Nice Wrap work Lance. Give us an update on what it does for the heat.

Thanx Dave!.....the only way that it came out that nice is because of the neat, inexpensive CV band crimper and bands I bought for the job.....my Rhino wrap job was harder only because of the type of bands I had to use on it....

I can already vouch for what the wrap does from the Rhino,,,,but I had gripped my hand on the #1 stock headpipe pictured towards the back and counted 1-1000, 2-1000....until I had to remove it....did the same thing at the same place with the wrapped pipe and it was over twice as long...a good indicator IMO....

Really nice work Lance!

clue me on what the Digytune Pro does.... I mean I know if helps optimize the performance...but how? what does this unit do?

The previous regular series of Digituners, like on my Rhino, will add fuel to counteract the better scavenging effects of the better free-flowing exaust system, bigger cams etc...that is what a fuel controller does...if you have a free-flowing exaust, you will want a fuel controller of sort to add more fuel to keep your AFR from becoming too lean=engine damage....

As explained to me: This is the very first of the "Pro" series in Digituners...it will add or subtract fuel......was used because of the Commander.....and if hooked up with a proper AFR meter, you can tie the two units together electrically (called closed loop) and then drive.....

So for explanation purposes,,,,the O2 sensor of the AFR meter will adjust the fuel controller in real-time mode for a premium AFR at all times, just like vehicles nowadays.....so it compensates for elevation, humidity etc. without the hassle of a laptop, monkeying with fuel maps etc.....it also is load-based where most fuel tuners are not, I believe I heard and it also has capability for around 2 hours of data logging.....play awhile, download thru the usb cable, look and print your AFR, throttle position, RPM graphs to study.....
