Bob is very correct. In-fact it took practice to get it down. I have 400 runs on my frs. it took a good half a year to nail it every time. And still every now and then I miss it. Its doable and it takes a lot of brake modulation. You cant just hammer the brake 100 percent and gas. Toyota smart stop tech jumps in and shuts fuel down. its more of a 60 to 80 percent braking 100 percent gas. As soon as you feel the tires slip let the brake go. If you hold it you will spin the tires in one place then the backend starts to move. to much and you will be sideways

here is a thread on launching the FRS.

Your tune is about a 9% gain over stock. Using the raw number alone means very little due to the fact that all dyno's read differently. From what I have seen, yours reads much higher than most, if not all baseline dynos. Most of the stock numbers that I have seen are actually much closer to the 160-164 range.

If I used my % gain over baseline on your baseline (to simulate me running on your dyno under the same conditions), I would be hitting 204 (+18% peak) on pumpgas, and 215 (+24% peak) on E85.

Meanwhile, back at Dynostys heartbreaker dyno, my car came off with numbers very similar to your baseline. I still had the same % gains over the stock cars that ran that day, but the raw number went from a +40 hp gain over "stock" down to about a +30hp gain over stock.

As you've stated you have a mustang that's been "tweaked" to read like a Dynojet, but it might not be adjusted properly.

Can this be ported or used through OpenFlash?

As you say, all dynos read differently, and one should not compare numbers from one dyno to another. The stock and tuned runs above were run on the same dyno, the same day, withing minutes of each other. The actual HP and TQ gains are what we focused on, not percentages.

Now, if you talk about percentage gain, that number can be skewed because it is based on the raw numbers. If you look at going from 100hp to 110 hp, that is a 10hp gain, and 10% increase. Now, if you look at going from 200hp to 210hp, that is again a 10hp gain, but only a 5% gain. For 300hp -> 310hp, 10hp gain, 3.33% gain. For 50hp -> 60hp, again a 10hp gain, but a huge 20% gain.

So, you really can't use percentages gain, especially if comparing different dynos with different baseline numbers. Always use actual gains compared on the same dyno under the same or similar conditions.

I don't believe EcuTek ROM files can be ported or used through OpenFlash. The formats are not compatible.

I see. So although you can't port or use through OpenFlash, can you still gain the same results using OpenFlash over EcuTek? If that makes sense.

Sorry that doesn't make sense to me - percentage gain should be a great way to compare results. Install a dynojet and a maha dyno in the same garage. To simplify we'll look at peak numbers. One car. Run it on the dynojet, get repeatable baseline. Runi it on the maha, get repeatable baseline. Let's say the dynojet peak is 165 and the maha is 130. Strap on some mods, and run on dynojet, get a repeatable 189, +24 rwhp on the dynojet. You won't see +24 rwhp on the maha, you'll likely see 150 rwhp or +20 rwhp. On both it works out to +15%.

I do see what you're saying about comparing %gain between different mods on different dynos, but at that point it's all moot. Dynos are only good for comparisons on that dyno on that day. Everything else is, in reality, not comparable if you're at all concerned with accuracy.

Lastly I just want to say in general, comparing peak numbers is like comparing 0-60. It's just not a good way to compare cars. The average gain is much more important - and that said your increases all along the dyno curve look great for just a tune.

Hey, I understand what you are saying too. It all goes down the drain when comparing numbers from different dynos. And I agree, the gains across the entire RPM range are what is most important. And we tune to gain the widest power band possible, not just peak numbers. That's why it's important to show the before and after graphs to see the gains everywhere.

Thanks for the compliment and cheers!

Will you post the graph with a linear Y axis, (hp to ft lbs)?
I'm not knocking you, just dislike different scaling.
I don't see the point. (Please don't say its for clarification/resolution)

[s2d4]

The thread title is misleading,

It says stock, then claim some numbers.

Look inside, it says filter and "muffler delete", on some extremely optimistic dyno scaling that reads over 170hp for a stock car.

[Ammonia]

My car dyno'd for 151whp on a heartbreaking mustang dyno. Can you un-adjust your mustang to read like its supposed to? I think thats whats having people be a little more skeptical or non-understanding.

[R.S-HawK]

You had my curiosity. But now you have my attention.

I'm located down in Tampa, FR-S auto with 17K miles. Stock with drop-in K&N. Only potentially looking to replace the stock tyres and the intake tube.

Intrested in a quote.

We only have the dyno graphs that are posted. We hadn't realized until after the fact that it was scaled so far out.

The scaling we have shows the full resolution of the map, so it's drawn out a lot more, show "more" of the graph. The graph, when scaled the other way, would actually look more impressive, as far as the lines rising faster, so the pics we have are actually a dis-advantage that way - not a trick to help us.

If you read through the entire post we proved that the filter and delete made no difference in power on the Dyno. We literally tested them back-to-back on the dyno to make sure there was no noticeable difference. The customer wanted to leave the muffler delete on for the videos and subsequent driving portion of the video after so we obviously wanted to test it, and make note of it, so there wasn't a glaringly obvious modification we didn't address.

We have also addressed, in detail, the dyno numbers and why the scaling makes no difference on our gains over stock. Gains over stock are what matters guys, NOT a final number.

We have been very transparent on our findings and numbers.

It's not our Dyno. It's a shop right down the street from us and they have it setup just how they want it for their purposes, and they do a lot of their own tuning on it. So it's not our call, if it was we would change it.

We are planning on dyno-ing the car again on another dyno just to get another set of numbers.

Again, it's the GAIN that matters and not the actual HP number, But it's clear it's a stumbling point for some people, so we'll oblige.
