I expect there are a class of folks waiting for a reason before we put gauges on, and for whom the combination of gauges and fueling in the same box is an ideal combination. The protection afforded by EGT-monitored fueling is an outstanding contribution in my opinion. thats one of the things I'll be looking for in the Edge and the TST boxes -- the ability to monitor EGT and boost, sort of an Xmonitor with fueling. Also important to me, since I'm a tweeker by nature, is the amount of control which the user has over the box. (I'm one of those who bought a comp box for my 2nd gen, and then used it only in EZ mode). So the more control I have over the box, i. e. the configuration choices I have, the more pleased I will be.
And for the handshakers, there is no need for transmission temp; EGT and boost may be the only necessary parameters to monitor for moderate bombing. A single little box inside the cab; no need to remove a DOT registered safety device (the grab handle) to make room for gauges.
I think it will also be instructive to wait to purchase a box until we know more about the 04. 5 fueling. who knows, the box mfgs may learn something by studying the 04. 5 and that knowlege might make its way back into the 03-04. 0 boxes.
As for Edge concentrating on the Ford first, and with appologies to whomever coined this expression first, it appears that Dodge took Edge to the prom, and Edge left with a Ford.
At the end of the day, its the performance of the box that matters, but along with that, its important to me to understand the philosophy behind the algorithms. For example, Mark @ TST probably has more relavent Cummins experience than anyone, from his previous employment, so those connections are of interest to me. When Mark says he's not comfortable raising rail pressure, and that the amazing opportunities are there in timing and duration, that speaks volumes to me. So philosophically I'm closer to the TST approach because I prefer not to raise rail pressure.
