Alright, so I recently installed an FTECU harness and tried to flash their unrestricted image on my bike and afterwards it would not start. It would turn over and then just die. Freaking out I immediately reflashed the stock file but then was welcomed by many error codes and a check engine light. This is where I should mention that my bike is used and the gentleman that owned it before me seems to have had a quick shifter installed. I am now wondering if he had the ECU flashed, there was no sticker on it so I assumed it was the stock image. So, after running diagnostics through the harness the following things failed:
P0030 HO2S Heater Control Circuit (Bank 1 Sensor 1)
P0050 HO2S Heater Control Circuit (Bank 2 Sensor 1)
P0476 Exhaust Pressure Control Valve Malfunction
P048D Exhaust Pressure Control Valve Position Sensor/Switch Circuit Low
P062F Generic Internal Control Module EEPROM Error
P1400 Cold Start Emission Reduction Control System
The exhaust I was told from the dealership was messed with by removing the silencer (maybe more?) by the previous owner in order to liven up the sound and it is louder than what I would think a stock exhaust should be. But I just wanted to make sure that none of these codes are red flags that I should be concerned about. Hopefully I'll be able to contribute better things than tons of questions in the future!
Thanks for making it this far if you did!

The only one there that concerns me is P062F. Here is info from the workshop manual regarding that code....
Code
P062F
Description
EEPROM fault code number (an error is detected while read- ing or writing on EEPROM)
Probable Cause
• CO adjustment value is not properly written.
• ISC learning value is not properly written.
• OBD memory value
is not properly writ-
ten.
• Malfunction in ECU.
Symptoms
Increased exhaust emissions.
Engine cannot be started or is difficult to start.
Engine idling speed is unstable.
OBD memory value is not correct.
Fail Safe Operation
CO adjustment value for the faulty cylinder = 0 (default value) ISC learning values = Default values
OBD memory value is initialized. Initialization of O2 feedback learning value.
Cruise control system cannot be operated.
First thing to do is clear all error codes...do they come back? If not, all good, possibly just the ECU throwing a bit of a fit after the flash, of it comes back you need to take it to be looked at professionally.

So I did some digging into FTECU's "Unrestricted" images and under the diagnostics manager they have that code disabled on the list of DTC codes so maybe there is a possibility of it being thrown when flashing? Also I appreciate the info on the code itself! Was it found from the owners manual? |

That info came from the Workshop manual, the one used by Yamaha Dealerships, not the owners manual that came with the bike. Like you say, it might just be a result of doing a flash, but first thing to do now is to clear all the error codes with a diagnostic device and see if they come back or if they stay cleared.
If you clear them and they do not come back then take the bike for a test ride and check if cruise control works. It seems that nearly every single error code mentioned above will disable cruise control, so if it works on the test ride then you can be pretty confident that there are no faults and the bike is in good health.
However if that does not work, then you'll likely need a professional tuning company to look at it and see what needs to be done.

Update: I found paperwork under the seat that had the original owners phone number on it and hit him up. He told me he disconnected both O2 sensors, the exhaust valves and the AIS and also got the ECU flashed by Nels. So this explains the CEL but now I still have an issue of where the bike only sometimes wants to start after flashing it. It seems to be a problem with the ground because after messing with it, it will sometimes start and preform fine. But I just don’t understand what’s wrong with the wiring...
It’s just becoming a large headache now because everything looks perfectly fine to me.

Somethings to check are all the pins in the multi-pin ECU connectors. All it takes is one bent to throw several codes and cause many problems. A strong flashlight and a small magnifying glass helps.
Good luck,

I doubt anything is bent. Seems to me that most of the errors relate to things being unplugged by the previous owner (O2 sensor, EXUP valve, etc) and the ECU error might be something linked to the flashing back and forth.
Honestly not sure exactly what logic these ECU's use and there may be something in them that throws up P062F when flashed outwith the official Yamaha system, hence mappers are disabling that code as the OP found with the FTECU map.
My advice, take it back to NELs, where the previous owner had it mapped and get them to put the map that was on there back onto the ECU, take you right back to your starting point.
Once you have done that you SHOULD be back to square 1 and the bike should work as it did previously. Or, if you are unhappy with how the bike was before (hence you went to put on a map which caused all these issues) take it to a company you trust and get them to map it from scratch and sort the ECU faults while there.
All this now seems like it boils down to the fact the previous owner has removed a few things that the stock ECU map is not happy with and needs a remap to sort it.

SO hopefully this is the last update! I was able to get the bike properly working again and being able to flash whatever I wanted on it! There is a ground wire on the harness that refused to make a good connection so I ended up just soldering the two together. I appreciate all your guys help many of you helped my thought process to actually be able to get it working again!
Thanks again!

I have an error message coming when the bike is cold but goes away when hot. So it feels like it's possible ground problem. Thanks |
