As my Genboard v3.3 seems to be installed (see MembersPage/JoelZernask), I will now try to dig through the configration.
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 Ben's Manmcd code that I have modified for wasted spark ignition and 4 trigger pins + cam sync trigger setup instead of a 60-2 trigger wheel.\n

Channels 6 and 7 are unused, so I could connect the tach trough the VEMS. tach_divider=FF If I connected this tach through the v3.3, should I use the value "02" here? 02 seems right for the 4 cyl tach (but this config element will soon change to allow fine-tuning or deviant setup like 6cyl tach gauge on 5 cyl engine)
For VAG sensors, no firmware upgrade needed.
If I replace the code in MegaTune r028 config.txt with this code above, how can I send this code to the ECU? Will these new values appear in the graphic tables of MegaTune and simply "Send to ECU" command works?
