DTAForum.com - a forum for the DTA ECU

Hi there,

im installing a DTA S40 system onto my BMW 4 cylinder M44 318IS Engine,
ive just a few minor queries that i wanted to get cleared up....

1/ im using a 36-1 crank trigger wheel and the std ford 2 pin sensor, what way do i need to time the wheel, ie, does it need to be at 90 degrees to the missing tooth? or is there an exact ignition timing figure i should be setting it to?

2/ on the ford 4 pin wasted spark coil i have, according to the dta manual pin 1 is coil1, pin 2, coil2, pin 3 12V but it says "NC" for pin 4? does this mean no connection?

any help would be greatly appreciated,

Chris

1/ Angle is set in the software, so wherever is convenient pretty much.

2/ NC is no connection.

The manual does have a wealth of information, which hopefully you've read. If not, I recommend going through it a couple of times.

1. yeh set the trigger wheel so that the gap is 90 deg BTDC on cylinder 1. You will never get it 100% right so that's why you need to check with a timing light once its running. I get confused with wasted spark doubling the reading on a strobe light, so I get the ecu to fire at 0 deg BTDC, you then need to tweek the crank sensor position setting in 'general engine settings' so the timing light displays true TDC on your crank pulley.
2. yeh as others have said NC = not used, this is probably some sort of misfire detection.
