Details:

1993 Audi 80/90 Quattro

1997 Audi A8 4.2 liter V8 engine with sequential injection and coil-on-plug ignition.

Using a 60-2 trigger wheel on the crank with a (I think) VR sensor from the 1993 12v V6 and the stock A8 4.2 cam position sensor (Hall).

USE THIS INFO AT YOUR OWN RISK, I AM NOT SMART

Being that my own project was about to join yours in the Pacific, I loaded your config into my board so I could read it, here is what I think, KEEP IN MIND, MINE IS WORKING, JUST DIES FOR A SPLIT SECOND

BASIC SETTINGS

CONSTANTS

PRIMARY TRIGGER

FUEL PUMP


14oct PROGRESS!!

Right, so I disabled afterstart enrichment and discovered that the motor is just not getting enough fuel. Does it get enough air? what is MAP reading?

It was slobbering rich with lots of smoke at first start and then after a little while (255 cycles, I imagine) it would purr like a cat for a few seconds then start surging and die. After disabling afterstart enrichment, it starts and barely runs with NO SMOKE and I cannot keep it going.

Firmware .18 dual fire

mtr024

here is the recent output from the VEMS. I am stumped so any input would be good.\n

28 September 2005//

Ok, I got my wiring hooked up and the board says Hello

Here are the steps I have just taken with the new software. I will now head over to the car and see what happens:

1) Erased everything on the hardrive having to do with mt/vems (Vems ECU still has .18 firmware on it).

2) downloaded firmware .18, firmware .18 ignition dual output files, mtr024, mtr025 ini.

3) unzipped mtr024 and mtr025 ini. Replaced the r024 .ini with r025 .ini in MegaTune2.25b602/mtcfg folder

4) unzipped firmware .18 and .18 dual ignition output files, inserted dual ignition files into firmware .18 directory

5) deleted the .15 firmware native to the the megatune folder and replaced with the new .18 firmware folder.

6) deleted the pre-existing config.mtt and tables.mtt files in the firmware/ect folder

7) converted the existing config.txt and tables.txt to .mtt files with:

perl bin\make_table.pl tables.txt tables.mtt

perl bin\make_conf.pl global.h config.txt config.mtt

And put them in the firmware/etc folder

8) now I am ready to burn the firmware to the VEMS ECU again, right? I don't see why it would be needed, if you already have the newest (1.0.18 at this time). You can verify first. (but burning again is not a big deal either)

IT WORKS!!!


IGN_DUALOUT

(ben writes) This info below is a little fuzzy to me. Is this a hack so I can run without the second trigger wheel for a while?

I guess we might as well make it go with wasted spark if possible since it sounds like I need to make a new trigger wheel for the cam.

(/ben)

On Jorgen's request, Marcell compiled a firmware with IGN_DUALOUT: http://www.vems.hu/files/Firmware/release/v3_firmware_1.0.18_IGN_DUALOUT.zip

I added the note to GenBoard/UnderDevelopment/FirmwareChanges that MegaTune vemsv3.ini needs a small change. With the old definition of "42 bytes of runtime-vars", MegaTune will beep like hell.

It is untested (but compiled with the same compiler as other releases, that all passed testing).

IGN_DUALOUT means, that

So a sane configuration is:

With a 60-2 wheel, and another_trigger_tooth=0x0F (decimal 15) only the first four element of h[2] is actually used (but with IGN_DUALOUT, each fires 2 channels). Eg. if you configure trigger_tooth=03,

are fired. The exact time is (ign_tdcdelay/2 - actual_ignadv) crankdegrees after the tooth. ( ign_tdcdelay is 0.5 degree resolution, but MegaTune does the conversion for you IIRC)
