Torque dip removed with just a tune....
 

(ESPN 30 for 30 voice).

What if I told you, a shop has removed the torque dip on a bone stock car with just a tune....

I'd ask what's up with the AFR's.

Who is my new tuner?

(and crap - I was going to quit at 86 posts)

I'd say to show me a dyno. The TQ dip is still there. It's a little smaller, but that's far from fixed.

dip is still very much there, just doesn't seem like it since the dyno sheet starts at 3.5rpm.

I want to see the full Dyno too. They claim to have removed the dip....

I'd say don't be Visconti. Post the details instead of little vague teasers.

Who is they?

LOL! Good call.

Olympic Motorsports in South FL. Saw it on Facebook

They also built a turbo for our cars...

i'd say it has been move in the lower rpm range and on the stock one the dip is not that big

I want more details!!!

Check the dyno sheet you won't need any. lol

This. The graph looks smooth and less "dippy" because we're not seeing the dip in context of the entire powerband.

And yet one would think that I looked at it... Guess I missed it on the FIRST post.:lol:

While there still is a dip I think it is very small compared to the stock dip.

One could argue they are showing the dyno from 3.5k because that is where the dip starts to occur in the first place.

But then you can also counter argue that maybe the BIG dip has just been moved to the lower RPM"s which they so conveniently left off.

Need full dyno chart.

The dip usually starts around 3200 RPM, which isn't even on that graph. If there is a torque peak at 2500 RPM which then falls off, which it looks like it does in the graph, then it's still there.

I've seen dynos from other shops which look similar, the dip is lessened/shortened but it's still there. Especially the E85 dynos, what gas is this on?

at 160/128, i hope it's pump gas, otherwise, worst e85 tune ever.

The way they scaled the graph makes it look like bigger gains and less dip than it really is.

I'd say i accomplished the same thing a couple months ago with BRZedit on my car:

This was taken from my cam timing thread

That is just cam timing changes. I figured out latter that my stock comparison map actually has a few degrees more timing advance than a 100% stock map would with IAM at 1.0 (due to the way i re do the advance and base timing maps).

It's probably due to the car shifting on the barrel at the start of the pull don't take low rpm sheets too seriously on a RWD car.

Dip is still there. You see peak tq. Is around 3250ish. Dallas and climbs back up around 4000. I don't think its possible to remove the dip without new headers and a tune.

I'd say it's still there. A flat torque curve is alot to ask. Very nice curve nonetheless.

The reduced dip might due to extra smoothing correction of the plotting...

Also intriguing is the fact it keeps gaining power after 7k rpms and the torque doesn't dive at higher rpms.

The dip looks smaller because the plot is stretched horizontally people. No offense to the tuner, but the reduction they got is typical of any decent tune.

Yeah I don't see it. Unlike the dyno of my car. http://i.imgur.com/rPBwI8S.jpg

Yup I posted something like this earlier.....proposing that the engineers pulled timing or something.....based on some research I did, granted its not going to be the be all end all fix. But definitely progressing in the right direction.

My statement may have some truth to it after all.

ill stick with fa20club/visconti. they are the master tuners for a reason and if they still have it somewhat there then i call shenanigans

They put their tune upon my chip. When I dip you dip we dip.

I know threadjacking is typically frowned upon, but DAMN is that a nice dyno :O

No offense to anyone as one of those is my tuner obviously!! But this are words directly from another ECUTek tuner: "to become a master tuner, you just need to place a large order of tune kits, its nothing special". I honestly don't know if this is true or not but regardless, I wouldn't base how good or bad a tuner is based on the "master tuner" designation but more on lots of reviews of their work.

where'd the other thread go??

To further threadjack, how much does a tune usually cost to apply?

Depends who you buy it from but its usually

300$ - cable
300$ - license
300$ - tune

If you have a license and either have a cable or borrow a cable, its about 300$ give or take

Deleted; they were trying to sell tunes without being an official forum vendor, which is against the rules.

If I had to take a wild guess, I'd say he was banned pending vendor account payment :scared0016:

something tells me they weren't going to sell many tunes the way that thread was headed. :bellyroll:

"HEY! look at our awesome tune! It's peak run made 1.5HP over our stock run in this video!"

"It flattened the dip inside of the dip"
