View Full Version : Crash course on N75 Duty Cycle vs Rpm for electronic boost controller

Hello,

Picked up an PPD with the boost controller add-on.

Currently my car is tuned (MTM) to peak at 16 and taper to 14.

what Im looking to do is; in the 3 boost maps I would like to keep that same behavior (current tune specs) for the mid/DD/spirited map, a weak/valet map, and of course a "monster" map.

For the valet I want it basically stock, if not less..usually I'm the only driver to my car, but when it needs to be parked in a garage I would like to know they cant hurt the turbos. If nothing is requested of the n75 it boost to 7psi only. I figure that's plenty safe.

For the "monster" map I'm looking for something in the range of 20 psi peak, and 18-16 taper.

now how can i get those results based on the duty cycle % vs rpm?

does 100% mean it will give me what it can at a given rpm? do i start with a high percent and taper off or low to a peak, and then low again?

thanks!

Log block 118 for the duty cycles requested by the MTM software, and use that data as a starting point for plugging values into the PPD.
