Re: US over to europan.

As usual you twist what is fact and what is true, in an attempt to prove a theory, which is wrong. Forget the percentage jargon. Confine actions to the binary. All else follows. Inserting the fuse results in exactly the same control signal, in respect of the orientation of the pulses, as when normal control is functioning. The difference you describe is not in fact required. This is a figment of your imagination, alight as a means of justifying another fairy story. The signals do not require turning back the right way. They are the right way. The signals are the same for both TCU. It is the final action which takes place, as a result of the signal, which is different in the two systems. The same signal achieves the same result due to the use of a different orientation of valve in each system. !. A lengthening pulse energises the solenoid and extends the armature. 2. A shortening pulse allows the armature to retract. 1. Closes a N/O. valve. Opens a N/C valve. 2. Opens a N/O valve. Closes a N/C valve. It is the relationship between the non electrical controls which requires “reversal” , and the difference in solenoid valve configuration achieves the required result. N.B. This relationship will mean a second “reversal” and therefore, no reversal, in the event that your theory is applied. Normal VTD system. --- When increased front bias is required, (Or the fuse switch fitted to provide a locked up drive.) the pulse length will be increased, (Or a constant signal transmitted.) in order to close a N/O solenoid, thus increasing pressure, to close a LSD clutch. The TCU will be programmed to increase the pulse length. With Alex' car. --- When increased front bias is required, (as when inserting the fuse switch), the same increased pulse length command, (or a constant signal) will open a N/C solenoid, thus reducing pressure, to open the centre clutch. The TCU will be programmed to increase the pulse length. Think about it.
