wasted spark

you're clearly no engineer and no genius as with a wasted spark system on a 4 cylinder engine you only have pairs of cylinders sparking - not all 4 
1 useful spark and one wasted.
and it's been commonplace on engines for at least10 years now, so is obviously a flawed concept
what a prat

I'll say it again: I had a 'base chip' from Jano and it would not run the engine all. I then had the car taken to Field Motorsport who gave it a full live map and it has run like a champ ever since.
So if you have a 'base chip' or an unknown chip in there it almost certainly will be for a different spec engine. Where was the chip bought from?

Yeah I have seen some oe amps not work on WS, only very few though which is bit odd as you would think they are all the same, I run 2 oe Amps on mine with no issues, go figure lol.
You must have used a diode mod for the tacho then, we can make them on request. You will need to remove the rev counter wire if your using the diode pack mate as the voltage to the clock will be too high if the resistor is bypassed

I have the diode mod on my car and Tacho worked fine. Now I've changed the Tacho for another one and the rev counter is dropping over 4k. Apparently the voltage for the complete dash is dropping over 4k.
What do you mean exactly with removing the rev counter wire? do I Need to remove it from the ECU plug? Or do I Need to do another mod to the Tachometer?

The solder mod to the Tacho is not in place. Only thing I have changed is the Tacho itself as the only one that worked belongs to a mate. So I sourced another 4WD Tacho unit and strangely now the rev counter is cutting out above 4k. I will swap back to my mates Tacho and see if the problem is still there or not. Thanks for the quick reply!
