If anyone doubts swapping to COPs will be an advantage:

Those are the Corolla COPs that work on the bench but won't spark in my car when both coils in a trigger series are plugged in. I suspect the ignitors in them have been damaged or something so I've got another set of different coils on the way. Got some from an RX300 for 30$ shipped.

How the hell did you get your camera to catch that? The discharge must barely last a couple ms. Cool pictures.

so why would you bother NOT running them sequential ?

Lazyness? Its the only reason I can think of if your ECU is up to the job.

Or lack of knowledge like in my case. I'm running an AEM that supports sequential but I don't know how to do it :bang: I've read about it in the manual but I'm definitely "mechanically challenged" and in terms of electronics I feel like a Neanderthal :mad:

Got my COP's on the way, registered on an MR2 engine swap forum where they all put Camry V6's or MR2 Turbo engines into the MR-S, posted in the wanted section and got an offer straight away set of 4, £35 ~ $57 :D
