Default OBDI vs OBDII re: 5spd swap

Hey guys, I'm still in the planning stages of buying my SC300 and doing a 1jz or 2jz swap on it but I am having a bit of trouble finding information.

I see a lot of 5spd swaps for sale on craigslist, or even on here, but I'm wondering....due to the fact that I really want a car to be in good shape interior and mostly exterior, I've only come across 96+ cars with OBDII and automatics that are to my standards. How hard is it to swap in a 5speed say an r154 into one of these cars considering it must be next to impossible to find a 5spd ecu. Whats involved in the 5spd swap besides the obvious, clutch master cylinder, pedals, some interior pieces etc.

I am planning on using AEM EMS , but considering a few other engine management systems, just wondering if this will alleviate my concerns with trying to find a 5spd obdII computer? Can the aem ems or any other ems replace the need for a 5spd ecu ? or will a piggy back system attached to the stock auto ecu take care of that as well?

You don't need a 5 speed ECU. An auto ECU works fine - I'm running my auto ECU in my swapped 5 speed. Of course, you may have issues with emissions - it will throw a code. In AZ you fail OBDII if your light is on - even if unrelated to the engine. GAY That's why I bought a 95.

5 Speed swap to W58 is pretty easy. Search on R154, I can't speak from experience. You forgot driveshaft and flywheel on your parts list.

The engine runs fine on the swap....the problem is that you will trip a code on the OBD2 cars because it looks for the auto tranny.

Using the manual aristo harness and computer will be the work around. You may also want to look into a standalone as well.

There are several issues to overcome. No cruise, memory seats, neutral safety bypass and - the O/D off light flashes which is because there is a code for no signal from speed sensor #2.

Memory seats is the reason why you're holding back from doing a 5spd swap?

Lame reason.

OK ...so i do plan on going standalone, as i think its just a better idea. With a standalone, can you program out a lot of the problems? and the CEL will that work? I have NO experience with standalones, so just wondering what they can do.
