Where were you like two weeks ago, Louis? I bought an aftermarket crank that came without a reluctor wheel. And I happened to be very dissapointed that I was going to have to pay $200 for the goodson one when I would be using it once. I was going to end up having my buddy machine one, but this one is a steal.
SBCamaro it has to be heated to 450F. And I have heard it needs to be within twenty-thousandths. Thus needing the alignment tool, or else it throws a code. Good luck, and my build should be coming together alot sooner than I thought

All callies cranks are +/- 2*, fwiw. Keep in mind, every one can be different, and they are. I have personally never heard of them being off and causing a code, but its not to say its impossible.
In the World Challenge cars, with a 3 car team, we had 8 engines. All were identical, but not one had the same timing. Most of the time, you can get them very close, but its not uncommon to see them off.
In the Bosch ECUs for the GT2 car and Late model WC cars, we have a global timing offset modifier- "Dwzapple" is the german acronym for it. This is the total offset this particular engine has for timing in relation to the "perfect" timing needed. each engine is labeled with the offset, that way when they come off the dyno and go into the car, or shipped somewhere, the engine calibrator at the track knows where to set this one.
Rather change the whole table, we just change the offset
Sorry for the novel.

Agreed! Be sure to check it. We've had aftermarket cranks from two of the bigger and best known manufacturers of cranks on this forum with the wheel on backwards. It's not a fun situation!
