Hi guys, Im installing an s100 onto a ford 351w and the customer is wanting to use ls2 coils. I have seen some information in the past about how to make them work with the built in ignitors but I cannot find it anymore since the other board is down.
I know the following about the coils
connector at coil
a - ground to engine block
b - signal ground at ECU
c - Logic signal input
d - switched 12v input
From what I understand the signal required for the ls2 coils is inverted from what the DTA outputs? Does anyone have any information on how they have wired up these coils?
thanks

Re: LS2 coils with S100
Depending which is left and right, the two grounds a/b just run them to engine ground as per your schedulesnax wrote:Hi guys, Im installing an s100 onto a ford 351w and the customer is wanting to use ls2 coils.

And just check "external amps" in general settings.
c is the ecu trigger, wired in firing order.
d is an ignition switched 12v.
Re: LS2 coils with S100
Right now I have pin a wired up ground at the cylinder head and pin b wired into the sensor ground circuit...Will that damage the ECU?
I keep finding different info on these coils online, some say they trigger with 5v others say 12v. Any clear answer on this, if it is 12v I will need a pull up resistor on each spark output.

Re: LS2 coils with S100
I struggled with this also but very simple.
Pin A- Ground
Pin B- Ground ( I have used the same ground )
Pin C- Input/Trigger from ECU
Pin D- 12 volt fused constant power w/ignition on

Re: LS2 coils with S100
The clear answer is they will work wired directly to an S-series as already stated.snax wrote:Right now I have pin a wired up ground at the cylinder head and pin b wired into the sensor ground circuit...Will that damage the ECU?

Wiring the ground pin b to the ecu will do no harm.
This pin is normally used for missfire detection on the OE setup.

just the info i was looking for
thanks guys
