Summary of change:
= Project Page Home = My name is Anton, I'm 18, live in Helsingborg Sweden and I'm building a '94 Audi 80 Quattro. It originally has a 2.3L 10v N/A engine in it but I'm building a turbo converted 2.3L 20v to put in it and a GenBoard v3.3 to run fuel injection, boost control and distributorless ignition. I'm doing this partly as a school project, by myself. My biggest "role model" for this project is Javad Shadzi and his car, http://www.80tq.com/20vtMotor.html See InternetHorsePower ---- '''Hooked up serial, keyboard and LCD.''' * '''serial number 303''', sent out on 2005-07-09 (among the first 5 v3.3 - these had no R181 PNP-ed) ** apparently you assembled yourself: '''confirm R181 has been soldered''' (100 .. 180k) according to the note you received from the shop: If using VR on primary trigger, please check R181 100k (0805 size SMD)resistor at LM1815 pin7. (min 47k, max 180k; 100k recommended: you can find 100k in rescue kit marked as 104 ). *** R181 is connected to '''LM1815pin7''', so NOT the two pads right next to LM1815 pins 6 & 7 (which is the 3 pin header connected to LM1815 pin5, leave that 3 pins open!) *** You do not actually need the R181 resistor when using HALL as primary, but recommended to install it anyway to avoid future surprise (if using VR later). Anyway, have a note about this in the logs (or trigger related notes) that you write for your ECM. *** believe it or not, I independently copied the old R181 note (we even had an edit conflict when I saw your question and added more info on the pin). ** remove D100 if you use powerflyback GenBoard/Manual/PowerFlyback/RemoveD ** change C103 to 1nF if using secondary trigger HALL : Manual/InputTriggerHardWare/ReplaceC ** set AREF=256 BuildProcedures/SectionThree (not required but recommended) The above is not related to MegaTune (version/comm) problem. == Questions == '''Q''': I'm following MembersPage/PhatBob/UserGuide and I've connected and powered up the board to the computer. * the keyboard/lcd works * I can work the menus in terminal, say "Man" in TerminalProgram or in the mini-terminal in MegaTune, but when I try to test the connection through Communication Settings it says "No Response!". The settings are as in the userguide. '''before trying megaTune''' * right after reboot (after powerup, default is binary megatune communication mode) ** tried: no success * if you can use the menu commands, it's in "Man" mode in which you will NOT be able to connect for normal MegaTune logging / tuning. Try "bye" (again), maybe you need to close the terminal window, etc...did you say "bye" in TerminalProgram (or terminal window) and received "Bye" from the ECM ? ** tried. But: was the "Bye" answer visible ? * MegaTune, firmware version ? ** VemsMT1.0.30rc3.zip ** firmware version is 1.0.13 *** mdv : "2005. júl. 5., kedd, 21.13.00 CEST" *** mdV: "1.0.13" Solution: '''These are incompatible'''. Either * find an old MegaTune release matching your firmware (unsupported. the shipped firmware is ment for testing ) * or upgrade firmware. The firmware bundled with the MegaTune is often a good bet (but read GenBoard/UnderDevelopment/FirmwareChanges anyway). * Try another serial cable? ** Does NOT seem to be a problem in your case * Another computer? ** this can work, if the other computer has a MegaTune installed that is compatible with your firmware ;-) * MegaTune install location: ** nope, MegaTune is not picky on the install location. This allows you to have several versions installed (eg. always have one -operational- for each install, eg. your customer's cars too) ---- '''Outputs''' The FET and IGBT places on the board can be assigned with much freedom. See GenBoard/Manual/DigitalOut, GenBoard/Manual/DigitalOut/Table * injectors => injector outputs * ignition => ignition outputs (logiclevel for active coils; IGBT based power outputs for passive coils) * bipolar stepper (if used) => stepper outputs * other outputs => after assigning the above use the remaining outputs. take care about current rating and flyback protection (eg. WBO2 second channel FET and DPAK "extraFET"-s have no flyback installed by default!) ** Use the higher current stuff first for more safety ** except for (low current like) LEDs (like shiftlight), where p259 outputs are the best ** don't forget flyback and GND and GND5 connections
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.
