Chris: I don’t know anything about the emanage ultimate other than some people are finding it hard to get a tuner for them. Cihan is one of the resident Emanage gurus
All I know is that I like my microtech Also, 4 out of the 5 quickest 1jz powered cars in Australia are using one. I know that doesn’t tell the whole story about drivability but from what I have heard all have been happy with that also. I will be starting my tuning tonight so will have some more info. soon
Paul: check out www.supraforums.com and go to MkIII then 1jz/2jz section. Lots of guys in the US making big power on basic setups like single turbo, stock ecu, FCD and safc. One guy just made over 500rwhp with that setup. (dyno jets do read higher but that is still around 300rwkw on our dynos)

Hey thats great news, make a thread about it will ya. Hopefully that 45' wakes the •••• up and makes some big ponies!

Guys you cant use a 3BAR map sensor in conjunction with the stock ecu without proper piggyback management. And it definitely wont work (edit: work well enough, for my standards)with the safc-II.
The thing is, the new MAP sensor is still a voltage input from 0-5 volts with a 2.65v atmospheric pressure middle point. The only thing thats different is the resolution either side of these points.
The stock ECU will engage boost cut when the MAP sensor output is 4.82v no matter what you do. On the stock MAP sensor that corresponds to 14.7psi, with the 3BAR MAP that corresponds to 29.4psi hence, you can run up to 29.4psi before boost cut occurs.
If you plug in a 3BAR MAP without doing a complete retune of all load points between 1.0v-5.0v and 0-8000rpm, it will run lean and you will blow your engine before reaching 1bar.
So dont try it without an E-Manage or powerMOD installed and dyno tuned with the new MAP sensor.

Firstly id like to correct my previous post by stating that boost cut occurs at about 14psi which corresponds to ~4.33v and can be eliminated by setting the FCD to 4.32v or lower.
To answer your question - think of a FCD as a limiter. Upto the point it is set to, it makes no alterations to the MAP output the ECU reads.
It will only lean out the AFR if you run more boost than the FCD is set to.

The clamp is setup a bit differently on a powermod. Of the two cars I've had them installed on, a run a stock boost level was done, finding the max voltage, which was clamped at that voltage. So basically factory ecu would always think it was stock.

You can do that of course, then make fuelling and timing alterations directly via the injector drivers and based on the cam and crank angle sensors respectively. Can be done with the EMU like this also
