In this case for your LTjuan the Opti is considered distributorless and a crank trigger is permitted.

One of the issues with the TorqueHead is the multiple coils. I don't know why you would want them over a single coil, but that is beside the point. Your combo only came with a single coil (it is plenty) and that is all that is permitted.

Not really concerned about the multiple coils.
Do not understand NHRA’s reasoning but that is the rule.

It is a nice bolt on system and ECU easy to tune.
Our B-Body clubs like them.
Especially the Boosted crowd.
Agree single Coil is enough.

Until this weekend was fine using TunerCat for ODB1 PCM.
Been a 15 year labor of love learning most of the Files.
Excellent ECU. Opti is reliable.
Just discovered it’s limits.

Thanks for the help.
