Got my microtech hooked up. Its a used one so the mapping is allready done (isnt sure it suits mine, but it is for an FC stock t2).
Ive traced all the wires many times so i dont think its that.
The problem is no spark at all! i checked that the tan wires got 12v ign and i also traced the gray/black and grey/red one more time. What can make the trailing coil not spark?
It did spark with the old ecu.

My ECU doesnt give any signal at ign output #3 and #4 (trailing coils).. Ive scoped it so im 100% sure that thats the problem. Is there a wway to turn the trailing ign on/off? someone got an ide what can cause this?

Done some more testing.. When i selftest the trailingcoil sparks! and i get REF and RPM errors.. Tried to disconnect the plug with the CAS signals, still get REF and RPM error but i dont get the HOME error... Dont understand how the microtech shuts off the trailing coil.. when cranking only the leading will fire!

I also have a RPM signal on my microtech, when i selftest the dash tacho shows 750rpm and the microtech shows 350rpm

 

i got soome pictures of an other microtehc.. on his handcontroller it shows CRANK in the output area, on mine it is 12.14aS and in the manual **.**mS .. what is correct and what is after-start enritchment active?

 

The After Start Enrichment function supplies additional fuel for a short period after starting the engine to assist with initial engine warm-up and to prevent leaning out as engine conditions normalise. This option allows you to set the amount of additional fuel to be supplied while this function is active. This value is expressed as a percentage of the total injector open time.

 

OUTPUT (bottom right):

Displays the injector open time (after all adjustments) in milliseconds, as well as displaying indicators and warnings as various features come into effect:

SYMBOLS:
mS = milliseconds injector open time
mL = ECU data logging active
Decel = deceleration fuel cut active
aS = after-start enrichment active
sT = staged injection active (i.e.: primary currently on)
Pump1M = Pump 1 triggered in MAP mode
Pump1T = Pump 1 triggered in TPS mode
Pump2M = Pump 2 triggered in MAP mode
Pump2T = Pump 2 triggered in TPS mode
WARNINGS:
Max Duty Cycle = injectors are open for the maximum possible time.

Water Temp = Temp over 100c
Revlim = rev limiter operating
Revcut = over-rev engine cut operating
Bstcut = over-boost engine cut operating
Battery = voltage too low or alternator charging too high
Shift = shift light activated (Dash only)
Boost = over-boost warning light activated (Dash only)

ANY HELP WITH THESE???

 

No doesnt help I still got REF and RPM errors and no spark at trailing..

 

Trailing dont sprak during cranking. I went through the same stuff.

Thanks, but my car still doesnt start and i have the RPM and REF problem!

 

What kind of coils are you using? Are you still using the base map or has it been played with?
Are you using stock coils or bosh coils?
Faulty or wrong type of coils will get you a rpm ref error.
