Yeah, so you can't use two chips at the same time if that's the question. What chip does KB use for their kit? Is it possible that the current chip can be modified for speedo modification? Speedcal for the fix?
I'm not sure what I'm going to do. Speedcal works great for the 5-speeds or older auto's but it doesn't show an application for a 1999 and up auto. Diablosport says my ECU has to be returned to a factory tune for me to program the gear ratio. My only option now is to send back my chip to KB for a new tune. That means my car will be down for x amount of days.
