MWDesign “Darth Maul” M3 gets Vishnu Procede PWM Meth Upgrade! 543 WHP 362 RWTQ

Submitted by on September 23, 2011 – 5:32 PMNo Comment

First two runs, with perfectly cooled engine (with Procede and meth disabled):

Then we simply turned out the PWM meth system. Unlike traditional meth systems, this is metered with a high speed valve which is controlled by the Procede. No changes to actual tuning at this point. With meth on, we picked up some good gains:

Next, we tweaked AFR slightly and added a few deg of ignition advance (via Procede). And since the Procede controls the tune as well as the methanol system, this extra advance and revised AFR only comes into play when methanol is flowing (monitored by flow turbine tube generating a 5v digital signal via hall effects sensor). More power was picked up:

“Adding a Procede+PWM Meth kit on a mildly boosted M3 that ALREADY has a intercooler was worth as much as 80WHP up top. With nice gains everywhere. Furthermore, the results were consistent and very resistant to heatsoak. Which makes the real-world performance delta even bigger.”
