Hi

I am getting a custom remap done in a couple of weeks on a 55 reg Fabia VRS. I want to avoid the DMF vibration I read about on here, For those who have remapped, at what RPM does DMF vibration start and how much torque does your map graph show at these RPM?

My thinking is to preserve traction, clutch life and avoid undue DMF fatigue by keeping torque down around 265lb/ft max. Have this torque reaching up the rev range to 3750 RPM or so and that equates to around 190bhp which should make it nippy.

I dont want to "drive round it" as I reckon the traction on wet country lanes will improve if the torque is kept linear as well.

All advice and comment greatfully received.

Who is remapping it for you because IIRC the CC1 (custom code) remap has done exactly what you want, limited to torque to 280 lb/ft but holds it to well over 3,000rpm with no clutch slip (speak with Josh a member on this very forum or JBS).

Also other tuners such as Jabba etc who do custom remaps can tailor the power to your specification so that you can have exactly what you want

My Jabba map has been running a consistent 300+ lb/ft of torque now for over 30,000 miles and I still haven't noticed any clutch slip, I guess it down to the way to drive it like you said. Don't floor it at 1,500 rpm, in particular in higher gears e.g. 50 mph in 6th ( why would anyone want to do that anyway :confused: ) and you'll be fine, I think too there needs to be some clarity here on this:

You can still accelerate quickly, but just not at full throttle for about 500rpm thats it (1500-2000).

And even if you did once in a while, you would still have a long life left in the clutch, it's only if your doing it every day of every week, full throttle in higher gears at the rpm's mentioned above that you will experience real clutch slippage and potentially need a new clutch, and it won't be after 1 week, like I said IMO it would take a while.

Hi

Jabba are doing the remap and this question was to help me decide exactly what I want. The Jabba torque graph they show on the website shows torque ramping up earlier in the rev range than the standard car. It seems that at just over 2000 rpm, they have the same torque as the standard car has at just under 2500rpm. I wonder if it is this early build up of torque that sets off the DMF vibrationas people report it at around 1900rpm onwards? Oddly, the manufacturers claim 229lb/ft at 1900rpm.

I want to avoid having to drive round "unsuitable" areas of the engine performance. The finished map wants to feel like it was the way the factory would have done it, not a bodge job. I arrived at a 265lb/ft figure as an estimation of what it is reasonable to expect in over engineering or design safety margin. Looking at superchips graphs for te PD lump, they also take 265lb/ft as peak torque, and interestingly, their torque ramps up along the same lines as the standard setup, it just goes a bit higher.

As for accelerating hard from low revs in top, I thought that was part of the appeal of diesel engines? On the M62 / A1 / M11 today for 3 hours and like the way you can just plant foot and go. I need to retain this driveablity without worrying about lunching the DMF / clutch.

Anyone else got DMF vibration and knows how many lb/ft at waht rpm?

I appreciate your point but I will refrain(m) <- cant remember which! from making further comments, but trust me, you'll be fine with a jabba map, especially if it's the custom map as they can tailor it to your preference and you should have no DMF probs, however I don't have any probs i'm running a lot more than 265 lb/ft. But if that's what you want it's a

190bhp which should make it nippy.

The standard car is 'nippy'. My 170 (ish) bhp AmD map is more than nippy. 190 bhp is, well, enough for this car. Stop worrying, just do it.

And i'd doubt certainly doubt the claim of 190 bhp

Remember, numbers are used to sell a product and to give a wow factor to the dyno boys and in pub talk, but it's actually the way it drives that is more important. And my Jabba remap makes me smile from ear to ear

were did you get your fabia vrs remapped?im also from cumbria and want to get my fabia vrs remapped.

cheers marra

excelent use of the search,a very good quality,there are a few members on here with the amd 1 click for sale,chrisrs and wardy are two of them off the top of my head,if you look around(north west meets sect,malt house meet)should turn both users up,pm them and you too could have amd 1 click:thumbup:

i have the custom code and it is rated as one of the best to retain liniar performance and no clutch clip i am having mine rolling roaded in january so will let you know highly recommended

mine has been re mapped. No clutch slip or DMF vibration. Hopefully this means its a milder re map. Its still dam quick though

My car was remapped by Star performance upto 180bhp, no idea when it was remapped but at 40k miles the car needed a new clutch and flywheel, so i got a Helix clutch and SMF.

My friend also has a vrs and he has clutch slip 42k miles and he is only running around 170bhp

Clutch slip has nothing to do with peak power and everything to do with peak torque.

hi

im new to owning a fabia VRS and looking into getting it remapped soon just wondering what is DMF vibration.
