I would like to install a Genboard v3.3 to the following car:
Audi S2 coupe quattro 2.2 5 cyl 20v 3B
This 5cyl needs InputTrigger/AudiTrigger see "Configuration" info, your config does not comply !
- see GenBoard/UnderDevelopment/FirmwareChanges
- firmware 1.0.29 used
- MegaTune r028 (r027 should work too).
TODO needed for debug
- TerminalProgram
- disconnect megatune
- brayterm 9600,8n1 connect (COM1 or whatever)
- Man
- mll - sends LCD content, just to test if we are in "Man" menu
- start log
- mcd - so log contains config
- mct - so log contains tables
- mdd0c
- cranking (4..5 sec)
- stop log
- upload log to internet
- bye (this changes mode to MegaTune binary protocol; a reboot does the same)
- disconnect from Brayterm
- connect MegaTune
- (Man, mcd, mct, mdd0c, mdd04, mdd00), start log/ stop log / send file (mtt file)
- DONE: publish mcd, mct dump
- TODO: describe all trigger connections, including shield and pullup
- photo of cable
- check against InputTrigger/AudiTrigger and InputTrigger/AudiTrigger/TestLM
While the trigger is special, the other sensors should be no problem at all.
My V3.3 include:
- Primary trigger VR
- secondary_trigger: auditrigger
- MAP connection: 400kPa onboard
- LCD an PS2
- 2 Knock and EGT
- ignition driver: 6+2
The car use the absolutely factory sensors and accessory but the air filter's house was removed.
I want to make a street racing car from above.
Project to follow:
- samco turbo hoses
- tubular turbo exhaust manifold
- bigger turbo than original
- erl water injection
- engine internal modification /pistons,conrods/
My plans:
- use a factory 55 pins Motronic male connector to EC18 and EC36 and make a flying cable set + WBO2,egt custom made wirings to engine.
- Anti lag system
- Launch control
- Boost control solenoid
- Distributor based ignition
- Sequential injection for 5 cyl '14.5 ohm'
- 2 knock sensors, but I think use 1 knock sensor.
- Primary trigger VR 135 tooth crankwheel (no missing tooth)
- Secondary tr. HALL trig 1 window/720° camtooth. Overlaps VR.
- Secondary tr. VR trig 1/360° cranktooth
- factory CLT
- factory IAT
- factory TPS
- 1xWBO2
- 1xEGT
- LCD
Please check my planned pinout and correct it if necessary.
EC36
1 TPS sign.
2-IAT 450-650 ohm/in 20°C
3- fast-idle small solenoid or relay (or any low-current output, such as shiftlight). EC36pin3 is a 350mA output, see GenBoard/Manual/DigitalOut/Table. You might want to use the powerful injector outputs first (don't forget to adjust h[0]=.. entries) and use the low-current outputs if you run out of injector outputs. Care is needed to not overload outputs.

For traditional dumb coil, you want to use one of the 6 power (non-logiclevel) ignition outputs. h[2]=.. (ignition sequence) must be adjusted for the chosen output in any case.

DO NOT forget to read the warning of the provided resckue-kit paper, about GND5, flyback, and fuses.
Please link to the docs you're trying to use. See MegaTune page for (simple unzip) install.
The v3.3 has max232, so a standard RS232 port is needed. See GenBoard/Manual/CommHardware
If unsure about MegaTune setup / compatibility, in 9600,8n1 say \n
Man mll mcd mct bye
without spaces. mll prints LCD content of active page (even if no LCD connected), mcd and mct prints config and tables. bye (note: everything is case sensitive) goes back to MegaTune compatible mode. Since MegaTune is much simpler to use, you don't need to learn GenBoard/MenuSystem, but if you like:
But 1.0.19 will NOT work with the InputTrigger/AudiTrigger , since it is a new development.

Trigger signal debugging
The from genboard I can see the following signals:
- 135 cranktoots on 0.8V DC with 1.9V AC-peak to peak about 400Hz,40mV noise on cranking
- 1 teet crankhome VR on 0.8V DC with 2V AC-peak to peak about 40mv noise on cranking
- hall 1camsign startpoint 4.7V neg pulse about 10msec on cranking
The signals look suitable. The problem was boiled p259 chip, likely operated with missing GND or GND5.
Testing on the bench
- the board was sent to Budapest to be tested on the bench
- modifications done:
- C103 was replaced (to 1nF)
- R182 was shorted
- 43k pullup to 5V was installed on crankhome-VR input. Should be enough without external pullup.
- ALS activation switch input (SDA) was connected to EC18pin16. Note that only AVR internal pullup is enabled, an external 4k7 resistor connected in place of the ALS switch pulled down 4.8V down to 0.57V). Beware that this is unprotected input. Anything above 5V or under 0V will kill the AVR.
- we found that p259 was fried. Very likely that GND or GND5 was not
- this prevented trigger detection (broken p259 pulled down internal supply that powered the LM1815) and the p259 outputs (fuel-pump relay was controlled from this
- p259 was removed, than (after some testing, and found other functions to be OK,) a new chip was installed
- tested with c270_670.wav fed into EC36pin27 (primary) and EC18pin12 (secondary channel. It works nice.
- HALL input (EC36pin12) was tested this way: first left open, than pulled continuoisly to GND (in normal operation, pulled to GND once every 2nd crankrot, hard to test with 2 channel soundcard, but this simpler test also tests the input perfectly). Found an interesting thing: when I ground HALL continuously, firing (ign/inj) stops as it should, but RPM keeps updating, which is confusing. Well, this was 1.0.29 firmware 1.0.30.
- 1.0.29 didn't increase wheel-error for secondary trigger problem (like 1.0.30 does). mdd0c auditrigger log works well though.
- upgraded to 1.0.30 compiled with ALS (global.h is the same, but air and clt temp patched to guessed curves: vems_airXfactor_2400_287_cltfactor_2400_287.hex)
Suggestions:
- move fuel-pump control to a free injector output (other input of the relay is connected to injector-common +12V )
- proposed: EC36pin17 (see GenBoard/Manual/DigitalOut/Table):
- last element of h[0] becomes 80 (decimal 128): h[0]=08 02 01 04 10 00 00 80
- after setting h[0] last element, test with mdhf0 and mdh70
- after testing the above way, set fuelpump_channel=70
