Serial nr 6858.
Multiple high current damage, Caused by burnt coil - damage mainboard
No comm. Mainbord replacement.
VR/Hall 2+6Logic. "2JZ VAG coils, Custom harness"

...

Unit nr 3:
Serial nr 9332
M50 PnP unit, worked for 1 hour, then just died. Some form of bootloader/firmware issue on reboot.
I want full refund on this one.
Will send it WITH external MAP sensor.
...
Unit nr 4:
Serial nr 13031
M60 PnP unit.
Never worked right, 2 cylinders missfires. Some form of manufacture defekt that manifests in problem with injector output or IGN output.
I am almost sertain the problem is with the injector outputs.
All outputs work when in testmode, all fires individually. But when enginge is started 2 cylinder do not run correct. Dead on idle. then runs in on mid load, then dead again on full load.
I made a "Patch harness" for this car, and used a stock VEMS 3.8 unit and it has run perfectly after that.
Even installed this defektive unit again, and the problem returned.
I want full refund for this unit, and 200 euro for the time spent looking for this problem. Spent 10 hours looking for a mechanical fault :(
Will send it in with external Map sensor.
...
I will send the first 4 units in one package because of limited insurance.
...
Unit 5:
Serial nr 13039
M60 PnP unit. This never worked. No trigger.
This has Manufacture defekt. This is not wired correctly. I have messured it and GND pins and Trigger pins are not where they are supposed to.
I want full refund on this unit. Plus 100Euro in handling of this problem and shipping fees etc.
Will send if in with External map sensor.
...
Unit nr 6
Serial nr 11151
Damage/faulty 5volt output and possible IGN fet damage and Stepper chip.

OLD:
Send detailed individual cost of each repair to Info at engdahlmotorsport.se
Ask for return address before sending back, I will change adress 2016-08-30.
Please send out the units 2-3 at a time. As soon as they are ready.
RS232 serial communications
Please note that devices with dual WBO2 (and old devices) have NFET on EC18/pin17 (2nd WBO2 heater), not GND as most new devices.
- That means RS232 connection with GND only on EC18/17 (RS232 GND not connected to EC36/26) will fail to communicate, or worse: sometimes communicate, but unreliably. (eg. communicate with engine off, but frequent comm disconnects with engine running).
