Ok so i'm reading thru thedodgegarage.com and i came across this...

"In 1989 Chrysler added 4-wire Oxygen sensor to all engines for more precise fuel control and changed the software code used in chip- 88 SMEC is based on 87 LM code! The SMECS are still interchangeable between the 88 and 89 model years however assuming the correct injectors and engine displacement is observed... And as before the Turbo I and Turbo II SMEC are the same units except for the software "burned" to the chip."

What i'm mainly interested in is this..."And as before the Turbo I and Turbo II SMEC are the same units except for the software "burned" to the chip"

What software is "burned" to what chip? and what does it do?

Thanks,

Chris

The software burned to the chip is the code and data that actually runs your car. It reads the sensor values and decides how much fuel and spark to give your engine.
