Summary of change:
MembersPage/TomPhillips/TriggerPage Short description of the project I'm working on. I'm getting ready to order soon. '''Thanks for comments and suggestions''' * ''' 1988 Alfa Romeo 75/Milano ''' * ''' Alfa Romeo 164 v6 engine ''' * 3.0 60 degree even fire V6. * Two valves per cylinder overhead cam. * Motronic system stock * Stock 60-2 crankwheel VR-trigger ** cam trigger available ? '' not needed if runing wasted '' *** Ill fabricate that. I have a pickup. * intake system replaced with dual plenum system. ---- == Target features: == * 2 EGT (Not installed initially) * WB02 * active types, possibly wasted spark ** what is the exact type ? Do you know for sure it needs less than 10mA input current on the logic signal input ? *** Is the 10ma limit sufficient for typical active coils? If so I can go ahead with the ECU config I have and make final coil decision later. ** '''I'd definitely choose wasted spark coils'''. 3x higher spark energy possible, so even after 10% lost (due to wasted spark), you end up with a much more durable system that is easier to get life into and harder to kill. ** The VAG COPs are problematic (input, max output spark energy and reliability-wise), even if they are perfect mechanical fit for your cylinder head. VAG cops might be appealing with their low purchase price, but most pays a higher price learning that wasted-spark is better (except maybe for the 5cyl engines). '' only the very early coils were bad. From all the reading I have done. there was a bad lot of coil a long time ago and it was a different type of coil the type with the mounting holes. and even that type was recalled and there is new types out now. I run wasted with the VAG and the spark is a lot stronger then the acell wasted coil I have on my spider'' '' The new VAG also have a auto time-out so if they are driven for too long it will not hurt them.'' '' Either type of coil will work great but I hate to see the VAG dismissed due to a bad batch on a different coil. All the new VAG cars ship with the new coils if they were that bad it would sink VAG'' ** What about the GM LS1-LS6 style coil packs? I havent found specs yet but its another easy fit. I trying to get away from long sparkplug wires on the V6. * High Z injectors * Offboard MAP sensor ** would you choose onboard if we had 115kPa sensor option ? (we do have the 115kPa sensors, and the small daughter adapter-PCB ready soon). *** In my config the ECU will be fairly distant from the manifold and makes the vacuum hose too long. ** The advantage of onboard MAP is +1 analog input. *** Im not clear on what +1 analog means. Is that an additional volt of range? * Crank Sensor VR * Cam Sensor VR (audi trigger) -- == Assembled v3.3 controller == * PowerFlyback yes * primary_trigger VR * mounting-style screws * MAP connection offboard(electronic) * LCD and PS2 yes * Knock and EGT yes * ignition driver 2+6 * 1-wire interface no * secondary_trigger auditrigger -- == VEMS parts to be ordered with control == * 2 x K-thermocouple connector * 1 x Assembled v3.3 controller * 1 x Sealed sensor connector * 1 x Econoseal18-harness * 1 x Econoseal36-harness * 10 x Injector connector 2pin * 1 x Wideband O2 sensor * 1 x Wideband connector * 1 x LCD4x20 * 1 x MAT sensor * 3 x Injector connector 3pin -- |||| '''ECU Pin Assignments''' || || '''Function''' || '''Econoseal Pin''' || || Sensor power 5V || EC36-28 || || Sensor ground || EC36-26 || || Power ground || EC36-5 batt-gnd || || Power ground || EC36-21 batt-gnd || || Power ground || EC36-22 batt-gnd || || Power ground || EC36-32 batt-gnd || || Flyback || EC36-23 (Injector return) || || injector 1 || EC36-7 (Injector A) || || injector 2 || EC36-19 (Injector B) || || injector 3 || EC36-8 (Injector C) || || injector 4 || EC36-20 (Injector D) || || injector 5 || EC36-9 (Injector E) || || injector 6 || EC36-18 (Injector F) || || CLT || EC36-14 (CLT Coolant Temp) || || IAT || EC36-2 (Intake Air Temp) || || TPS || EC36-1 (TPS signal) || || TPS 5v || EC36-29 (TPS +5v) || || IAC PWM || EC ******* || || Crank sensor (vr) || EC36-27 || || Cam sensor (vr) || EC18-13 || || coil1 || EC36-35 (Coil #1) || || coil2 || EC36-33 (Coil #2) || || coil3 || EC36-34 (Coil #3) || || coil4 || EC36-36 (Coil #4) || || coil5 || EC36-11 (Coil #5) || || coil6 || EC36-12 (Coil #6) || || Fuel Pump Relay || EC36-15 || || Fan Relay || EC36-16 || || Control Relays (2) || EC36-30 (Injector/Coil Pwr) || || knock signal A || EC18-2 || || knock signal B || EC18-3 || || MAP (offboard) || EC18-6 || || nernst_cell || EC18-13 || || heater - || EC18-18 || || pump - || EC18-7 || || pump + || EC18-9 ||
