Visit Preferences to set your user name Summary of change: '''Ignition on a Mini-Turbo (No injectors)''' Maximum planned boost is 0,8bar = 11,76PSI = 80Kpa, so max MAP reading will be 180KPa. Planned rev limit is 7500 RPM ---- '''Project state''' '''DONE''' * connected all the wirings and sensors to the engine, diagram can be seen here: MartinFranck/Wiring * document what is done - eg. trigger position and ignition channels * complete config.txt * have config.txt reviewed * upload config.txt to GenBoard * some table-testing wouldn't hurt (!) * fire up the engine, whit succes 18/3-05 :) * Check that the VR sensor position is correct. '''TODO''' * Get the Tachometer to showe correctly RPM . * Calibrate the air temp * Check ignition advance when boost begins ---- '''Sensors''' - already mounted: * Knock-sensor * Map-sensor standard sensor that comes whit V3-controller * TPS-sensor * Water-temp * Air-temp * Coilpack (wasted spark) and Trigger sensor from the Ford EDIS system (not using the EDIS4 modul). ---- '''Trigger''' * 36-1 crankwheel (Home made one can be seen here) and VR sensor placement can be seen here MartinFranck/Pictures '''The primary trigger input channel must be set up with the relevant jumper to VR-type input (so LM1815 is used)'''. I have uploaded new and better pictures of the board, they can be seen here: MartinFranck\Pictures * you have to short SJ6 (right below LM1815) by soldering * put a jumper (or rather solder, preferrably on bottom of the board) to short JP2 and JP7 : viewing from the "Top" side, connect the upper-middle pin to the upper-right pin of 3x2 pinheader (between the EC36 and the LM1815). Make sure you view the board in a good orientation, so econoseal points down and "Top" text is readable (not as on you pictures). If you view from the bottom (because soldering on the bottom), connect upper-middle to upper-left pin - obviously. -------- '''Ignition''' Wasted spark: 2 channels for 4 cylinders. * 1 and 4 fire together (PIN 35, h[2] value 00) * 2 and 3 fire together (PIN 12, h[2] value 05) I can´t figur it out with the starting dwell, I have looked on DummyIgnition. But if I start carefully with 2.5 msec, is´nt that okay too start with? 2.5 msec x=2500/64 x=39 Hex(39)=27 so: ign_dwelll4=27 # hex(27)=dec (39) ; 39 * 64 us = 2500 us dwell ---- '''Pin connections and h[2] table''' Pin connections can be seen here ..... Some very important settings like * h[2] table h[2]=05 00 05 00 05 00 05 00 * trigger_tooth * the missing tooth are at the same mark as the top mark on the engine block and that is TDC point of Cyl 1-4, because they are in top position, this is 93 deg after the VR trigger. * so isn't the missing tooth = trigger_tooth * ign_tdcdelay (0xBA*0.5 = 93deg) ---- '''config.txt''' http://www.vems.hu/files/MartinFranck/MFConfig.txt * ign_tdcdelay=BA (to reflect the 93 deg. BTDC, which is 200 decimal because of 0.5 degree resolution. This is important. * trigger_tooth=00 (0x00 means the missing tooth) ---- '''Ignition advance table''' described in the n[ ] table (8x8 or 16x8) Obviously, lower ignition advance is needed at highy MAP (> 100 kPa is possible because of the turbo). This means n[7] will hold lower values than n[0] The following kpa and rpm ranges could be used (or other can be good too): r[0] = 07 ... <5 RPM values of your choice> ... 40 48 '''(Also which format is the numbers)''' k[0] = 18 40 64 90 B0 ... <2 values of your choice> .. FF '''(18 40 64 what is these numbers in e.g Hex ?)''' ---- You can take a look at my table file, it has plenty of hints should be enough to get you going: http://vems.hu/files/DaveBrul/tables.txt - DB ------------------------- '''Question''' '''Q''': Have I understood it correctly, that if I want the ignition advance too be 30 deg, that i then should multiplicat with 2, so that I should write 60 deg = 3C '''(Is this correct)''' '''A''': That is incorrect, the timing unit of the ignition map (n) and ign_crank_advance is 0.25 degree. Therefore, 30 degrees = 30 x 4 = 120 = 0x78. ------------- '''Q''': When I try too comunicate with the V3-controller true megatune I get the folowing message Controller voltage too low for reliable FLAS-BurnÃng But I have trie too use a separate power supply (220v-12v), but it do not help, what can be wrong '''A''': Some people have had problems with operating a v3 controller with computer power supplies which are ~1A. You may need to try with an actual automotive battery. '''Tachometer problems''' '''Q''': Tachometer problems, my tachometer does not showe the correct RPM because I am using wasted spark, can I connect the Tachometer to the V3-controller an get the correct RPM, ore are the other obsentions ? '''A''': How is it attached right now? You should use an unused ign channel pin on EC36. I see you use two wasted spark coils, attached to EC36-34 and EC36-36, and that its a four cylinder. Attach the tach wire to an ignition output, and your add the value for that channel to every fourth h[2] array element. The Tacho is conectet to the wiring from Pin 12. My h[2] tabel is curently like this: h[2]=05 00 05 00 05 00 05 00 The wasted spark coil is cornectet too pin 12 (cyl 2-3) and 35 (cyl 1-4) If I have understood you correctly the h[2] should like this if I use ign channel 01 h[2]= 05 00 01 05 00 01 05 00 '''correct me if I am wrong''' '''A''': I think that is correct; can anyone else comment? '''Q''': If I connect it like that, will the ignition fire correctly? How does you normally connetct the the Tach on a 4 cyllinder engine when you use the settings that I use?
