As my Genboard v3.3 seems to be installed (see MembersPage/JoelZernask), I will now try to dig through the configration.
I have prepared a configuration based on Ben Nesbitts configiration and I would like someone to take a look at the trigger configuration
- http://www.vems.hu/files/MembersPage/JoelZernask/config.txt
- reset_engphase_after=3F doesn't seem good at all. F0 (decimal 240) is recommended unless 240 is not a multiple of the crankwheel tooth (216 recommended for 36-1 wheel)
- the cam trigger
- starts at 77deg BTDC (phase= 40hex ??)
- ends at 47d BTDC (phase=43hex ??)
- The next crank trigger occur somewhere between phase=40hex and phase=43hex. -Jörgen
- what ??
Take notes of the _ALL_ input pulses with real world units (crankdegrees) first (don't forget to mention cylinder !!!) .
- not only cam-hall, but the primary wheel missing tooth as well
- without this we can only be sure that the above guess is wrong, but there is no sufficient info written to make good values
I have studied MembersPage/BenNesbitt, who also has a V8 Audi, but he has coil-on-plug ignition, so not entirely applicable to my project.
Here are the specs of my engine:
- 1989 Audi PT 3,6 liter 32valve V8
- trigger: Primary-VR (4 trigger pins on the flywheel), Secondary-HALL
- firing order: 1-5-4-8-6-3-7-2
- ignition type: wasted spark
- coils: two 2*2 coil packs (Bosch 0 221 503 407)
Ignition.
Cylinders firing together are:
1 5 4 8
6 3 7 2
The coil packs are connected as follows:
EC36-pin35 to Coil 1
EC36-pin33 to Coil 2
EC36-pin34 to Coil 3
EC36-pin36 to Coil 4
Therefore cylinders are wired as follows (see GenBoard/Manual/DigitalOut/Table for driver channel numbers):
Cylinders 1 & 6 to Coil 1 to EC36-pin35 drive00
Cylinders 5 & 3 to Coil 2 to EC36-pin33 drive01
Cylinders 4 & 7 to Coil 3 to EC36-pin34 drive02
Cylinders 8 & 2 to Coil 4 to EC36-pin36 drive03
- ignchmax=03 (03..00)
- IGNITION OUTPUTS TABLE: h[2]=03 02 01 00 03 02 01 00
- going from index config.ignchmax downto 0, the drive00, drive01, drive02 and drive03 will be fired, in this order.
This spark table can be used, right?
Be sure to get the base timing (trigger_tooth and igntdcdelay) right.
Fuel.
Again refeering to Ben Nesbitt's information, adjusted for my specs:
sequential fuel delivery for Audi 3,6 V8 PT engine
firing order: 1-5-4-8-6-3-7-2
Bosch injectors 173cc
Fuel map:
Below is the code I got by running Manmcd command on the brey terminal.

There is no spark. I think I have the basic trigger and ignition settings all wrong. Another thing may be that the VR sensor does not read the 4 pins on the flywheel correctly - when cranking, the rpm display jumps to 1800.
Constant for RPM calculation should be 1500 (8 cylinders), right?
Req fuel is 16,7 in my case (173cc injectors).
Here are Ben's trigger tables. How should I fill the first one on my 4 pins setup?
This one should apply to me as it is.
Is this h[0] table correct?
Communication problems
- by default (yours too, since you didn't require otherwise!) assembled v3.3 is shipped with RS232 on EC18pin14 and EC18pin15, see GenBoard/Manual/CommHardware (webshop text says same!)
After repositioning of the wires (getting it bad first?) we managed to get the only "Success!" message from the MegaTune.
- assembled and clamped v3.3 is preprogrammed. Used for testing (although the firmware could drive an engine, upgrade is recommended)
- 2. But there was still no communication between the ECU and my PC. I have downloaded and unzipped firmware 1.0.23 and MegaTune r028. Follow the instructions in the zip to upgrade firmware
3. We installed the Bray Terminal to see whether the ECU is alive. (exited from MegaTune for that time of course!). The <0>'s kept flowing and flowing endlessly.
- first, check your GND and GND5 connections !!! If you have a broken ground, or cigar-lighter groundloop to the notebook, that can result in similar
- 9600 baud: Man command
- No Hello! sign came out after Man command, just the <0>'s kept running.
- 9600 baud, but view in hex: 'A' command
- result ?
- BootLoader test: 19200 : 'S', 'p', 'v' commands
- result ? If "AVREFI1", "S", 30 or alike, you are on the track, in bootloader, just exit TerminalProgram and upload firmware without "t" option to prog.pl or megaloader (using Ew instead of Etw flags)
I suspect you maybe have started a firmware upgrade that disconnected in the middle or something. Don't worry, in the worst case powerup the ECM with the ECM's RS232 (pin2 and pin3) loopbacked, than remove the loopback and plug in the PC. Bootloader test should work now, and you can proceed from there.
Hopefully the bad connection didn't damage the max232 or something. If you disassemble the ECM, don't clamp it back until:
- remove D100 if you use powerflyback and PWM-ing 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)
This problem is solved - it was all caused by a wrong ECU-PC connection.
