Tindie Weblog | Miata/MX5 1.6 to 1.8 Engine Sign Converter

The Mazda Miata, or the MX-5 because it’s known as over right here within the UK, has been a vastly widespread mannequin. As a small sporty little on a regular basis driver by to tremendous modified observe automotive tasks it’s broadly thought to be an ideal automotive. The sooner variations of the Miata/MX5 had been equipped with both a 1.6-litre or a 1.8-litre engine. This Engine Sign Converter is designed to simplify an engine swap from a 1.6 to a 1.8 litre.

I’m no Miata/MX5 professional however there are conflicts between the 1.6L and 1.8L variants throttle place sensor (TPS) and the 1.8L idle air management valve runs at a special frequency than the 1.6. This implies folks trying to place a 1.8-litre in as a substitute for the 1.6 needed to both drill holes into the consumption manifold and add an adaptor plate to suit the 1.6-litre throttle to the 1.8-litre, or swap the whole ECU and cabling. Each these choices sound complicated with the ECU swap being the least invasive but additionally extremely complicated versus the everlasting and “one likelihood to get it proper” manifold drilling strategy.

This Engine Sign Converter permits your 1.6-litre engine ECU to speak on to the 1.8-litre throttle by merely splicing it in with a number of wires. It appears to my untrained eye that this protects lots of rewiring work and means you don’t must fiddle with getting key transponders to speak to new ECU immobilisers and the like. After all, utilizing this equipment and this strategy signifies that it’s additionally totally reversible.

Equipped totally assembled this board has a conformal coating so it must be long-lasting and fewer vulnerable to corrosion. There are onboard potentiometers with which you’ll be able to alter your engine idle and large open throttle (WOT) positions and it’s even equipped with a small screwdriver to make these changes!
