OrangVirus Tune for Skyactive Turbo

Just wanted to let you all know OVTune offers recalibrations of the OEM ECU in the CX9 to help boost torque output and horsepower even further.
We know the engine feels absolutely amazing stock, with peak boost pressure coming in right at 2000 RPM, However during our testing, driving and development we noticed that after about 4000-5000 RPMs the engine simply "feels tired."
Well that is only because of the stock ECU Tune. The ECU simply "dials back" boost pressure quite a bit after 5000 RPM and limits boost pressure from 4000-5000 (mazda is notorious about doing this to limit generated heat, however from the many years we have been tuning the skyactiv engines, we have seen time and time again that the stock ECU tune is too aggressive in reducing power as the amount of additional heat is negligible. For example in the MX5 we have seen consistently 30-40WHP gains with no overall increase in temperatures)
**Note** We do NOT remove or modify any stock SAFETY parameter of the car. All safe maps are still in place and work as OEM, we simply recalibrate the "working maps" (main maps the ECU uses for driving under normal conditions) to bring the engine to it's peak potential.
Our 91 octane recalibration offers:
- steady boost control. No sudden power drop after 5000 RPM. A clean boost taper from Peak boost to rev limit. Peak boost pressure of 26psi (18psi stock) 91 octane only for peak boost.
-Fueling adjustments. Stock fuel requests are extremely rich, simply by cleaning up all of Mazdas wasted fueling (to maintain cylinder temperatures..which is a feature brought by the Naturally aspirated Skyactivs, however the turbo sky doesn't have this same issue with EGTs / Cylinder temps).
- Ignition timing adjustments to clean the power surge and drop off from 2000-4000 RPM.
Camshaft adjustments. These engines utilize full time, "on the fly" camshaft timing adjustments. We recalibrate the VVT for better fuel economy out of boost, more low end torque, and cleaner acceleration.
We understand this is a SUV and not a sports car, which why our tune is dedicated to maximizing power when needed, and maximizing efficiency in low boost or out of boost scenarios where MPG is the main concern.


OVTunes 2.5L Skyactiv Turbo Recalibration on 91 octane expected gains (flywheel)
80-100 ft lbs increase of torque at 2000 RPM with more than 50 ft lbs increase overall.
50-60 Horsepower

we are starting development for the 2018 6 turbo this week. We have been working on the CX9 for some time now working on elimination the various torque limiters in the ECU. Mainly throttle reduction limits to bring more power.

CX-9 2.5T

This was done a couple of weeks ago. The owner is silently happy right now. I think they are still tweaking something as they don't want to disclose the Dyno results.
