    Brake Booster failures on Discovery I

    PS. My theory is that all of these standard replacements may have been sitting on a shelf since the 90s and the rubber parts are failing due to age. Sound plausible?

    Brake Booster failures on Discovery I

    My first brake booster lasted for 275K miles and 25 years. 2 replacements have failed in the last 5K miles in 1 year. First replacement was new but of unknown origin. Second one came from England and billed as the best replacement. (While it lasted it seemed to work as well as the original). Any...

    1996 Manual Transmission ECU

    I’m pretty sure it is true that the tune number deals with the those adjustments differently for the manual. It looks like tune # 9630, 9644 and 9653 are all the manual transmission tunes. I am currently trying to determine if the corresponding EPROMs can be copied and duplicated.

    1996 Manual Transmission ECU

    Interesting. Unplugging the stepper motor (IAC) is a similar solution. It is the only way the ECU can directly adjust the idle speed.

    1996 Manual Transmission ECU

    As you probably know, some of those idle issues could be vacuum related. If you unplug your IAC (stepper motor) while it is running and leave it unplugged, any erratic idling is not related to the ECU. This is how I run mine except in the summer when I need to use the air conditioner. PS. it is...

    1996 Manual Transmission ECU

    I am learning as this thread progresses. One thing I am now convinced of is that setting the software switch from automatic to manual will not change the “tune level”. I am fairly convinced the 5-speed ECU needs an eprom that matches one of the manual tune levels. (Later ones than originally...

    1996 Manual Transmission ECU

    I am curious about what caused your idle issues. Was your ECU replaced or was it something else? Do you know the revision level of your ECU?

    1996 Manual Transmission ECU

    Since it was from an ael truck, the eprom probably was after the early revision. I’m still surprised it didn’t have to have the transmission settings changed. Any chance they were updated when you installed it?

    1996 Manual Transmission ECU

    Could be, but there are clearly at least 2 ECU settings that indicate whether it is a manual or automatic. Also, I know there was an eprom update specifically to address issues with the 5-speed. Maybe yours has the update and mine doesn’t. Mine probably is also set for an automatic.

    Faultmate MSV-2 w/ GEMS multivehicle license

    Thanks. Let me know if you think you can. I probably will want to leave the one I have installed and let you try to change another one. As noted earlier, there was a revision to the eprom specifically to address issues with the manual. Would like to make sure the one changed is at a high enough...

    I am looking for an ECU for a manual transmission 1996 DI. I understand there was a recall replacement eprom to address idle issues. This is what I need.

    1996 Manual Transmission ECU

    If you depress the clutch pedal in motion, revs do not drop below 1500/2000 rpm. It drops to normal 650 idle when it comes to a dead stop. Caveat: if you ride the engine down to about 1100 and then depress clutch it also will drop to normal idle. Pumping the brake pedal will slightly raise...

    1996 Manual Transmission ECU

    Don’t know if the ECUs were labeled to indicate transmission type or recall replacement.

    1996 Manual Transmission ECU

    My 1996 has 275K miles, all with me in the drivers seat. Replaced first clutch at 250K. I was told by a knowledgeable person just this week that there is not any linkage between the ecu and the security system. (I specifically asked that question). I don't know; but could probably find out...

    1996 Manual Transmission ECU

    What is the 10AS? ECU appears to be doing what it thinks it is supposed to do. However, it clearly is telling the stepper motor how to handle an automatic. Don't know what else it may be doing wrong for a manual. PS. "1998 D1 LSE 300TDI R380, 1996 D1 SD R380 4.0" You have a 1998 with the...

    1996 Manual Transmission ECU

    I have a 1996 DI with manual transmission. Had a problem with the ECU and local shop installed a replacement and trashed the original ECU. It did not take long for me to figure out that I now have an ECU for an automatic. Any suggestions on how to program one for manual transmission or where to...
