RogerH Posted March 29 Report Share Posted March 29 Hi Folks I have some OD controllers for both 'A' and 'J' type OD boxers. You manually select OD and the controller will deselect when you change gear. Or you can manually deselect back into gear. When selecting Neutral the controller resets to the Off condition. There is an indicator LED light with night driving dimmer controller. The 'A' type is £45. The 'J' type is £50. There is also a switch identical to the TR4/4A switch that will fir the 5 and 6. I know some folk think these are a bit geeky but they do make the driving a slightly better experience. Roger Link to post Share on other sites

dave bailey Posted March 30 Report Share Posted March 30 Hi Roger, I might be interested in one of these for my TR5 rebuild A type O/D. Is it the same as the Revington system? Sorry for being a bit thick, but what is the switch to which you refer?. Dave. Link to post Share on other sites

pinky Posted April 4 Report Share Posted April 4 I have one of Roger's logic boxes, best thing since sliced bread Link to post Share on other sites
Mk2 Chopper Posted April 16 Report Share Posted April 16 I'm not sure I'm totally getting the need for a logic box, what am I not getting here, over the standard set up of an on off switch and the inhibitor switches? Gareth Link to post Share on other sites
RobH Posted April 16 Report Share Posted April 16 (edited) Without a logic box, changing up from OD2 or OD3 takes you to OD3 or OD4 respectively. To go from OD2> direct 3rd means having to change gear and then operate the switch to turn the OD off. The logic box does the OD switching for you so you go directly from OD2 to direct third etc, much more like having a close-ratio gearbox. The on/off switch is replaced by a momentary one, either a flick switch or push button. Ie Without logic box : 2nd >switch on >2 OD 2OD >change gear> 3 OD.> switch off> 3rd 3rd> switch on > 3 OD 3 OD> change gear> 4 OD> switch off> 4th 4th>switch on> 4 OD With logic: 2>flick>2 OD 2 OD >change gear>3rd 3rd>flick>3 OD 3OD>change gear>4th 4th>flick> 4 OD Edited April 16 by RobH Link to post Share on other sites

Hi Phil, on first sight all the wires ( 7 ) look daunting. But they are colour coded and fit direct into the the car. On the 'A' type two wires are switched over on the 6RA OD Relay. Wires for the operating switch and Indicator LED need to be laced through the steering column loom About 1 hours work Forget that they are 'electric' wires - imagine they are brake pipes and it becomes easy.

For most it's little different from operating the standard arrangement except you can't go direct from 4 OD>3 OD - (but then why would you want to?) The logic box turns OD off when you change gear, so if you are in 4 OD and just change down instead of turning OD off, it goes direct to 3rd giving a lot more acceleration potential.

With the arrangement of a momentary switch on the gear knob you can actually go 4/od to 3/od by keeping the button depressed when you change down. Though as you say why would you? Stuart.

james christie Posted April 17 Report Share Posted April 17 Unless I’ve missed something the question of disengaging the OD without changing gear has not been raised. A simple touch on the momentary switch? Very useful around here on the local roads where I very often move between 3rd and 3rd OD and back to 3rd james Link to post Share on other sites
RogerH Posted April 17 Author Report Share Posted April 17 Hi James, I don't know how other boxes do it but on mine to come out of OD a simple touch of the switch. When I was in Germany, Blackforest - the straights on the hills were in 3rdOD and the hairpins in 3rd - no clutch just a simple tap of the switch IN & OUT Roger Link to post Share on other sites

In fact I might even buy you two beers. james Link to post Share on other sites
RogerH Posted April 17 Author Report Share Posted April 17 Hi James, I will certainly help install it but as a demo I think that is asking murphies law to come into operation. Roger Link to post Share on other sites
