How did you go? Does the idle mixture screw on the rear of the ECU function?


I've had a few thoughts.

"Meantime, with all the really smart people who own, or have owned, D-Jet cars, you'd think someone would have cobbled together a solid state replacement for the MPS."

I thought about replacing the end piece with an encentric piece connected mecanically for the heavy throttle positions & keeping the aneroid part for the rest.

The transformer end is a big piece of the ecu component, impossible to get rid of.

The ipd dial a mixture knob schematics are available, I thought about trying to replace it with a pot & connecting that mechanically.

Ultimately, you can use all the fuel that D-Jet can provide without altering the intake side of the engine. Some exhaust port work, a bigger exhaust lobe & a decent exhaust system will use up all the fuel an altered D-Jet system can provide.

If you want, MegaSquirt is the way to go, it can replace your ECU, TPS, MPS & the trigger points in the distributor, BUT, the intake manifold is still wrong.

ALSO: 36psi? How did you get it? I can't see it doing anything but running super rich at idle UNLESS you used a vacuum referenced regulator.

I noticed that there is such a thing found on Datsun 280Z cars which have Bosch style injection. I would have liked to have tried that back in the day on my 164.

If you can find it, K-Jet from 1974 car works well & will feed a decent engine(BUT the intake manifold is still wrong)

Recently I got a proper length Twin DCOE manifold & thought about combing it with MegaSquirt + the D-Jet parts + a couple of old 45DCOE's functioning as the throttles, but I thought f**k it & bought a pair of new 48DCO clones. Tuning those is a piece of cake. The only reason I would force myself to modern injection is for a blown donkey & I'm not in to boosting things.
