Trigger data (firmware 1.0.69)
---- Primary triggering: |
|
60-2 no camsync, 4 cylinder using firmware 1.1.12
* batch injection * wasted spark ignition * stock Peugeot (Magneti Marelli?) VR sensor (3 wire)
|
| Currently using the stock Peugeot (Magneti Marelli) triggering. It uses a 60-2 flywheel with VR sensor. The first tooth after the missing tooth is at 120 degrees before TDC of cylinder 1. |
|
Trigger timing is as shown in the picture. Running direction is Counter Clockwise (wrt picture), 1st and 4th cylinder are at TDC. BTDC = 120 degrees.

Secondary trigger:
Currently the engine does not have a secondary trigger. I will therefor run batch injection and wasted spark. After I know the ins and outs of this setup i will use a secondary trigger for sequential injection and coil on plug for better control. |

Previous problems to learn from:
I had issues with the triggering of the engine. The engine didn't run properly when set up for 120 degrees (trigger_tooth=0A and ign_tdcdelay=0x78; 10*6 + 120*0.5 = 120 degrees)). Remarkely it did run when setup for 60 degrees. |
| I think a VR sensor is easiest to apply. More about that later. |
| Although it is not clear what exactly caused the timing problem, after using [ALSfix] my problem was over and the engine started with the correct timing. |
