Visit Preferences to set your user name Summary of change: Hi I am starting building the VEMS board for my Corrado g60 turbo. Corrado 1989 1800 ccm Turbo Garret T3 60 trim Mail: motor at webspeed.dk http://www.vems.hu/wiki/index.php?page=MembersPage%2FPeterJensen%2FQuestions http://www.vems.hu/files/PeterJensen/config/config.txt http://www.vems.hu/files/PeterJensen/tables.txt/tables.txt http://www.vems.hu/files/PeterJensen/imag/cor.jpg http://www.vems.hu/wiki/index.php?page=MembersPage%2FPeterJensentrigger *Q. Coolant temp questions? Is ET possible to changes the limit of temperatures from 110 degrees to about 140 degrees. My Corrado is running 120 Engine Coolant Temperature max load so ET is out of limit It seems this will be needed sooner than later (the traditional megasquirt definition still in use is very bad, -50..+205C would be more appropriate to fit aircooled), it involves several things: * example for matfactor and airdenfactor inc files. Recompile firmware with changed tables of your choice, and you have extended range immediately. To get good reading in megatune, you also need: * redefine engine.coolant with extended range ** documentation issue ** LCD display ** MegaTune *Q. Haw to connect the knock sensor ? Direct on the board TopLeft 3-holes centre is -. http://www.vems.hu/files/PeterJensen/wiring/36-1_diagram_vems.jpg http://www.vems.hu/files/PeterJensen/wiring/36-1_diagram_vems.cdr *Make your wiring with Corel Draw just download the “cdr” file all images are already made ---- '''Need help for Wbo2''' When I issued the command “Manmde02”, the heater turned ON but it seemed to turn OFF again after one scan. The problem was: 1A supply was too weak If the supply is too weak: * GenBoard might reset. The uptime seconds counter (that is seen eg. in MegaTune) resetting to 0 shows this * or possibly, if the sensor is not heated in a reasonable amount of time, the heating decays to wbo2_fallback for wbo2_retry_t time when the heater PID controls takes another chance. La:??.? should be displayed when the heater does not reach target. If you want to tweak the settings, check the following config variables: (copied from global.h, the firsthand source of variables) <code> uint8_t wbo2_limit_maxt; // wbo2, max time spent at abs_limit [262msec] uint8_t wbo2_fallback; // wbo2, fallback V after maxt [1c=10V ff=30V] ... actually this comment is bogus, FF is 100% uint8_t wbo2_retry_t; // wbo2, retry control after [4sec] </code> ---- '''Need help for compiling firmware''' The released binary from GenBoard/UnderDevelopment/FirmwareChanges has WBO2 enabled. (in my_make MY_CONF += -D WBO2) I triad to compile like: 1. Make clean 2. sh 3. make all But no vems.hex fil will be generated http://www.au2stereo.dk/compiler.jpg http://www.au2stereo.dk/compiler1.jpg If you insist on compiling: * provide link to zip of some of your files, eg. ** my_make ** winavr version ** output of avr-gcc -v ** error messages: preferrably not images, but text files using output redirection or copy-paste (click on upper-left corner, edit menu) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
