Ignition Impulse @ Balancer/Dampner

[A26B]

I found another unusual LT5 goodie in my stash. New balancer/dampner machined for interference fit with the impulse wheel. Once it's properly timed with the crank, would probably be best to drill & tap for small screws to keep it in place.

Anyone care to step forward with some information & suggestions?

I am guessing this was the crank trigger that was to be used when they did the 2 Bentley LT-5 engines...the engine in Michigan that was for sale some time ago had a trigger setup and was a Bentley engine

....you can see the motor in the Thunder at Stillwater video...they actually are talking about it(what the motor is) but the music drounds out the audio

Do you have any of the phase 2 motors? If so what are the s/ns. Geoff gave Britt a document that lists what engine is what car.

24 hole reluctor with the other 8 holes to tell the engine firing order????

We might be able to interface that w LS PCM to run CnP
although still issue of secondaries.

I just love it when you talk like that. WTH does it mean?

I am guessing doug Rippie might know how these work

Yea, it sounds so official! So this would or could be made to work if bolted to the balancer and we use a ECM from an LSx motor to just run the ignition system? We could delete our ignition box and coils and how would we tell our LT5 ECM it's alright nothing is wrong?

Jerry,

I love getting you excited . A 24 tooth reluctor is what is used to trigger the LSx Coil near Plug ignition. A crank sensor on that wheel can feed the signal to an LSx PCM which in turn would send the firing signal to each of the coils. Our Zs have a 9 tooth reluctor so that crank signal is incompatible with the LSx programming unless somehow?? it could be converted. However, once we get passed that hurdle, we still have the issue of 2 sets of VE and SA tables. Some of us have yanked the secondaries, but the calibrations still use both sets of tables since the
Port Closed tables are used when throttle is closed for idle conditions. Probably no way to get injector pulse width small enough with 2 injectors operating. If that wheel was to go into a Bentley or even for marine use, I imagine there was a different ECM for that or at least different programming which would make sense given the different environment the motor would be operating in.

Aside from an alternate ignition system, tell me again what problem you;re trying to solve with the CNP?
