Announcing the two newest additions to LaSota Racing's Tuning Book Library!

The Coyote Cookbook for SCT Advantage software

and The Coyote Cookbook for HP Tuners software

Customer comment: "...that's the best $75 bucks I've ever spent. If you're going to spend $379 on a programmer, then $349 on the software, a guy would be a fool to not to spend a measly $75 bucks for this very detailed guide... This thing gives tips and explanations that very experienced programmers that I've spoken to have never even thought about. It's like having a direct line to the best of the best programmers to explain it all to you in the greatest of detail... Considering the cost of the hardware and the software from SCT, I can't believe that LaSota is willing to sell this level of guidance through the process of using it all so cheaply. I have performed MIRACLES with this 2001 Mustang GT 5.4 32V conversion car in a single day thanks to the insight provided by this guide."~Terry G.

The best option for tuning for most people is to tune their own vehicle. It is not brain surgery and once you 'get it' you will be forever free of dynotune costs. 99% of the tuners out there are average intelligence. Some people seem to perpetuate the myth that that tuning is a secret arcane art - it's not. On a mechanically sound car it's not too difficult. The packages are often cheaper than a lot of dynotunes but YOU keep control of your own car. We give a free base tune and emailed support as well and you'd get access to SCT's Pro Racer forum.

Zeitronix Widebands

We have used and evaluated all of the lower priced widebands available. We have compared many of them to high end widebands such as lab grade widebands. And the one wideband that  really stands out in accuracy and features is the Zeitronix. We compare Zeitronix widebands, on the dyno to lab grade widebands. all the time. And the agreement between the two is simply amazing for a wideband of this low cost. The available features are amazing as well. It will show simultaneously: Air to Fuel Ratio for gas: Lambda, REQUIRED for alcohol based fuels (i.e. all gas from the pump); RPMs for most cars without extra cost boxes; TPS percentage; MAF volts (or another 0-5v source) and lots more. With optional sensors, boost and EGT temps too. Ohio residents 7% sales tax will be added. CA Residents add 9% Sales Tax.

LaSota Racing Technologies is one of the first SCT Dealers in the country and the first in Ohio. When SCT needed experts to train new dealers to tune cars, they called on the experts at LaSota Racing to help with that task. LaSota Racing has been traveling and training new dealers since SCT started.

When SCT needed a book written for dealers, and Pro Racers, a book that would be the 'Bible' of tuning, they turned to the experts at LaSota Racing. We gathered information from all of SCT's staff experts, used our own tuning knowledge and wrote the book that is now in use by hundreds of SCT's dealers. And now we have come out with our own line of manuals, updated and much more comprehensive.

Let us use the expertise that SCT trusts on your ride!
