How do you know when its time for a new ECU?
I think my 93 ssei may be in need of a new computer. How do you know when it it time to change? If so can you put a 94-95 ssei ecu into 1 93 ssei

Short Answer on changing the PCM from a 93 style to a 94 style, no. Connectors are different as the 94-95 style is the OBD 1.5 Hybrid. There are many other differences as well. The 93 PCM is alot easier to work with, and is upgradable easily with a Jet Performance chip, only if your modded enough to need it.
What is yours doing that makes you think you need a new one?

Rather than us tell you the 100 different things that may lead to a bad PCM (powertrain control module, called this because it also controls the transmission.....the entire powertrain, where an ECU only controls the engine), you should tell us your symptoms and we can troubleshoot it from the ground up with you.
