yeah i have found the stuff on the diy-efi website. most of it it actually 
useless garble. i geuss i going to have to find a cavalier and get a couple 
of probes out and use the osciliscope. im sorry others have let you down. has 
anyone ever checked the output of the ecm to the module ??? i keep hearing 
that the duty cycle is 50% or so. also that is uses a high low refrence. 
formt eh schematic i looked at it was pretty simple. the module handle all 
the tpu need for the coil firing and the ecm simply provid a command siganl. 
just like a normal module on  hei would. i think yr battle is in the ref 
angle and the output signal. ill be a nice guy and get a couple of shots of 
the actuall dis module runnig on a car and comapare it to a normal hei shots. 
the answer has got to be pretty simple. ill get back to you in a few days. my 
question was basically has anyone done it and did it work. i got 

 no and no . 

  thats ok. ill get it working or at least figure out why it doesnt work. but 
if i can provide you with why the pid loop doenst work can you help me recode 
the 749 to operate properly. ???im pretty sure the answer is under our noses 
staring us in the face as always.
