Alot of LS1s were starting to miss and showing random miss fire codes... after searching every mechanical issue you would think would cause the problem..
Guess what it was, bad after market balancers throwing off crank sensor..... don't ask me how, but it did. When we finally traced the problem, we called ASM and they said "if you had called us first we would have told you that was it"Grrrrrr
Who would ever think your balancer would cause that, Especially not imediate after install. weird.

I have an idea that might allow a 730 to work on an ls1. Need to test out my DIS idea first. If it works, the it can be applied to any engine..

The crankshaft sensor on ls1's can sense crakshaft deflection (to detect misfires). The bad balancer caused deflection. Sensor is too "dumb" to sense the difference..

It can detect very small differences in DRPs, and thus detect an out of balance state/ misfire, from what I've been lead to believe.

I love this book!!

Are you sure of that claim?. ie measuring deflection.
