Southern Mini days last year was the first (only a week or so after the engine was finished) - but there was no Megajolt at that point. I've been on several local mini runs around Kent, went to Brooklands Mini day... and there's this year's Southern Mini Days coming up next weekend, when she'll be o...

Hmm... totally forgot to update this! More about the general car work can be seen here . http://www.spetom.com/storage/dompics/13.jpg The SC trigger wheel was eventually replaced with a MED machined pulley, solving the clearance problems and I've been running the MJ with a basic map for several mont...

Yes, it's the same cluster again. I'll look into picking up one of those regulators and post again when I've run a few tests.
Thanks

Tom

Hmmm... it's happened again, which seems a bit of coincidence.
Any ideas how I can test what's going wrong here?

Hmm... good point.

Well, it was a nice dream while it lasted

Theoretically, could the MegaJolt calculate the speed of the car? Using data from the sensor, and a user-defined value for the size of the wheel, could a fairly accurate speedometer be created? (Of course, I'm ignoring the fact that there isn't really a way to output this, but a speed would be inter...

I may be wrong, but I think the standard voltage stabiliser is supposed to put out 10V, not 12.

You can get fairly cheap semiconductor-based replacements for classic stabilisers that output a constant 10 rather than the on-off of the bi-metallic type. I'll look into getting one and switching them.

Sorry - all I seem to do nowadays is butt into your threads, Ryan. As I have a similar engine / MJ setup, I thought you might like to know the results of my experiment with an A-Series single terminal temperature sender (exact model unknown) and the Aux Input of the MJ. Although 'experiment' isn't r...

Thanks for the help everyone. It was indeed a problem simply solved by reversing the direction of the clip!
Who knows what else I'd have pulled apart before I was aware of this!
Thanks again.

I should have known you'd have an account on here David! Sorry for referring to you as 'the guy'

I'll try reversing the clip on plugs 3 and 4 when I get back home. Re-reading Alexander's post, this is also what he suggested - I'm kicking myself for not testing it out this morning!

Thanks Alexander, I'm fairly sure I've got the clip on the right way - on the model I have, it's got a little arrow indicating the direction. I've emailed the guy who made that comment in the hope that he can explain it further. Maybe it's just a quirk of certain models of timing light. As far as I ...

So maybe it's nothing at all. Browsing other MegaJolt forums, I find this: http://www.locostbuilders.co.uk/viewthread.php?tid=95782&page=&contribmessage=none Two things to check: Are you checking it with a clip-on timing light? If so, 1 lead from each pair (1-4, 2-3) will trigger a good flas...

Further tests: swapping the wires around had no effect, so it isn't the connection. Swapped around the coilpack connections and the plugs, so what was going to plug 1 was going to 3 (and vice-versa), and 2 was going to 4: instead of 3 and 4 having problems, 1 and 2 now did, with 3 and 4 being fine. ...

This is a continuation of the problems mentioned in Nitropixie's thread: http://www.autosportlabs.org/viewtopic.php?t=1970 . Briefly, using a timing light to check the advance, I noticed that while plugs 1 and 2 produced gave good, regular pulses, 3 and 4 were irregular, frequently missing beats. I ...

I only put a blue LED I had lying around into the 'two holes' to test it: currently having a bit of trouble finding 2000mcd clear green - everything seems to be 'ultra bright' - around 6000mcd!
