the first few pages were just arguments so I just skipped ahead , so if this was discussed my apologies. This thing looks essentially like a boost controller, is it not? It lies to the computer about the PSI being seen and ups the boost by a small amount. or do i have this wrong?
Yes, you are 100% correct. It intercepts the boost signal and delivers a lower voltage to the ECU giving you more boost.
I have results on 91 Octane. The rpm pick up was flaky at the higher rpms so the chart looks a bit funky but it is what it is. I have spent way too much on the dyno now but it is finally nice to have numbers to post and here they are --->
On a Fiesta ST, the gain is 20
wheel lb-ft of torque. The gain at the peak is 6
wheel hp and a 20
wheel hp gain at 3500 rpm.
On a Focus ST, the gain is 40
wheel lb-ft of torque. The gain at the peak is still 6
wheel hp and a 25
wheel hp gain at 3500 rpm.
Not sure why .4 L of displacement doubles the torque gain but that is just what I measured.
And now the part you have all been waiting for - the dyno charts ...
