Standalone ECU

Has anyone looked into this idea?

I am planning on building a desert/rock truggy starting next year, and hope to use most of the parts from the truck including the engine. However, I really would prefer to switch to the 6-speed manual tranny but I know that the computer would freak out left and right. My understanding is that there are different ECU's for different engine setup's. Since I will only need the computer to run the spark and fuel, I was thinking a standalone would work to overcome the issues of different ECU's for different combo's of engine/tranny.

I started looking at something like this.
Infinity Stand-Alone Programmable Engine Management System - Wideband O2 UEGO, Water/Methanol, Stand Alone Engine Management, Piggyback F/IC, Tru Boost Controller, Gauges, Automotive Performance Electronics

What are your thoughts?

Couldn't you just get the transmission and associated computers out of the same truck and swap them into yours?

^ not sure. Again...my understanding is that there are many different ECU variations and may not work with a direct swap. Plus, I want a simple ECU setup, not the crazyness we have now since I won't need a lot of the features that come with the truck.

stand alone may be the way to go otherwise the stock ECU even one that was programmed to be paired to a manual trans, would be looking to maintain emissions as well. you dont care about that for an off road rig. so a stand alone would maintain the electrical requirements for the motor as far as the stoichiometry and temperatures etc. but wont bother to try and maintain the proper emissions limits. or at least, thats how i understand it. perhaps im wrong?
