This is a short description of how I converted my Volvo 240 GLT -82 (B23E engine) with Bosch CI to electronic fuel injection, controlled by MegaSquirt Do-It-Yourself fuel injection controller!
The MS controller in the box, lying on the floor in the car.
The homemade doublesided circuit board, with almost all components mounted.
The PCB is modified, with larger lines and holes to make it easier to make
the board at home. It takes some time to solder all components on both sides!
Doesn't look too nice, but it works. Intake manifold, injectors, fuel
rail and pressure regulator from a newer Volvo 740. TPS from some Opel,
many Saab's uses the same TPS too. Bosch number: 0 280 122 001. Here are two
pictures of the TPS: front, back.
The new TPS doesn't fit directly, you have to cut of about 8mm of the axle,
and make some new holes in the fastening plate to make it possible to fit
the TPS correctly.
The old injectors were mounted in the header, and the new ones are mounted in
the intake manifold. So I have to leave the old injectors in their place, to
avoid four large holes into the intake.
I used the original temperature sensor, and replaced the strange vacuum
thermostat (used for the vacuum lines to the EGR valve) with one more
temperature sensor of the same type. (The first originaly mounted on is used
for the teperature meter on the dashboard.) Here
are the thermfactor.inc file, if anyone are interested.
I have a friend who used to work in a car manifold factory, so he got
me one round nut with the right thread that fits my O2 sensor perfectly. I
soldered it into my exhaust pipe with silver solder. And the O2 sensor is
also from 740.
Me, soldering the aluminium box.
