Nope. Take your time, install with care, and rock and roll.

Pretty easy buddy. Take your time, don't drop screws when you're removing the cowl and everything. Besides that , just follow instructions and it's a walk in the park. I've done it a couple of times (I used to have a JB4 for gauge hijacking)...

Oh, and install the DCIs once you remove the cowl... it makes super easy

Im just a little nervous pulling the ecu apart i guess. Once i have done it a couple of times im sure it will be second nature.

Good idea on the DCI install thanks.

Same here but It's not as big of a deal. Make sure to let the car sleep. Plus you won't be taking the ECU apart you will only be taking of the connectors

^what he said. its such a cake install. Make sure u run the USB cable in the first time, my lazy ass has yet to do it after putting JB4 in. I'm going to go in there and get everything done, since I got DCI, spark plugs, now im gonna reopen everything up. AHH so lazy lol

When i first go into the settings menu, is the actual map selection shown on the speedo or rev counter? Going to run it on map 5 so i assume set the rev counter to 5 then down button to store, is that correct?
