The first step will be to check for 5 volts at terminal "C". I didn't think about that since I was closing up shop. Once that's established the remaining two terminals will more than likely be in the correct location and the MAP signal is just steady at max Kpa waiting for crank mode. That makes sense to me considering if there were no MAP sensor plugged up at power on it shouldn't show a WOT reading but instead 0 I would think. When I checked for diagnostic codes there were none and if the MAP sensor was disconnected I believe it would set a code before the engine was started.
I didn't attempt to start it today due to a late start and focus on putting it back together. I addressed the coolant temp sensor, I didn't feel modifying the $13 3-wire sensor was the best approach and since the coolant passages for the 3900 are not the same at both ends of the cylinder head gasket area I decided not to try to tap and dye or enlarge the current passage to fit the 3-wire sensor. What I settled for was a second stock sensor located in the coolant crossover. It will not supply input to the overheat light but at least the gauge will work. I can always tap it up to the Fiero sensor which is the same size as the 3 wire sensor.
Hahha. Cool. No power steering pump to worry about there either with your car.

1994 3100 BERETTA. 200,000+ miles
16.0 1/4 mile when stock. Now ???
Original L82 Longblock with LA1, LX9, LX5 parts
Manifold-back 2.5" SS Mandrel Exhaust. Hardware is SS too.
Finally broke down and purchased a CPS after getting tired of the two older ones teasing me.
It's running very rich and doesn't have the mufflers/glasspacks on yet and sounds pretty mean. The sound was taken from video on a digital camera and isn't all that great since the microphone can't handle the rasp from the exhaust note, but it'll at least give you an idea. The turbos can be heard spooling up just before the rich condition chokes the engine out.
Now I need someone to send me a known TGP 8F code XDF file, bin file and ADS file for datalogging in Tunerpro because the one I have does not work, I am not able to verify the bin file after loading it into the Moates APU1 emulator, the A1 code however works fine and allows datalogging and emulation at the same time. Since it's turbocharged I need the 8F code to work.
Glad to hear it running. Sounds like you have it cam'd too?
It sounds like it but I believe that might have more to do with the rich tune because when I switched from the A1 (Beretta) code to the TGP code it started running a lot smoother. The cam was reground so there is a bit more duration.
Right now I'm accepting the disappointing performance of the Moates APU-1 emulator I spent $325 for that will not do what it's supposed to do, so now I'll have to hook up the Zeitronix WBO2 unit that I purchased which will take a lot more work but hopefully will get the tuning job done.
Joseph.... I don't know if this is possible with your ECM and BIN but I was able to pass the WB output through the 16149396 ECM with DF code using the AC pressure input and monitoring it with Tunerpro after I changed the .ADS file. I had to create a table in the .ADS file to convert the WB voltage. Not very hard to do. It's nice to have the WB info listed with the other data. I have an Ostrich and it acts flakey sometimes.

Thanks, I have the Zeitronix wideband O2 6 channel datalogger that I plan to wire up tomorrow for backup since it works independent of the ecm. I went out and tried the APU unit again and surprisingly it behaved a lot better. I was able to verify the uploaded bin with the Beretta files but it's the TGP code I need to work right. So far it appears it will emulate using the TGP code once again but I'll have to try some fiddling with the datalogging to try and get it to work.
The instructions are a bit confusing at times so there is a lot that can go wrong to cause a problem. I'm going to email Mark in hopes that he has a known working bin and ADS file for the TGP code because mine isn't working.
On the up side the exhaust is pretty much complete except for the support hangers for the mufflers. I still need to add the tranny fluid and make an adjustment to one of the axles after which I should be ready to start test driving.
