Ignition problem on Audi 2,2VT AAN engine

[jyrarrak]

Hello,

I have problem on vems 3.3 (conf 1.1.88). It has EC36 and EC18 pinouts. First of all it was ordered with 8 ignition driver. To use aan oem ignition system I removed 5 igniton driver from the board and bridged 2 driver legs. Car starts and works well in idle and normal driving but at boost car accelerates weakly. Feels like the boost blows spark away. All 5 ignition signals took from ec36 logical outputs:
1cyl - ec36/10
2cyl - ec36/12
3cyl - ec36/11
4cyl - ec36/24
5cyl - ec36/35
If I use motronic or friends vems 3.3 with motr55 pinout car works well. In plug'n play vems 4 ignition output is took from stepper output and 3cyl is from ignch4. In my case 1,2,4,5 cyl from ec18 and 3cyl from ec36. Does this is the issue? In ec36 pinout is +5V and in ec18 +12V?

Usual way for Audi logical outputs is to lower in line resistance from driver. Originally there is 510 Ohm for each channel. Commonly is to solder another 510 Ohm in parallel - resulting 255 Ohm.

Solder drivers back to board + resistor 510 ohm to each driver?

No no no. Just add 5x 510 Ohm.
