I just havent ever done one so I didnt know the specifics, I just knew the purpose/reason behind it.

3 runs with no tuning at a shop around here is like $65. I think it allocates you like an hour and 1 technician. You can do minor things to your car in between, but that's it.

Hmm, ok. That sounds reasonable right? :ugh2:

Just called another shop who has a 4WD dyno and they charge $75 for 3 runs regardless of 2WD/4WD.

EDIT: hahaha just called Jotech and they said $85 or $100 with wideband

I guess I have to scavenge the west side to find a dyno shop... :ugh2:

Automotive Diagnostic Specialties - Chandler, AZ - Auto Repair, A/C, Brakes, Emissions, Computer Diagnostics, Tune Ups, Diesel Repair, Alignments
Dyno-Comp - Scottsdale, Arizona Premier Automotive Tuning | Luxury and Sports Automotive | Accessories | Performance Components

LoL Both of those are on the East side of Phoenix! I need the WEST side Vipor! hahaha

I don't know AZ jeez. I surprised there's even 1 at all in that damned desert :mad:

You two are giving me a headache. Chris, go to this url, punch in your zip code. Dynojet Automotive Dyno Centers

Me too lol. hahaha

:icon18::roflpuke2: You're a trip. :tup:

simma!

Here you go Sam

You can definately see the top end gain. :tup:

Wow, I'm surprised to see how the TQ plummets after 5k rpm.

yeah most TQ "curves" on the VQ's are pretty flat....

What can we do to help bring it back to vertical?

You don't want it vertical, lol. You want it horizontal. (Maybe that's what you meant.) But seriously, I'm wondering if it has something to do with the AT. I mean, considering how flat mine looks (which is 6MT).

You don't want it going up? I thought more = better? Or is that just for HP?

You want it to go up as early as possible to its peak level, then stay there. What that translates into is a car that pulls early and continues to pull all the way to redline. If you had a curve that went upwards, it would mean that the car only pulls as the revs get high (think Honda VTEC). And I don't think you'd want that with this car as people already complain about how there's a lack of grunt below 3k rpm.

I found wstar's dyno sheet (also 7AT). It's flat for his 7AT as well.

OH ok. I thought you wanted it to 'keep' pulling, so going up on the scale. See like I said, I'm pretty low on knowlege of the science of dynos lol I just know higher numbers = good (minus practicality)

Right. A flat torque curve means that it keeps pulling. A torque curve that goes up means that as rpms build, it pulls at a higher rate. You'd see that with many turbo apps -- as the turbo spools up, the torque increases, but prior to the spool-up there's not much torque (aka turbo lag). Now, what concerns me about Pablo's curve is that, based on how the curve drops off at 5k, it means that as his rpms climb from 5-7.5k, his car is actually decreasing its rate of pull.

Is that a 7AT problem? Or something specific to his runs? I hope all 7ATs arent like that... That would piss me off. lol

You Smoke a CRX to see him putt putt putt past you just before the 1/4 mile lol

Well that's why I posted wstar's dyno sheet a couple of posts above. Did you miss that? lol

I saw it, but i didnt remember it until after I posted mine.. and I'm too lazy right now to ninja edit... Need to eat, strength waining... :icon14:

I had the same question and the tuner came back to me today and pointed out that the scales are different between TQ and HP - duh
He sent me a dynojet format and it looks like what you would expect

That's still a LOT of fall off after the 5250 (crossover on a NA) mark.

Did the A/F go back up to 13 at that point or something?

Actually, I think it looks right. It just looks a little exaggerated due to the scale. The y-axis is in 10 lb-ft increments, so even relatively minor changes will look a little bigger. Also, compare his graph with wstar's. Notice that the y-axis on wstar's graph is in increments of 40 lb-ft. And also notice that both curves end at 200 lb-ft @ 7500 rpm. In fact, if you look at 5k rpm, Pablo is making more tq (probably due to his tune).

per 500rpm from 5000 the first drops 5, 10, 5, 15, 15 - (35ft/lbs by 7000, 50 by 7500)

per 500rpm from 5000 the second drops <5, ~5, ~0, ~5, ~25 - (<15ft/lbs by 7000, ~40 by 7500)

"~" means "approximately" by the by

I know what ~ means! (And it's called a tilde.) :p Yeah I'm not saying they're identical. Pablo's curve still isn't as flat as I'd expect it. I'm just saying it's not as bad as it might initially look is all.

A lot of people are confused by that symbol for some reason, just makin sure :tup:

It just still seems to be a lot of fall-off percentage-wise.

I wonder if the type of dyno has anything to do with it. This was one of those funky hydraulic dynos, after all.

Looking amazing Pablo thanks for sharing :)
