The MyECU thread

gavo · August 27, 2008

Brilliant, just what is needed a thread to bring all the MyEcu material together.

For interest it would be good to know those who have built up their units from Cliff's kit. I have started the My15m now and done the easy bit - the adapter board. Next on the list is the Optimiser but that will not commence for a couple of weeks due to time constraints. If anyone is interested I can post some pics and comments on construction by a relatively inexperienced individual, who is looking forward to the learning process.

I for one would like to see some pic's and comments on constuction. I,ve made up my mind to buy this unit but can't decide on kit or completed unit so please post

Take a look at the pictures and describtion from my assembly of the My16M.

Assembly of the My16M - link to Guzzitech.dk

Please note that the pictures are from the assembly of the Mk1 edition where you have to connect the WM connector to the PC board with 35 single wires. Not an easy task - especially when you want the entire setup to look nice.

I just finished building the current Mk III where the WM connector goes directly into the PC board. The Mk III is much easier to build and will probably have better long term stability due to improved mechanical stability (Not that I had any issues with the Mk1)

Bottom line is that I have been running the My16M for +10.000 kms including a 4000 km trip to Mandello last year. 100 % stable and reliable. Even a 1000 km weekend trip in pouring rain could not disturb it.

I really love the My16M concept and I have even better control of mixture and ignition than I had with my old Le Mans (40mm Dell Orto's and Moto Witt ignition)

And the closed loop operation is simply awesome - we went over the Stelvio pass on the Italy trip, and even at 2800 meters above sea level the bike was as crisp and clean running as ever. Thats not possible with a carb /open loop injection bike.

Go for it.

Your writeup is excellent Jens, I recall it was your story that made me buy one. I haven't seen anything like that on a My15M build so don't forget taking pics, John!

Jens, are you just 'upgrading' or do you have another bike now? I asked Cliff long ago if I could buy a Mk III circuit board, for upgrading mine, but he never answered. The Mk III apparently has circuitry that helps out if the voltage drops during cranking.

Speaking of PCB's, I've stumbled over this picture on the 'net:

What on earth is that? It's not a Mk I, it's older than Mk II but the PCB looks better, multilayer with lots of ground plane and using the existing heat sinks. It must be a Mk one-and-a-half prototype?

If its useful to anyone this is my map with Raz's suggested changes added, but I've not tested it yet !!!

So as I said before this map is work in progress (but is getting closer :lol: )

Just FYI:

MyECU tested on 907IE, Cagiva 900ie & ST4engine Ducatis.

Works good. Some work w translating Guzzi maps to Ducs. Test w P8/888 soon.

I managed to get out for a ride last night, running closed loop has made the map leaner almost everywhere (at high rpm I often see -25% correction being applied on the display while running closed loop but most of the time its 12% or less and some midrange areas are now showing 0 % ).
The problems I need to look at are now lots of popping on the overrun and an off idle flatspot in the low/midrange ,I can't blip the throttle on down changes and there is a loss of power when gently opening the throttle, these are all most likely related to the targets I am now using so I'll play around with these areas.

The display shows some of the areas running 25%+ rich as 6a 7a 8a (the only ones I could read while riding anyway) which I assume are hexdecimal grid reference points to the map (6 7 and 8 changed with throttle position so 'a' must be RPM ?), so some manual editing of the map will have to be tried there because its not possible to hold the break points for long enough.

Please insert your maps in codeboxes so the format doesn't screw up!

You did a big change to the target map so until the injection map settles it will be a little rough when moving between cells that are corrected and ones that are not. It doesn't take long though. Maybe you should wait until it's settled before you try to fine tune it.

Like you said, (6,a) means (6,10) and they are (throttle,rpm). I usually don't aim much for the breakpoints, I just ride with autotune active. Over this summer almost every cell has settled anyway. Normal riding involves surprisingly few cells and these will correct themselves very quick.

Are the popping at row 0 only? Maybe you should run that whole row at open loop again and reset its' pulse-widths to what it was before.

Oh, and another thing: have you checked that you don't have a ground offset? When I first read the digital channel into my laptop, I realized my analog was offset about 20 mV. To compensate for that I altered the outputs accoringly so the ECU reads the same as the computer does.

A larger ground offset than that could theoretically make your mixture much leaner than intented, and at these pretty lean levels that can be a bit of a risk.

Jens, are you just 'upgrading' or do you have another bike now? I asked Cliff long ago if I could buy a Mk III circuit board, for upgrading mine, but he never answered. The Mk III apparently has circuitry that helps out if the voltage drops during cranking.

Bike is the same - the Sporti is a keeper for sure

I'm not actually upgrading, but I decided to build a Mk III from scratch.

Main reason is that I want to have a spare MyECU around if the box on the bike should ever fail. I still have the original WM ECU lying somewhere in my workshop, but I have no desire to put it back on the bike again - ever. The My16M is that good.

Another thing is that I really like the improved mechanical stability of the Mk III layout (I've always been a bit worried about the 35 wires in the box. I never had any problems with them, so it's probably just a mind thing.....)

My Mk1 is upgraded to the newest firmware version, so maps are directly interchangeable. I find it quite amazing that all sensors including tps are showing exactly the same values on both ECU's which means that I can move a map from one unit to another without any corrections at all.

I did about 90 miles last night so the map may be as settled as its going to get ,my friend was riding behind and said he could smell the unburnt fuel so I'm pretty sure there are areas of the map that are still too rich, but by the time I got home the low midrange was really good (your tighter rpm columns work well) and the only issues I had were the over run popping and the off closed throttle flatspot which may well be related to the new row 0 targets(before it used to blow back through the throttle bodies when blipped )

I realized quite early on that aiming for the breakpoints is nigh on impossible and have been doing as you said just riding and letting it work out itself, only if I see the MON in the display do I attempt to hold it for the 5 seconds required (it seems like an awful long time )

For anyone trying this I recommend that you copy the map from the ECU before and after every closed loop ride then compare them , this also means you can restore the ECU if it gets worse not better (I also keep copies of my maps, dated and named, in several locations just in case... )

Oh, and another thing: have you checked that you don't have a ground offset? When I first read the digital channel into my laptop, I realized my analog was offset about 20 mV. To compensate for that I altered the outputs accoringly so the ECU reads the same as the computer does.

A larger ground offset than that could theoretically make your mixture much leaner than intented, and at these pretty lean levels that can be a bit of a risk.

I'm sure the ground for LC-1 is the same as for the ECU (I remember making sure I did this during the install) but I will double check this :thumbsup: ,

also can you please clarify what you mean by reading the Digital Channel on the Laptop and comparing it to the Analog.

My understanding of this would be that you are comparing the LC-1's software reading with the ECU's reading in the ECUcontroller application, is that right ? :huh2:

Yes I do that too so I can see the progress. I have a pretty good perl script that shows the difference between two rides. This is an example output from your maps:

My grounds are made carefully and correctly too but there still was a little offset. What I mean is you can connect a laptop to the LC-1 serial cable (the 2.5 mm stereo plug to a RS232 computer serial) and read the digital out using the LogWorks software. This will not be affected by any grounding issues, you can trust it as long as you did a free air calibration by the book. At the same time you read the voltage displayed in the Optimiser. If there is any discrepancy you have a grounding issue and you can correct it by altering the output specs accordingly.

IIRC I even set the LC-1 to always output 1.0 volts, checked against Optimiser (which read 1.02 V), then set it to always output 4 volts and checked again (now reading 4.02 V). This showed that I had a fixed offset of 0.02 volts. So I just adjusted the analog outputs by the same amount.

This is only important when we share maps. If you would have a large offset but work out your own sane voltages you'd be fine anyway but your data would not be useful for others unless we know our voltages mean the same.

If you would have an offset of -0.1 volts (which is not very likely if you follow the instructions) and just copy my O2 targets, you would run at 0.02 leaner Lambda all over. I.e. 0.98 instead of 0.96, that could be bad.

Can the MyECU handle 2 WB sensors??

Can the MyECU handle 2 WB sensors?? ...

Of course. And the optimiser should be able to autotune the offset map as well. Ask Cliff for details.

This line makes the switch: "MyECU Cfg 2ndO2Sensor=no" (Write YES instead)

I got My15m up and running. Everything works fine, optimizer etc. I tried to use a usb 2 serial adaptor to connect to my laptop but no communication was ever established. Yes I have the driver installed and under the assumption that the usb 2 serial cable works, it is brand new. I can communicate with the ECU using an older computer with a serial connection, so the serial interface is good. Anyone here sucessfully use a usb 2 serial and am I missing something simple.

I have had various problems with my usb-to-serial and it ended up being stupid synch programs for PDA's and such (like Microsoft ActiveSync), that steals the com ports. Now I quit all such programs before running ECUControl.
