Pulled from my buddies M50 swapped E30. This is what Turner said when he asked them what it was
"That chip is a for the silver 413 DME but to deactivate the EWS system in it.
It's a performance chip but isn't tuned for any specific modification
(cams, exhaust, flywheel, etc). And it is not tuned to forget the speed sensor signal. That chip is the basic performance chip plus EWS delete."
Looking for $75
