Summary of change:
'''Nicke Nymans BMW E21 M20 Turbo''' [http://savarturbo.se/stuff/images/nicke_e21_tic/PICT0884.JPG Picture] ---- A page about how I fixed the missing boot loader after we replaced the AVR (why? long story) : MembersPage/MattiasSandgren/NickesBMW/AvrBootCode ---- '''Genboard specific configuration''' This is a v3.2 with production number 127. Both triggers are configured for Hall. Ignition outputs ||00||IGBT (Currently used to drive an MSD 6A)|| ||01||IGBT|| ||02||IGBT|| ||03||IGBT|| ||04|| SDA (PD1) - on JP1 connector (current default for AntiLagSystem)|| ||05|| SCL (PD0) - on JP1 connector || ||06||IGBT|| ||07||Ground for SCL and SDA || EGT - only first input used. LCD and PS2 - are brought through a DSUB25 as described here : GenBoard/BuildProcedures/LCDconnect MAP - MPX4250AP 250kPa=2.5 bar (1.5 bar boost) using a push-in connector in the front plate. Injector driver flyback - GenBoard/Manual/PowerFlyback '''Q''': Is [http://www.vems.hu/files/MembersPage/MattiasSandgren/sda_scl_wired_to_igbt_pins.jpg this] wiring method for SDA and SCL signals a stupid move? I'm thinking of running by the IGBTs in use. Currenly only one ('00'). * should work, but ** why not shorter traces, at the endplate side of the board (instead of the econoseal - frontplate - side) ? *** I thought why not use the Econoseal connector ** secure the wires with hotmelt, to avoid breaking due to vibration *** You can see blobs of hot melt in the picture in at least three places. What is the brownish (slightly burnt?) GND5 at the non-used IGBT position at the lower right corner ? Nothing burnt.. must be something you can see and I can't.
