norbs,
I just tuned a friends cobra a few weeks ago with the TEC 3. First of all, there is no WB controller built into the TEC 3. We used an Innovate WB setup and then feed that signal into the TEC 3. Otherwise, the software has some pecularities when compared with the FAST system.
1) You can only change one data point at a time while the engine is running. (this sucks when trying to get a large ran dialed in for the first time)
2) you can record data while driving, but the plotting of the data SUCKS! The TEC 3 has a data viewer, but you might as well go into Excel to look at it. Then, of course, you can not overlay the data on your maps like the FAST can.
3) Tec 3 has the availabilty to auto tune the VE maps. THis can be done while driving or back at home using the logged data run you just took. (kind of nice feature)
4) The base VE map is setup based on maximum engine pulse width info .... I am not going to try and explain this, as it gets WAYYYYY too complicated. Basically, you have a VE map, but instead of just putting in 57% VE, you have to put in +7%. And you are allowed up to +/- 50% (I think) ...... Whatever, the thought process behind this is just plain F'n stupid, but the functionality works similarlly to the FAST VE map.
5) You can control many more inputs and outputs based on other map settings. These would be useful for turning on an alcohol injection system.
6) The unit has a built in knock sensor controller for use with a GM knock sensor. The FAST makes you have a stand along box then feed the signal into it .... PROVIDED you are a batch fire

not Sequential setup.
7) There are some unique idle tuning strategies to get it to idle "smoothly" with a lopey cam. Bascially it tells the MAP sensor to go away, fixes an injector pulse width, then adjust the timing +/- a few degress to smooth out the idle. This would be a SWEET option for FAST to add to their existing software (HINT HINT!!!!!!)
I cant think of too many else off the top of my head. If you want, email any specific questions and I will try and answer them for you. I have a copy of the TEC3 on my tuning laptop at home.
