    Before doing any tuning, fix your charging issue, or the way you're reading the voltage.

    12.4 isn't even maintaining battery voltage, you need at least one volt above nominal battery voltage to be...

    The ECM output for the fuel pump is on whenever there is a DRP (Distributor Reference Pulse, AKA and RPM signal), in addition to the priming pulse. The way GM set this up was that the fuel pump would...

    I was thinking more along the lines of the Sy/Ty and Code59 type boost control, which has worked well for me. The tables are there and allow for lots of adjustment.

    To be honest, I never had much luck with the 2 transistor cable, especialy when trying to adapt to USB. The two transistor cable only allows for TTL like signals (0 to a positive voltage) and most...

    There are two grounds for that WB. One is a power ground, black, and should be connected to the engine where the ECM is grounded (tying into the ECU ground nearer the ECM is also ok), and there is a...

    The ECM is not even in the mix for spark while cranking, so you can rule out the ECM being the issue there.

    The ignition will be base timing triggered directly from the ICM and crank sensor/dizzy...

    No, bad checksum will not brink an ECM, at least not OBD1 ECMs.

    No, checksum is only updated when the bin is saved. This is why checksum needs to be disabled during emulation.

    So are you saying...

    When's the last time you did a tune up?

    There's really no reason that a stock engine (assuming, since there's no indication otherwise), shouldn't pass emissions with a stock bin, though the lack...

    Most Hilborn conversions place the injectors on the inside of the manifold.

    Yes, add an IAC.

    I would also add a VSS (I missed your earlier post asking about any additional sensors)

    Yes, the 27SF512 will work in the '165, G1 is the adapter you need.

    It may be easier...

    Yes, the only difference between large and small cap is the size, effectively. The signals in and out are the same. GM liked to keep a lot of things the same.

    The math involved to run DIS requires a negative value for a couple of the settings, I don't recall the math on it, but mathematically it makes sense. It's probably the way the XDF was created that...

    I never did that by percentages, I just adjusted the BPW and the main VE table until I got a good idle, and leave enough room in the VE tables to stay below 100.

    Your fueling issue, if it's solely tune related would be because the combination of VE1 and VE2 are adding up to over 100. You need to keep this below 100 to not get to the VE limit.
