Since then I had a Maserati biturbo and so I was more involved during my spare time with mechanics than with electronics or software. Hopefully the car is 200km from where I live ! http://i23.servimg.com/u/f23/15/63/46/75/mase2_10.jpg This car is 6 cylinders odd fire, sequence for ignition is 150°-90°-150°-90°-150-90°. Triggers are 6 pins (30°-90°-30°-90°-30°-90°) on crank pulley, 2 pins on cam pulley 25° apart. There are 2 ECUS: one Microplex Marelli for injection and one IAW Weber Marelli for injection. For distributorless biturbos starting MY 1994 the cars were equipped by Maserati with 2 ECUS, each one managing injection and ignition for each 3 cylinders bank which are then even fire. The triggers for each ecu where 3 teeth on crank and 1 tooth on cam. Some information about the ignition and injection system from Enrico's site http://www.maserati-alfieri.co.uk/alfieri155-8-electr As you can see the Ignition ECU interface is quite simple: * inputs: crank and cam triggers,pressure kpa, knock * outputs : driver to coilA, driver to coil B, solenoid boost valve see also the ESjaavik's Maserati page MembersPage/ESjaavik and MembersPage/FPhil/CoilTypeOddFireConfig 02/04/2011 I made a .wav file for testing https://docs.google.com/leaf?id=0Bzteg8lQJZdWYmQ3ZTA3YjctZGY5Yy00NTc5LWE1OWQtOTljMmY5YjRkYTg1&hl=en&authkey=CJTa1IoG. '''Q''' Does anyone know if Vems firmware is able to track this profile? '''A'''This is great, Marcell has opened a new odd fire 6 cylinders page !! ;) http://www.vems.hu/wiki/index.php?page=MembersPage%2FOddFireSixCyl" '''What do I aim first?''' * Fit Form and Function : Make the Vems to substitute the Marelli Microplex ECU ignition with same ignition mam : . * Be capable with appropriate tools to verify this FFF specs. Could you contact me by email Phil? You'll find the address on my page. MembersPage/ESjaavik .
