Andrew,
I have the same setup on mine i.e L76 with E38 and my fans run all of the time. I remember the tuner had great trouble trying to get them to come on at an appropriate temp, but they just stayed on. So no biggie there.
Pretty certain mine does not use the brake and clutch inputs.
Speedo- not sure on that. Sideshow did my wiring of GM harness.. Cant remember if i have that wired into the ecu...Sorry that doesnt help.
Also a note about that new cam..You will have to run it in at less than 2500 rpm until at least October 5th... weird that it specifies a date...

Does the ECU need brake and clutch inputs? Ive never had them as Ive assumed they were just used for cruise control and "clutch to start" options, however, I read elsewhere they are needed.
Fan wiring - Fans run all the time, not a big deal as you cant hear it anyway, but anyone else have this problem. I suspect it could be the lack of A\C throwing up a fault that makes the fans run, however, no fault showing on the ecu. Fan comes on when running , not just when ignition on, so it is switching from the ecu.
Speedo. ECU not getting a speedo signal. I piggybacked the feed stright to the speedo and it works fine, but without a speed in the ECU I cant get the reverse lockout the work. Any tricks I may have missed. Its basic VZ Commodore, witht he VSS input on Pins 71\72 on X1 connector. I have have them reveresed, could that be it?
Cheers
