Well, here are the preliminary results for the MAP/IAT Adjuster Box that i've designed to work with the Powerdyne Supercharger systems. Since our MAP Sensors are not a 2-BAR, an alternative method was required to readjust the MAP signal. (Under boost, it reads 30.8"hg causing a nasty lean condition under light boost/throttle and also leans out under WOT due to the last known MAP voltage reference before going into Open-Loop.)
-------------------------------------------------------------------------------------
Bruce Bridges: Has the box - Not installed yet. (Will be taking to Dyno for testing)
Tim Berry: Has the box and installed - Preliminary report...Had to readjust the FMU to an 8:1 plate (from a 12:1...running too rich under boost). Also improved his shift points...don't know if this is an after effect or just a coincidence. Runs much stronger.
William Phelps: Has the box and installed - Preliminary report...MSD BTM turned back down to 1 (was at 2.5). Runs much stronger.
Richard Pyburn: Box has been shipped - Waiting for delivery and installation.
Myself: Installed Revision 2.0 of the box (two piece instead of one piece) and removed the MAP check valve. 50mm TB now has no problems at all with part throttle "stumble" and will be installing the 10:1 plate (removing the 12:1...running a bit rich under boost). Very strong on part throttle acceleration now.
The IAT adjustment has been set to a range of 16 - 190 degrees (no need to go below 10...there's no change in timing or fuel delivery) and the adjustments can all be changed from 1v - 4v.
I'll be posting again in about a week from now with more results on the box. So far...it's looking REALLY promising! :)

More results coming in...
Tim Berry has tested it on the Dyno and just the IAT adjuster alone gained him 12HP at the rear wheels.
