The car is an old Ford Fiesta with 650 kg starting weight, the motor is a 2.2 liters Ford Probe 4 cylinder turbo engine.
There was some confusing information about
- next trigger tooth another_trigger_tooth=14 in the vemscfg... This (20 decimal) is terribly wrong for a 4 cyl, should be 30 (as in the 4cyl 60-2 configlet in primary trigger dialog)
- it was 30 all the time I was just trying the 6 cylinder setup
The modifications in the engine ara 4 H conecting rods and custom pistons, the motor is now 4 cylinder an 2,4 liters, for the first run we are keeping the stock turbo an later we will upgrade.
I have made the wiring harness but first the car wouldn't start because of no primary trigger signals. (RPM = 0). It turned out ECU was ordered with HALL input. After changing to correct VR hw setup, the engine started to work (see below).
Wiring - Outputs

Wiring - Inputs
- ec36 pin 23 flyback

- ec36 pin 14 coolant
- ec36 pin 26 sensor ground
- ec36 pin 27 primery trigger
- ec36 pin 29 tps supply
Trigger details is it 60-2 ???
Yes it is!!!
For VR always use rising edge setting (not falling).
I tried both put it's almost working with rising
- sensor resistance=502 ohm
- DC volate = 360 mV (measured with ignition on)
- optional: AC measurement
I will make an osciloscope of my soundcard => GOOD !
- a triggerlog would be reasonable
- (use 1.1.81 or newer firmware to capture triggerlog)
First is recognized it's a HALL sensor jumpering in the ECU (as the ECU was ordered) then I solved this problem by soldering the jumpers (... how exactly...?). But the missing trigger signal wasn't solved jet.
SJ2 opened SJ6 closed. (This is OK from primary trigger VR)
We have changed the primary trigger wheel to another 60-2 tooth wheel but from a factory opel engine, now we have 230 rpm at cranking we will try to start the engine soon
We finally started the engine. First time we had trigger errors but some adjustments in the trigger settings and the engine started to work. The gearbox is isn't finished jet so we couldn't go to a test ride.

The engine wouldn't start now the spark is not there were I am adjusting the setting and it's same in the 1 st and 4 th cylinder but it's different from the 2 nd and 3 rd cylinder. And I had some issue with the vemstune I burned some settings and it wouldn't changed but if reread with a restart it was correct but in the 4 th reread it was a false value.
We don't have stable tigger signs I think because of the missing tooth but I can't figure out how to change of this. The sign after the missing tooth is not clear (see the picture) I think the vems can't find the correct missing tooth. I rewired the VR sensor with shielded cable I have trigger signs always but the ignition timing is still not correct. I checked all the settings and I will upload the knew setting. I also tried the new 1.1.82 but the same problem is on. I wanted to make trigger log but my vems tune didn't record anything (I tried before and it worked)
The car original ignition was a 24+1 trible vr sensor but to use this I have to change the jumper settings in the vems but I have't find exact descripton of this it only says:
* for secondary trigger=VR (when not using the 3-sensor auditrigger), we recommend that EC36/13 is used as sectrig VR input. This way EC18/12 can be used for analog input (0-5V, sensitive mcp3208 input).
o The second LM1815 and the related blob at the bottom side under the FETs is needed.
* wether you order assembled or assemble yourself, read the recommended econoseal pins at [webshop page]
But if I have hall setup for secondary trigger and I want a normal VR setup what are the steps, and where is the related blob exactly can you give me a correct discription step by step what is needed to change the secondary trigger from HALL to VR???
I would return thanks for any help with this.
