I presume everyone who has Tracy's EC2 EFI/Ignition system is

aware

that

Tracy is offering an upgrade to its software.  A different (better)

starting

algorithm and perhaps most interesting an ability to adjust your

ignition

timing, all  for $45.  I shipped mine to him today.  See his website

for

more details.

Now if he would only add the waste gate control :-)

I just got my upgraded EC2 back from Tracy. It has a 35 degree advance

I had to do the Map table over to satisfy the new advance. But, I have

played with the new 'in cockpit advance adjustment yet'.

35 degrees? Wow!! Really Jerry? What is the theory on that Tracy?

Paul Lamar

Static advance in this case is defined as the point that the controller
processor is triggered, not when the spark actually happens.  Spark timing
at cranking speed has not changed and this "static timing"  has nothing to
do with the improved starting characteristics.

The controller also now has a manifold pressure controller timing boost that
can trigger the spark around 30 degrees BTDC at low MAP only (high
altitudes).   This improves BSFC  (same function as on thier Lightspeed stuff
for Lycs.)  The MAP threshold that this takes place is adjustable so it can
also be used as a boost retard function for you turbo and supercharged guys.
