You changed the TPS?

Great thread. Going to switch back to the OEM plugs next service.

Very nice setup with the laser tool.

Here in the motorcycle state of Florida, I get waves from everyone with a few exceptions. I'll get waves from 1 out of 10 Harley riders. About 1 out of 5 for BMW riders. Guys riding Japanese cruisers wave all the time. When I get the Harley waves, it usually catches me off guard.

Glad you're ok. Good keeping her under control.

Link?

I've seen five other than mine here in northeast Florida. But I'm in Harley country for sure.

Rustled Jimmies. I want to change my user name to that. LOL

I had it flashed by Vcyclenut. The flash was great for engine decel, speed limiter, and general smoothness. Unfortunately there is almost like a dead spot until you have an 1/8 inch of throttle in. Very abrupt like a light switch. That's why I checked the resistance on the APS/TPS. I've already talked to Dave and will probably send the ECU back for reflash. It may just be my bike.

Just an update. After I adjusted my 2017 using the OBD2 tool, I set it back to the original settings as I previously posted. I pulled all the connectors in the YCC-T system, inspected for corrosion and installed dielectric grease in the connectors. I used this video and the manual to check resistances which were good. I was specifically looking for dead spots or resistance spikes in the sensors. After that I did a throttle body sync, replaced the air filter, and adjusted the chain. The bike runs much better now with the abruptness being barely noticeable. I believe the only way to get rid of it is to reflash the ECU with custom settings or sell the bike lol. I did ride it with TCS off and didn't notice any difference in the throttle.

We don't have the amount of bike theft other countries do. That's my guess for not having an immobilizer. I don't think I've even seen one on any brand in the US except Harley. Back on topic, I wonder if a 17 ECU from an FZ, MT, or XSR would work? Same engine.

I have one and I personally think it's fantastic. Just the flash modes alone make this worth every penny but I really hated the OEM not lighting up all the way in running mode. I see what you are saying about brightness but I think the flash modes will overcome your concerns.

Voice. I had to look twice once you started talkiing. If Rowe retires, you're a shoe in.

Whoah!, Mike Rowe owns an FJ? Lol.

No. I'm going to try it . Thanks.

I hear you. I've had the bike for two years. I've learned to live with this. It's very specific. Basically, after the initial slack is taken out of the throttle (I have it set to the minimum by the manual), there is no fuel until about an eighth of an inch of throttle. Then it hits. It hits harder then I like. I have test driven three other brand new FI motorcycles and none do this. I made a graph to show Dave so he'll understand what I'm talking about. Green is what I want. Red is what it's doing.

I've already contacted him. I wanted to try this before sending the ECU back. He seems like a great guy.

I'm updating this thread for the sake of science. I have a 2017. I'm experiencing snatchy throttle after my ECU flash. It's driving me nuts. I bought an ODB II patch cable for the bike so I could hook up my ODB II dongle. Since I couldn't go into the diagnostic mode on the bike, I checked the throttle position indications on my app. They matched what people had set their FJs to in this thread and I noticed that the white line on the APS was straight across. So in my opinion, the 2017s were set at the lower numbers at the factory and that's why the diagnostic modes were removed. (Totally uneducated guess). I decided to adjust it anyway. The two throttle positions were 14% and 13% as shown in the pic. I put the closed throttle at 10%. No good. Snatchiness went away but the idle shot up to 2500 rpm and the exhaust started to glow red. Oops. Adjusted to 12%. Idle was better but still a little high. Set both at 13%. Back to the original setting. Runs great. Snatchiness is still there but I think it may be the flash. Got it done by Vcyclenut. So there you have it. 2017s do not seem to have any adjustment left to mess with. Below are the pics of my setup.

Well crap. Now you tell me.

This forum is fantastic. It is a wealth of knowledge. So it looks different than before. Want memes? Go to Facebook.

What bike is this?

Yeeeesssss!!!!! Can't wait.

I had my FJ a week and a girl almost t-boned me in a gas station parking lot at night. I have Hiviz gear with highly reflective stuff all over it. Ended up putting Custom Dynamics red and amber Magic Spot LEDS on the sides of the bike. Super bright at night. No problems since.

I'm going to try this on my 17. I won't have any numbers to go by so It's going to be a trial and error thing. I'm going to mark the current position so I can go back to it if I have to. I'll post results. Actually, I should get an ODB II cable since I have a reader. That would probably be the smart thing before I try it.
