The MyECU thread

[luhbo]

You could put row one to 800 or so to avoid this (personally never had a problem with kick back). Then put its ignition advance to 20° for instance and you'll have some nice idle stabilisation. Nevertheless, transition from cranking to running may become tricky this way.

Besides that, this is page 8 now, there should not be too many questions left about what makes the text in the map.

Duc 900ie has 1000RPM/10 degrees in first row so there are some variations.

 

Anyway, thx f info, just wanted to clear this bit up f me & maybe other newbies.

We are among other things trying to create a How To/FAQ/more explicit manual here.

I've had kick back with mine from day one, if the battery isn't 100% I can't start the bike, but it starts fine with the old ECU !

I tried changing the Advance values etc with some success but I've not found a complete cure...yet

I suspect it may be as much to do with the cold start enrichment as anything but finding the solution is proving difficult, I suspect the 500 and 1000 columns may need attention, I'm using the injection and timing values from the 1100 sporti map that Raz posted and so far starting does appear improved but we'll see....

This is the map currently on my bike.

Just a comparison, from my OEM 907 ign map, 1st vertical row TPS, 1200 ideal idle:

 

600 799 1000 1199

 

0 3 12 10 10

1 3 12 10 10

3 3 12 11 11

4 3 12 11 12

8 3 14 14 14

11 3 14 14 16

 

It do start easily w that. So there row 600 f is starting & 799 f stabilizing idle? Lower than 800RPM it just wont run.

0 row, 42 max advance WOT etc makes this an unusual map indeed.

Maybe 3-5 degrees in row 500 is good f starting?

 

Quite different fr the 900ie OEM:

 

1000 1200
 
2,6 10 8
3,2 10 8
4,0 10 8
5,0 10 11
6,0 10 12
7,2 10 12
9,5 12 12
11,9 12 12

Cranking advance: 10 degrees.

My16M Config RPM=8223, O2=0.00V,-2.25V,-2.15V,-2.05V,-1.96V,-1.86V,-1.76V,-1.66V, TPS=103 TDCWhileCranking=0 AnalogTracking=1

 

You should try

 

TDCWhileCranking=1

 

if you haven't already.

 

When did you get your My15M? There have been some improvements made to improve low battery conditions. Some may apply to yours.

I've just changed the TDC setting to off recently to see what effect it had having noticed that the 1100 Sporti map that Raz posted was set up this way(I'm also using the injection and timing values),I need to let the battery discharge a little to be sure but it did seem better, but I suspect as the battery was fully charged it may not be the case.

I've had the ECU approx 2yrs so I assume its reasonably up to date?

Send me a high res pic from this location (no connector in my shot)

 

I think a lot of the newer bikes seem to have a constant load on the battery. If it is not ridden daily you should put in on a charger before starting.

The best my camera will do,hope its ok.

Tip I got:

 

# Cliff now uses coilcharge1=2700

MyECU Cfg CoilCharge0=6000,CoilCharge1=2500

 

Is this true for most of us, both MyP8 & My 15/16M owners?

I guess you're thinking of Nigel's map (which I posted). FWIW I have always used TDCWhileCranking=1.

If I understand it right, a higher number is better (more powerful spark) but will put more stress on the coil, and a too high number may destroy it. I wonder how one could try out a higher number. Measuring temperature of coil after some running at high rpm? Or does the coil manufacturer specify a limit?

Its the FET that is the weak link. I let the MyP8 driver longer because it has external boosters.

[raz]

So assuming 2,700 µs is short enough not to cook stuff even at sustained near-redline speeds, we could in theory use 5,400 µs at 4,000 rpm or 10,800 µs at 2,000 rpm with the same need for power dissipation. Would that be of any benefit?

 

Also, we could use 20,000 µs or more for cranking (my map use 6,000) with less stress [over time] than the above, but that is probably way beyond the point there is more pain than gain. And the power is drawn from the battery while cranking...

 

Just thinking loud. I don't think I'm on to something

[luhbo]

.... I don't think I'm on to something

 

Probably not, yes. It only takes a certain time to get a coil completely charged, more than that is useless.

The coils are 0.7ohm so at 14V the will run to 20A. This is 2x what the FET will take continuous. So there's a maximum time before the

FET current rating is exceeded and the FETs have a burst current rating.

 

I prefer to err on the lowest setting.
