88Intl Posted February 4, 2003 Author Report Share Posted February 4, 2003 My old flaky one was 1.8W but my newer one is 2.1W and the engine code for it is "B6" which is for the 3.1L. This one is 1.8W, what does this display mean in Test Mode? E HO L 00 00 4 L Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted February 4, 2003 Report Share Posted February 4, 2003 E = English Mode H0 = Engine Code (B6 = 3.1L, H0 = 2.8L... weird because LB6 is 2.8L and LH0 is 3.1L, but whatever). L = Park lamps Off 00 = Dimming Input (percent) 00 = Fuel level (percent) 4 = 4004 pulses per mile L = VSS signal input Low Quote Link to comment Share on other sites More sharing options...
88Intl Posted February 4, 2003 Author Report Share Posted February 4, 2003 It's sitting on top of my PC, running off my rechargeable 12V power supply. 12v+ to ORANGE + PINK/BLK, 12V- to all 3 black wires. With that site, plus your pages here on upgrading from base to gauge cluster, with the service manual scans, this is my pinout so far which I am fairly confident will work. Not sure if the grounds are supposed to be connected to different circuits, or if the gauge cluster is the best place to hook everything up to. Does the stock DIC harness come directly from the gauge cluster?: [DIC PCB] [4-POSITION HARNESS] [MIGHT BE] B ORANGE - A ORANGE ?ALDL? L GREEN - B GREEN ?VSS? F PINK - C PURPLE ?FUEL LEVEL SENDER?

88Intl Posted February 4, 2003 Author Report Share Posted February 4, 2003 H0 = Engine Code (B6 = 3.1L, H0 = 2.8L... weird because LB6 is 2.8L and Pretty sure the donor car had a 3.1. The bug with these early rev DIC's is low fuel economy reading, which was fixed by a firmware or MEMCAL upgrade, right? Possible the problem was that firmware or MEMCAL designed for 2.8's was being used with 3.1's, and that it will work fine with my 2.8?

Brian P Posted February 4, 2003 Report Share Posted February 4, 2003 Odd, because the DIC I got from a '91 sedan has the 2.8 code, i THINK. zzzzzz....too lazy to go back outside. I think the problem with the older DIC's was a reading TOO HIGH of fuel economy, or so Ive heard! Quote Link to comment Share on other sites More sharing options...
