Pretty sure the 'after' numbers check out even if the baseline numbers could be questioned. In the vid I posted of the final run he's clearly in 4th and I'm fairly sure The car wouldn't have dynoed anywhere near 180 in 3rd or 4th untuned.

Also giving me comfort is that the numbers on my car seem pretty much bang in line with what I'm seeing from other before & after tunes by other tuners on other dynojets around the world on this forum. That I was standing right beside the dyno all day during the tuning helps and am very much enjoying the feel of the extra power on the road.

Am always happy to hear insights into the numbers though...to learn is why I share and I'm far from being a dynojet expert. Fire away!

I am just wary as when I get my BRZ next month, I myself am going to have to be visiting for a tune as there is no others in Dubai that I know of doing ECUtek RaceROM.

Just dont wanna get shafted and if you say you can defo feel an improvement, hopefully it was just a mistake in the typing.

I'm pretty sure it was just a mistake in the typing but I'd be happy to race a stock 86 or BRZ just to be certain.

In any case, nothing to hide here. The actual numbers compare well with others on this forum. Being skeptical is also a good thing. Many of the dyno graphs posted elsewhere on this forum are often cropped in such a way that they don't show anything at all besides the the actual dyno graph itself. AFRs are not always present. Full screen grabs are super rare. So are videos. Out of a given number of runs only certain ones are actually graphed and posted. Also keep in mind that anyone posting dyno runs will tend to be 'selective' in what they post to some point, for whatever reason. Cognitove bias and all that,

The truly objective, transparent and knowledgable among us who can spot the flaws are like gold. I'm neither of these, hence my approach is to simply chuck up everything I happen to have on my phone, for better or worse, for the LULZ. If something's out of place then good. Glad to have eyes on stuff. Happy to hear people chime in and whatever discussion comes out of it is a good thing IMO. Anything truly out of whack will get checked out and fixed.

Anyhooo, the OTD tune was definitely not a simple 5 minute flash of a canned tune. As far as I know OTD do all their ECUTek tunes for the 86/BRZ by themselves on their own dyno on their shop 86 (based on whatever base map ECUTek is providing to all of their distributors I would assume).

My experience was that 90% of the time between 10am and 4pm that day was spent doing nothing but pull after pull and looking at different parts of the very same single curve time and time again, making small changes to get it 'just right'. If they were out to shaft me they could have done a baseline run, flashed the car, done a few tweaks and power runs and had me out of there in a fraction of the time to work on other projects but they didn't - they took their time.

Sam at OTD is a certified ECUTek vendor (and HKS certified master tuner, as well as the loooong list of car builds) so yes, thanks to the ECUTek connection we get all the latest ECUTek RaceRom options like launch control, flat foot shifting and autoblip, per-gear rev limits etc. etc.

FWIW to be completely honest I would have *never* recommended or considered tuning a car locally in the UAE even 5 years ago. A friend of mine actually flew a guy in from Singapore to Dubai to Ecuflash tune our Evos back in 2007 and we ended up getting 20 Evos and Subies Ecuflash tuned by the same guy due to a) the huge level of interest in tuning here versus b) the general lack of faith in the standards of local tuning at the time. The quality of the tuning work here has progressed a LOT in terms of quality recently though. Shops here have tuning certifications now, shop dynos etc. Buyers here have a lot more awareness and many more choices. Good times.

I have huge respect for Visconti, FA20club.com and the other tuners on this forum but choosing between a remote tune which would take days or weeks to get right via email in the *best possible case* versus a local tune, which took one day's worth of time on a dyno (and is getting similar numbers) was a pretty straightforward decision.

Hope that helps

Quick update...done some real world testing.

Was a little confused about these dyno questions so arranged a meet in a secluded, private area with a fellow forumer who owns a stock 6M/T car here in order to do some runs to compare things - for science!


Quick rundown of the specs on both cars:

Mine: Stock intake, ECUTek tune, Remus catback, 18" OZ Ultraleggeras w/225/40/18 Continental Sport Contact 2s and a full tank of gas.

Fellow forumer's car: All stock, 1/8 tank of gas & 16 inch rims with the random skiny 16s we get here.



Outcome: Whatever we did - 3rd gear roll ons, 2+3+4 runs from a roll, etc. - the outcome was IDENTICAL acceleration; advantage to whoever started first.

So, either the tune makes no real difference in acceleration or if it does then whatever 'extra' there is from the tune is just enough to offset whatever minimal difference there is with the different wheels, tires & fuel.

Make of it what you will.


Thanks to the anonymous forumer who showed up for the test - great to meet you!

Hmm im not sure...Doing some acceleration runs stock vs tuning i was able to shave off about 0.5-0.7 secs from my 0-60's. Then again u did rolling starts but looking at your dynos u gained around 3-20hp and your wheels are also lighter than stock so in my head im thinking you should be faster. I was thinking of doing the same thing and comparing my car to a stock car.

Driver, weight, rolling resistance, etc.

Thanks for posting though. It will make a good discussion point.

[DarkSunrise]

At the very least though, it shows he didn't gain the +21 whp shown on the dyno. Differences in driver, weight, rolling resistance, tires/gearing, etc. shouldn't negate that large of a gain.

OP -- do you have the Remus exhaust that eliminates the presilencer/resonator?

[ill86]

Driver can make a lot of difference. Even in a straight line. Both manual trans?
One had a full tank of gas and 18" wheels. The other 1/8 tank and skinny tires on 16" wheels.

This is why I don't race on dynometers. :-). The conditions are not real world. Temps, airflow, etc come into play.

[DarkSunrise]

Yep agree. And as you said, it makes for an interesting discussion point.

Yep, I have the full on Remus system with the back box and unreaonated midpipe.

Agree that the dyno results are inconclusive. I'll be super watchful next time I go back to get it retuned (adding a filter and overpipe/front pipe at some point).

I have The Pocket Dyno app I can play around with to test how variables like fuel load and wheel weight affect acceleration but that's pretty inconclusive too (depends a lot on your launch, surface you're on & shifting technique).

Anyhow, I'm still enjoying the car a lot wih the tune.

[Travers]

Thanks for sharing your experiences. I met with Sam and Dave at OTD and they seem like great guys. I'll be in line for tuning/intake/exhaust soon too and now I know what I'll need to ask for before we take screenshots of the dyno output :-)

Hi Ultra,

Thank you for your thread. Very informative and helpful! Any chance we could meet in Dubai, perhaps with other 86 members? I've got a few queries that I am sure you could help with.

Your results are intriguing - I think the fact that you feel the difference while driving is a big step. I'm not as technical as I would like to be, but coming from my s2k, i think the car needs to 'breathe' better, if only to make the daily drivability better. In someways if an exhaust and tune has done this, you've gained a lot! While this car has potential, we all know we didn't buy it for its straight line speed.

I am pretty sure an intake and added overpipe will complete the feel.

PS- if your ordering any, there might be a few dubai members who would be interested as well

Looking forward to your results! Sam will treat you right!

Happy to meet up any time. I attend the local 86cult meets from time time as well.

And yeah, an over pipe + front pipe + intake is on the list.

[Navadv]

Sounds good. Any idea on when everyone is meeting next?
I'm particularly interested in hearing your Remus exhaust.

I should have realized earlier that Sam could do this.
Mind if I ask how much He charged for the tune?
