STILLEN 370Z Supercharger System - Announcement!!!

Phimosis

The version of the Uprev software they are using is different than what Uprev sells to the public. It's a locked down version that prevents the user from changing any parameters.

It's set up so Stillen can change anything they want, send you the tune, then prevent you changing settings, burning your engine up and then blaming them.

What I was told is that Uprev designed the software a few years ago, but then never brought it to market because the demand wasn't there. So, it had never been widescale tested in a public release. When Stillen implemented it, there were some factory settings that they weren't able to over-ride, like injector dwell time on hot start. Then add larger injectors with stock dwell time and your mix is way to rich at start up, causing the hot start difficulty. So Stillen's engineers were trying to work around road blocks in a product that is different than the user-tuneable Uprev, which is why Uprev sent a programmer and a tuner to Stillen for a week, to fix the problems that Stillen couldn't.

Regardless, the issues are fixed. Taking jabs at Stillen's abilities isn't really fair, when the finished product works well. Everyone's beta version of any product has problems. Yes, they did release it to the public before it was ready, but there is a benefit to that too: Widescale implementation increases the number of people that report problems to you, rather than just a few engineers. In turn, that accelerates your product delevopment. Having people like me on the forum bitching about how their supercharger didn't work right lit a fire under them to get it fixed, pronto. And they did..... if you call 4 weeks 'pronto'. :-)
