Nothing validates design failure of a car more than aftermarket offerings aimed at increasing its performance. Due to its bullshit off the +General Motors shelf engineering practiced by +Tadge Juechter and his team of Corvette merry men, the abortions called C7 Stingray and Z06 ended up with alleged fuel economy measures that extend beyond the typical skip shift solenoid in the manual transmission.
This time around, the skip shift is in the company of two other inventions, one called Active Fuel Management and the other, half ass variable valve timing-both directly lifted off GM corporate cousins, pick up trucks and SUV's. As already mentioned many times on this blog, these inventions are as unreliable as they could be (very well documented problems with truck and SUV GM turds from the last few years). Although these measures can make sense in pick up trucks (you cannot make a pick up truck sufficiently aerodynamic and GM is way too lazy to take any weight reducing measures Ford style), they are totally counterproductive in cars advertised as high performance vehicles (the latest Corvette cannot be called a sports car any longer).
AFM not only hampers performance of the engine and decreases its already questionable reliability but it also adds weight due to its hefty hardware and STEEL torque tube needed to mute the excessive vibrations/
Performance wise, the RPM range becomes even more limited than due to the direct injection alone. There are problems with activators failing due to the excessive heat build up and long term problems related to consequences of running both LT1 and LT4 engines in four cylinder mode.
These problems were well documented on Corvette C6R and its failure during LeMans racing. Long and behold, Tadge Juechter refused to get the hint and AFM is a permanent fixture on the newest generation of Corvette.
As usual, the aftermarket is there to cash in on design fuck up and of course, the schmucks who buy these Stingray and Z06 turds are there, anxiously waiting to pay pretty serious money to have this fine AFM technology removed from their cars, paying more for less as usual. Never mind there is a problem with their warranty going out of the window and very likely issues with emissions compliance, Corvette sheep is there to open their wallets and as usual, validate the failure of the original design.
The irony of the AFM removal "upgrade"? The steel torque tube is still there, adding weight and serving no purpose whatsoever, except for complicating clutch replacements and causing engine failures.
To aftermarket's credit, the AFM delete upgrade covers all angles of extra profits opportunities, right down to the block off plates, offered to make this upgrade more legitimate?
The real question here is: since the cost of this rather extensive deletion exceeds the possible fuel economy savings (assuming there are any to begin with and this is a very doubtful part), why cannot Juechter man up and start offering AFM and VVT delete as factory option? While at it, why not combine this option with aluminum or carbon fiber Stingray torque tube option as well?
To see the Corvette numbnuts paying up for removal of this junk is pretty funny but what is exactly stopping GM from following in the aftermarket footsteps? Too lazy or too stupid? Maybe these turds would last an extra lap on the track this way? Hmmm...
