Change log:
Is this software locked to a single pc? I have my smaller laptop which has 1 screen I use for mapping, however I currently use a shared drive and my home twin screen setup for in depth editing.
Yes the key is just for the particular computer.
If you want to use it on another one, please send an email witch machineInfo.dat from the other PC.
Thanks, so I can run this on each PC with the info information sent?
Excellent. Many thanks.
hi,
is there any know bug that can give engine stall ?
i have DSG with saab DI cassette in a saab, and going past 1bar boost i stalls randomly i need to turn off ignition and restart the engine, then it drives again.
DI cassette is DIRECT ignition, NO DWELL so i have spark angle difference yes i know all works fine. until switching to V3 gave me the tall problem.
gone switch back to v2 and check to be sure. but only change whas software.

What I can see on the log is that once the ECU resets, the cause is power reset.
So for 99% there was power drop on ecu. If the ECU resets by watchdog (eg. software loop, program hangs) there will be different reset reason on the log.
Or maybe you just turn off / on the key if you saw the RPM drop.
What I would suggest try to set dwell time to at least 1ms or even better 2ms.
I think it doesn’t matter for that coil but maybe help.
I cant see any suspicious thing on the log
Hi, thanks, but thats probably when i turn ignition on and off. 2 times.
Need to re-check but changing dwell time changes ignition Angle. Been driving these di cassette like this couple years now on v2. Dont know for sure anymore.
EDIT so yes longer dwell adjust ignition angle.
Di cassette fires low edge trigger. So i Should need dwell 0 .
EDIT: just tested on v2 no problems.car stays driving.
So it has to do something with the dwell time being so low. On v2 its not a problem. I am driving 0,2 dwell time.
Edit 3 
So i uploaded v3 again with different lapot.
Changed dwell to 0.25 and adjusted ignition angle
To compensate. Can not replicate the problem at this moment. So will get back here when it does.
Otherwise i think it solved.
If your dwell changes the ignition angle then it is not correct as youbhave spark on the wrong edge.
It looks like you output signal edges are inverted.
Later i will try to find any documentation for DI cassete to advice you how to control it correctly.
this is how you set it up 7 years on teamvieuwer and calibrated first dbw from saab.
there is no option in ecumaster to invert the signal right ?

What I understand from the documentation the capacitors charging should be at least 2.5ms, and charging starts on the rising edge of the coil output and spark is executed on the falling edge.
So I would set a 3 ms dwell time and change the coils type from Coils without amplifier to Coils with built in amplifier.
Please try this setting and check if the ign angle depends on the dwell.
After this change the timing can change so please check it with the lamp.
Hi,
It doesnt fire when i select coils with amplifiers.
At least thats what we found out 7years ago.
The capacitor is charged ready. And the trigger needs to be active as long as the capacitor decharges
Is what i understand.
I could make a dwell time correction table .
That would compensate ignition angle.
Simple math calculation.
Wil test some stuff when i am back. Dont have possibilities at the moment to check until 22mei.
“. The voltage on the trigger
pins is 12V and it triggers on the falling flank when grounded (500mA peak). The trigger must at least
be held low for the discharge time of the coil which is about 500µs. There must be a 2.5ms charge
time between triggers to avoid damage to the cassette. The recharge of the capacitor starts directly
when the trigger goes high again and the charge time is 2.5ms at 12V battery voltage. It is important
to minimize voltage drop in the harness as the charge time will rapidly increase with lower voltage
(3ms at 9V). Charge voltage can be monitored the on pin 1.”

It says wastespark gives each cilinder half the capacitor energy…lol… Guess why aftermarket doesnt get as far up the hp ladder with di cassette… Wastespark.
The problem could be that when the active coils are selected there is not enough current to ground the coil.
So with passive coils the spark appears as soon as the dwell starts (output is grounded).
The dwell isn’t calculated precisely as the spark (spark precision is in us).
So it can’t be like that.
I think there should be a different ignition output mode for DI cassete.
It cannot be properly driven with existing options.
