We put a MegaSquirt on Tim Schuh's 1984 RX-7 GSL-SE. It's already fuel injected, but it used a restrictive flapper-type air flow meter. The MS allowed us to ditch the AFM, and of course tune for performance and allow for future mods and improvements.

(46K) 640 x 480	This is the factory mess - er, harness. The silver box is the factory ECU. The two white plugs at the bottom are a pair of Molex plugs that we added. The harness for the MegaSquirt plugs into those Molexes.	(35K) 640 x 480	This is the MegaSquirt hearness, without the hood on the DB-37 connector. That's the end that plugs into the MS.
(18K) 640 x 480	We fitted it into the glovebox. Lacking mounting flanges, we just zip-tied it in.	(20K) 640 x 480	It just fits...
(19K) 640 x 480	...if you make a hole for the plugs to hang out the back.	(31K) 640 x 480	The factory TPS was a plunger-type setup, and didn't read the whole range, so we had to add a rotary TPS.
(34K) 640 x 480	The fact that tim was removing most of the crap on the throttle body (like cruise control and the secondary throttle close-off) helped make room for the TPS and a bracket.	(35K) 640 x 480	works like a charm!
