Summary of change:
Now we have a new problem, we have installed the ECU in our car, and our 2 trigger is quite noisy when the coil fires.. Out two triggers are located in the distributor so there are plenty of noise from the ignition coil! The primary trigger signal is total clean, but the second isnt. Our 1 trigger is on 572 ohm and the 2 trigger is on 280ohm. We tryed to insert a 1k ohm resisor across the + and on the sensor but it is still very noisy.. I have 3 files for you: One trigger log whit the ignition coil connected: http://www.vems.hu/files/Racezone/v3.3_n002831-2011-07-28-18.15.08.triggerlog One trigger log whit out the ignition coil connected: http://www.vems.hu/files/Racezone/v3.3_n002831-2011-07-28-18.20.21.triggerlog And my vemstune setup file: http://www.vems.hu/files/Racezone/Daniels%20Carina,%20ikke%20startet%20endnu.vemscfg Any Ideas for hardware mods? UPDATE:: I got some scope pictures, as you can see the ignition coil is making some noise ( aprox 200mv ) http://www.vems.hu/files/Racezone/Noise%203sfe.jpg How to fix ? Regards Daniel _______________________________________________________________ Hello, we are planing to build one of our private cars whit vems Our goel is to make a PnP install. Q: Our only concern is about the trigger! Our car is driving whit a 4 + 1 trigger system. The 4 triggers comes 10 degress before TDC, and the cam sensor trigger comes in TDC for cylinder one.. Is that posible ? A: This trigger is easy, but you must use VemsTune to make a triggerlog and check the timing of the primary and secondary trigger pulses. The cam sync must always appear between the same two primary trigger events, if not then you will see "sec trigger late/early" in VemsTune and datalogs. You can try offsetting the signal using the trigger edge setting for both or either of the triggers, change from falling/rising to the other will offset the signal by a trigger tooth width. //Mattias Q: Great. I took the scoope picture here: http://www.vems.hu/files/Racezone/Trigger%20billede%20carina%203sfe.jpg The Sec trigger occur at TDC on cyl 1. The primary trigger occurs at 15 degress before top. Kind Regards Daniel
