Chrysler Magnum 5.2L V8 engine wiring. Engine is running. (V8 has nice sound). Some texts are in Hungarian
ignition output - currently using 1 distributer
Ignition coil primary is connected between:
- EC36/36 ign coil-
- +12V
Fuse (BiztosÃték fontos!): 4-7.5A
Sensors
- primary trigger HALL (8 window on crank), EC36/27
- Nr of tooth on wheel: 16
- edge: falling, 50 degrees TDCdelay (verified with strobe)
- secondary trigger HALL (1 window on cam), EC36/13
- edge: falling
- internal MAP (csovel csatlakozik a MAP)
TPS sensor
- EC36/1 TPS signal (this was only wrong in the sent .xls or connected wrong ?)
- EC36/29 TPS +5V
- EC36/26 TPS ground (signal GND)
Stepper outputs
coil1: (resistance= ?)
- EC18/..
- EC18/..
coil2: (resistance= ?)
- EC18/..
- EC18/..
4 vezetékes léptetomotor tekercsei kimérhetok: A-B C-D szerint kell bekötni az EC18-ba.
- Stepper A EC18-pin4
- Stepper B EC18-pin10
- Stepper C EC18-pin5
- Stepper D EC18-pin11
Ezután csak 2 variáció marad. Ha az iránya szerint fordÃtottan reagál, akkor vagy az A-B megfordÃtásával, vagy szoftveres konfigurálással orvosolható.
Firing order
- [Cylinders were numbered] from the front of the engine to the rear; cylinders 1, 3, 5 and 7 were found on the left (driver side) bank, or "bank 1", with the even numbers on the other bank.
- verify from the cast aluminum manifold (yes, it's in the casting, look hard, look in all 8 branches).
- Firing Order: 1-8-4-3-6-5-7-2 same as listed [here]
- verify from the distributer order !
- Engine Type: 318 cid 90' V-8 OHV
- Bore & Stroke: 3.91 x 3.31 in..(99.3 x 84.0 mm)
- Displacement: 318 cu.in. (5.2 L)
- Compression Ratio: 9.1 :1
- Lubrication: Pressure Feed - Full Flow Filtration
- Engine Oil Capacity: 5.0 Qts. (4.7 L) with Filter
- Cooling System: Liquid - Forced Circulation - Ethylene Glycol Mixture
LCD - GenBoard/BuildProcedures/LCDconnect
- DSUB9 / 5 is GND.
- verify that the header pin it is connected is 0 Ohm to EC36/26 (rádugás ELŐTT ellenőrizni, hogy a EC36/26-ra fog menni)
Install initial steps
- download http://www.vems.hu/download/v3gui/
- vemstune 2010-04-28 (not 2009-10-02)
- if things don't go smooth, we'll need to try different version, but let's start with this
- install RS232 driver. if pl2303 than prolific.com.tw
- even if it was COM4 it might change when USB cable inserted into other USB port (see windows device manager, com ports = eszközkezelo)
- http://www.prolific.com.tw/eng/FAQs.asp?ID=50
- http://www.prolific.com.tw/eng/downloads.asp?ID=31
- [Cable\PL-2303\Drivers - Generic\Windows\allinone\PL2303_Prolific_DriverInstaller_v1210.zip v1210driver.zip]
- TerminalProgram - to verify RS232
- [Bray-terminal] is very good (hyperterm is very bad) but any could work.
- 9600,8,n,1 (flow control: off) Choose comm port, Connect, Type "Man mdv mdV mci" as an experiment
- even if these
- start VemsTune
- set serial port (might need to restart vemstune)
- take note of the firmware version (firmware info)
- Tools / firmware / upload firmware 1.1.75 (non-PS2). (because firmware 1.1.27 somehow misfired for the slightest noise on testbench)
- download this [initial config]
- upload config (select the just downloaded file)
- reboot
- verify MAP (must be 101 kPa)
- MAP calibration: select MAP sensor range 104, 250, 304 or 416 (so MAP is close to 101)
- finetune MAP sensor offset (so MAP=101)
- verify TPS:
- from 0 .. max
- write down min and max TPS values
- verify that angular width of tooth is 180 (in the old vemstune that means 45 degrees, tooth_wheel_twidth1=B4)
