Summary of change:
Subaru questions (TODO: make a proper project page for it, text ordered chronologically instead of thematically is likely to be neglecetd). __JDM 2001 avcs sti engine__ the trigger setup on the car is: primary VR 36-2-2-2, and secondary VR is a 2pulse on the left ontake cam, I would like to run the car with avcs fuctioning,so there is a VR sensor on both the left and right intake cam. '''secondary trigge''' * NOT connected to the 2pulse cam trigger, but instead to the right intake cams 4pulse setup(like written on the 36-2-2-2 page), The engine can run wastedspark. '''Third trigger''' and the [ http://vems.hu/vt/help/v3/v3_camshaft_angle_control.html 3rd input trigger] is on the left intake cam 4pulse trigger, ---- * What is totally unclear is what is in the dropdown menu in vemstune? ** What dropdown in which dialog ? * I believe we need to change to use the setup like oe ** primary trigger=crank 36-2-2-2 ** secondary 2 pulse on front "left" (intake or exhaust?) cam *** position of pulses ? *** does the position change when the cam is actuated ? (I guess no) ** + measure the 2 "rear" (??) VR sensors just for AVCS feedback ** intake + intake or intake+exhaust ? *** '''position of pulses ?''' *** I guess the position changes when the cam is actuated (?) IS THIS POSSIBLE ? * 1 primary-trigger + 2 camsensors (and controlling 2 independent camshafts) are possible, yes. ** the third trigger just measures the position of tooth for camshaft-angle-control (see "measure tooth" for third trigger) ** But the secondary-trigger not just measures the position of tooth but also distinguish between every second crank-rotation: *** this is necessary for camshaft-angle control (and even just to run the engine except for distributer or wasted-spark). Obviously 2 or 4 even pulses don't make this possible. 1 or 4+1 or 2 unevenly placed pulses would be suitable. BMW was smart and used 6+1 pulses to allow distinguish between every 2nd crankrot. We'll see when you fill in the above questions. * Primary-trigger + 2 camshaft-triggers are possible (both can be measured and used for controlling 2 camshafts - one each), * but primary-trigger + 3 camshaft-triggers are currently not supported (total of 4 triggers are only supported if 1 is a long HALL-pulse suitable for "masking" like in auditrigger, but apparently not the case here). Hint: make a project page, specifying exast pulse-positions (and wether they move with AVCS-actuation or not) * that makes it possible to answer the questions * "left-right-front-rear" are hardly descriptive by itself ---- d25april 2012. Am i supossed to see all 3 triggers in the trigger log with 1.1.96 firmware and subaru trigger 36-2-2-2 ?? * yes (actually triggerlog can work even for random or unsupported triggers). ** We've used triggerlogging 3 triggers extensively on BMW-double-Vanos engine [ http://vems.hu/vt/help/v3/v3_camshaft_angle_control.html see examples] ---- d.23april 2012 the cam control table in vemstune have a number range from 0-359 What is this number? On a subaru the cam advance is around 45 cam degrees,if i want the cam to be half that 22.5 degrees do i put in 180 in the table og how is this number in the table used? Thanks, Skassa ... It´s camshaft angle. If you have meassured 45deg and you set target to 50, it will try to raise the angle 5deg. If you want the target to be 22.5 just put that in the table. / Erikk **thanks /Skassa ---- d22april 2012. I´m trying to get my own subaru to run, 36-2-2-2 with acvs control. The engine have 3vr sensors, so i have purchased a vr-hall converter from the shop,But it seems that there is no output from the pcb ,other then a diveded by 4 or devided by 8 signal, and that does not work, I have been measuring the converter and it looks like there is no connetion to pin 12 on the lm1815, am i supposed to solder a wire direct to pin12 to get the signal i need? this is what i have done now, but i didnt even get from the house to the garage before the wire was broken of :( So is this how its meant to be used?? ----- || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaSubaru Start]|| [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassa%2FQuestionsSubaru Questions ]|| [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaInjectorSubaru Injector] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaIgnitionSubaru Ignition] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaTriggerSubaru Trigger] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaDisplaySubaru Display] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaWboSubaru Wbo] ||[http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaConfigSubaru Config] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaTableSubaru Table] ||[http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassawiringSubaru Wiring]|| [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaIdleSubaru Idle] || Toyota 4a-ge || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassa Start]|| [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassa%2FQuestions Questions ]|| [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaInjector Injector] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaIgnition Ignition] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaTrigger Trigger] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaDisplay Display] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaWbo Wbo] ||[http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaConfig Config] || [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaTable Table] ||[http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassawiring Wiring]|| [http://www.vems.hu/wiki/index.php?page=MembersPage%2FSkassaIdle Idle] || Hi All, Could someone please check the trigger,injector, and ignition settings, for the Subaru 6/7 trigger, to check if this can work,it´s running oe cops, so it would be great if it could run fully sequ...(cant spell that),wasted spark would also be fine!

Do You think it can be successfull ? * yes, the posted 36-2-2-2 trigger pattern was working both with and without camsync (and is still very likely to work with 1.2.x firmware) * or do I have to modify the wheels? ** no, just start a project page for your install (thematically! quickly forget this page!), and collect info like triggerlog, config, description of setup Looking forward to comparing notes on this - I have a big power 2.3 Impreza to tune next year [dnb] ---- I would like to use the knocksensor,and i have already wired it in,but i cant get any reading, how can i make one of the gauges in megatune to show noise? So i can define what noise is knock DO anyone know how a gauge en megatune,can be configered to show the noise it reads from the knocksensor?.If any of you are familer with the LINK Knocklink,you know what i mean,as this shows noise on five leds,and when running full trottle maybe 2 leds will light,but if you get knock,they all fire up , with a big red one in the top, This have got to be the part that are missing,so the knocksensing can be of great use Send me a PM/email on the VEMS UK forum and I'll send you my VEMS_v3.ini file - I have added some extra parameters to make knock logging easier. Something like the knocklink, but with more LEDs... I'm also working on a way to make tuning the knock more straight forward... More on this later when I know it works! [dnb] ---- when i make a datalog,and view the log,megatune is 2-3 degees of in advance is this normal?. Also if i in the sparktable ,write 16degree , then the advance gauge is only showing 14degrees, '''check knock_default_retard''' since knock_default_retard=08 this is correct. I dont hope that it just retard this 2 degrees,without knock,Does it do that? '''A''' Yes - knock_default_retard is a silly parameter that just offsets the whole ign table. I got caught out with this while back. [dnb] ---- there is also a big change in fuel,with inlet temp, When i have the car in idle,it can go from lambda 0.9 at around 25iat degrees, to lambda 1.1 at 45 degrees, '''After you tuned the WARM engine, adjust warmup enrichment, that is warmup_clt[]''' Or EGO needs to be alot more then 5%, to make up for this. ego rich limit at 5% is just fine once the VE table is properly tuned. It avoids a nasty positive feedback effect on rich misfire, so best left at 5% to 10%. (I note you said inlet temp, not coolant temp...) I think your IAT problem is one of heatsoak - the sensor gets hot so it reads the engine temperature, not the air temperature so it leans out the fuel due to temperature much more than it should. There is a parameter to stop this happening but I don't remember exactly what it's called. Something like "fake airden low limit". Also, the temperature sensor calibration may not be correct - worth testing this since it will induce a lambda error that is strongly correlated with temperature at all operating points. (Not good in a turbo car) [dnb]
