Summary of change:
'''About this page''' This page covers the installation of a GenBoard/VerThree into a Daihatsu Charade GTti wich is a 3cyl 12valve Turbo car. http://en.wikipedia.org/wiki/Daihatsu_Charade ---- Config files, log files and triggerlog is found in the file area: \ http://www.vems.hu/files/MembersPage/Daihard/ MembersPage/Daihard/Partslist MembersPage/Daihard/Wiring MembersPage/Daihard/Assembling MembersPage/Daihard/Trigger MembersPage/Daihard/InjectortestDevice ---- '''Ignition system ''' The initial start will use the original single coil and distributor. Potential upgrade to coil on plug. Plug length from top of cover in CB80 GTti is 117mm . Bid on 6-BMW COP units on eBay 21-09-2004 Possible COP fitment (Beru) : ||beru nr||beru ref nr|| connection||length in mm||ohms || ||ZLE 232||(BMW) 0.300.122.102||M4||117||2000 || ||ZLE 233||(Audi/VW) 0.300.122.103||M4||122||5000 || ||ZLE 234||(Mercedes) 0.300.122.111||M4||113||2000 || ---- '''Fuel system''' A fuelpump pumps fuel from the tank through a filter to the fuel rail where your injectors are fitted and then through a fuel pressure regulator through the fuel return line back to the tank. The fuel pressure regulator regulates the pressure in the fuelrail so the injectors can inject fuel with enough pressure. Normally the pressure is between 2,5 and 3bar. * fuelinjector: A fuelinjector is a pretty simple but delicate and precise part. Its a housing with a relative big electrical charged magnet, a needle a common spring and holes to get fuel to the needle. The spring + the fuel pressure keeps the needle closed, the magnet moves the needle and opens the hole to inject fuel. This opening happens in micro seconds and the whole secuance of opening, hold open and closing just takes milliseconds (1/1000 sec). Opening your injector by connecting your injector direct to a battery wil destroy your injector. The coil inside gets to hot and burns your injector. Opening of the injector is called Ramp-up and closing Ramp-down, there is also the battery factor involved. When the battery voltage is lower, it takes longer for the injectors to open. This is compensated in the Battery_Factor value in Base Settings -> injector settings. Injection takes time, Ramp-up+opentime+ramp-down compensated for battery voltage. Fuel injectors : 3 pcs.DENSO 23250-87701-000 295cc/min Injector fuel pressure rating : 2,5bar (Manual) Fuel pump 80 litres/hour : 1330 cc/min Injector solenoid electrical resistance : 13.8 ohms Fuel injectors : 3 pcs.DENSO 195500-1350 460cc/min Injector solenoid electrical resistance : 12.6 ohms note:: I have a other set 195500-1350 wich measure 2,6 ohm the diffreance is in the color of the top but measure to know. You can ad a 10ohm resistance to run them in high ohm settings or change some parts on your board. ---- Flyback: i fitted the diodes and a wire from the trace to EC36-23 but i never thought about it to pull a wire from EC36-23 to the Injector V+. I read evry where you fried your board if its not connected but my board still seems to work well. Update: 15-01-2011 I think i figured out the injector problems. Version 3.2 already had the Fet drivers installed. I got confused building the unit with the LowZ and highZ setup, for highZ you should short SJ1 and solder D6 wich are not onboard of the 3.2 unit but on all previous versions. In prior versions you should also short pin 2->7 and 4 ->5 at the Fet drivers solder place. But mine where already there. So what i did i configured a LowZ setup with the diodes in highZ setup. Some how this protected my unit from destruction but also prevented the injectors firing like they should. I connected a 0,5w light bulp and switching them on takes a couple of seconds and off to. tomorrow i desolder the 20v HighZ deodes and replace them with LowZ m124 B14 diodes in the correct way and check voltage at pin 3 + 6 from the Fet drivers for 12volts. Update 27-1-2011 Yeah car started and run for a minute when the cam trigger tooth knocked of the hall sensor from its bracket Before i removed the loom and board from the car for repairing the WBO2 pump - wire i checked voltage on the FET driver. Voltage was 0 at the supply pin. Reading the Wiki for information i found for driving the Fet's it needs to be higher then 6v and 12v is normal. R154 on the back of the board on version 3.2 is the supply source of the drivers, and was missing. I also soldered D14 and D27 wich i removed again because they give ghost triggers, and R142 and C62 between pin 26 and 29 TPS supply and 5v wich i removed again because didnt see a point of pulling up voltage on the TPS wich works well on 5volts. Finnely building the board and loom back into the car and tested the WBO2 wich still gave faulty readings. Checking the pcb wiring from Pin 7 southbound the circuit to C50-C54 was damaged and giving the error.
