however the keys have "W" stamped on them so I'm guessing they don't have the chip necessary to activate the immo.

My AHA ecu is already socketed, would a custom chip be able to disable sec air and sec O2s? or is this a function of the ecu outside the chip? I was under the impression that the chip held not much beyond fuel and timing maps and same basic settings.

Or if I chipped the ACK ecu, would a chip be able to override the build-in immo?

Thanks for your help Andy.
