Mefi 4A ECM and harness. It was used on a Whipple motor that I sold.

Ended up selling long block separate, buyer had no need for ECU. Engine was tuned on dyno with it.

$900 or best offer. You pay the ride.

Bump! This will replace a mefi 3 ecu, I know they’re pretty hard to come by. Make me an offer.

This harness has been reterminated to fit a whipple top mount , may save someone alot of work!

Where's the whipple? That's what I want.

is the harness and computer still available?

Yes it is still available

What changed on the harness to make it fit for a whippled motor?

Everything that now plugs into rear of the whipple was re terminated and cleaned up vs having wires rolled up and wadded everywhere
