We have a bunch around. I would highly suggest ditching the TecII, far inferior design, and a bit sketchy in my eyes.
I tuned on the TecIII a bit on our dyno in our shop here, and I recently tuned a bit on some prelim runs with this new ecu we're trying.
Basically, an engine with stand alone will only be as good as the guy behind the computer tuning it. You NEED lots of dyno time to get it right, plus setups for all conditions when you are running the car.
The purpose of using a full stand alone system is for the extra features and extreme fine tuning thats not available on most oem ecu's. For example Most Bosch systems tune every 500rpm's, while tec/motec goes every 100rpm's. This allows for better driveability and peak power.
I recently had switched out the Motec in my m3 racecar for Boshc oem setup dyno tuned of course. All you need is a Bosch computer, or you can even make one yourself if you have the knowledge! I lost zero torque, however a bit of peak power... but for the $7500 the motec cost, the 15bhp peak loss is doable. It also lost a bit of driveability, but nothing too bad.
We have a tecII, and TecIII laying around, however I think they are spoken for. Wealso have a tecII on the 2002 car, however It will probably be sold with the car.
We should be tuning our new ecu on our worked cbr600f4i in the next 2 weeks upon completion of the car. I am hoping we can make 75hp.
If you'd be interesting in watching us do dyno runs, we usually start in the morning and will do a shitload of runs that day, sometimes several dozen in an hour
