Visit Preferences to set your user name Summary of change: ---- '''Page Listing''' * MembersPage/DuncanThomson/Config * MembersPage/DuncanThomson/Table ---- '''Project Description''' Looking to install a v3.2 Genboard onto a naturally aspirated Audi inline 5 cylinder engine (KV). * Genboard v3.2 * 4x20 LCD * sequential fuel injection (5 cyls) * ignition via distributor (initially, progess to direct later) * WBO2 * EGT * MAP sensor on Genboard * 60-2 crank sensor * existing cam sensor in distributor ---- '''Questions''' ''WB02 calibration'' Following the procedure for calibration, and the voltage checks for the pins are giving me trouble. Docs specify 3.96v from GND to Pump -ve, and 4.41 from GND to Nernst, with 450mv from -ve to nernst. I have a steady 4.02v on pump -ve, and 4.38v on nernst. What are the satisfactory limits here? Also, I am using cheap 100ohm resistors at the mo' reading around 98ohms each, what effect would this have? ''Crank sensor'' I'm looking at using a VR sensor to pick up on a 60-2 toothed wheel which will be attached to the crank pulley. * From what I can gather, it's best to count the gaps, which leads to a wheel with a 3 degree tooth followed by a 3 degree gap, all the way around the wheel. Then the -2 is achieved by not machining two of these gaps. Is this correct? It would be nice if you could check a few times during machining the missing tooth (before full depth is reached) with a notebook soundcard (and some temporary mount for the VR sensor). If this is not possible, examining a factory 60-2 to get a feeling of it should be the minimum. If you have a space EC36 pin, it might be a good investment to have a separate pin for VR- that is connected to GND near the LM1815 chip (not through the EC36-pin26 GND). The idea is to keep signal seen by LM1815 very clean for best lowRPM (<200 RPM , small signal) behaviour. Although EC36pin26 GND is not as noisy (by far) as the GND5 decreasing it further might be a good investment if the free EC.. pin is available and ECM unassembled. EC.. is perfect, just sharing current paths might (which is common for GND) inject some noise (that is usually below problematic limits). At this stage it looks like I'll need a number of extra connections through the endplate, so far: * MAP pneumatic tube * VR sensor * PS2 keyboard * LCD Looks like it may be necessary to mount a number of these on the rear endplate with long cables so I can remove the board from the case if necessary. ---- '''Answered Questions''' ''MAP Sensor'' * in manual the sensor is mounted on the BOTTOM side of the board * but I have since seen another image which shows the sensor mounted on the TOP side of the board I recommend mounting MAP on the top of the board. Better for getting the tube through the frontplate. Note that MPX4250AP pins must be bent to the other direction depending on the top/bottom (so that notched pin is close to AVR in any case) ---- '''Progress''' * '''29 May 2005''' Connected PS2 keyboard. Can now change screens etc without use of a laptop. * '''23 May 2005''' Have an LCD attached, got the LCD going, and added an inline fuse to the power supply. * '''18 May 2005''' Got my "Hello>" back from the board as well as the test screen. My variable power supply only allows current limiting at 35mA or 1.2A, so will have to get a fuse before powering it up again. * '''16 May 2005''' Recently received my v3.2. Currently in the process of soldering on the components required to get power onto the board. Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
