You're kidding right? Do you realize how many people have hooted on me for calling out the manufacturers on their claims? For only trusting independent objective empirical information from people with no financial interest?

What it amounts to is when the car was on the dyno, I saw room for improvement and basically fuel/air is the first place to start. That the Cobb does do only you really need to be knowledgeable in how basic tuning works and how their software works. It was free dyno time and the thing is not an arm n an leg. As mentioned, Handy Gadget.

Called Calvin whom does the Cobb tuning in Plano yesterday, they appear to be stand up people in every manner and so far have not made any outrageous claims to my knowledge. He and I both are completely in the dark as to why the car is pulling out timing in the midrange and told me to reset the ECU, drive the car and log what the timing is doing. If that didn't work, it was another dyno session to get a better handle on the car.

My impression is the ECU are strange birds to deal with for everyone.

Anyway.....This is what the Cobb currently does:

Fuel Tables
• Intake Calibration
o MAF A and B
• Base Fuel Schedule Modifier (Beta)
• Fuel Multiplier
• Injector Latency A and B
• Injector Latency Multiplier and Offset
• Injector Scalar A and B
• Primary Fuel (8 points)

Ignition Tables
• Ignition Hi Det
• Knock overlay Hi Det
• Knock overlay primary A and B
• Primary Ignition A and B
Limits
• Rev Limit - Fuel Cut (2)
• Rev Limit Throttle
• Rev Limit -Limp Home
• Speed limit A-C
• Speed Limit Hysteresis

Misc Tables
• Idle Table A-E

Throttle Tables
• Throttle 1-8

To be candid about half of it is Greek to me and I'm going to take the car/software to a couple of buddies whom tune full time for help.
