Harness is the same the base map will need to be updated to the specific bike model
Well, I've possibly got an issue with my Rapid Bike module.
I've done around 400 miles since fitting the module. Initially all was good, however I started to develop a flat spot between 6-8K which seems to be getting worse.
Looked at the auto tuning map and cylinder 1 is pretty much all positive values (maxed out in lots of places) and cylinder 2 pretty much all negative values (maxed out in lots of places too). It's almost like the two maps are polar opposites, with most of the peaks and troughs occurring at the rev range I'm experiencing issues with.
I've also noticed that my 02 sensors are reading different values when cold (0.81 and 0.61V) and this disparity continues when the engine is running.
I'm thinking that a have a dodgy 02 sensor and this is feeding the Rapid Bike module bad information and causing the flat spot.
Anyone got any other theories?
I have seen this identical issue - make sure you didn't reverse your O2 Sensor connections.
Erm.... checked today. They were reversed!!
Feel like such an idiot! I was having a couple of beers when I fitted it though.
Sorted the connections and then reset all the maps and took it out for a quick 200 miles!
I am now very happy. No flat spots, no CEL, just more midrange and improved throttle response!
Hello. i have the exact same problem and have turned the autotuning off because i am getting two completely different maps for each cylinder. Can someone help me with location of the o2 sensor plugs? I assume there is one for the horizontal and one for the vertical?
yes thats exactly what I have going on. i recently had my valve adjustment, and the exhaust shims all had to be changed. afterwards, we put it on the dyno (with the RB autotune on) and it was lean and the AF was off. I must also add that I have the Brentune flash, so my RB map table has been zeroed out until i can figure out whats going on with the autotuning...
That does not look right! Variance is normal, however not that drastic.
You can simply disconect either O2 Sensor and connect Rapidbike to a PC to see if the correct O2 Sensor corresponds to the O2 Sensor not reporting a value.
