Shift light on an AT7?

wstar

It's unlikely there's any simple fix (esp from the dealer) to give you a 7AT upshift indicator on the stock dashboard. Probably your best bet would be to ask UpRev to include the feature in their custom rom (seems within reason of what they can do, sorta), but even that might be a stretch to get enough interest. It would be far easier to just install an aftermarket shift-light solution.

On that topic, I've been thinking about this subject a lot lately, and I'd really like a more advanced shift light to really help on the track. I'm thinking more like an RPM gauge layout with colored regions to help make both up- and down- shift decisions.

For example (totally made up numbers here): Suppose your best power band, where you want to be, is from 3.5K to 7K. Based on gearing, if you're in 3rd you don't want to upshift to 4th before 6.3K or you'll fall too low, and you don't want to downshift to 2nd when you're any higher than 5K or you'll be too high in the range to have any useful room left. Those numbers (6.3K and 5K) will vary by what gear you're in. If you had some software looking at OBD-II data, it could look at RPM + speed, and with gear ratio settings from you, inferred current gear, and knows whether you're currently accelerating or decelerating based on rising/falling RPMs.

Based on that, you could make an intelligent widget that gave you an RPM gauge that gave much more insightful indicators for when you're in useful upshift and downshift ranges as appropriate...
