Fuel Economy

[mkrup]

Only if you're annoyed by the dash message.

I mean, it's more annoying than just a dash message... it will force you into 4th if you're not paying attention, and my experience was always that it ended up lugging like hell after it did (no idea how it's actually supposed to help with emissions/fuel economy, but I digress...), but it is relatively easy to avoid once you get used to it.

The only M6 I've driven had the eliminator installed. So I haven't experienced this. But how does it force you to 4th? Does it physically lock out 2 and 3? I always thought it was just the dash notification.

Not in my experience in a 2018 ZL1 1LE.

I mean, I haven't driven a car with it since the C6 so maybe they changed it, but my experience was that yes, it will physically lock you out of 2nd and 3rd if you shift while the dash light is on. You can dump it into neutral and basically double clutch to override it, but otherwise it's going to send you to 4th come hell or high water.

What RPM were you shifting at? In normal street driving, I shift ~ 4,000 RPMs.

Thanks for all the replies - this is interesting. I have read that it's only in effect with the engine warmed up, between certain (low) speeds and at low throttle openings. I test drove a 2019 ZL1 manual to get some experience with the drivetrain, and noticed the dash message but was able to shift into second anyway. I assumed the prior owner had installed the eliminator, but maybe not? This was definitely at lower RPMs than 4k.

FWIW, I tried shifting 1st to 4th at ~20mph just to see what happened - with the mountain of torque there was zero lug, just 'regular' acceleration.

It was probably below that. Would only happen during slow driving, usually in congested areas, which is what made it even more annoying--I didn't have the revs to sustain 4th, and would have to immediately downshift anyway. Try it when you're stuck in traffic and want to get out of 1st at like 2,500-3,500 and cruise in 2nd, but surprise you're in 4th and on the verge of stalling.

I would think that they would not want to do this with there last Manual masterpiece... but maybe @Mirza Grebovic can shed some light here?

 

[poor-sha]

At least on the C7 it only kicked in if you were very light on the throttle. Just give it more gas and it'll won't try to skip shift. I never had a problem with it.

@Mirza Grebovic helped us out with a response to this one already:

Who here will be getting the carbon fiber packages?

Thank you for this @Mirza Grebovic. Answers a lot of questions we've had Any reason the CT4 BW didn't get at least the rear camera mirror? Was looking forward to it coming from a 2016 CTS-V and seeing it on lower end Buicks but not a 60k Cadillac is a bummer Again a choice to keep the segments...

Thanks @treddi. Being a little slow, I had to scan it 3 times to find it so here's the direct quote:

"Skip shift is not on any of these cars per the reasons you have noted (we do listen!)."

Thanks I missed it 4-5 times too
