Received the UltraGauge in yesterday's mail. (Ordered Thursday, received Monday.) Printed out the manual (it's on the company's web site and is not shipped with the unit), and read it. Instructions seem sketchy when you read them, but are quite adequate as you use them to configure the unit.
There is a procedure that you go through to get the $9.00 rebate that is pretty obnoxious. The unit will produce a string of alpha-numeric codes, and you have to copy them down, and then type them in without error to a form on the company's web site. Then you print out that form and sign it, print out the company's 2 page Safety And Disclosure form and initial and sign it, scan those two documents along with the packing slip that came with the unit, and then e-mail the lot to the company. Seven weeks later you presumably receive a rebate check for $9. I think this is a data gathering tool for the company, as you must identify your vehicle by make, model, year, engine, transmission, and date of manufacture.
Configuring the unit to show the gauge readouts you want the way you want them (there are umpteen gauges and you can configure the unit to show them on any of 8 pages that the unit displays) takes a little time and patience, but it's pretty much a one-time deal. Once you've got it the way you want it, you're done. I'm not quite done with that, so I'll wait to provide user impressions until I've got it all set up and have driven it.
Still don't know if the Raptor shuts down the injectors upon deceleration to save gas. If anyone knows the answer to that question, please post here. I seem to recall reading something like that in the ad hype, but that was several years ago. Thanks!
