A long time ago..

I purchased the Myecu and installed it in my Centauro bike. at the time it was experiencing backfire which I thought would be resolved by implementing a new ECU (the original ECU is not fried, and is still operational to this day). (this should be somewhere 2016 ish timeframe).

Meanwhile I've overcome some relational issues and find my self staring at my V10 wanting it to get humming the way it should.

So.. these are the things I have done to the bike;
- KN filters (stock airhousing removed)
- Mistral crossover
- O2 sensor (wideband)
- New exhaust valves (suffered heat damage) and seats

I have started out on the instructions that cliff posted on the website;
- Disengaged o2 sensor.
- Sport map (stock)
- App on the phone
- setup the "starting voltage" on the TPS (96)

I have done several experiments but am not "content". The bike is starting poorly (it starts nice on the stock Ecu). I have not tried to drive it (i have several other bikes that can get me around).

As "sorting the Start" is basically the first step to getting anywhere, i would like to focus on that.

Basic map used
As said, i Launched off of the Sport 1100 map, which is operating on the same ECU (originally) as the V10.

behaviour when cold @10-15 celsius
The bike will start (after turning over some revolutions) and requires throttle input to keep going. Its smelling of fuel, so fuel is not short.

I have Used colourtune (transparant spark plug) to establish if there is any difference between the two cilinders and there is. The Right hand cilinder is more orange (rich) than the left hand cilinder (lean-er).

This seems to be more or less equal with the Stock ECU.

So.. how to proceed?
Should I

• - Change ignition
  - Change fuel

Where i could, in case of fuel tackle the obvious;
- level the fuel injection first (through the offset map, it states the 2nd cilinder is offset vs the first.. but is Right hand side the 1st?)

Hi Cliff,

Thanx for the quick response.

Got it, so..

1st step, get the engine up to temperature, where it should remain at idle on its own. This should be achieved at low end operating temp of 50C.

Checking into the maps I note that this temperature is also the level at which no fuel boost is given anymore.

I will check on this.

Minor complicating factor
Although my phone (i use an old Google Nexus 5 - my recent Honor 10 fails to connect) does seem to connect frequently, it occasionally fails to connect. This is frustrating when trying to get results. Next to this, the screen (when not touched) goes dark (power saving feature) which is also very annoying. 

I would like to switch to a wired connection and a laptop. The laptop doesnt power down its screen (i know where this setting is in the laptop, i have not found a similar setting on android). So monitoring what happens is easier. Perhaps logging etc is also somewhat more practical.

I have seen your response to Matieu which suggest  USB type of connection. I am unsure wether i should source the same type of cable.

I have seen the pages on the comms protocol, I am however completely coding illiterate, so should any software be available i would gladly use that.  (reviewing the protocol page leads me to believe that i would most likely be served with a usb-serial converter with some "wires" specifically patching into a patch cable from the serial end of the USB converter).

Glad to be hearing from u!

First of, a happy new year to you all.

The suggestion of the interfering Bluetooth connection seems interesting, as it happened to be that both devices were in my garage at the time.. I was oblivious of this particular possibility.

I will test this again, but that will be tomorrow earliest as today I will be doing the (obligatory) family visits!

The log files are created in the same directory as the maps. I use a program called Ghost Commander to navigate my devices.
A new log file is always created. Have you allowed permissions to write files? Can you save maps from the ECU?

The last section of https://www.myecu.biz/MyECU/FirstSteps.htm gives some guidence on starts.

Given you mentioned smelling fuel I suggest something like



I may of got carried away with the cold compensation. I'm in Australia, cold, we've heard of it.
