I have been using 8Dmod, but wanted to try s_aujp v4. I burned a new chip, with the 41026 4a bin. I set the cylinder volume and injector size, entered in my initial timing (12 btdc). In the flags, word 1 bit 4, I unchecked the box in VATS. The car would not start. What is bit 6 used for? I am not using the ECM to turn on the fuel pump, should I set that bit? Are there any other initial changes I need to make?

 

Bit 4 indicated to look for the VATS input or not.
Error word 3, bit 1 (VATS indication) should also be unchecked.

Disable the checksum with AA if your engine light came on.
Verify any error codes besides the normal "12" you may have and clear them before attempting to restart.

Thank you, I didn't notice that error bit.
