I’m having great fun trying to program my EC2. But I would love
some input if anyone has any ideas. The situation so far is thus:
It runs really great over about 18”MAP. I had it up to 23 “ today and
I almost couldn’t keep the tail down. I am running the stock turbo II.
I’m not really sure what the pressure was up stream of the throttle
body but I think it was more than ambient as one of my manifold
temp sensors (held in place only by RTV) got popped out of its
hole. Manifold temp at the time was about 32C.
I’m not sure what RPM I am seeing because I haven’t been able to
get the tach working yet (hey Tracy – do you think the signal output
to one of the LS1 coils could be run in parallel to the tach?)
Other parameters include (so far) max coolant temp 38C and oil
60C but that was after only about 15 min. at 19”MAP.
I definitely need a bigger coolant reservoir. I hold just under to
quarts now and it is still overflowing without even getting very hot.
The turbo does get very hot and makes some smoke (not a lot) out
the tail pipe on shut down. I am wondering if maybe the oil seal is
leaking. How much smoke on shut down is normal?
The biggest problem continues to be very rough running anywhere
under 18”MAP. It really won’t run any lower because of and bucks
and surges (but it runs really great above that MAP). I am thinking
that the problem is the injector transition. As I recall Rusty had a
similar problem but I can’t remember how he fixed it. I am tempted
to use some sort of artificial devise to set the transition down very
low and just avoid any need of a transition. Anyone have any
ideas on a simple way to suck the manifold tubing down lower
than I will ever run the engine long enough to set the EC2? I have
not been able to get it lower than 14”with the engine, and that is
difficult and unreliable.
Thanks for the help all.

Thanks Bill. I may
change over to one of these at some point.
Cheers,

hummmmmm-less)
