[Diy_efi] Newbie questions on spark and PE tables

[Jim Sloan]

Sounds more like an AE problem than PE.  Does CATS identify any AE =
tables?

Short background... I am a GM driveability tech but have ZERO knowledge =
of
the programming aspect of EFI. I am running a '78 SB 400, CR9.5:1, =
1.94/1.6
mildly ported heads, mild RV cam (don't have the specs on me), headers =
and
an Edlebrock Airgapper intake. I'm using RT Tuner from C.A.T.S. and the
Moates Autoprom.  I have success in setting up my VE tables so my =
'normal'
driving conditions are fine. My problem is when I hammer the throttle =
for PE
mode. When I had my 750 Edelbrock, it would go like scalded dog. Now, it
just seems to bog. I've had it on the freeway with the emulator and =
adjusted
the PE AFR form the point of billowing black smoke to loss of =
acceleration.
Nothing in between seems to change the 'bog' it has. I haven't messed =
with
the spark tables yet. I'm trying to tune one table at a time. More fuel,
more spark; more MAP, less spark; I honestly don't know where the heck =
to
start. Since my chip was originall prog'd by someone else (who didn't
listen! to anything about the running conditions and data I was giving =
him).
I've managed to iron out all the VE mistakes, now on to the rest. I need
someone whose willing to help me learn. I'm told, this is the place. =
Thanks,
Ski
