36-1 ECCS / Trigger

Grant Baker

Recommended Posts


I've got a car here that is causing me no end of grief... It's a complete mess of a Ford Escort, converted to Zetec Turbo. 4Cyl, wasted spark, 1 injector per cyl, batch fired.

Couple of Link problems: (Atom G4+)

1) 36-1 Multitooth/missing set up. No cam trigger. Trigger 1 set to 36/1. Trigger 2 set to "sync - none". When you turn it over on the key the trigger errors go up by 1 every engine cycle and the RPM signal goes at 180rpm, but occasionally jumps to 400rpm for a split second. In Runtime Values, the Trigger one is immediately showing as ON as soon as the engine turns, but the ECCS Sync is always no. Is this correct?

2) Water and air temp sensors are the same, from a Ford, and don't show the correct numbers on any of the pre-defined tables it seems. At 14degC the resistance is 44.3kOhms and at 100degC it's 3kOhms. This is outside the range of the user cal tables.


Any pointers to help out with either?

Many thanks in advance.

Hi Grant,

Is the crank sensor reluctor? If so, check the polarity. Also, use a scope to set the arming threshold table voltages correctly. Using the scope should help identify if the signal is nice and clean, and if there is any noise creating an issue.

Which cal table are you using? Which firmware version are you using? I'm testing this on Cal table 1 and it will accept values between 44.3k and 3k.

Hi Scott.

Thanks. Sensor is reluctor yes.

Assuming the polarity is correct (or will be correct), do we have the other settings correct? In other words, should we see ECCS Sync "Yes"?


CAL Table - just updated to latest version and you are right. Thanks for clarification on that!

Thanks guys.

All sorted now... Somebody has been playing with the loom before we got the car... They had swapped the +/- wires half way along the loom! No idea why, but swapping them back has sorted the main issues.

3x dead injectors prevented us going any further though....

Lesson to be learnt here - don't take on jobs if you don't do everything from start to finish!!!
