Do you mean were the three different coils showing significantly different charge times ? Or do you mean were the individual charge times fluctuating a lot from moment to moment ?
If the former, a couple of pages back in the thread I posted the ignition coil charge times at idle for the new now removed coil pack:
http://www.frenchcarforum.co.uk/forum/v ... &start=930" onclick="window.open(this.href);return false;
Charge time 4.09ms
Coil 1/5 +0.11ms
Coil 2/6 +0.06ms
Coil 3/4 +0.19ms
If you mean are they fluctuating a lot, its hard to tell when I can't graph the figures but I recall that the individual coil figures did seem to be fluctuating significantly although I don't recall which ones and by how much.
I'm still not sure that I understand what the figures are showing. Charge time I understand - its how long it takes the current ramp to reach the peak current each time the coil is charged, in this case 4.09ms. Fair enough.
But I don't understand what the individual coil readings represent. The heading in the Lexia is "Charge time reg. :" whatever that means ? No documentation of course... does that mean that you add the base charge time (4.09ms) to the individual figures, say 0.11ms of the first coil to get the actual charge time of that coil ? So the charge time of coil 1/5 is actually 4.20ms then ? Therefore the individual figures are just showing you the relative difference in charge time of each coil...
My engine problems were in two batches. One batch came with the blocked exhaust, the other with a faulty positive terminal.
The faulty terminal was pre-Lexia; I swapped countless items at great cost with name brand new ones. Ultimately it was fixed for about $60 with new starter cable (heavy gauge and slightly longer) and a new brass battery clamp pair at the same time.
What symptoms were you getting from a faulty battery terminal ?
I've got a new negative terminal but haven't fitted it yet. These halfords clamps aren't that great really. I originally went and got this one:
http://www.halfords.com/webapp/wcs/stor ... yId_255205" onclick="window.open(this.href);return false;
Which they say is a "four way" terminal, whatever they mean by that. Turns out that the hole for the cables which you can't see in the picture is far too big for the two cables I need to insert, even if I fold them back double.
So I took it back to get this one which they claim is a "two way" terminal, thinking that the hole must be smaller in diameter to suit inserting two cables:
http://www.halfords.com/webapp/wcs/stor ... yId_255205" onclick="window.open(this.href);return false;
Well it turns out that the hole in the main clamp section is slightly smaller but only just, and its still going to require folding the two cables back at least double maybe even triple to clamp properly, which is why I haven't done it yet while I explore other options.
Even the guy in halfords couldn't tell me what 2 way and 4 way meant....it didn't seem to have any correlation with anything on the clamp - both require at least 4 thick cables to get a decent bite on the clamp, and while my positive terminal has 4 cables the negative only has two, and not very large at that.
Still trying to decide how best to fix the battery clamp.
I guess the moral of the story is NEVER assume that because you have replaced something a few months earlier with a brand new part, that it can't possibly be the cause of the problem you're seeing... if you think that way there are some problems that you will never find. Every symptom needs to be treated on its merits without assuming replaced parts are working 100%, certainly for parts like coils which can often become "iffy" rather than completely fail... 
It's never used.
My driving is really quite moderate and smooth most of the time but I like to open it up sometimes, where its safe of course. I like to have the power on tap and have the responsive throttle even if I'm not using it all the time.
whats going on ?
