Ok im new and ive been doing a little looking and talking to a machinest about doing a turbo conversion on my escort. My question is can a thunderbird turbo coupe computer be used on the 1.9 if the harness is reconfigured to accept the comp and aditoinal sensors. I have a ranger that im putting a turbo coupe engine into but i also have a second harness, comp, and engine so i was going to use most of the sensors, injectors, and comp to convert the escort to turbo.
Thanks for any help

Well... it's more complicated than just hooking up your 1.9L SEFI stuff to the appropriate terminals on the thunderbird ECU. For example, the thunderbird could use peak hold injectors whereas the 1.9L SEFI uses saturated injectors. Basically... the only way to ensure that you get everything to work is to take EVERYTHING that is connected to the thunderbird ECU and adapt it to the 1.9L SEFI. But by the time you've done that, you're using maps for one engine on a different engine, so your performance will go to hell.

If you're really serious about turbocharging, I suggest you read up a little more. There are much eaisier ways to go about systems management. The cheapest and easiest being fuel pressure risers for fuel management, and something like an MSD 2.0 for ignition. Then your boost control comes with aftermarket drop in stuff.

Swapping over sensors from other cars is possible, but you'd have to do weeks and weeks of research. You'd basically have to go in and see how both of the ECUs work, then figure out a way to have the two communicate with eachother, all while preserving good fuel and ignition maps and compatiability with your sensors. Stuff like that requires a deep understanding of electrical and software engineering, and you'd probably have to design new circuitry to get the two ECUs to work correctly together.

Is is possible? Yes. Is it feasible? Probably not. I think the differences are probably significant.
