Visit Preferences to set your user name Summary of change: I want to use VEMS to implement the distributorless ignition on my SIII XJ12. First I'll probably build only the input part (crank trigger, MAP, air / coolant temp.) to monitor the original maps. I'd like to keep the mods reversible so I can fall back to original setup if I yield to work-wife-lack of money threat. ---- Here come the problem #1 - installation of crank trigger wheel. As can be seen in [http://aus-www.rasip.fer.hr/users/dpavlekovic/jag/img/v12_loc_ck_pulley_2.jpg this pic] there's very little space to install the 36-1 or 60-2 disc. One option is between the damper and engine timing cover (indicated with red arrow on pic). The other one is between the damper and the pulley (green arrow). '''Option #1''' There's about 7mm from damper back side to engine cover and 6mm clearance from damper to the water pump casing above the damper. The ideal shape of the trigger disc would be like [http://aus-www.rasip.fer.hr/users/dpavlekovic/jag/img/TriggerWheel_12A227-2.jpg this one] or [http://aus-www.rasip.fer.hr/users/dpavlekovic/jag/img/TriggerWheel_pressedtriggerwheels.jpg this one] (don't know how I'd describe this shape in English' - toothed-flowerpot saucer-style'?). But the diameter needs to be between 137-143mm. I haven't found one yet :( The sub-option is to have something [http://aus-www.rasip.fer.hr/users/dpavlekovic/jag/img/TriggerWheel_escort.jpg like this] machined into proper shape. This one has approximately appropriate dimensions. [http://www.omextechnology.co.uk/page3.html OMEX] produces 5mm thick 140mm diameter wheels (p/n OMEM2460). This'll also require a bit of machining. '''Option #2''' The 60-2 wheels offered by Electromotive (1/8'/3.175mm thick) could fit this gap. ==== 2005-17-03 ==== Some data from Marcell (thanks!): * 60-2 wheel from GM/Daewoo 1.6L 16valve 106HP A16DMS or A16DM - 140 mm dia., 30+ mm thick, comes integral with the multi-ribbed belt pulley. * 60-2 wheel from Opel 1.6L 8valve X16SZR or X16SZ - 140 mm dia., 20+ mm thick; integral with V-belt pulley. :Unfortunately machining is neccessary to separate tooth wheel from pulley in both cases. ---- More wheels [http://aus-www.rasip.fer.hr/users/dpavlekovic/jag/trigger_wheels.php here]. ---- Pls. add your comments 'here' or email me at: dpavlekovic at gmail dot com.
