Hello, I am the new owner on a 88 SR5 4WD 6 speed Terk with 176,000 Kms. I am interested in converting the 3A to EFI. For the many benefits of EFI. Was the 3A ever produced with EFI?

Do you have the OEM settings for the ignition timing ?

My distributor is a bit worn, I'm not sure of the centrifugal advance.

As worst gas I can get is 95 Ocatne, so I raised the static advance from 7° BTDC to 10°.

I'd like to know the whole curve to check my tuning.

OOps !
