AE being... Ireally don't know all that much. Just enough to be dangerous.

Subject: [Diy_efi] Newbie questions on spark and PE 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
