She's a 105PD with 20k on the clock and i've got her booked in for a date with Dave Wishart @ Torquetronix in Kells first thing Saturday morning.

He reckons he can map her up to 150-155 bhp with improved fuel economy. I already have a Pipercross Panel Filter, done the cage mod, use BP Ultimate & a snifter of Millers so this should be interesting

Anything else (cheap) that i can do ? Should i be looking at a better clutch or will the stock one be ok, provided i dont try any energetic launches ? I'm getting this done more for overtaking grunt and better fuel economy than boy racer antics (too bl00dy old!)

Wish me luck

be sure to let us know how you get on, are yu have it rolling roaded before hand and then after?

as far as i am aware the car will get at least one rolling road session during the appointment. I may ask for one beforehand as i'm pretty sure with the mini-mods i've done already she should be pumping out more than 105bhp - i know i drove another pd105 recently and it just didn't pull quite like mine does.

IMO figures are all pretty subjective anyhow - i have a freind with a BMW 535d Bi-Turbo and he recently had it remapped adding another 50 or so BHP to the already mental 275 BHP it had - doesn't sound like much in the great scheme of things. The car was very quick before, but now .... jesus christ it feels like a jet fighter! My buddy never gets tired of telling everyone that it's got more torque than a Ferrari 430 Scuderia

Anyhow - i'm babbling! I'll report back after i've had a decent chance to "evaluate" the performance increase :D - either that or my Octy will deliver me briskly into a deep ditch :P

eh - wanted to expand a bit.

Hi there! I've got a 1.9PD 105BHP and I'd be interested in what results you get. Quite happy with what I've got but always interested to see how far you can push it! BTW, how better will the fuel economy be? Also, does it make the engine louder??

been to TT a couple of weeks ago - great job! and makes such a difference

just had my vrs diesel "bluefinned" this afternoon, whole process took 1hr and after the 1st drive really really really happy, not a mental difference but enough to put a smile on my face

Dave does a great job, he remapped my Astra. 150hp/230lb-ft to the 200hp/310lb-ft monster it is now.

Once she's remapped, consider shortening the oil change intervals. Mine beats the crapola out of the oil now, it's shot within 10k. I see you've 20k on yours, if you havn't had the oil changed yet, I'd certainly think seriously about getting it done before or very shortly after the remap.

She's due for a service soon but i might do the oil and filter myself in the next week or two .......

so... the results.....

First off ... has to be said that dave is a brilliant bloke, and i have to commend him for the effort he put into mapping the car. i was down there for nearly the guts of 4 hours and he really stuck with it despite having a queue of people waiting for service.

dave had done a custom map because i was a member of Briskoda and he reckoned she was pulling about 150-155 bhp but there was a problem - at 2000 rpm i was getting a bad shudder under hard acceleration in 4th gear. dave modified the map several times but couldn't get rid of the shudder totally despite pulling the torque curve down until after the turbo spin-up point (or something like that). at one point, the ECU locked up half way through a flash procedure and he managed to get it back up again!

the car is pulling like a b*****d in every gear but i've still got the shudder. dave (and myself) reckon the DMF could be the culprit - i was previously getting a slight shudder at takeoff and before turbo and had considered it might be a bit weak, but the remap has definately made it worse.

any thoughts guys? should i take the car to my local stealer and demand a new DMF? the car is less than 2 years old so i guess i'm still under warranty.

anyhow - no exact figures unfortunately but i can say that the car feels much more capable, and when you press the loud pedal it gets very fast very quickly - jury's out on fuel economy so far, but i'll try and get some figures over the next few weeks.

In order to get the part changed under wty you'll need to be able to prove that the car does it without the remap and of course have it removed before you go there.

My thoughts would be that you've simply got too agressive a map on there, I suspect you are pulling a lot of torque, too much for the DMF.

good to see another NI member on here, coincidently I got my Octy mapped today too, although I used Auto-tune, also in Ballymena, must say Im very pleased, Ryan rolling roaded it before and after the map to show me the difference and its a nice smooth map

Not a hope of a new DMF under warranty if you've remapped it as they are only rated to a certain torque.

They do a single mass flywheel for the 1.9 with the 5 speed box IIRC, but I could be wrong.

dave must be doing well - he had to move his 1 week old red 911 turbo out of the shed to get my vrs in

there also was an m3 convertible, scooby, westfield with hayabusa engine and a fancy quad buggy thing sitting around

I have exactly the same problem at 2000-2500rpm if i push it hard i will get quite a shudder also but i have learned with this one to downshift a gear so it doesn,t happen.

i'm of two minds about this remap - i love the power of the car, but the vibration / shudder is doing my head in. it's got to be said that it's very brief - 2000-2200rpm or thereabouts - what i'm more worried about is the DMF exploding especially since my better/prettier half does most of the driving and if it went BOOM on her we'd be in real crap. i like the idea of the SMF just concerned about cost!

something else i noticed - if i give her the beans in 3rd gear, the ASR goes nuts - could this have anything to do with the vibration? i'm probably grasping at straws cuz the prospect of forking out hundreds of quid more is making me all cold and clammy!

encephalopathy - yup ... thats pretty much what he had down there on saturday, plus a couple of quads.

daz_pd - there are a number of "norn iron" guys on here as far as i know

"They" being ?I had a brief look around the net and i haven't had much luck :(

They being the DMF itself and the clutch.

Put too much toque through a DMF and it will fail prematurely.

In terms of the SMF, Skoda mentioned it to me for the PD105 when used as a Taxi, so they is skoda.

Sorry for the confusion, i meant the second They :)Cheers Mr cheezemonkhai

There is one simple rule to remember when modifying your car -

If you want to play be prepared to pay.

It might not cost you any more in terms of repairs etc, and in general it doesn't but you have to be prepared to do so if it does.

If you have concerns about your remap then you should discuss that with the tuner, maybe ask him to detune it slightly. Most all TDi's with a remap will judder to some degree and it becomes an art form to be able to 'drive around it'. You may just need to adjust your driving style.

My buddy never gets tired of telling everyone that it's got more torque than a Ferrari 430 Scuderia

Has your mate been coming in for some stick on Pistonheads recently by any chance

What did Dave say about the shuddering? Did he take it out himself for a test drive?

Wen he did my Astra he mapped it, took it down the road for a rake with the laptop plugged in, then adjusted a load of stuff when we got back.

Chipped my 1.9TDi (110BHP) with an MTM chip. Got the same vibrations you are talking about in the low RPM area. (just about where the turbo kicks in). Chip was replaced with another chip with reduced torque in the lower area...vibrations gone.

Btw: It seemed like the vibrations got worse in cold weather :/ Better cooling => more power? Don't know...

no idea, but i'll be sure to ask him.....

Dave reckoned it was the flywheel being weak - he modified the map a load of times to take the torque down but he said he didn't want to take it down too much because that would make the car pull like crap all and then suddenly surge forward. i've tried driving around the problem but it's spoiling an otherwise excellent job - the vibration is coming in right around 60mph in top :(. Dave was under pressure on saturday so maybe there was more he could have done - he did say if it was ****ing me off to give him a call, which i may do later today and see if he can have another look, or failing that, return her to stock settings until i can see of skoda will replace the flywheel.

I have spoke to SUK this afternoon and described these symptons which also is like mine and they were very helpful with this and insisted that i take it to a dealer as it is showing signs of a DMF problem and would replace it under warranty.

is yours mapped, and if so, did you happen to mention that little nugget of information ?

i just noticed something else...... if i turn off the traction control the shuddering gets significantly less noticeable - it's still there, but nowhere near as intrusive.

i'm still pretty sure the dmf is w**ked or at least heading that way but could it be that the traction control is trying to reign in the extra power and failing miserably ?
