So see if this is correct...
Stratified Flash tune = canned tuned for a best guess at your car and the mods you have
Custom map = obviously just that? Completely custom to your car
Is that right?
I had a full custom map done on the dyno on my last motorcycle...money well spent.
Also, how does the Stratified modified Cobb traction control work in conjunction with the factory traction control/stability control settings and the use of the factory switch on the car? I've been trying to read and let it all soak in, but still working on this one.
Flash tune isn't a canned tune. A Cobb OTS map is a canned tune. When you purchase a flash tune from a company such as Stratified, they send you a form to fill out so that they know the mods that you have, and they will send you a customized flash tune. You can also get a revision made to it which will help even more. You send them a log and they will make the changes needed.
Custom map would be going whole hog and getting everything looked at. Flash tune will get you 95% of your potential, and a custom tune will get you 99-100%. It is just a question whether the extra $350-400 is worth 5%?
The Cobb and Stratified traction control does NOT work in conjunction with the factory traction control. You need to shut the factory traction control off in order to use the Cobb/Stratified TC.
The factory TC uses brakes, which makes the car feel like it falls on its face when TC intervenes. The Cobb/Stratified TC uses spark advance to limit power, which helps gain traction. So the car will still be accelerating, but wheel spin will be gone.
The cool thing that Stratified does is gives you TC settings from 1-8. 1 being the most intrusive, to 8 being all the way off. They have their recommended setting which is 4 and allows 15-20% tire slippage (which is the most efficient for gaining speed). In the tests that I have seen, they claim your 30-50mph time can be reduced by almost 2 seconds depending on the mods that you have.
