My car will be carburated. But what a great thread man. Helping to take out some of the voodoo black magic mystery to programming.
Outstanding idea on your part.

People will discount your intelligence Dave,...and not let you play any of their Reindeer games if you show up at the party with a carburetor on your engine. Speaking from experience, the F.I. snobs will look at your car,....look at your engine, see that it has an air cleaner, and a carb on it,...then ......sniff,...pull up their pants a little at the waist, and say/ask:My car will be carburated.

I know, who gives a sh*t? I like it.People will discount your intelligence Dave,...and not let you play any of their Reindeer games if you show up at the party with a carburetor on your engine.

1. Everything was going great till I saw the carb,..then It ruined it for me.
2. Do yourself a favor, and put the F.I. back on.
3. Why did you take off the F.I.?
4. Your car will run alot better if you dump that carb.
5. Any plans to restore the F.I.?
Blahdy, blah, blah...
Hmm your gonna have to use carb method. Let the plugs tell you what's going on.So I bought my MSPNP today, but didn't spring for the Wideband yet as it'll be easy to sneak that into the bank statement in a few weeks... Gonna try to just get it running better without the WB02 for now. I'm sure I'll have questions next week when it hopefully arrives.
Very good question. Is there no instructions that came with the MSPNP? I know there are some similarities between PiMP and MSPNP but not sure if this is one of them. For PiMP i had to cut the wire that the factory 02 sensors used (pin 29) and solder my WB controller wire to it.Ok, so on my MS unit it just plugs right into the stock harness and I'm trying determine where to wire the LC-2 controller into the MS unit. Do I need to cut/solder/splice a wire on the original harness to connect it or use the secondary connector and wire it into that?
The secondary connector is thus far unused and not needed.
Pin 29 is (EDIT) but it's hard to locate because the numbers are nearly impossible to follow on the plug. I had to use Jrichkers EEC pin out diagram to locate it which worked great. Cut (or splice) several inches away from the harness connector.This is what I saw on the DIY site, but not in the instructions that are specific to a foxbody. I have seen where others connected to pin 29... what color is that do you know?
Wideband O2 Sensor and Controller
The MSPNP2 supports many common wideband oxygen sensor systems, including the Innovate Motorsports LC-1 and MTX-L products, the Zietronix ZT-2 and ZT-3 (among others), and most other systems that provide a programmable analog voltage output. You will need to install the controller according to the manufacturer's directions and then connect the MSPNP2 to a programmable analog output from the wideband sensor's controller. You should ground the wideband to the engine block near the factory ECU ground wire to ensure an accurate reading.
There are two ways of connecting the controller to the MSPNP2. You can either connect the analog output to the pin labeled Oxygen Sensor input of the option connector, or you can cut and splice the oxygen sensor signal wire to the analog output. If you use this pin for wideband input, you must disconnect the stock oxygen sensor. Do not ground the oxygen sensor wire if you disconnect it; leave it completely unconnected and taped off if necessary (make sure it can't short to ground or anything else).
After connecting the wideband sensor controller, you will need to change a few settings on the MSPNP2. Section Four has the details of how to change this.
How are they hard to follow? There is 60 pins. 3 rows of 20.Pin 29 is (EDIT) but it's hard to locate because the numbers are nearly impossible to follow on the plug. I had to use Jrichkers EEC pin out diagram to locate it which worked great. Cut (or splice) several inches away from the harness connector.
Edit: Correction, pin 29 color for a 1992 EEC is gray/lt blue
I was trying to say that reading the tiny numbers on the connector and then counting inward to the desired pin is difficult especially if you don't have good lighting. I had to cut back the harness wrap pretty far just to spread the wires out enough to see down in there.How are they hard to follow? There is 60 pins. 3 rows of 20.
