BIG MIKE - STOPPED BY SHOP & HAVE QUESTION

[YOTA864ME]

Hi Big Mike...

We stopped by the shop on Friday ....from San Diego....about the engine swap....one more question...

Are we limited in ECU's to just the year of the engine we are putting in???  We are putting in a 1997 engine 3RZ FE from a 4 runner behind a W56 1986 4 runner....

Can we use a ECU from any other year?  There is one from a 1998 here in San Diego but was unsure if it would work...

Thanks for your help
