Trying to get a 454 TBI running that's been installed with a 4L60E. Since there are no 454/4L60E calibrations I know of, I figured I should be able to transfer the engine parameters from a 454 calibration (BJKW) to a BJLF calibration. The engine runs with the stock BJLF calibration (not well, but it runs), but I get a no-start with the modified BJLF. I'm wondering if I'm missing something very simple here.
