Supermid M1 install in 88-91 crx

[Bunger]

From what I have read, the M1 isn't setup to work with a 2 injector TBI system (which is what the DPFI pretty much is). So you would need to convert to MPFI, which can be done by swapping distributor, ECU, and intake manifold + tb, and some wiring. I've done a number of these conversions myself, but if you don't at least feel comfortable doing things like changing your oil or installing a car radio, I wouldn't suggest you attempt this conversion.

The write up above is good, but I should add that all the connections you needed were right at the ECU: constant power, ground, VSS and an injector.

hey Daniel,

So it looks like installing a Super MID should be fairly straightforward on a 1991 CRX HF then as well? I don't know much about electronics at all, so I would pretty much just be following your DIY.

Also, do you feel being able to watch your FE all the time improves your FE?
