Swapping a stock tbi l19 in my 92 half ton 2wd with nv4500 and 3.42 gears. Currently have a 299 ecm but am gonna replace it with a 1227747 ecm i have here on the bench. I know ill need an ESC modual for a 7.4 and a memcal for the 7747 to work with the big block. I see bins here and cant justifying purchasing a willem or other device to burn a stock chip. Was wondering in anyone would have a stock chip or would be willing to burn a stock chip and ill gladly purchase it from them. Im quite capable of doing the swap as i did the swap on his 1995 yukon to a tbi 454/t350 but required custom programing from tbichips.com. This one should be a basic swap.

Maybe the attached '7747 .bin file would be a good option?

Now if i had someone who would take my money and burn it on a chip for me! One thing got me thinking tho. I cant remember if the 299 ecm has an esc model i know alot of the 7747 did..but dont know if the 7.4l has an esc mod. Any light?

So have located a 7747 ecm with the bcc anua and seem to not be able to find out anything about it. Kinda worried that it may be running an esc modual and this truck does not even have a provision for one. An anyone shed some light on this bcc?

Some / Most of the 1987 454 TBI engines did not use a knock sensor.

See attached .bin files.
