It's been a while folks.
I need your help!
I have a 4G32 and the dizzy has Sigma electronic guts with a Sigma module.
My issue is that when I am accelerating, when I reach 4000rpm the tacho launches to 8000 rpm for a second and the engine jumps a little.
The hotter the day the worse it is and doesn't really do it in the morning
I have a resistor type GT40 coil and I'm also running a condenser on the coil for radio interference.
Any ideas or help would be great!
Alternatively, what msd units at people using that I could fit?

Re: help. ignition problem
Hmmm, strange... do the revs actually jump, or is it the tacho that's jumping? How long does the burst last? Could be a bit of faulty wiring going to the tacho...
Re: help. ignition problem
the engine stutters and the tacho jumps. probably half a second.
it only happens when the electrical system has warmed up. Im going to try disconnecting the tacho tonight, then i will swwap the ignition box, then i will try a non resistor type coil.

Re: help. ignition problem
I have the exact same problem at the moment. Mine is intermittent and generally under light load. Going to be a process of elimination. I am going to start with the ignition module and work back from there.
