So a little retarding of timing at light throttle below 1800 rpm aggravates you ?
I can’t even imagine driving around at 2100+ rpm constantly as a daily driver. To each his own though.
The issue isn’t so much the overly retarded timing at 1500 rpm and .35 load. The issue is that if you floor it in that state, then the car is a dog because the spark recovery rate is sloooow and doesn't reset until you back out of it. You wind up at 10 deg timing at wot.
Please explain.
These engines were primarily intended for the f-150, specifically designed to be lugged around reliably and efficiently on 87 octane towing a trailer.
That makes zero sense. you floor it from 1500 rpm, it kicks down. You get all the sauce. even in my manual from 1st I can punch it from that RPM and it's not just gonna give me 10 degree @ WOT.
Downshift.
Great for the f-150. His year coyote is all kinds of different compared to the same year F-150.
What can I say….I’ve logged this phenomenon myself on 3 different cars. If you’re already in first then there is no downshifting. Secondly, the knock retard sticks around longer than you think and may not start over at 0 when go wot and downshift.
Already in first gear.
None of which will cause “problems” when lugging. These engines are designed to lug around AND run wot.
No, I can watch the KR add timing @ WOT all the way to redline.
I can purposely lug the engine & watch the KR kill all kinds of timing.
And if you're in 4th @ 1500 rpm, downshift. Automatics do it for you.
there's no point to flooring the throttle at anything less than 3000 RPM. you're missing out HUGE not spinning the engine. This isn't some crappy-ass pre-'73 v8 engine which can't get out of it's own way.
Of course it can. But the rate at which it adds is either slow or normal. If you've pulled 15 deg of timing due to false knock at 1500 rpm then floor it, you're stuck in the normal rate or advance and you're at a 15 deg deficit to start with. I caught a good log that shows this I'll post momentarily.
So you have the same problem then.
The issue doesn't happen in 4th gear. In almost every case it's in 1st gear pulling away from a dead stop at a normal pace.
You don't even have to floor it below 3000 for this issue to hurt you. The issue happens to happen at 1000-2000 rpm, but if you floor it within the next 10-20 seconds the timing is still overly retarded and will kill your WOT performance.
It's a good problem to have. Wouldn't want it to ADD timing while lugging around. Tends to hurt things.
Well maybe it's an automatic trans thing. Certainly don't see that with a manual trans.
Again, we're talking .3-.4 load not .7 or .9. I'm not sure I would call that "lugging". .3-.4 load and 1500 rpm is right smack where these cars cruise at 65-75 mph.
My friend's car does this with an M6 as well. KR comes in <5 mph in 1st and if goes WOT then it's a slug.
Then it shouldn't be pulling anything
I'd show you my logs but you don't use CMR software. Doesn't crossover well with what you're use too.
Yes exactly. Sounds like we’re on the same page finally.
