The MyECU thread

[emry]

For those of use that are verbally challenged. NOTE: timing and cam specs are not from our engines!!!!

[luhbo]

Well, I thought we start counting at 0°, valves both open, then 1 full circle, 360° (ignition), then finally at 520° the full load of fuel is supplied, 200° before the Otto-cycle starts again at 720/0 degrees.

 

That's not too challenging, or am I missing something? BTW, I think the other diagramm shows a similar flaw: 360° normaly is around ignition TDC, not at overlapping. Peanuts anyway...

PS: Emry, where do these curves come from? You could nearly post them in the Hooters thread Is it a Ducati Desmo chart?

 

2. PS: Sorry, looking closer at it I think it's not from any working engine at all. Not a good source I'm afraid.

We are (or I am) talking about how the MyECU handles InjAdv, regardless of what is more or less common notation.

 

This is what Cliff said again:

InjAdv is degrees before TDC that the Inj pulse ENDS.

...

300 is just before the inlet opens and is the logical place to inject fuel. I found the bike felt crisper.

600 is well before and roughly where the OEM injects.

It's a little confusing that he says 300 is before inlets opens, but I take it he must mean 0° is the TDC at ignition. And we are counting backwards, as in advance, so 360° is the overlap and 470° is when exhaust valves are max open. And 525° is even earlier, when exhaust valves are still opening.

 

As I read him, we can take MotoGuzznix' chart and just reverse the degree heading, so it starts with 720 and ends with 0.

 

Do you read it differently?

[emry]

I found Cliffs post a little confusing too. TDC?? Which one compression or overlap? If we back up from either of the TDC's 300 degrees we end up in the middle of our power stroke (too early) or the middle of our intake stroke (too late). Neither would be a good time to inject.

I agree.

The chart is a simple valve lift vs crank angle chart, and it shows two complete cycles. The cam specs are not radical, in fact they are quite close to the x3 cam for our bikes from megacycle.

 

Just in case- Camshaft timing info.

 

Perhaps this picture would help instead. It is from the above article.

I must of missed this, could you link it please.

This one:

 

Now I'm confused again . I thought it was all clear now (not reading too much into that 300 degree wording). Cliff needs to clarify his clarification?

[Cliff]

for me every thing is leading up to the spark. So 0 degrees is TDC just after the spark. The piston starts the inlet stroke at 360 and goes to 180

Thanks Cliff.

 

See guys, I was right

 

In the meantime, I found a very interesting forum at http://www.efi101.com/forum/

 

Searching that forum for, for example, "timing OR phasing OR advance AND injection" yields several very interesting threads with various good information on the subject. And different opinions of course. And also every possible way to express ignition advance, with 0 degrees at any TDC or elsewhere, counting forward or back and sometimes using a negative sign. But most often it's clearly stated which notation is used. And Cliff's notation is not uncommon.

 

Some examples:

http://www.efi101.com/forum/viewtopic.php?t=1074

http://www.efi101.com/forum/viewtopic.php?t=1341

http://www.efi101.com/forum/viewtopic.php?t=2138

http://www.efi101.com/forum/viewtopic.php?t=3954

 

Most people on that forum seem to say we should inject with valve open (when possible) while some expresses benefits of ending it earlier for various reasons. It seems to depend on size of injector and other things. There are more than one mention of 280° [and they use Cliff's notation] as a good starting point but they are not talking Guzzi engines of course.

 

Several posts indicate that ignition injection advance can make a BIG difference in torque but only on low throttles (like 5% duty cycle).

[kadavere]

Belive or not but the Injection Advance have a GREAT meaning on motor control!! If you don't tune this parameters with great care,not less than other map like Injection or Spark Advance,your bike don't have a fast responce to your command.

This is what happens with my motor on Cali EV '97,P8,two inductive pick up's and this is what i understand from a original map i send to the forum.

But I'm not able to translate this on Cliff's map... <_>

The follow is only another map but the best i ever made,surely need more and more work for tuning right.

Why the crank value is to zero? Simply,a barometric corrections is enough to make a right mixture on my bike,yes the crank decay in 20 second but the drowned spark tell me"please MINUS gasoline!!!!!!" I try many and many value but today the best is zero,and true,20 seconds don't have a great effect,best to use the idle lever,like in the OEM ECU use,if this parameter (20 secs) is in future changable from map maybe have more interest to be.

 

HI folk's i have to go at work,20.000 volts wait me today!!

Hello to everybody!!!

 

Do you have a nice Christmas with your bike?Me yes but today snow in Rimini,too rare.....no bike journey.

I ask again your help before say the word end to my personal experience with MyEcu.

The version i have,MyEcuP8,is only a nice selfmade box for run a two cylinder motor,nothing more.....

The OEM ecu an WM441 P8 is unapproachable in performance and electronics compared to MyEcuP8 ( the WMP8 is the same ECU mounted on

Lancia Delta Integrale,Sierra Cossworth ),and with the software for eprom tuning i discover this have 18 parameters/maps to set for best performance!!!

Imagine a little: Injection timing,injection advance,partial spark advance,air temperature injection timing/spark advance correction,oil temperature

Injection timing/spark advance correction,pressure injection/spark advance correction,TPS at idle position spark advance correction,RPM depandant

spark advance correction...and many more parameters to set.

After 4 months of daily test, over 8000Km in mountain,city,highway,sea(100 mt from the water )and many different maps the best i made is the map

i send on the my previous post.

In this vacation days i game with the two ECU's,just to compare it.......but before i put MyEcuP8 to oblivion i'm curious if your MyEcu15 have my same

problem,if for you is not a problem to make my same test:

 

-Bike on the stand,oil temperature 57°,air temperature 32°,RPM 1000/1050,no idle lever pulled.....FAST(a fraction of second) Idle to WOT

movement to throttle lever:

# MyEcuP8:hole and slow RPM answer(if i change the 1st,2nd,3rd column of InjDur to more lean or rich i worsen the things,if i put 600 on the InjAdv

table i have only a hole and no any RPM answer)

# WMP8:fast answer,hi RPM,roar like a lion.....better than carburettor!!!

 

-Bike on the road,3rd gear,speed 40KMh,the last of a colum of car,now i want to cross them........fast throttle (not WOT):

# MyEcuP8:hole and fast RPM answer(the same like before,if i change something i worsen the situation)

# WMP8:immediately answer,fast RPM,the handlebar pull my arms!!

 

-Bike on the road,driver(90 kgs ) and passenger(88 kgs),stopped at the street by traffic lights,1st gear on.......green:

# MyEcuP8:gradually hi RPM,gradually speed increase,change to 2nd gear for take more feeling,nothing of special,like carburettor....

# WMP8:fast hi RPM,90KMh 1st gear,change to 2nd gear,imagine you have a NOX valve to your bike at 2700RPM this open...a tremendous power,

another motor on your hands,the handlebar litterally "torn" my arms,and this only from a "simple" California,i imagine this with V11 !!!!!WoWW!!!

 

-Bike on stand,a night out,-4°all frozen,no optimiser:

# MyEcuP8:impossible to crank,bike does not run......i have everytime the OEM ECU on the lateral suitcase,i don't trust full in MyEcu,open the

saddle,change the ECU.....

# WMP8:turn the key,wait the pump to off,pull the idle lever,push the crank button......4 turns and start!!!

 

All the test with closed loop OFF!!

 

The MyEcuP8 is different in hardware than My15,uses two processor the main and the second,this last for handle the RPM inductive pickup,the

Atiny13 is maybe used to generate an internal aux clock or interrupt for the main CPU.The My15 does not need this,read RPM and crank position

from only one pickup on the phonic wheel.Probably the firmware is not the same and in this is missed the algorithm to handle the fast changing in

throttle and load condition or maybe the ECU have some hardware/firmware problem to synchronize the pickups signal.

If in your MyEcu15 you don't find my same trouble probably is the conjunction of firmware/hardware bug of the MyEcuP8 to create my problem and i

stop to lose time and use this only for safety spare in my journey outside Italy or until an hardware/firmware upgrade is maybe released.

For me the bike first have to be safety and reliable,with MyEcuP8 this is impossible.

I forget this: the bike and WM441 P8 is perfectly tuned and syncrhonized,tested with Axone terminal,tuned for right CO in august 2008,spark new

and/or platinum type,fuel and air filter new,injector and pump cleaned,right fuel pressure circuit,all fuel pipes new,all electrical connection waterproofed

with 3M high voltage electrical grease.

 

Tanks for the help!

The MyEcuP8 is different in hardware than My15,uses two processor the main and the second,this last for handle the RPM inductive pickup,the

throttle and load condition or maybe the ECU have some hardware/firmware problem to synchronize the pickups signal.

Aha... I didn't know the P8 use two different pickups. Maybe there is some borderline timing with the MyP8 that doesn't apply to My15/16M. Or maybe it's a software bug.

 

I'm pretty sure My15M and My16M use the same software (as far as I know they are logically the same except for the built-in pressure sensor on the 15M and different form factors and connectors) but maybe the MyP8 has its own software version, taking care of these separate pickups.

 

I have no idea how many MyP8 Cliff has made, nor if he has his own vehicle for R&D on that one.

 

I know for sure my My16M beats the crap of my WM1.6 in drivability despite the latter also having a custom made map. At first I had a little of the problems you describe but it was cured after I got the map and TPS setting right. Now the WM1.6 is up to par (not better I think) with the MyECU at a 0-200 km/h high-rpm drag-race. At all other situations the MyECU is way better.

[Cliff]

I have a Cali running the myp8.

 

All of the MyECU type are about 90 % common in both software and hardware.

Your map above doesn't show any obvious errors. What are your 4 switch settings?

 

As you made the ECU as a kit you also hare the possibility of a hardware fault.

I'll send your email to a fellow italian in Switzerland. You can send your Ecu for him to check on his bike. That should be a lot cheaper than sending it to me.

Does the WM P8 really have all these features or is it "the software for eprom tuning i discover" that has it?

According to your logs not much numbers/corrections/tuning in most columns.

Or are those parameters avaliable with a gas analyzer and/or your software or what?

 

 

And a Q: Should an egine w less stroke than a V11 & HC pistons have more or less injection advance?

[emry]

Kadavere,

 

I was having similar running problem to yours. The maps I was running were just too lean. So I richened up large portions of my map and the difference was significant. While I have not spent very much time tuning this map it has given me a very startable and rideable map. I am fairly certain that you running issuses are map related and not MyP8 related. Have you measured the stock P8 injector durations with a scope and manually translated them to the MyECU??

 

# TDC is the pulse count for TDC power stroke of cylinder 1 ( i.e. When the spark fires

Please note the following is specific to the Ecu type. This one is for 16m or 15M and will not work in MyP8 . Some minor editing is required.

 

# TDC is the pulse count for TDC power stroke of cylinder 1 ( i.e. When the spark fires

# CylOffs is the number of degrees between success cylinders ( 0-720)

# PulsesPer is the number of pulses for the 720 degree 4 stroke cycle

 

MyECU Cfg TDC=0x1600, CylOffs=270, PulsesPer=48, MissingPulses=3
