Nanocom analysis - EDC switching this time!

Digging my way through slowly. The link is to a trace of live EDC switching rather than fuelling, using the Nanocom Evolution on a 1995 DT (manual).

Chart below as a picture for those not comfortable with spreadsheets.

Now, if you look at the Alarm chart the alarm is switching randomly and constantly between high and low. Is that normal? Surely once the alarm is off it just stay off and vice-versa, doesn't it?

For what it's worth my 98 DSE does the same thing. Would be interested in what you find out about that.

If it was not normal the Nanocom would tell you. Why are you beating yourself up? I suggest you join the Nanocom forum and ask technical if you have queries.

In the electrical troubleshooting manual, it says the the ECU has a simple on/off input regarding theft. It will kill the engine if activated under 300rpm. Above 300 rpm it has no effect.

This would suggest that the input from the car alarm sensor(s) is always sent, but the ECU ignores it once the engine in up to speed.....wouldn't it?

That would seem to answer that question then.

Well I hope he feels better now

The idea of a diagnosis is not to give you a test result and then say go figure but to give a diagnosis. That isn't diagnostic equipment but testing equipment.

So, presumably every time I shift in my seat I trigger the alarm? Good that it ignores but key part of this part missing from the manual is test at zero mph with no-one in the seat. KISS.

Feel better better? Yes?

Moreover, if every time I shift position in the seat the reading changes then WTF is the point of the reading? I don't need a computer to tell me I changed position. Cannot be that, surely?

Didn't your Mum ever tell you, SIT STILL !!

Well, it seems to work and if Mcapinha's does it as well then that'll do for me.

Mcapinha, let me know if your alarm and BECM suddenly bursts into flames!

It's designed not to work if the engine is running, quite a good feature i would think. Why don't you be a good lad and put the Nanocom away untill you get a problem, and stop trying to create them.
