Summary of change:
Installing Vems3.3 on a Volvo 244 with a B21ET engine. Taken out the dreadful K-jetronic to get complete control. This car should be competing this year in the Benelux Driftseries. My name is Jochen aka Brickdrifter and I'm living in Belgium. '''Current setup:''' B21ET Garret T3.60/.63 trim turbo XS Power intercooler ''' 36-1 trigger wheel with Ford VR sensor ''' IAT sensor from webshop Volvo 960 TPS sensor 1.0.45 Firmware Megatune, no LCD :-( '''Vems controls:''' - ''' ''injection (2banks)'' ''' * Ford brown top Low Z injectors with original Volvo resistor pack * Fuel pressure regulator (set to 2.5 bar) - ''' '' ignition'' ''' * Coil pack normally used for EDIS setup http://img273.imageshack.us/img273/9224/img86538ys.jpg ---- ''' CONFIG AND TABLES ''' '''Misc1out''' is used for waterinjection solenoid ''' ''Tachchannel'' would be used to drive the original tachometer but how?''' ---- * I had to set the timing on MegaTune to 32° because it's the only way the engine runs well. With the timinglight I have approx. 50°. Is it normal for a engine to have 50° ignition advance @ idle? ** No, something is wrong. * With crank advance set to 0 the timinglight shows 0 on the engine. ** something must be wrong with this measurement. ** With ign_balance=00 mda.. command sets advance where you think (mda01 is 1/4 degree, mda28 is 40*1/4=10 degrees, mda00 is advance from table-lookup); so your base timing is most likely not where you think. Remove a sparkplug to check TDC with a rod. I had the signal at non-TDC position several times * '''Checked the TDC point with a rod''' ** I've set everything to zero, including ignition map. knock_default_retard=00, so only ignition advance based idle control might interfere, but that is only +-2 degrees * Then I changed ign_tdcdelay (now 93°) so that with the timing light it showed 0. All well so far. Then I changed ign_crank_advance to 15° and the timing light showed 24°. What am I doing wrong? * ign_tdcdelay=7E below, so published config conflicts with above "ign_tdcdelay (now 93°)" ** if ign_tdcdelay=93 degrees is true, increase trigger_tooth by 4 and use ign_tdcdelay=53 degrees (4 tooth that is 40 degrees lower) ** also make sure trigger_tooth=.. is published correctly *** Up to date config and tables below with suggested increase of trigger-tooth. * There is a suspicion that bad wheelshape of the 36-1 wheel tricks you, eg. sometimes (depending on RPM) the tooth after the missing gap is lost. That counts wheel_error, but with ALLOW_SLOPPY_TOOTHWHEEL (that is default) it runs (with 1 tooth retard when tooth is lost that is 10 degrees) ** check wheel_error counter (LCD mlp01 or MegaTune log or LED) *** No trigger errors what so ever. Even if this was the case, the ignition that I check with the timing light advances too much. I set the crank-advance to 15° and timing light shows 24°. ---- Primary trigger settings - mine differ to yours: Mine: <code> primary_trigger=01 secondary_trigger=02 tooth_wheel=23 trigger_tooth=01 another_trigger_tooth=12 crank_minper=50 tooth_wheel_twidth1=0A tooth_wheel_twidth2=06 cam_sync_r_edge_phase=FF cam_sync_f_edge_phase=FF reset_engphase_after=D8 ign_tdcdelay=80 </code> You seem to have: {{trigger_tooth=00}} and {{another_trigger_tooth=12}} {{tooth_wheel_twidth2=0A}} and reset eng phase... It might be worth patching your settings with these and setting up again. //PhatBob 22-10-06: Tried but no difference. With this setup the engine only runs ok with ign_tdcdelay set in MegaTune to approx. 60° with the whole ign map set to 15°. Again, I triple checked that the engine is in TDC when the mark says so and timing light shows zero when crank-advance is 0. //VdBVolvo ----- <code> primep=00 primep_temp_scaling=03 cwl=CD cwh=19
