high all happy to see a vw megasquirt forum
my name is Mbaye from senegal west africa i'm runing vw abf engine 60-2 whell wasted spark 4 bmw coils 2 modules 0227 100 200 from peugeot in my actual internal wiring xg1 and xg2 are jumpered tachselect to optoin ; optoout to tsel
pullup 1k to 5 V proto area r26 to ign spark A r29 to spr4 spark B
is my wiring correct cause i see in a post the xg1-xg2 jump is cut
thanks

Based on what you are describing you are set up for a hall type rpm input. You need to set things up for VR input. http://www.megamanual.com/index.html go to step 50 for instructions.

the crank sensor got 3 wires i think for vr sensor you have only 2 wires
actualy the engine start and idle well can you please explain how can i do
thanks

Actually most VW crank sensors have 3 wires: Sensor +, sensor-, and shield (goes to engine ground) I'm not sure about the ABF but I know that the ABA, AEG, AWW,AWP et all use a 3 wire VR sensor pinned as I described.

yes i know for the ABA but on the ABF sensor 3 pins there is no shield it's black + brown groud and white /blue midle wire is the signal going to ms but anyway can you confirm me about xg1 and xg2 jump or cut i can show you a picture of the sensor if you want
thanks
Mbaye

If your sensor is in fact a hall type then you will want to keep xg1 and xg2 jumpered. Is there power going to the sensor on any of the pins?

yes there is a power 12 volt on the sensor the engine is european vw golf 3 2l 16 v 150 hp year 93

You shouild be good to go then
