a much better track bike anyway.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 eventually took my HP ECU equipped bike off the street. It can and will bite you if you don't respect it. The DTC system is re-tuned completely for performance rather than rider safety with the assumption that you know what you are doing. On the street you will find it's a bit of a handful and gets a lot hotter than a stock bike does. ![]() The Race ECU did not have a setting for this at all. For example when my bike was in it's street bodywork I needed to have the rate flash delay changed for my HP LED turn signals. The HP Race ECU has a few minor rough edges. But then again why would you be having an HP equipped bike serviced at a dealership not qualified to do it? Non BMW HP dealers often don't have correct information about what the warranty actually covers and does not cover and often deny claims because they don't know any better. I'm pretty confident BMW would do the right thing for me. Personally the warranty issues don't bother me at all. The ECU and RCK only affect the engine so all other warranty areas on the bike are normally not an issue at all. It does make certain warranty claims more challenging of course but that's where the relationship with the dealer comes in to play. An HP race ECU or an RCK being present does not automatically invalidate the warranty on the bike. It depends on your relationship with your dealer. I'm surprised nobody has offered up TC Rule #2, haul out your copies of Twist of the Wrist II and take a look! Here's a hint, it is in Chapter 6. Potentially you could damage the engine by messing around with timing of internal operations and understandably the factory might not want to replace an engine someone damaged by discarding the reliable factory tested values and substituting their own creative experiments using the RCK. The Race ECU and RCK kit allows you to fiddle with practically everything which is why the warranty becomes an issue. I am not sure if the PC-V will do roll-off. I do n't see how it would void the warranty as you can put the software back to stock if you wanted to. do you remember Throttle Control Rule #2? I think it would be a nice thing to add on to a sportbike, if it is affordable and can be done - did you check to see if it voids the warranty to re-flash the ECU? What does it cost? Doesn't a Power Commander with dyno tuning address the throttle response for both on roll on and roll off, or is it only for roll-on?Īs far as the throttle control rules go. Or, the Race ECU package allows you to get in and set ALL KINDS of parameters on throttle response and engine braking, tuning it exactly how you want it. It takes some getting used to, though, it feels a lot different. ![]() I know on the BMW S1000rr, the Slick mode changes throttle response and significantly reduces engine braking, which can help carry more speed into corners and reduce the effect of a jerky roll-off, I like riding in that mode as it definitely helps me roll into corners with more entry speed. Here's a video that covers all the HP options for the RR Teamed with the HP Datalogger you have all the data you need to make adjustments that will get the bike to do what you want. I can easily leave 2015+ models in the dust if I want to. ![]() I own a 2013 RR with the HP ECU and RCK2. The difference in DTC tuning alone is amazing. Tuning is accomplished with a Laptop connected via a cable to a port in the tail of the bike. The RCK allows adjustment on DTC, DDC, ABS, ECU and pretty much any other system on the bike. Most people go with the ECU and the RCK and the TI Akrapovic exhaust comes with the ECU. This gives you the adjust ability and as Hotfoot said you can adjust just about anything you want on the bike. The Race Calibration kit is an extra add on. You get full power in all modes and the mode selection no longer affects the engine map. The base maps for the Race ECU are pulled straight out of World Superbike. On the S10000RR the Race ECU completely transforms the bike. ![]()
