Summary of change:
''' Engine specifications ''' * 4 cyl, 16 valve DOHC * Standard B202 Saab block * Stock head, slightly ported * Cams from T16 * Large turbo * Fuel of choice is E85 ''' Engine management specific information ''' * Ford Motorsport 1600 cc/min injectors * 18 V TS diode used on flyback * Distributor ignition * MSD 7AL CDI box * Dual solenoid Bosch IAC valve * Coolant fan relay * Water pump relay (radiators in the trunk) ---- ''' 2008-03-19 ''' Engine was started with fuel injection for the first time, VEMS Genboard only controlled ignition and datalogged earlier and carburators were used. Idle air valve seemed to work quite ok, but needs lots of tweaking of course. It could handle the coolant fan current draw just fine. At idle the car needs only 1.0-1.1 ms pulsewidth from the injectors. We suspect we have poor control, injectors are big but Emil suggests trying another 18V TS diode in series with the one we already have. ---- This trigger wheel (2 teeth on iron/steel disc)is in use, works fine. http://savarturbo.se/stuff/images/gustavs_saab_quattro/trigger_skiva.jpg ---- Here is the car, work in progress, just painted after all body and chassis work: http://savarturbo.se/stuff/images/gustavs_saab_quattro/lackad_2006.jpg ---- ''' The story of Genboard v3.2 #204 ''' It has seen use in a Volvo PV : MembersPage/MattiasSandgren/VolvoPV \\ It never worked quite ok on that car, blew a few injector FETs and drivers.. long story. Emil sent the board off to be repaired with new FETs and FET drivers, and it was never tested with anything connected to a FET after that. Gustav bought the board and tested it on his SAAB, ignition only, and it worked very well. \\ When it was time to try injector it didn't turn out too well. As soon as the power was turned on, the injector outputs went active by default, instead of the normally inactive state. '''We have replaced the non-inverting drivers with regular MC33151D inverting drivers (that are supported by VEMS firmware/application code).'''
