With MyECU, the engine will turn over, and fire intermittently, but won't run.  It fires best at zero throttle, and not at all at mid or full throttle.

Bike is a V7 Classic, warmed up first with the OEM ECU.  Note that engine has a big bore kit, bringing it to 820cc. 

Map is Cliff's Breva Map, which I downloaded from the forum.  I followed the instructions and adjusted the map's TPS to 106 (my bike's zero throttle reading), and then saved the map to the ECU.

Any ideas?

Not sure what map you downloaded but I sent you may current Breva map.

Did you check all the analogs are giving correct readings, especially the air pressure sensor.

Are you smelling much fuel?

I suggest adding 1 to each value on Prime line to see if that improves things. If it does add one more if required. You might want to added 10% to the "InjDur 00" line for at least the first 3 values.

How is the voltage booster working on the bike? If it is still not working it could be that voltage dips are resetting the processor. If you log the start you can see this.

Edit: I suggest using notepad for the changes at first. It is less error prone when starting.

Thanks for the new map.  I loaded it onto the ECU, and put in my TPS base (106).  I'm charging my bike's battery now, so I can start the process again tomorrow.

Here where my readings when I was trying to start:
O2        OilT   AirT   AirP     Throttle    Bat      O2(1)   O2(2)
2.48V    10c    10c  945MB    106        11.8V   2.48V   2.64V

The engine sounded like one cylinder was firing, or trying to, but not both.  I didn't smell fuel, but then I wasn't looking for it, and there was a lot of exhaust fumes. 

How can I log the start, and how can see if the voltage booster is working?

Success!  Thanks to the new Breva map from Cliff, the bike will run now.  I've started adjusting the TPS and inj duration at idle, as the instructions suggest.

Oddly, although it's a big bore 750cc (820cc) with an 9% enlargement, when I adjusted the idle inj duration, it came to slightly less than Cliff's stock Breva map.  Approx. 1.5% less.  I imagine it should have been 9% more, right?

In the adjustment process I didn't change the idle screw, but adjusted only the inj duration until I got the bike to idle at 1,100.  Reportedly the idle screw (really a butterfly stop screw) is a "sacred screw" set by the factory, not to be touched.  Does this sound correct?  Could this be why I'm not needing 9% more inj duration?

I'll try to log a start, to see what's happening with the voltage booster. 

Thanks again for the help!

Is that 945mB correct? For sea level it would be on the low side. Did you  select the appropriate Pressure sensor line for the map? Correcting this will make the map about 5% richer.
The battery voltage seems low. How does that compare with the actual value.
For the booster function just measure the voltage.
If it is starting ok then logging the start doesn't seem necessary now.

I am at 100 ft above sea level, or 1010 mB pressure.  So the 945 value is off.  The pressure sensor I salvaged had some issues; the top fell off and I fixed it with a spot of glue.  I hope it doesn't have problems.
How can I  "select the appropriate pressure sensor line for the map"?

The battery voltage is low, only because the bike's had a lot of starts. 

How do I measure the booster circuit voltage?   

1 - The OEM ECU uses 3 different pressure sensors. In your map file you
should change the presssure line with one of the following
MyECU Cfg Pressure=250mV,120mB,4200mV,1060mB
MyECU Cfg Pressure=250mV,120mB,3900mV,1060mB
MyECU Cfg Pressure=250mV,120mB,4750mV,1060mB

If you see 1024mB displayed it is probably invalid. One of the lines
should give you a sensible reading.

You can measure the booster voltage at the input pin of the voltage regulator.

My map had :
MyECU Cfg Pressure=249mV,120mB,4751mV,1060mB

Which I changed to:
MyECU Cfg Pressure=250mV,120mB,4200mV,1060mB

I'll test this new map later.

When you say that I can "measure the booster voltage at the input pin of the voltage regulator."  Do you mean at the  connector of the voltage regulator, up at the front of the bike?

Thank you for the help.  It'll be a day or two for me to respond, as I'm getting married today.  Once the relatives are gone and the bride is settle I can back to real fun - the bike.

A man with priorities that will now inevitably be changed - anyway congratulations!

Congratulations, safer to make your bride the priority though.

Congratulations on your marriage.

I'm talking about the voltage regulator inside the ECU. You've been measuring the voltage boost previously in the other thread. I don't understand your confusion now.

Cliff, thanks again for the new Breva map.  The bike is starting and idling very well.  I've sorted out the first steps, and will do test runs on the street.

Voltage booster - When connected to the bike, I'm getting 14.4 V, so that's good, right?  I'm glad that's working.

ECU Internals - Is it good to glue some of the ECU components down?  Why?  Should I do that?  I ask because in MyECU photos I see that this is sometimes done, and I want to increase the ECU's longevity.

Errata - As a gift to my brother (my best man at the wedding) I bought him a bottle of Johnny Walker Blue Label.  The price was crazy.  We sampled it, and it was very good, terrific, but not so much better than J. Walker's other fine labels. So save your $ and go red, black, or green.

Joe - try a Dalmore - it's made across the firth from me and is a fine dram. The Cigar malt is excellent if you can get it. Pop a bit into the injectors too if feeling particularly profligate! There are no bad whiskys - just that some are better than others...
