That is not accurate unless the tuner has locked of the timing multiplier, which would be stupid, otherwise it should try to advance timing given the higher octane level based off of other variables. The ECUs in these are fairly advanced, especially in the 18+. If you want to understand it...
Some might not want to spend $600+ for an axle back just to get more sound without the drone. Those axle backs do have Helmholtz resonators but they are usually tuned primarily for running their entire exhaust system so there will always be a little more on the table. I would agree that it...
This forum needs more info like this on here. Really if you want a loud, non-muffler exhaust that isn't frequency tuned, without drone then Helmholtz resonators are the way to go. The only cons to them is slight increase in weight, a small reduction in volume under the drone frequency, and...
One car, the GTR, nothing "fragile" about that GR6 trans! Granted it will need upgraded clutches after adding a few 100+ lbft of torque and launching on a normal basis. Your statement is not entirely false per-say because there are some examples of very terrible production DCTs out there from...
Most OEMs do not use FF sensors anymore as they are terribly unreliable and not very cost effective. Most now use an inference strategy utilizing the O2 sensors, the fuel trim algorithms, and set "desired" AFR algorithms to determine the alcohol percentage. I can only assume that most tuners...
@Condor1970 I am in Bremerton so maybe we can meet up sometime and compare the sounds, cause my '18 definitely has the tick as did my '16. It did have the rattle but that has disappeared since I brought it in for its first oil change and asked for it to be looked at.
I had the oil changed to...
Sorry I must have misread this:
That is the post I was referring to. Either way I will be definitely looking into this as I am also curious as to why it was not continued on the later revisions of the coyote when it was a TSB...very odd of Ford. However, your bean counter explanation is...
@Condor1970 while this is a very interesting find, your explanation of how the noise the tensioner is silencing is "piston slap" and how "piston slap" is incurred in this modern engine is absolutely absurd. No amount of factory forward auxiliary pressure will out of round that many crank...
Even in manual mode you'll want ths shift speed quickened because it is still desired torque or tps conditioned even in track mode. In other words it doesn't shift fast and direct until you reach a certain threshold. It is the one thing that pisses me of with the factory 10r80 trans tune. I...
Two things about why this theory isn't sound.
1.) These use hypereutectic pistons that match bore expansion properly so that piston slap is nearly impossible without showing major signs of defect such as mass oil consumption and loss of performance. In other words, piston slap with this type...
Stock there is no rev limiter per say, the scheme is to close the throttle to limit flow, thus limiting the engines ability to rev any higher. There are maps to cut fuel or spark IF given parameters are met, which is very unlikely on stock tune.
That schemes purpose is to help combat...
Honestly if there is that big of a delay then you could be low on trans fluid or there might be something wrong with your valve body because the shift between P,N,D are all manual hydraulic inputs.
No problem, I am still learning more about this GEN 3 as well! I think a lot of the ticks are coming from the OEMs oil weight being too low, but that is just my suspicion for now.
My biggest experience with nikasil bores is with GTRs and I guess not I understand why those engines have there...
No tuner should tell you that they can't control or change the shifting, in any facet, for "D" or "S" mode in the S550. The "engine breaking" that you were referring to is nothing more than the downshift maps being set too high for a given Output Shaft Speed (OSS). When tuning the factory ECU...
Yeah I have to agree that you have an electrical gremlin somewhere as most of your problems seem to suggest intermittent grounding issues. As for the Piston slap... most people with 2018s that are posting that they have or had piston slap are just plain uninformed. These engines use...
