Hi

Visited JabbaSport today for a remap. Having read a number of posts about DMF vibration and clutch life, I decided to go for a conservative custom map. As a starting point, we had the car standard and saw 137 bhp @ 3672rpm and 350Nm (258lb/ft) @ 2502rpm.

A PD160 intake and green filter were now fitted. In order to have a progressive drive, I elected to keep torque limited an thus we capped it to 383Nm (283lb/ft) @2864rpm. Torque was maintained out as far as possible by trying unusually high fuellig from 3500rpm, yielding 193bhp @ 3855rpm and revving healthily past 4500rpm. The test drive reflected the figures well. The peak power was accompanied by a bit of smoke and from the drivers seat it felt a bit like "overdoing it", so fuelling around 3500 rpm onwards was backed off down to normal (for a remap) parameters. This removed the last little kick from the power, but nothing significant enough for my impromtu 4th gear timing to detect.

Performance is obvoiusly up.60-80 was 4th 5.2s, 5th 5.3s, 6th 6.3s. New times now 4th 3.7sec, 5th 4.6s 6th 5.9s This shows the performance improvements mostly in the upper rev range.

It now drives very well. In normal driving, the car is much like a smoother stronger version of the standard car. When you ask for more go, the car pulls as normal from 1500rpm, but where the car used to get up and go up until 3000rpm before tailing off in disappointing fashion, the car now pulls noticably stronger up to peak torque, then just keeps pulling with the same insistent force all the way out to 4000+rpm. Gaining power through an extra 1000rpm does not sound too impressive until you consider that the gains are across over 1/3 of the useful rev range.

The way the power fell off with the standard car rendered 5th and 6th almost equal in acceleration at higher speeds (up around 80 - 100mph). Now 5th provides serious shove past the 100mph mark and it is now worth using. I dont know what top speed is yet, but when I get a chance to visit an autobhan, I will report.

Downsides? We will have to see how fuel consumption goes in everyday driving, but I would expect an improvement. Will report as I find out.

Mission accomplished then. No DMF vibration at full throttle at any revs, so no need to drive around any dodgy bits. No more smoke than the standard car. Excellent driving experience. A big thank you to the excellent staff at JabbaSport and to Briskoda for the group buy. I did not get the name of the guy who did the remap, but if you are reading this, thanks again.

PS I kept a nervous eye out of the window in case I was being watched by the warranty police (Eastern block habits die hard I guess, KGB alive and well in SUK).

More than likely it would have been Michael...he's the one going bald (sorry Michael:O ).

Sorry cannot do that or the warranty police will look at my hosting address and void me. I will see if it will fit in my sig.

Host your scanned dyno plot on imageshack or fileshare.de

EMail it to me on MSN, with any editing out of details and I'll host it.

Yes please! I'm in on the 2nd of May, and would like to be able to compare!

Is 193bhp a conservative map? Will be interesting to see the graphs too

Chris

Would like to see this graph seeing its been cap'd.

Is 193bhp a conservative map?

Chris

Just what I was thinking :eek:

The only difference I can tell between that map and mine is that mine peaks with 30 lb/ft more torque. I have to say it's hit and miss with DMF vibrations, mine is fine after 30k on the remap, however others have commented on vibrations after just 5k.

My car/map is soon to be tweaked however so the DMF may vibrate then .

You can hit very high bhp and have the torque restricted, bhp max will hit at high revs where you're way beyond peak torque figures anyway

You have PM.

Bugger, never thought of that:rofl::rofl:

And here it is. It must have been on the old rollers because its a different pattern to my plot. Only 30bhp and 100Nm less than mine. :eek:

Hi

Interesting that standard cars torque is the same as the Seat PD160 is rated IIRC. That capped torque may well help get it off the line quickly and keep it hooked up in the lower gears, also may make it easier than a full house remap punting it along in the wet?

Another thought, if boost in the midrange is being limited a bit, will this reduce intercooler heat soak making for better or more consistent top end power?

Chris

All depends on boost pressure. The higher it is the hotter the turbo gets. So if its using a lower boost pressure then yes it should reduce heat soak a little but with my experience the std intercooler can't deal with the standard boost pressure anway.

Nice graph

DMF Vibrations?

DMF Vibrations?

dual mass flywheel. It has to cope with the greater power of the engine.

Hi

Two days commuting on a 60 mile each way mix of city and A / B road driving has seen a distinct improvement in fuel economy. Was running average 46 / 47mpg, now running 49 / 50 mpg. Have not been hanging about either. I get the impression that is it drinking a little more on the motorway, but need to look at it more closely to tell for sure.

Ann Onnymod

Have you seen my PM to you? It's important in light of your warranty concerns.

I thought the Czech secret police were the Stazi?

OK, thanks. Would this be removed with a better flywheel when changing the clutch then, if you're going 190+ bhp.

It's not the BHP which is the issue, it's the lb/ft of torque, in other words - cars pushing more than 320 lb/ft of torque might aswell get an uprated clutch/pressure plate. Mine is 323 lb/ft of torque and it's right on the limit of the OEM clutch, I have however managed over 30k on the clutch and with gentle throttle application around 1800-2000 rpm I see no reason why mine won't do another 30,000 miles if not more undisturbed.
