I was wondering what i need to do to switch over to a carb after having a tpi setup on a 91 formula. We are in the process of building a 415 stroker motor and I want nothing to do with a computer system to screw up any throttle responses, fuel mixture, WOT ETC. Can you guys help me out???

 

C'mon guys, am I going to have ne comp. problems after going to the carb? I mean with the o2 and dash lights

 

There is a tech article linked from the thirdgen.org homepage that describes what needs to be done for the conversion from EFI to carb (also in the "read first" sticky at the top of this forum). Any details missing can be found by searching.

Why would you have O2 issues?

Your SES light will come on unless you do what it takes to keep it from coming on. Other dash lights & gages won't be affected if you hook up the sender wires properly (i.e., the way they were) when you put the new engine in.

If you have auto tranny and keep it, the torque converter clutch won't be operated by the ECM any longer. You need to get that functioning or you'll burn out the tranny.

Better throttle response with carb than EFI? Usually not.
