And if anybody cares to dig up the datasheet for the chip in a 2001 Isuzu rodeo ECU, it's 58x, same pin count, same CPU as a P01, same flash as P59. Not a direct drop in though, physically larger package.
Outward appearance of ECU is identical to a P01, size, shape, plug color.
Don't get too excited thinking you can just put a p01 OS on it with some light modding, it only has the hardware for V6. And no IAC. Rodeo uses a motor similar to drive by wire, but only for idle control. There are some unpopulated solder points that look like it could do V8 if soldered on and software modded.
Bought one a few years ago thinking I was getting a lesser known P01 for just $30.

Believe so. Might be waste spark. Definitely not a distributor spark setup.
