Along with the Engine Knock Module, I managed to test that this Realtime Clock Module was working as expected, i.e. that I could set the date/time, that it would not forget the date/time when the ECU was turned off and lastly it kept accurate time.
I connected the ECU to my JimStim just to get power, and the USB cable to my computer which was running TunerStudio software;
I then opened the Realtime Clock dialog which can be found under the CAN-Bus/Testmodes button. Make sure that the ‘Enable Real Time Clock drop-down is set to ‘On-board’;
Next press the ‘Set MS3 Time to Now’ button… this will get the current date/time from your PC, so make sure it’s correct!
Now press the ‘Burn’ button, close the dialog and power cycle your ECU.
Reboot ECU and connect TunerStudio;
Open the dialog again, you should have a date/time under the ‘Current MS3 Time’ caption.
Realtime Clock Dialog
Unfortunately I didn’t get a screen dump of the last step, but I did it 24 hours later and noted that the clock had gained around 2 seconds. The RTC dialog allows you to apply a trim to the clock.
That’s about it, I look forward to my logs now to have accurate and real time stamps.
Today I received two add on modules for the MS3X board in my MS3 ECU from diyAutoTune.
MS3 Realtime Clock Module
This module board, adds a real time clock to give my MS3’s SD card logs a time/date stamp.
MS3 Ignition Knock Module
This add on module gives:
two channels of knock input that the MS3 can use to retard spark
a programmable bandpass filter
levels that change with RPM
the ability to assign different cylinders to different sensors, and different gain levels for each cylinder
I understand the Mini A series engine is very noisy, but I hope to be able to differentiate between the engine noise and knock using this module. I have a Bosch knock sensor which I hope to fit to the front of the engine near the alternator mounting bolts near cylinder number two.
I will fit these boards hopefully in the next few days.
