98Concours Posted May 16, 2004 Report Share Posted May 16, 2004 Is there a way to override the ipc on a 95Concours so that I can show the coolant temp and perhaps the rpm on the DIC? I've done it on my 98 Concours and you change the value of IPS05. The 95 doesn't have IPS05, but does have a value of 85 on IPS08.

The_Raven Posted May 16, 2004 Report Share Posted May 16, 2004 Howyadoin, Here's the info... Be VERY certain that the sequence is as written, if there's a mismatch on anything beware, as this is not specifically for a Concours... I used this on my '96 SLS and was successful. Thanks to bela for this information... "'96 and '97 STS programming... Ignition is on (motor may or may not run). Press and hold the [OFF] and [PASS WARMER] buttons simultaneously on your HVAC panel until the 'light show', a.k.a. segment check. Then watch the DTCs, if any, to scroll by, and then it'll stop and displays 'PCM?' on the DIC. Skip that by pressing [FAN DOWN], and keep skipping until you'll see 'IPC?'. Select this one by pressing [FAN UP]. Skip the menu options 'IPC DATA?' and 'IPC INPUT?', and select ( [FAN UP] ) 'IPC OVERRIDE?'. In 'IPC OVERRIDE', its various options with their numerical value in the right hand side corner of the DIC will then be displayed. Skip each one ( [FAN DOWN] ) until see Option E, which is IPS05. You'll see a number ( 43 is the factory preset value) on the DIC. Increse that number by 68 ( 43 + 68 = 111) by pressing [PASS WARMER]. The DIC will display the new number. With [PASS COOLER] you can decrease that number, in case you've overshot. Store the new value by pressing [A/C] and [FRONT DEFROST] simultaneously until the new number (111) on the DIC blinks once. Exit diag mode. P.S.: Anybody can explain why it's NOT possible to display RPM on the DIC on analog clusters? The argument of redundancy, i.e., that you already have a tach, does not hold water because one can display MPH and we do have a speedo. -Bela" P.S.

Luke Posted May 16, 2004 Report Share Posted May 16, 2004 My 1993 STS displayed the RPM in addition to the analog tach. It was that way when I got it. I can't really explain that car though. It had a 1992 STS style muffler also. Also, it had more power and low end torque than any other Northstar I have ever driven. It was downright wild! I miss that car.

98Concours Posted May 16, 2004 Author Report Share Posted May 16, 2004 Thanks Rav, but the 95concours doesn't show a IPS05. It does show a IPS08. I wonder if that is the same thing? Jeff Jeff 98 Concours 90 Seville 04 Corvette Link to comment Share on other sites More sharing options...
The_Raven Posted May 16, 2004 Report Share Posted May 16, 2004 Howyadoin, Hmmm... I wouldn't be in a hurry to test that theory. IPC programming mistakes can be painful. Sorry the info wasn't the correct version. -Rav -Mark P.
