I am looking for the location of the Gearbox ECU and the Gearbox chip to get the Bosch Numbers from them.
I have searched here under Gearbox ECU, Gearbox ECU Location, looked through the PDF Bentleys (Section 610-1) which has the locations of fuses and relays along with the E-Box and I cannot find a reference to it. I also looked in the electrical diagrams but my PDF Version is incomplete it stops at 26-EWD (Power Distribution 1994-95 525i & 525i Touring (2 of 5))
I cannot find a reference to the Gearbox ECU or the Gearbox chip neither the location or what the prefix of the numbers would even begin with.
The reson for this is that I am currently in email correspondance with Kevin Bird from Birds Auto in the UK to see if I can get the Hartge 'SwitchLogic' control unit for the 540. It was part of the kit if you upgraded your 540 to an H5 which was a capacity increase to 4.7 Litres (boring out the block from 89mm to 92mm and increasing the stroke from 80mm to 89mm, raised compression ratio from 10.0:1 to 10.5:1, head work (port matching and unshrouding the Valves, camshafts reground (Don't know what the specs are for these) This would bring the power from 286 BHP up to 340 BHP and the Torque from 294lb ft to 361lb ft. The SwitchLogic control unit, upgraded brakes, Hartge 18" Wheels.
There is currently one for sale at Birds (http://www.birdsauto.com)
Specs: 09/93 Build 540ia, Right hand drive, 109,258Kms ESC+TC, LSD, A5S-560Z Transmission.
Cheers!
