hello has anyone got a diagram or point me in the right direction to convert a ecu from hall to vr triggers thanks

primary trigger?
-
both if possible but primary would do

its board v3.8b

and you need to find there r30 resistor is :)
-
ok looks simple enough so do I have to replace an existing resistor with a r30 one or add one to the board thanks for your help

remove existing and replace it with something from 18 to 27k google vems schematics, you will find where it's located
-
ok thanks a lot
-
located it on the schematics does this look like the corect replacement resistor

looks like right one
-
right ive replaced the resistor and left sj2 unsoldered and soldered sj6 only problem is getting no rev counter and no trigger is there anyway o test if the ecu is reeding the trigger ive scoped the crank sensor and working fine

does ecu have lm1815 chip installed?
-
if its just above and to the right sj6 then no i dont think so

yep, you should have one there ;)
-
ok I'll sort it thanks
-
been able to spend a few hour on it today fitted the lm1815 chip to u11 and still not seeing a crank trigger do i also need to fit one to u12 or is that for trigger 2 only

pics of the board please :)

have you an email address I can send pics to it's hard to get them off my phone since photobucket changed
