has anyone done it? i am just concerned about the ecu part. could you still use the same computer?

5 spd conversion i've done but we installed a gte motor at same time so we used an aem technically you should use the manual ecu as the maps will vary a bit from auto to manual not saying you can't use it (auto ecu) but i
d personally prefer to use the manual whic h would have the proper fuel maps and timing

you would not be able to use the 5 speed ecu on urs.

1st: you have the VVTi engine which never came with the 5 speed to begin with.

2nd: if you put on a 5 speed ecu from either 92-97 sc's then ur engine will not run proporly or at all due to a totally different wiring harness.

3rd: it will probobly not even plug in because of the different wiring harness.

4th:if you stay with the auto ECU then your check engine light will always be on for transmission sollinois codes because they are missing ( no more auto trans) lol.

has anyone looked into doing an is300 2jzge 5sp ecu swap. the ecu plugs might not be the same but a little time with two wiring manuals can have this solved

i dont see that being that much of an issue.

I was going to suggest the IS300 ECU as well. I would have thought everything would have bolted up the same...but i guess the plugs are different...=(

ah okay. yeah i guess this is out of question then. thanks for the info guys.

a local guy did this conversion, you dont need to change the ecu. just swap in the trans, and your set

I just got all the parts and according to my research, you only need to wire up your P N switch so the ecu thinks it's in park all the time.

For what year SC? They vary. I did Baoser's auto to 5spd on his 97 and it ran fine on the stock auto ECU. But if you want to get the best performance out of it I'd suggest the swapping to the manual ECU. But like I said before, its still do-able. Good luck.
