      Hi Dave!

      It is rare that a computer fails in a Cadillac and I have never personally had to replace one. I would say that a computer is one of the very few objects that I would buy from a salvage yard just because they never seem to fail but I guess that they a hard to come by since the car is fourty years old.

      Other sources/solutions would be:

      1) have the mechanic to replace the computer at no additional cost, they messed it up...

      2) Ebay, Amazon etc. Google it. I suggest that you find out what engine option the Eldo have to be sure to find the right part. I found this info: Problem with 1981 Eldorado ECM and PROMS (cadillaclasalleclub.org)

  2. Started the engine tonight after sitting for 2 years after charging battery started up with bad miss. I will be repositioning the car in the drive in the morning and covering with large tarp to start disassembly.
  3. I f any of you guys have a set of the Cam bearing index tool from Kent Moore 6686 I would love to get the measurement of the two plate tools. Gap and distance. If I pull down the motor before the measurement I will make the tool by measuring my engine and post the drawings here.
  4. Started Designing some of the Tools for this Build Today Happy Easter. As I weld and I am an advanced fabricator Machinist engineer type. I wanted to do this build out of my home garage however My race car sits there so I am building in the driveway under a big Live Oak Tree. Message me for the sketchup file it is just over 207K zipped. So this is a design for the body lift based on a hydraulic ram driven Rhomboid with telescoping rear supports. To use I plan to first jack stand the car wheels off and slide under the body, clamp the pinch clamps to the body jack seams an
  5. This is the kind of great stuff I like to build. I will be watching for interest as I build EFI controllers how big is the Northstar demand for controllers anyhow? There are a lot of electronics that really need upgrade on these motors while the engine is an engineers motor the ignition and fuel is difficult for the after market. I have seen Cadillac Motor Sports guys put together kits that use the DIS systems from LS motors on carborated blown versions of the northstar. I recently built a prototype for 600Hp LT-1 Chevy motor in my garage but have not tested it or started t
  6. Great idea I have a set of these Kent-Moore J-44212 GM Northstar Camshaft Holding Tool Set I will measure them and leave another tip in my upcoming build thread.
  7. These issues with can bus data bus from individual components is very true. One unusual solution is to record the can bus and look for signals that relate to the various modules. You can use several different can bus hacking tools from the webs. Once you dial in the expected call and response you can use an arduino and a can bus adapter to emulate the needed response I did this after upgrading my seville to Air ride when the magnaride controller locked out the 80MPH plus. With these older vehicles the computer hardware is so outdated your phone typically has much more capab
  8. rockfanged stole my thunder but you can find the seat heater power connector and thermister connectors under the seat pad bottom. You can use a simple relay and switch set up or build in a separate zone temp controller using https://www.mpja.com/Digital-Temperature-Controller-Thermostat/productinfo/32709+MP/ dual zone thermostat and some sheet metal work on the dash.
  9. HI ALL NEW TO THE FORUM I am about to start on a rebuild of my Seville STS. The items to be done or redone are as follows. I have an extreme stress job all mental so build the next two cars is my physical release of stress. To start with I have a blown gasket and a collapsed lifter. My spouse continued to drive the car and cracked the transmission cooler in the radiator flooding the engine with trans fluid and the trans with coolant. So pretty much toast. I have previously upgraded the brakes with Stage III Power Stop rotors and pads works nice but after sitting they r
  10. I did a Brake Mod to my 2002 STS Seville a few years ago. I found a company called power stop has excellent cross drilled slotted rotors and much more aggressive pads Really reasonably priced around 100 usd per axle. Thought of upgrading to the large disk like this post as I had a CNC to make adapters but found when testing I had issues with the ABS triggering too early. I have the dreaded head gasket problem and the car has been sitting for three years now due to my own illness. Recent improvement in health has enabled me to return to work so my Seville is getting the mu
