96 Rav4 with Toyota 3sfe

Postby Jamesl » Thu May 06, 2010 6:25 am

I have successfully 'squirted a 1996 Toyota Rav4 using the completely stock ignition system and a DIYPNP kit from DIYAutotune. I didn't have to change any of the stock wiring, the MS unit plugs into the existing harness and the only change under the hood was to disconnect the vacuum hose running to the stock MAP sensor and run a hose to the MAP sensor built into the MegaSquirt unit.

The key to making MS work on the RAV4 was figuring out the ignition system and idle control. My '96 model has a distributor with a cam angle sensor built in and a crank angle VR sensor that monitors a 36-2 trigger wheel mounted on the crankshaft. In the end, I ignored the cam sensor and just used the signal from the crank sensor. Once I figured out the right settings, the car fired on the first try.

To make the idle work, I had to build an add-on splitter circuit and set up the software for PWM Closed Loop operation. It idles fine throughout warmup and in stop-n-go traffic.

You can read a "how to" article on the project, including some screenshots, here: "How To" article
