Note that these assembled bytes also incude the neccessary portions of the intake air temp sensor diagnostic routine to avoid getting a code.
If you want to try this, insert at 0x935E in the 607 automatic binary, or search on the byte pattern 90 F1 96 E4 93 70 0B and overwrite with
the above bytes starting with the 90 (place the 75 AA on top of the 90 F1 and continue on...) -- Remember to update the checksums!
