Ok, in my most recent thread, I stated that the walkthroughs for the DPFI-MPFI swap were wrong in their pinout statings, which, according to Honda service manuals, is true, however, Some electrical engine diagrams show that the pinouts described are correct, such as (I believe) the Helms manual. I was using a Chilton Manual, for 84-95 Civic, CRX, DelSol (Which is spanish for "The Sun" by the way, lol) All Models, which follows the Honda service manual for most procedures done on the car.
I apologize for not explaining this earlier, however, the car runs great now, and is insanely torque-y (torky lol), it spins first, and on quick shifts, even at low RPM, it will still break loose in second, plus, at mid range in first, it will spin the tyres while you're moving.
And on a side note, the MPFI swap can be done with ANY MPFI dizzy, including the HF, and if you don't believe me, go to this site:

and look up EVERY PART NUMBER they have available for both the HF and the SI dizzys, also, ANY MPFI ECU can work. The Si (PM6) just has better fuel and ignition curves. (As long as the OBD is correct.. or you're chipped.)

>>There is one BIG difference between the HF and SI dizzys, and that is the wire clip on them. If you have, for instance, a HASport DX-Si conversion harness, you will either need to depin the harness, and match up the wire colors, or depin the dizzy, and do the same, either way, it will work for you. (Depin them ONE WIRE AT A TIME, b/c there are two white wires on the OBD-0 (Non-OBD) Dizzys, and if you mix them up, it may cause alot of heartache. Contrary to popular belief, the two whites are NOT always different gauges.)
My boy and I can say for sure that we are VERY HAPPY with this swap (D15B2 Block/D16A6 Head, 9.2??? compression) Even after all the work involved and many cigarettes smoked trying to work out the bugs we had.

meh.. you don't even know the heartburn that arguement has been causing... it got my boy and his dad in a fight, got me in a fight with the ENTIRE tuning shop up the road.. except one guy, who actually gave me a hand, when I drove the car down there on two cylinders (still did 70 lol the reason I like hondas) and he tested the plugs, wires, injectors, etc... found out that the ECU was hanging one injector open, and four injector was powered on both sides... end result was a crossed wire INSIDE the harness.. had to tear the whole thing apart and find it with a continuity tester... but it's all good now, and we love it
