It doesn't, but you can change ratio targets on the fly through a laptop. The Banshee software application has a gauge screen where you can monitor data in real time. This is also how you would generate datalogs.So does your standalone controller have different modes you can choose from so you could kinda have a, normal position,race position, tow position?
The draw back in coating the inside is the ring has to be cut in a couple pieces to get it out, that requires a new ring purchase..When talking with Steed while troubleshooting an issue with my setup (it ended up being a dead actuator, no issues with the Banshee), he said most dealerships will remove a nonfunctioning turbo, throw it in a scrap pile, and put a new one back on.
I'm interested to see how the coating does on the interior of the housing, I would be interested in this if it does what we think it will do. I'm also interested in how much of a difference a thermal coating on the exterior of the housing would do as well. I have a PTP turbo blanket on the housing right now, but it would be a second option for thermal control under the hood.
