By the question I am assuming you just want to address timing?

I would go with J&S hands down, I have emanage because of the Greddy TT kit but use the J&S for timing. The J&S can retard timing based on boost and RPM's and can also tap into the knock sensor signal to retard if knock is sensed.

Can you really compare them? The J&S is designed to monitor detonation in the cylinders, whilest the E-Manage is a piggyback fuel controller IIRC.

The emanage can control both fuel and timing, but it doesn't sense knock.

Exactly, the emanage does more than the timing and will do the job but you are guessing at the proper timing retard while the J&S is a special purpose unit just for timing and I think much better for the job of timing.

The J&S and the eManage are two different devices, and you cant substitute one of the other.

The eManage is designed to tune and run a car. The J&S addresses timing only.

There were installation issues with the J&S, and I not entirely sure if those were sorted out. In theory, the J&S is a good addition to an eManage. You can tune timing and fuel with eManage, and then allow the J&S to act as a safeguard against detonation.

If someone has had experience with the J&S when used in conjunction with the eManage, please contact me or post up here. Have the blown coils and installation issues been resolved?
