Well, after finally programming the digital wur for the correct warm cp, the engine runs quite well now when fully warm. Better than it ever has in fact, smooth, even torque, quieter and more powerful. So far, so good ...
Now the problem is that during warm starting, the wur shoots the cp up to around 3.8 and varies it around that number for close to 8 minutes before bringing it back down to the 3.4 bar that it is set to. The digital wur representative insists that this is the fault of my car, and that it is because the system pressure is leaking down incorrectly. He states that my 81 sc should hold at least a 1.5 bar system pressure for weeks, months and even years and though my leakdowns are well over the 1.3 bar and 1.1 bar minimums after 10 and 20 minutes, those numbers do not apply to my situation.
I cannot find any literature regarding the final leak-down to zero pressure time for this car and I am wondering if anyone out there knows what I should be getting ?
Thanks
Bill
