Summary of change:
''Volvo 244 -82'' http://www.vems.hu/files/RobinJohansson/my_car.JPG 4 cyl, 16v, B234 block filled and O-ringed, forged pistons from ford probe 2.3L, forged H-profile rods, A cheap Super T70 turbo with Semi ballbearings, 60.5mm compressor inlet, 0.84 exhaust, WB lamda, GM 3bar map sensor, 4*960cc injectors, 44mm wastgate, own manifold, own exhaust manifold, lage truck intercooler and VEMS v3.1 board with serial number: 1st bord: 87 (2nd 99) BMW 535 (getrag 260) gearbox converted to fit volvo. ---- '''Page TODO''' Keep a clean page! ---- '''Current working on''' Engine running! not well but, it starts. runns very rich and nothing happens when I try adjust. Low spark power? engine keeps "blurring" and its hardly possible to change anything! When I check with timing light it seems ok... cyl 1+4 at +20 deg cyl 2+3 on the other side somewhere... maybe it could be something with config:trigger_tooth 00 is this wrong.. To get any reaction at first I had to switch cyl. 2+3 at coil to 1+4, that cant be ok!!! * Another srange thing is the WB-lamda or when I connect it, then all the injectors starts to pulsing, when engine is off! (ignition on)This happens with both of my v3.1 cards, any clues? //Robin ''Q: Which tuning program are you using? '' ''If it is megatune with vemsv3.ini-file.. This isn't working correctly.. I compiled firmware with MSNS option, and used latest megatune configured for MSNS. The problem i had with vemsv3.ini was that changing the VE-table in megatune didn't touch the table on the genboard. ignition table worked. //Emil'' ''A: I primarly edit by display/KB, but I have also made some changes by using MT with vemsv3.ini, sometims it works... It would be easier if the car was here and not in my brothers garage. //Robin '''Valued tip''' Back to tabletests: apply lightbulbs or LEDs on outputs, and see OnlineCourse/OffEngineTesting mst63 msp01 (or up to msp7E for lowest RPM) can be used to generate stimulator-output on (stolen) config.act_wot_channel output that can be fed back to self (primary trigger) or to another board - with a series cap if LM1815 is used. ---- '''Trigger wheel''' http://www.vems.hu/files/RobinJohansson/trigger.JPG Bosch VR sensor (jetronic), 36-1, mounted at crank. Trigger wheel is a castiron, 36-1 with a teethwide of 4mm->4.5deg and 5mm~>5.5deg jumps, missing tooth 14mm~>15.5deg http://www.vems.hu/files/RobinJohansson/sensor.JPG Yes, its working! I Connected pin1 to gnd and pin2 to avr and cranked, RPM shows ~170 '''Trigger signal''' Current status: * Sensor is magnetic at the top * AVR sees signal! * J1 and J6 shorted A 10uF series cap is needed so the DC signal at the LM1815 falls below 0V. Grounding the pin5 of LM1815 (switching off adaptive hysteresys mode) might be needed too. ---- '''Fuel setup''' || cyl || inj || EC36pin # || h[0] # || || 1 || A || 7 || 01 || || 2 || F || 18 || 20 || || 3 || G || 6 || 40 || || 4 || H || 17 || 80 || h[0]=80 40 20 01 00 00 00 00 h[1]=00 00 00 00 00 00 00 00 <- currently not used, during cranking the fets are fired in the 'normal' h[0] sequence - DB '''Cutout From Config''' req_fuel=28 divider=01 alternate=03 injopen=41 battfac=28 kpafac=88 kpaofs=64 injocfuel=00 injrampup_battfac=FF injpwm=0B injpwmt=B8 injpwm6=0B rpmk[0]=0B rpmk[1]=B8 tpsdot_kpadot_conf=01 tpsdotrate[0]=05 tpsdotrate[1]=14 tpsdotrate[2]=28 tpsdotrate[3]=4D tpsaq[0]=14 tpsaq[1]=28 tpsaq[2]=50 tpsaq[3]=6E tps_thresh=CC tpsasync=0A acmult=64 tpsacold=14 tpsdq=64 decel_fuelcut_thres=0F overrun_fuelcut=11 overrun_fuelresume=10 ---- '''Ignition setup''' 2 ign banks, firering a Ford dual coil with 4 outputs (Wastefire) || cyl || Driver || EC36pin # || h[2] # || || 1+4 || 06 || 24 || 06 || || 2+3 || 05 || 12 || 05 || h[2]=00 00 00 00 06 05 06 05 ''' is this right?
