recalibrate

[gijoe]

I'm putting 20's on my 01 ls. Tire size is 245/35, now my question is does many one know if you can recalibrated the speedo. I used to own a mustang and Ford Motorsports sells the equipment to do it. So if anyone can help me that would be great. Thanks in advance

the only tool for now is the SCT XCalibrator - www.sctflash.com

Torrie from www.fordpartsnetwork.com has been doing alot of LSes.
Our best tune is getting about 19rwhp and firmer shifts.

Shoot him an e-mail - he can get the ball rolling for you.

Does firming up the shifting help in racing?
Which gears and how much should I adjust the Xcal?

I also noticed that the short term fuel trim at WOT in the factory tune is @ 18.5 while Torrie's tunes top out at 13.25. In order to keep from pinging at WOT I had to increase the fuel air mixture.
Is this done on purpose?
Is there any advantage to running lean as long as there is no detination?

Lean is mean, but if you miss, Boom! This is particularly true with blowers and turbos... hint hint...

Factory, I believe they did what was called fuel dumping, which ate gas, but it kept combustion temps down and believe it or not reduced some emmisions. More fuel meant it was rich and ran cooler. Seems to me that's a pretty lousy and expensive for the owner way to make clean air cleaner, and it beats on the cats pretty good too.

I haven't done any actual track times since adding the shifting firmness to my tunes - it would make sense that it would be quicker since you spend less time hunting between shifts. It is mainly done for driving 'feel'.

Since Torrie is a 'tuner' I can only assume that the combination of trim and advance is the best thing he can do for more power - but certainly I am no expert on it.

I've been verry happy with the tunes Torrie gave me and his service was second to none.
That one just needed a little fine tunning for my vehicle.
I was just trying to understand the reasoning behind his fuel settings.
It sounds like leaner gives a bigger bang.
Kind of like an empty gas can will explode while a full one won't.

Someone should shoot Torrie an e-mail and post his answer here *wink*
