Hi all,

Had the day off today so thought i would give the take old girl for a dyno run. Ive had three runs done today. I must say what the fu$k is going on with my car.

As you guys know standard figure are 130bhp and 229 lbf.ft of torque.

Custom code remap is Phase One 175bhp and 280 lbf.ft

Run one in 4th was 160bhp and 135 lbt.ft WTF

Run 2,3 in 5th was 159.2 bhp and 228lbf.ft

Took back to the garage and he could not believe it and said that ain right. No fault codes in ECU. Cars running sweet otherwise just not delivering the power.

Custom code says they have never seen anything like it.

Any suggestions

Binding brakes?

Why were the runs done in 5th?

Seems like an awfully high gear

Everyone argues about roller results till they are blue in the face, but they can, and are VERY hit and miss. Does it go well on the road? If so, just drive it and enjoy it. If anything, the only part worth inspecting is the power curve on the graph.

Car goes really well. Just interested in what it was putting out. Ill post the power curves for you guys.

Custard code

I was under the understanding that dynos are normally done in 4th, as the is the closest to 1:1 ratio of gearbox/wheelspeed/magical pixie dust. Or something?

Yeah exactly what he said.

OR...

I did try and see you right when you were hunting round

for someone to map your car.

Sorry to hear you have had problems with it though mate.

Hope you get it sorted quickly. :yes:

Have you had the car on the same Dyno when it was standard?

Remember, it's a

However, normally dynos over-read (give more power), not under-read.

No standard dyno test. something is fishing. Why are people calling CC Poo? If they have no experience with them?

To me, it is generally quite unlikely a stage one (assume a generic stage 1) remap will be in excess of 160bhp, maybe 165. You'll be wanting a proper custom setup to achieve 170 or more and then you might be pushing the stock running gear a little hard, mainly the turbo.

Spot on. And paying double the cost of a unit 18 custom map for a generic map is crazy IMO

Mines got a custom code stage one generic map . . .and earlier this year on the rollers did 163bhp and 264ft/pound .so ur figures arnt a million miles away . .That was standard. . since its had a full exhaust n decat but not bin on the rollers since. . .hoping to get a front mount sorted soon and get a custom map to take it all into consideration. . .Suggestions?. . .haha

Having just monopolized Shark's dyno for the best part of two whole Saturdays I think I can safely say that a good dyno and operator is highly consistent and, in the case of the Bapro that Shark have, pretty accurate.

Ben took great pains to explain to me why 4th gear was the best compromise of run length and clutch abuse (3rd gear is kinder on the clutch but the run is shorter) and I don't think the car would pull if you floored the throttle at 1250rpm in 5th.

Depending on which engine code you have (ASZ or BLT) then 158bhp can be the high end of standard power output (my BLT engined Fabia was measured at 148bhp standard) so then it's all about the smoothness of the power and the length of the delivery, how smokey it is etc.

I think I'd be unhappy with less than 160bhp from a remap. If you're not happy ask for a reversion to standard and your money back.

Their agent, JBS, upset a lot of people in the VAG world and they went from being a top player to an also-ran very quickly.

Some claims that were made were pretty much just lies, people didn't get stuff they had paid for, engines literally melted etc.

The guy that did my remap is very disappointed to see me unhappy with this remap or shall I say the power curve print outs. Also I have found out that the guy that did the rolling road doesn't like the guy who did my remap...vice versa. Some politics involved and I feel like I have been caught up in the middle of things.

The guy who did the rolling road was trying to sell me one of his remaps. WTF. Said he could get mine up to 193bhp and 302 lbf.ft

Going back in next week and were going to go right through my car and liase with CC and see whats going wrong.

The thig is my car goes really well after the remap so somethig just isn't addig up.

I dont want to point figers but .... Im wondering in the guy would did the dyno didn't floor my car or back of the accelerator half way through the power run. If this is the case and I can prove this theres goig to be fu&king murders

Thank you for the usefull input guys.

its very easy for a skilled RR operator to skew the figures so that a competitor remap seems poor and their own great, even on the same RR with the same map its possible to get very different results.

Always go to an independent RR operator, or one who perhaps does not offer VAG tuning, never tell them its been remapped and by whom and then you may get a more genuine result.

its quiet common in the tuning world for a competitor to be made to look bad, in order to sell you one of their own maps. My old vRS ran quiet a range of power figures from just 205BHP on the JBS / Custom code RR to more than 230 on an another RR.

Dont always trust the RR, its all about how it feels, ambient air temperature and a lot more play a part in the figure that comes out at the end.

To be fair, they are all at it! Pretty much all of the chip tuning brands make outrageous claims.

The low torque figure could be related to wheel slip, what method of strapping down was used?

Could explain the use of 5th gear to try and reduce the torque transmitted to the wheels.

Also, was that a wheel or flywheel output figure?

Kev

Sorry not very clear I know but hears the print outs.

Gaz

Yup could have been slipping on the rollers

Or you may have an underlying problem

If it was me id rather run 160 than 170 on stock turbo clutch and intercooler

It's strange. It pulls really hard in 2nd. 3rd its a nice long pull and 4th and 5th are a defo improvement.

I have it in my head now what the figures are and I'm still unsure. Remapping and Dyno's are are a defo mind field.

I've spoke to custom code HQ and worst case senario. I will drive there and put it on the RR and let them determine WTF is going on.

That does look like wheel slip..

Torque doesn't really peak and give's a lazy curve..

I cant confirm it, but it's definitely an option..

Kev

On a dyno run I would usually expect a peak earlier and it tailing off. In this example it just seems to be a very relaxed gentle climb up to a peak at the redline. Not usually how a TDI dynos to be honest.

Also the 107hp at the wheels, grossed up to 159hp at the flywheel? That suggests MASSIVE drivetrain losses which is simply not the case....

If it was me id rather run 160 than 170 on stock turbo clutch and intercooler

Given the BLTs pretty much all run 150 anyway I have to disagree with that. 170 is perfectly fine, how long the clutch etc lasts is dependant on if you drive like an idiot or not.

As for this actual subject, the first thing that stands out for me is how poo that dyno chart looks. Unless its from a DynoDynamics just use it as toilet paper and dont stress about it if the car feels faster and your happy with how it drives.
