Well I got my Bama tuner yesterday woohoo
I plugged it in set the 87 performance tune did the key on (dont start) key off thing when setting the tunes. Turn it on with a huge grin on my face and no noticable changes.... damn (EST: 12 miles HWY, 15 miles city)
I don't have 91 fuel in the tank so I didn't risk running the 91 performance tune.
At the end of my day I decided to test the rev limiter. It still limits at 3K.
I called Doug, he seemed suprised that I experienced no change, but enouraged me to try the 91 octane tune to notice more significant changes. He told me he doesn't remember if the Ranger 4.0 tunes remove the rev limiter, but from my forum searching it appears the limiter is removed. He did however assure me that the steps I replayed back to him meant the tune was sucessfully installed.
Oh yeah, when I grab the computer codes it list one code that means the ECM is unfamiliar with my driving habits and is attempting to learn them.
Please help me figure out if the tune is even installed, I was looking forward to this tuner so much
