deadtime

[NiceMan]

Project has deka 2300cc injectors, manual say opentime 1,6ms and clocetime 1,4ms so if i understand them dead-time is 0,2ms ? Correct ?

Open - Close = Deadtime

[Quagmire]

I am not sure you can make that assumption, I imagine that just means that they close quicker than they open.

Only real way to know is to flow test them, or find the data from somebody that has.

If unsure then physically flow them and confirm.

Data-card say:

mg/pulse --- P.W ms/pulse

2 50
4 100
6 150
8 200

Now not has possible make any flow test so can use factory list

And if dead-time cannot calculate them why ms3pro manual write this ?

Sorry guys... this is this, just try figure why ms3pro works so nice in idle 1,5 week, 10 race and its lost good idle like snap fingers... other way works.

I'm not understanding that. What is the "this"?

Unless the manufacturer's data is taken with your injector-drivers and your fuel-pressure regulating system and your fuel type, the data is going to be only approximate.

Ok, i not ask anymore =) I work my way... Possible need sell mega3pro and find better... if not find what its go wrong after one week drive, someone say at 3% ms3pro has problems in box...

And sorry my english... finnish is better but finnish forum is small hire... And only some unit ms3pro ultimate in Finland..

You need the Calibration Curves from Siemens-Deka or the equivalent Ford ones.

This might be what you are referring to:

Any ECUs made before that date should be returned for a warranty update.

Thanks so this is possible problem in box, next race come next week and 2 week later has another so no much time wait =)

But sorry, i use many night to solve problem and i try one time more and them need start think at problem is not program, setup, its hardware, so sorry my write, newer need make anything when tired...

Anyone cannot tell at this extra open time not see in tunerstudio, meen at ms3 calculate open time 1ms and this show in tunerstudio but real open time is like 2ms... this tell wait idle come so hard get work anymore, i am back to this when check box date.

But one good at this car win Sweden gasoline street, no matter at not get full power out yet and another problems too =)

No calibration data for FI114212 212 lb/hr
Only can find specification sheet.
All with suffix -cs are Calibration Summaries.

[NiceMan]

Need look if has time make calibration test but thanks to everybody, need look if can get oscilloscope so can look what ms3 give out...

This is only data what find.

I too think the Siemens Deka injector dead time is a bit unclear. I'm using the Siemens Deka FI114992 875cc injectors. My dead time is programmed as 0.9ms @ 13 Volts (100%) in the MS3X table, and the engine works well.
Looking at the voltage offset curve for your 2300 cc injectors, the curve looks very similar to my 875 cc injectors.
If you have no better data, try the 0.9ms @ 13 volts.
Hakkaa päälle!

We run 1ms and looks work ok but think at come hardware problem now, more information later.

Juu hakkaa päälle Suomi poika =)
