Anyone that has been running KPro or FlashPro is probably familiar with “eTuning”, or tuning done through email. If you are not familiar with the concept it is pretty simple. You give an “eTuner” your list of mods, he generates a basemap and emails it to you. You take datalogs during idle, partial throttle driving, and full throttle driving and email those datalogs to the tuner. Adjustments are made to the map and emailed between the customer and the tuner until the set-up is optimized.

Since we have decided to start eTuning, I decided that a write-up was needed to clarify when an eTune or Dyno Tune is needed and the pros/cons of eTuning.

E-Tuning Pros:

• Inexpensive compared to a full Dyno Tune
• No traveling needed as with dyno appointment
• No waiting for dyno/tuning appointment
• Allows quality tuning to be performed from Evans Tuning for customers that are not within traveling distances (International and non-Northeast locations)

E-Tuning Cons:

• Cannot fully tune VTC (variable camshaft movement) as accurately as on a dyno
• Cannot fully tune ignition timing applications as with a dyno (cannot get the most power safely)
• Extreme set-ups with nitrous, built engines, extremely large camshafts, high boost turbocharged/supercharged, etc. cannot be tuned safely without the use of a dyno

You might be asking yourself, “So how do I know if I should choose an eTune or Dyno Tune?”. Well the answer is pretty simple. If you have a naturally aspirated set-up that has a stock engine, stock cams with intake, header, exhaust, and other common modifications an eTune will get your car within about 80% of its full potential. If you have a common supercharger kit like the Jackson Racing or CT Engineering with intake, header, and exhaust modifications an eTune will get your car within about 80% of its full potential. If you have a Greddy kit, or Full Race kit on a low boost application an eTune will get you within about 80% of its full potential. Heavily modified cars with built engines, large camshafts, large injectors, high boost (more than 10 psi), or nitrous applications NEED to be Dyno Tuned in order to get the best possible results. An eTune is possible, but we do not want to take any risks with your car.

I have been extremely busy with FlashPro tuning in the past few months, and have a very large database of tuned basemaps to start and eTune from. This means that you will have a VERY good starting point for the eTune to be performed. I am very excited to be able to offer eTuning to customers that would otherwise not be able to have me tune their cars (International, West Coast, Midwest, South, etc). Since traveling to tune cars is just not an option for me anymore, eTuning is going to open a whole new door for Evans Tuning in the tuning marketplace.
