You can always start over, never seen someone just totally mess their car up.

Yes it's quite easy, plug it in the obd2 port and follow the directions

Unless he wipes his tune and returns to stock. Those cams won't be happy at all.

Yea that's what I am worried about. I have the thing updating on my computer right now. It did say something about having to reformat and then flashed format complete. It didn't want to update the first time so I had to unplug from the computer and start the update again. Hope I didn't reset everything.

If I just plug it in to change the gear ratio and don't mess with anything else, it won't reset what I don't select right?

Yeah. Then reinstall the tune.

Well I'm not sure what tune is on here to start with so that might be a problem.

I haven't used one before but I have read about them in car forums. I do believe there is a option to back up your current tune before you start changing parameters.

That's probably gonna be an issue.

Unless I can check the specs when I plug it in? It did say backing up system when I started this updating process.

I would look it up on line to be sure

I'm not really seeing a spot to do that?

On the home screen on the computer I have check for updates, load custom tune, transfer file to device, update firmware, display device setting and serial number (this one?), and get stock file from device.

Is it plugged into the car? Or home computer?

I would Google how to change the rear end ratio in your tune.

Old story retold often. Only mentioning here again because you asked [for those who get bored at story recycling]. Buddy had one, bought it in Manhattan over internet.

Great deal, amazing deal. A 2yo floor model that he got for $25K with 12 mi on the odo

We drove it straight home from the showroom to St. Louis to cover the break-in. Took it to the Lotus dealership for tune-up and break-in cert the next week.

Wonder how many cars go through entire break-in within the rules specs, yet with almost no stop-and-go city traffic mileage whatsoever.

Flipping a Saturn with a bad head gasket. Took me a week to get all the parts off (31 steps) but just got it off today. I haven't done anything like this since I was a kid. I would never had the patience in my younger days. Actually enjoying it.

Sure hope it works...)

It's plugged into the computer. I am updating it. However, it was updating and froze and even though it said don't unplug, I had to in order to restart. I'm worried that unplugging when it said not to made it reformat as that's what the screen showed.

Now it's flying through the 3000 updates it needs on the computer though. Just wondering if I can check the current tune I have on here.

Once I get it running I know how to change the gear ratio based on what I have googled. I just want to make sure when I select one specific feature, my other tunes won't be changed as well.
