IS A 91 ENGINE COMPUTER FOR A Q45 COMPATABLE WITH A 95 ENGINE

Each Single year had diff versions of the ecu. California or 49 states, standard or active suspension, and traction control.

Starting in 94 they changed crank angle sensor designs and added EGR temperature and changed the ignition control modules.

We have never even tried to swap a 90-93 engine in a 94-95 [or the converse] because of the differences.

it took days of work and had to redue it 3 times with lots of skeptocism and a few mods but i finaly got it to work ran everything from the 91 and even modifyed the old timing senser bracket to fit in the 95eng and it worked

Great job!!
