    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.

    Size the injectors to your expected power. There are a few ways to mount and plumb them, welding in bungs and then...

    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...

    Since you plan on going turbo, and you need to start over, I would start with a mask that will work with boost now.

    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.

    You can...

    It's more than just connecting a USB cable to the OBD connection. There's an interface circuit that is needed.

    I've used a JimStim for years for this. It's marketed to Megasquirt users/builders, but adapter harnesses are easy enough to make. I have several for different OBD1 GM ECMs and even one for a Nissan...

    There are higher voltage systems and alternators to suit. Some drag racers use 16V systems, that will typically charge nearer 18V. Some run no charging system at all.

    Ignore the hardware not found error, that's for emulation devices, like the Ostrich 2.0 and AutoProm.

    You need to go into preferences and set everything for the cable in there.

    I have found one of the best tools to use for someone to understand the changes made to a tune/BIN is to use an EPROM emulator, like an Ostrich 2.0 or AutoProm, which it sounds like you didn't buy.

    Yes, you still need to program the EEPROM with the proper offsets, then the hardware offset (shorted pins) allows everything to work together.
