Piston Slap: MAP-ping Engine Load

TTAC regular David Holzman writes:

When my scan gauge says my engine is under 99% load, and I’ve only pushed the gas pedal about halfway down, does that mean, as I suspect, that I can floor it and I’m not going to get more than a drop more power out of it?

And, in a modern car (’08 Civic, stick), will the computer control prevent me from wasting gas by pushing the gas pedal beyond the point where I’ve reached 99% load?

  • Eng_alvarado90 This is not something I'd take in a Cadillac but feels about right in a mid-sized pickup. Again if 8t works on the 1500s why not in the Colorado? No bot whatsoever, either you haven't logged in lately or have no clue

  • FreedMike I’d like to say I’m outraged and won’t buy anything from GM, but aside from a Stingray or a CT5 V Blackwing, they don’t make a damn thing I want anyway.

  • SCE to AUX Hyundai still gives 3 years of Bluelink for free, then it's $99/year after that. I like it, and I pay for it.I agree that GM is just finding a way to raise prices, but what happens after 3 years - does OnStar disappear?This isn't different from other moves by mfrs. For instance, many drop the FWD option and standardize on AWD, while raising prices $1500. Few people complain about that.
