Howell did the chip re-programming, and supplied the wiring harness with the engine spec's that I gave them. I doesn't use electronic spark control, but the pulse taken from the neg coil wire through some sort of filter (anybody know just what that would be?). It does have a heated oxygen sensor for closed loop operation. The initial installation was found to be way, WAY to rich at WOT, and I have leaned it out by adjusting the fuel pressure regulator on the throttle body as much as it will allow. WOT is still just a tad rich (some black smoke, slight loss of power but MUCH better than at first), and I have talked to Howell about reprogramming the chip for WOT. Cruising and idle seem fine. I will supply, after some running tests this weekend, fuel pressure originally, the pressure currently running, TPS voltage, A/F ratio (with an in the tailpipe analyzer) and manifold vacuum at cruise, WOT, and at idle. Is their any other info that I could (or need) to supply so that I can get the chip reprogrammed correctly for my engine/vehicle combo? Also, at cold start, it seams to rev awfully high (2000-2300) for a few seconds, until the IAC brings it down. I would like to avoid this (revving this high cold is not a good thing). Is there something I can do to alleviate this?

They are not inspected. 2) In 2004, 1974 vehicles will become exempt; in 2005, 1975 vehicles will become exempt; at that point, the state will test only (!) the last 30 years worth of vehicles. 3) Engine changes may only be performed if the engine is as new or newer than the vehicle. 4) No (heavy) truck engines into light trucks or cars. 5) All equipment required on the engine in its original vehicle must be present on the vehicle after the swap. 6) You may swap any newer angine into any car, providong you follow those rules, and the car will be smogged as whatever car the engine came out of. If you simply replace an engine with another that was available in that chassis, it supposedly simplifies things a great deal and reduces your likelyhood of a trip to the referee - apparently the smog tech can handle this on his own without the state taking over.

Actually, using the LED bargraph display is great - AND - you can set the "window" of observed values to anywhere, any resolution, by choosing the proper values for REF HI and REF LO on the chip. REF LO does not have to be 0 volts; can be 0.9v, with REF HI being 1.0v if that's the range you want to observe. I just use it for a ballpark indication of what's going on; I prefer real-time recordings from the ALDL for later analysis of exactly what's happening. As others have stated, there's NO close correlation to O2 values and nasty things happening in the engine & you shouldn't rely too heavily on O2 readings.

I am driving an 83 rabbit 1.8L with CIS that has 200,000+ (more like 220,000) miles that still pulls 24+mpg even though I drive it very hard. The system is a breeze to set-up and diagnos since it is mechanical. The largest obstical that I can forsee is mounting the injectors, which you have to deal with using any EFI.

All three were inspected by the state of CA and given a clean bill of health (actually a bill for $30 and a metal plate on the door jam attesting to the configuration) on the first pass. In simplest terms move everything emissions related from the donor car to your ride. Actually you can cheat a bit, use the old gas tank (if not too old) etc. Note that even seemingly un related things like transmissions are emissions related. Once you get your plate on the door jam things can be a little more flexible, the semi anual inspections are not so detailed. Things they don't look at are compression ratios, camshafts, displacement and things they do look for are chrome air cleaners, blocked off hose connections, after-market stuff.
