94 olds vert Posted July 9, 2011 Report Share Posted July 9, 2011 The 94 CS analog was mine. Floor shift. The 1994 guages are different from the 92 and 93s. On the oil gauge they had the pressure. The later ones only got dashes with no markings with numbers. Then 95 has something different for the new interior. Quote Link to comment Share on other sites More sharing options...

Then 95 has something different for the new interior. 1994 is 1994 only due to the airbag. 1992 3.1 CSs up to VIN 325000 and 1992 3.4 CSs got clusters with numbered and functional oil pressure gauges. later 1992 3.1 and 1993/94 got oil gauge dummy.

white4d96 Posted July 10, 2011 Report Share Posted July 10, 2011 To add a little, the 94-96 GTP cluster looks the exact same as the 3 3.1 GP cars posted, but the tach redlines at 7k instead of 6k. The 95-97 (not sure about 98-99) Z34 also looks the exact same as the 3.1 cluster you posted but again with a 7k redline. My original cluster (96 GPSE 3100) redlined at 6250; the 95 CS3100 one I swapped in redlines at 6k. Quote Link to comment Share on other sites More sharing options...
GM-4-LIFE Posted July 10, 2011 Report Share Posted July 10, 2011 thats just like the one in my 91 cutlass supreme Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted July 10, 2011 Author Report Share Posted July 10, 2011 the redline starts at 5500 and changes to 6000? neat. Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted July 10, 2011 Report Share Posted July 10, 2011 I'd be absolutely lying if I said this wasn't the whole reason I bought my '91 CS. Quote Link to comment Share on other sites More sharing options...

tornado_735 Posted July 10, 2011 Report Share Posted July 10, 2011 Nope came off an 89 international that was loaded. Maybe due to the lack of a PCM telling it what the redline should be? That's just an uneducated and more than likely incorrect guess. Quote Link to comment Share on other sites More sharing options...

That's just an uneducated and more than likely incorrect guess. actually, i'm taking a look at the diagrams now, the digi UB3 DOES(or at least is supposed to) have a connection to the ALDL circuit, so it is possible that when no ALDL chatter is happening, it defaults to 7000. the PCM does transmit the engine redline to the DIC, i imagine the cluster picks it up as well.

RobertISaar Posted July 10, 2011 Author Report Share Posted July 10, 2011 this theory would need to be tested to be for certain, but it is entirely possible, even likely since i don't know what other purpose the ALDL circuit would have being connected to the instrument cluster.

alec_b Posted July 11, 2011 Report Share Posted July 11, 2011 I remember having to splice into the ALDL ckt. for my UB3 swap in the regal. One thing I noticed different in the wiring was the digital gauges had no input for RPM, so I just assumes it pulled the data from serial. My GS, being a 3.8, with the analog cluster, was marked at a yellow line of 5k and a redline of 5500. The UB3, which came out of a 3.1 regal, had a yellow line of 5500 and a redline of 6k. So, at least in the regals, the serial data doesn't change the dash. I've never seen a 3800 equipped UB3 equipped regal so I'm not sure if it's different.

ManicMechanic Posted July 11, 2011 Report Share Posted July 11, 2011 (edited) Hollander shows no difference between 3.1 and 3800 UB3s. I don't believe they show a difference between 3.1 and 3.4 UB3s in the Cutlass either. Not sure about the Quad 4 powered cars.

RobertISaar Posted July 11, 2011 Author Report Share Posted July 11, 2011 something i was pondering on the way home from meijer: did any of the 90-91 Q4 CS models get the digi UB3? and if so, what differences were made to allow the tach to function correctly due to the difference in cylinder count? then i realized that the tach signal only gets sent once per revolution, so i felt like a dumbass for a few minutes. 10 pulses per second = 600 RPM, regardless of cylinder count. then i look at diagrams again and see no circuit coming from the ICM to the instrument cluster and realize that the RPM signal also comes from the datastream. :RAGE: Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted July 11, 2011 Report Share Posted July 11, 2011 All A code cars got the UB3. Not sure about D code cars. Quote Link to comment Share on other sites More sharing options...

RobertISaar Posted July 11, 2011 Author Report Share Posted July 11, 2011 so, aaron, looks like you stumbled onto the UB3 using the datastream to determine redline, and now it looks like RPM is pulled from there as well. i took a look at the files i have, and for a 91, a couple of different messages are transmitted to the DIS/IPC: message A(seems to be most frequent message): RPM in increments of 1 couple of status bits: diagnostics enabled, SES light, upshift light message 5: same status bits as above, plus: VATS disabled fuel system, DTCs 14,15, 24 and low coolant filtered vehicle speed in increments of 1 redline RPM sent in increments of 100 battery voltage in increments of .1 running total of time injectors have spent open in increments of .015mSec flowrate of a single injector in gallons/hour in increments of .09375 GPH and coolant temp in increments of 1.35*F now, i know the IPC gets a lot of these from actual physical sensors as well, though it may do comparing to test itself/PCM?

rockfangd Posted January 13, 2012 Report Share Posted January 13, 2012 hope this helps. the UB3 I posted was from my 94 cutlass supreme sl. Coulmn shift. The difference between the console and column shift is the gearshift indicator. Column shift has the indicators at the bottom center. and the console shift has a black plate. Both held with 2 5.5 mm screws Quote Link to comment Share on other sites More sharing options...
