TBI Chip 1983 CJ 7 with 1990 350 TBI having chip proram issues

Nice build!

I have a few questions, but first did you data log to get the custom chip?

What is your fuel pressure?

If you set your timing to other then 0 then it has to be accounted for in chip.

Are those heads Vortec or TBI?

Why did you choose a Marine Cam?

Knock seonsors are your friend, you can add one.

No I did not data log to get program (was not recomended by TBI.Com)

Fuel is 18 to 19 psi recommended by TBI.com

Did run while at @ 0 but it would fall on its face when I would try to accelerate so Brain recommended advance timing as much as 12 deg (seemed wrong to me but I tried it and it helped)

Yes I now have vortec heads.

I explained my who build to comp cams and they said this cam would best fit my needs

When I first did this swap with the stock TBI motor several years ago Affordable Fuel Injection recommended me doing this way and the wiring harness was not built to add one in.
