Alright guys was hoping I could get a little help with this 99 prosport. So we were having problems with cam sensor going out and got tired of replacing but would run fine for awhile until it went out again. So he bought a cam sensor that is an ignition unit built into one. It has some switches on it for tuning on the fly etc. My question would be how would I wire this in when the old thunder heart ignition module is in? I know I'd be disconnecting some if not all of it but I usually work on sport bikes so was hoping one of you guys could spread some wisdom onto me. Thanks for reading

Please post a picture of what you are planning on installing.
Do plan on cleaning it out guy says he bought and installed this far and let it sit for a while after not knowing how to wire it

That's what I was thinking just didn't know if disabling it would cut the gauges and such out
VOES????
Say you have 3 ignition curves: 10° - 40° - 55°. VOES fails in either vacuum or electrical, you lose the 40° curve. Thus this abrupt 10 to 55° range.
Instead of vacuum you now change degrees with rpm. No change in carburation if not FI. Still safe to ride.
For a back history, guys would disable the VOES for this snappy ign curve. They'd think they'd get more HP but the abrupt change says otherwise.

So if I'm not mistaken on this particular ignition leaving switch one down would be deactivating voes?
I agree.

I remember back in Texas my mechanic, Ron Kujat, in Kerrville said the ignition module,in my Thunderheart was going bad and he bypassed it and installed a traditional cam sensor ignition in the cone. It worked great until I got to AZ and fried my whole electrical system with a bad voltage regulator putting out 18 volts. I old school wired the bike at that point. I don't know how he bypassed the Thunderheart and he passed away a few years back so I can't ask him. was a gem.
I'm sorry for your loss. Ive been pretty busy with some other projects and life in general but I plan on diving into this real soon and will report on how easy/pain it was! Thanks for the reply guys !!
