Summary of change:
== Ignition == Early 16v Renaults have a cam mounted distributor, driven by a single coil. The coil has an integrated ignition amplifier with three pin and two pin connectors wired: Three Pin connector: * Pin A - +12v feed, on with ignition. * Pin B - Ground. * Pin C - Tacho signal out. Two Pin connector: * Pin A - Not Connected. * Pin B - Ignition control. When the ignition control is disconnected from the ignition module it reads +5v. When it is connected to the ignition module it reads 0v. Scope traces show the ignition pattern on an idling car: http://vems.hu/www.vems.co.uk/VEMSTech/Renault/cliorunning.png http://vems.hu/www.vems.co.uk/VEMSTech/Renault/cliorunning3.png Later Renaults have a 60-2 trigger pattern flywheel and use a Sagem wasted spark coil pack. == Triggering == Early EFi Renault engines came with an unusual trigger pattern on their flywheel. 20 teeth followed by one tooth twice the normal tooth width, followed by a missing tooth twice the normal tooth width. This pattern occurs twice to indicate TDC & BDC. A trigger log of the flywheel has been made: http://vems.hu/www.vems.co.uk/VEMSTrigger/RenaultToothTimes.txt Using the Examples from http://www.vems.hu/wiki/index.php?page=InputTrigger%2FTriggerLog <code> ... .... 455 4416 # long 457 2929 # long 459 1835 461 1838 463 1866 465 1834 467 1822 469 1822 471 1844 473 1815 475 1803 477 1836 479 1799 481 1799 483 1801 485 1831 487 1802 489 1811 491 1847 493 1813 495 4480 # long 497 2873 # long ... one crank rotation later position 495-455 = 40 499 1837 501 1829 503 1840 </code> Looks like a 22-2 teeth pattern (20 tooth: the 40 difference is normal, comes from the way the log is made), but inverted. This works with standard config using a 20 tooth primary trigger setting. Cranking shows a good RPM signal, config info will be posted once the car is running correctly.
