Timing and AEM/VEC

[Jack B]

When the timing is set with the AEM, is there any cross check that verifies what the timing is. In other words, if you could use a timing light, would it match the aem setting?

The reason I am asking is that it has always bothered me on the VEC that we are sort of blindly adding timing and don't know what actually is happening. This is not taking away from Sean, he has done as much or more than anyone to support the viper community. To go one step further some minor issues still remain with timing and high speed misses.

With all that said, about one year ago a friend and I started trying to log true timing. It turned into the search for the holy grail, we are finally at a point where we can accumulate some data. It seems to be working and just needs a bit of fine tuning. We are using an optical sensor on the damper and comparing it to cylinder #1 coil pack, therefore, it is exact. We just did my Gen 2 and are going to do a Gen 1 next.

I would be willing to bet that some of the high speed misses can be linked to a timing anomaly and the logging will be able to catch it.
