Not the slightest LOL. I just know it's a british word.

Thanks, Dave, I looked it up shortly after my previous reply LOL. My Brit English (Bringlish?) is getting stronger now...

Ok I connected the RPM input to the ground of the coil pack and set the No of cylinders to 6, but my home screen RPM just reads zero with the engine running, I did read about setting the RPM to 0 if the RPM link was not used so I set the lower one to 1000 and the upper to 6000rpm at the moment but still no rpm displayed?


The rpm link being set to 0 is for the nitrous to activate without a minimum rpm reading, but that isn't a concern at this current moment.

Have you tried changing the number of cylinders higher and lower to see if it registers a reading? EX: Cyls= 12 or 3. Sometimes you have to play with it for it to read because ignition systems vary a lot it function. Try that and report back.


Also try probing the wire with the trigger wire on the coil, this may give a reading if the above does not.

Just had an intresting time this afternoon, the ground connection didnt work what ever cyl setting i used, so I traced the coil trigger wire and made a temp connection to it from the maxxy rpm input, set to 6 cyl started the engine and I had a bout 400rpm showing on the max, hmm I thought getting closer, tickover should be around 750 so logical thinking says try it on 12 cyl setting! heres the thing though and it all happened a bit quick cos I started panicking, the revs on the max were showing a really high rpm I think it was around 5000rpm and I heard some buzzing which moments later I learnt was the pulsoid/s as I then started to smell fuel!!! I have not got the pusoid outputs connected yet but there is fuel to one whch was then going into my engine bay. Turned everything off quickly and had a look, not much fuel spilt , i guess the jet kept it small.

LOL quite the day I see.

Once everything settled down I set the rpm in the max right up to 6000 on both settings and then set the cyl to 3 which was a little closer to the tacho reading, long story short set it to 1 cyl and it was spot on....success

Yes, since you're only reading the 1 cylinder, that's what it must be set to.

the 64million dollar question though is why did the pulsoid fire when I have no tps or microswitch fitted yet?

Have you tried setting the Trigger Load to 'ON'? This could be the problem even if the wire is not connected to anything.

Also I tried soldering the RPM input to the coil trigger wire but it wouldnt take the solder, seems like a stainless type of wire, how would you join it.. crimps?
It's more likely to be aluminium wire instead of copper. I would simply crimp a new splice if the solder doesn't take. I prefer splices because they won't break under high vibration.

I must say this is all very challenging!
It always is when it's the first time. All your efforts will reward you with a huge Joker grin for sure!
