You will need to wire a higher gauge power wire, fuse, and relay in. Also the ground will need to be beefed up.

This is an interesting thread.

It appears as though the 90 ignitor didn't have a current limit? Did you test the 91+ the same way. Years ago, I did, and the 6-7A current limit did seem to exist in the newer ignitor. What happens is that the transistor comes out of saturation, causing the voltage to climb inside the ignitor. This would get the ignitor hot and
kill it quickly if it were run like this for too long.


Are you adjusting dwell to match these other coils? I noticed that the 2G DSM ECU I was testing seemed to drop dwell off pretty quickly as RPM climbed, so you'd never really hit that 6A limit. With a quicker charging coil, you'd be most likely to hit it at idle.

FWIW, also the ignitor plugs are readily available now, new. Either the 90 or 91+ style.

I was going to send you a link to this thread, seeing how this is right up your alley. As far as I know, no one has mentioned a current limit or anything you mentioned. I did get one set of twin ignitiors set up and it ran good. Never had an issue, nor did I really run it much.

Based on my bench measurements of the 2G ignitor, I wouldn't expect it to help a lot.

My concern, and I saw someone else post this early in the thread, is that it would be hard to get the ignitors matched so perfectly that one wouldn't release slightly before the other, and possibly lose a little bit of energy on firing.
