i see...so what would be the reasoning behind switching the cam on the two models? i dont think there is any price difference between the two cams. I do know there is a weight difference in the two cars, did this have anything to do with the power assignment difference? Will an ETC out accelerate an ESC of the same year even though it has 25 more hp but weighs (i believe) 400 or so pounds more?
If you are asking if YOU can swap cams, the answer is no. The two cars also use different final drive ratios in conjuntion with the different engines. Likewise different PCMs.
Theoreticaly in a race the ESC (more low end torque) would lead off the line. Later, as the ETCs higher HP kicked in, it would pull ahead.
That would make for an interesting quartermile drag race, a etc vs a esc, wonder if anybody has ever done it? Sure think the ETC would win by at least a quarter second or so.
I think the difference may be attributed to suspension components (Continuously Variable Road Sensing Suspension, Stabilitrak) and possibly the memory kit, rainsense wipers, etc.
Performance-wise, I opine that highway speeds are where it's at. The ETC stands for touring which would coincide with its more responsive performance at 70-80 MPH and higher.
At those speeds the engine works at higher RPMs, closer to the power band upon WOT.
The internal gearing in the transmission is the same for all forward gears and reverse. The only difference in the the final drive ratio, and programming.
When I pointed out the difference was the CVRSS and Stabilitrak, I was referring to the 29 lb. discrepancy between the weight of both cars.
Hey danbuc, could you please chime-in on my "knock" post? I have some more clues, hopefully. Also have some warranty concerns, that you may have experience with.
What now?...I forgot who I was replying too. :hmm:
