Summary of change:
Hallo I am from Denmark and I am planing to use a V3.2 on my VW Golf GTI 8V. MembersPage/HansK/IgnitionSetup MembersPage/HansK/EgoReadingProblems MembersPage/HansK/History ------------- 2005.07.16 Q.1) Does the MAPdot work fin, and should it be a certain firmware/megatune I use? Q.2)When i open my Lambda Table in MegaTune (r18 and Firmware 1.0.12) the numbers are all wrong.. http://www.vems.hu/files/HansK/Lambda_Table.jpg I can get the same numbers out of the board again with the Terminal-program as I put in.. But they don't show in MegaTune? The lambda-tuning works good with recommended latest released firmware (GenBoard/UnderDevelopment/FirmwareChanges currently v14_rc1) and latest MegaTune (verify with mct that MegaTune vemsv3.ini is acting properly). '''Yes''' It works again with the new firmware and MegaTune r23. Q.3) If I download the new Firmware 1.0.14 to the board, I want to to do some new testing on the table but now I mounted all the transistors in the box.. Should I just put a lightbulb on all the outputs or what to do? yes. Actually final testing is done after mounting the TO-220 FETs and IGBTs and clamping them to the Alubos (the IGBT-s can short to neighbor or case if not done right). Likely you have a few econoseal recepticles that you can hook up. * OK, but don't there have to be something connected to FETs and IGBT outputs? ** the FETs and IGBTs are not at risk when nothing is connected to the output. In fact most setups run with typically 2 IGBT-s connected (4cyl wasted spark), while often 8 IGBT-s are installed in an assembled ECM. However, testing with some load is nice, because it provides more information: someone reported that after he killed a FET with short-circuit output to 12V (without a sufficient fuse) the FET still switched a few microAmperes and looked OK with the DVM as only load: they had no power to switch on even a small 0.5A lightbulb load though. ** poweroff test: with DVM measure ohm (or diode-mode) between EC recepticles of neighboring IGBTs (or between any 2 IGBT outputs if you are lazy to look for neighbors: this is 8x7/2 = 28 measurements, takes 2 minutes with DVM, especially fast with beep mode) to see that none shorts ** We apply LEDs and series resistors between output and 12V supply (or 5V supply OK too, eg. EC36pin28 or EC36pin29 suitable as well). Than apply mdh commands (see GenBoard/Manual/DigitalOut/Table) to see that outputs switch on/off as needed. Take care that ..._channel=FF in config during this session, otherwise the output will be what the firmware thinks appropriate for that channel. ---- Please post your config.txt so that others can review and hopefullly learn (especially me ;) Thank you. http://www.vems.hu/files/HansK/Config.txt It is not in use yet so don't put too much in it, but you are welcom to give input. ------------- 2005.06.19 Q.1) I have a 2-pin idle-valve, but what settings should be used fore this.. PWM, ON/OFF? Any solenoid works with ON/OFF. Only some work (well) with PWM. ** what is resistance ? ** anything known about original application? Does it have real idle-air control or just simple "fast-idle" ? Does some one use the the same valve, and have a config-file that I can see or just some input to what settings to use? http://www.vems.hu/files/HansK/P6220090.JPG Q.2) Is there some way to test the idle-output? ** which output did you choose in iac_sol_channel ? ** PWM type iac output can be tested with forced iac.position: mdi01..mdiff . Do NOT forget to set back to mdi00 (or reboot) after you executed the tests to revert to normal control. ** alternatively it can be tested like any other digital output, with mdh.. command. See GenBoard/Manual/DigitalOut/Table. In this case, do NOT forget to set iac_sol_channel=FF to prevent interference and set it back after the test. 2005.06.01 I got the new Megatune "mt-r014" and I tryed to use the firmware that was together whit it, but then I got no "output" on inj. or ign. and the the config and table was the same..? '''No problem..''' Just needed to chance secondary_trigger to "02" instead of "FF".
