In the right uppercorner is the sparkduration, it needs to be at 1500 (us). When a spark is build (the power is off the coil) the spark needs time to develop befor a new spark may be build (current on again); this is called the sparkduration. You don't need to change this at all, please leave it at 1500 or if it isn't put it to 1500.. If there isn't enough time for the engine to build a spark, the red eror led will come up....

If you want/feel the need to change the dwellnumbers for a brown coil (I don't think you need to change anything at all)..

First shut down Multispark otherwise your engine will be running on multisparks when bringing down the regular dwell....

Then let the engine iddle; now bring down the dwellnumber in the appropriate cell (the cell which is high-lighted at the time) and bring down the the number (giving the coil less time to charge) When the engine starts to hesitate and skips your dwell is getting to low, now add about 2000 to the number and you should be fine...

Now change all cells according to what you did now (lower rpm cells giving more dwell good for starting the engine , higher rpm cells giving lower dwell good for keeping the coil cold...

Revving the engine from about iddle to 3000 rpm is leading. If your dwell isn't long enough the engine would hasitate skip over first now...

Always feel if your coil isn't getting hot, then you deffinitly giving to much dwell...


Please use the search function at this forum for sparkduration, I have written a lot about it in the past.
Or take a look at the Megasuirt forum, theres also written a lot (maybee to much) about it all

Hope I could help you...

We will see each other in Poland and go over it (I hope)...

Thnx! This is fast service!

4 sure we'll find eachother there! Just look for an knackerd old blue dyane white rear fenders and brown bootlid.

Thnx again!

Well I guess you know my very Patina (read rustbucket) Ami 8 Bouton d'or.....

Geo, Already any experiance to get the 12-spark program running on a windows 10 ?
rgds,

I will try in the weekend, but it shouldn't be a problem...

Hi Geo,

could you please PM me the price for one 1-2-spark unit incl. shipping to Germany?

I tried to email you but did not receive a response.

Thanks a lot in advance,
Thorsten, 1982 2CV Special

PM send..

One more head's up for Geo's ignition!!
It performs very well in the cold. When I got back in Sweden 2 weeks ago, it started at the 2nd attempt after 2 weeks standing at -10 to -16/17, and ever since we have -10 to -17/18 here and it starts well at temperatures <-15°C.

Geo,

Whats the availability 12Spark at the moment?

Could 12Spark be modified to run a GS1220 4 Cylinder????

Cheers
Peter

Pete , it is possible to make a GS run either on distributor or with2 2cv coils... however the 2. set of cilinders can be a little of (about 1 degrees or so when revving fast, but on normal circumstances it wouldn't be a problem... Have you seen the video of my stepson's Peugeot 205 at 1-2-spark???

Aviability at the moment is bad, I can't bring my self to finish the once I have lying around...
I have so much trouble getting my beamer roadworthy (at the moment it looks like I'm only allowed 35kw) by the RDW output from the engine so bugger bugger...

Sorry..
