diagnostics... old toyotas don't require the plug in computer as the plug in computer don't actually recognise our diagnostic systems
do as above, go read your codes
put a wire in T & E1 or in some supras it's TE1 & E1
watch the check engine light
code 51 will be like this
flash flash flash flash flash....... flash
code 34
flash flash flash....... flash flash flash flash
pretty easy, now go do it
oh and you can't replace "chips" in toyota ecu's, it just doesn't happen... hope you didn't give them too much cash
report back with your codes
