Is there a consistency with Dyno results on the Fn2's and different tuners/Dynos

Went for a remap/Tune yesterday but due to flashpro issues it never happened. The car in the first run pulled 203bhp. With a 2.5" exhaust and intake Mods I expected a little better.

The Tuner told me that it's a good healthy result and some Dyno results are slightly generous.

Booking back in for a few weeks time hopefully to get the tune sorted now flashpro have released a new software sorting the Fn2 connection issues.

I no BHP is pub talk and it's about how it drives and performs. But it's just seems around 10-15bhp lower than some are seeing from the likes of TDI's rollers and so on. Certainly not saying that others fix results just a curiosity in results so please don't take it he wrong way.

I don't have a print out of the first run as I will get it all on the Full tune Day next time.

EFI Parts is where I went and Chris There was brillaint. Tried everything to resolve the issue. And before the issue explained everything he had planned for the day.

Every dyno reads different to some degree or another. They're a tuning tool and can't really be compared to each other.

That's fair enough loxy. Just crazy how I can get 200 on one and 215 on another. Shorly all dynos should be fairly consistent.

I know conditions on the day and other things play there part.

Tolerances within the engine itself play a big part.. so stock engines are never one and the same due to the variability of the components in the engine. But all within their design tolerance. Which is why on standard car Vs standard car on the same rollers, the bhp and torque curves are never 100% truly the same, not is the max outputs.

Does the car feel better Spike regardless?
Didn't get tuned flashy due to flashpro issues. Only resolved it with last nights software update

Yeah I understand engine tolerances and one engine may vary in power to another.

But if I ran mine side by side on two different dynos they would make different results. And could potentially vary as much as 20bhp.

Sorry, yeah I did read that earlier, it's been a long day :laugh2:
Still, when you get it mapped you may be surprised

If you're not tuned yet I wouldn't be too worried about it. With only an intake and a 2.5in exhaust you've not *massively* altered the car over stock. Like Flashy says, once your car's mapped for the changes you may be surprised.

Yeah can't wait to get it tuned. I'm certainly not hunting for bhp as you said the Mods will only make slight improvements and notning drastic. But will make it more driveable once tuned.

It's just the consistency side that amazes me of Dyno results.

Consistency on dynos is rare as there are so many variables.

Different makes of dyno,
Climatic conditions,
Operator - they can easily amend and / or fudge the results.

Comparing different days on the same dyno isnt too useful, let alone different dynos.

If a specific dyno and operator tests lots of the same car then they will know what ballpark the bhp should be.

As you have seen TDI North do lots of K20 work, and so do Eurospec 2000. As a rough guide TDI North shows 10-15 bhp more than Eurospec for naturally aspirated K20s. Eurospec dyno has been called the heartbreaker, but essentially its a tuning tool and its the before and after tune which is important.

As an example I had an EP3 at 225 bhp with Eurospec. No changes and dynoed 239 bhp at AMD Essex. Sounds much more impressive but thats why comparisons are risky and complicated.

Talking about Eurospec. My car on there dyno was like 245 bhp. So not bad. They do help you a lot with good advise in detail on what to improve to get good gains. Good service. I'm going back there soon to get my charger fitted. So if your after some cams private message me. Should be selling my drag cams 2.2. Fitted September 2016 so not been used a lot. As I have to go back to stock cams

If I was you I would get your car remapped, now that you sorted your flash pro, then dyno it, and see what the outcome of that is first
