14b swap on a 1g auto

[DC586]

I have a 91 auto awd and wanted to do the 14b swap and run around 14 to 16psi. I was going to used 450 injectors and a 190 pump with the stock ecu and no safc or anything like that. some people say you can and some say you cant. I searched and didn't come up with anything.

You can. who said yo cant.

with the swap to larger injectors you will need somw way of controling the duty cycle so as not to over fuel you motor. with the stock ecu programed to work factory injectors it will keep the larger ones open to long, puting too much fuel in the cumbustion chamber, there by running to rich.

you really need a way to tune for the bigger injectors

It is a lot easier to just use the stock ECU out of a 5-speed and then for at least the time being you wont have to tune anything. Since the ECU doesnt have anything to do with the tranny you wont have any problems.
