EST signal output help

ASRoff · Post by **ASRoff** » Thu Mar 30, 2006 4:09 pm

I am useing an LTCC box to control 8 coils on an LT1 I'm trying to use the orignal opti to send signals to the megasquirt2 (this is complete on the board as per the instructions).

My question is I need to get spark control signal from the mega to the LTCC box.

It will function like a module. how do I set the circuit up? do I use the HEI set up?

ASRoff,

Which instructions are those? There's certainly nothing in the MS-II manual about the LT1, though some people have managed to convert them.

For the LTCC box <http://www.bailey-eng.com/LTCC.html> (which is an aftermarket conversion for LT1 to LS1 coils), what you need to do to MegaSquirt-II depends on what the LTCC box wants for an input signal.

So I would email Bob Baily <turbobob@bailey-eng.com> and ask him what sort of signal his LTCC wants.

I set it up as per http://www.megasquirt.info/ms2/pickups.htm

The LTcc eliminates the ignition module so I need to send the proper timing signal direct to the LTCC.

From what I have read in the electrical service manual the old LT1 module works like a HEI module.

If thats the case I need get megasquirt to translate the signal from the opti and send out a signal like a HEI.

I already contacted bob and he said that It shouldent be a problem, He said the box has been in use with both Fast and accel DFI without problems.
