Hello all ... new member here, enjoying your digs ... anyway on to the question.

After having searched and read over the archives here and on similar sites, I am still unsure about one thing regarding the swap.

Here's my situation - I have a '93 P/U w/ 5speed and 4x4 of course. I have located a '99 4Runner with the motor package that I need, however it has an automatic tranny. Will I be able to use the ECU from the '99 in my truck, or will I have problems with it? Will the computer be looking for the auto tranny, not find it, and have a fit? And, what about the tach, I am unsure about how that receives its signal as well.

Below is a quote that I pulled from another member's archived post ...

"Toyota changed the 3.4 setup somewhat in the 99 model year. They ran larger injectors and ditched the cumbersome MAF used previously along with the EGR system. The 96 4Runner was capable of supporting the supercharger, but in order to take advantage of all the cool upgrades they made, you would ideally find a 2000 - 2001 Tacoma or 1999 to 2000 4Runner. To my knowledge, these are the ones that ran the larger injectors, no EGR and no drive by wire throttle system. I would avoid the drive by wire system as it would represent an additional pain in the as$ to wire."

So it would seem from that bit of info that it would be possible to use an ECU from a standard tranny vehicle if I had too. I would prefer to use the ECU that came from the 4Runner that the motor is coming from, but if it won't work, it won't work.

The ECU is included in the package deal that I am getting, and introducing a part (ECU) from a different vehicle and possibly a different year model could increase the difficulty of the swap by adding variables. I would like to limit the chances of pesky problems caused by mismatched parts and minor differences between models as much as possible, hence my desire to use the ECU and motor from the same donor if at all possible.

[color:"blue"]So, will an ECU and motor from a '99 4Runner(3.4L) w/ auto tranny work in a '93 P/U w/ 5 speed tranny and 4x4? [/color]

TIA for all info and replies.
