Has anyone else seen (or better yet, used) this device?

It requires that you have one of Accuspark's electronic ignitions, which I do, which was very inexpensive and which has been very reliable. The device listed above allows you to use your laptop to program your own advance and dwell curves.

I'm wondering how this gets a signal for what the engine is doing. Most system's that are fitted to carburated engine's use a TPS [throttle position sensor] along with tach signal to determine what your engine is doing. If you go WOT, you want your advance to fall back and at cruise you want max advance.

Hi Kurt,

If you go WOT, you want your advance to fall back and at cruise you want max advance.

That's not what this device does. There's no sensor input to the device and it's not a complete engine control computer. It simply allows you to setup whatever advance and dwell curves you want using a laptop. Once set, the distributor works like a regular distributor. If you don't like the settings, then you can always go back and reprogram new settings.

Yes, Dan, I guess it could overide what the fly weights normally do and give you a dwell curve but you would still need the vacuum advance mechanism. The stock mechanical advance curve is usually all in by around 3K and I always thought the only thing to really be concerned about on dwell was that the coil had ample time to recharge. Guess I don't see a need but am willing to be enlighened.

That looks real interesting. Works on Pertronix too.

For me, I could map it for 10 BTDC for starting and then advance to 30 BTDC at around 2500 RPM.
Simple.

I like the rev limiter feature too.
