Just thinking about an ECU remap

[rashg60]

what was your old dv like? Also I find when I don't drive mine much or without giving it the beans it does start to feel flat. Get it nice and warm and go for a good drive, going through the gears. Nowadays I make sure to give mine a good blast in a few gears daily and I have not felt it go flat since.

Check your oil levels too.

I think you hit the nail on the head usmangti - I just took the car out for nice long blast and boy does it feel good. The smile is back on my face.

I actually hardly drive my car and barely cover 200 miles in a month, so your advice on taking it for a nice long spin was perfect.

So if it loses boost again, chances are the DV is the first culprit to blame?

I do a hell of a lot of short journeys in mine, and after a while, even once it's properly warmed up, it can feel decidedly flat.

I recently did a 400 odd mile round trip, plenty of A roads, motorway, varied driving, and the car certainly felt much stronger after that. Now after more of the short commutes to and from work, I'm sure it's gone a bit flat again.

I used to think the old 'ECU learning' thing was a bit overstated, but with this car in particular there's something in the theory.

I think they call it the 'Italian Tune-up'!

Also, about a week after getting a new rev G dv, pcv and cam follower, the car seemed to get even stronger and smoother than the obvious improvement straight after the parts were fitted.

All that said.... I'd still get it down on the rollers at R-Tech. Just be sure of things.

Glad to hear it feels better. Yeah I would defo agree if you feel a loss of power dv would be the first to check. The last time I changed my dv was because it was feeling flat but there was absolutely nothing wrong with it. Swapped a Rev G for another Rev G. However at the time I was rarely driving the car maybe once a week, now I drive it 4 days a week and do about 50-60 miles it feels a lot better. A good old "Italian tune up" does the trick or extended drive clears any issues with boosting.
What @AJP has said about ecu learning I think is spot on and I have never felt it more than with any other car than this car. Also I have read and feel like it might be right that you don't always get full boost if you just floor it WOT, what is better is to feed the power through smoothly. Might be worth mentioning my car is standard ie not remapped.

Fantastic advice usmangti - I will be less hasty next time and just give it a nice long drive instead!

[usmangti]

you're welcome

I think I've broken the Rev D as well! The car seems to be losing boost again - it's only been a couple of weeks!

I have now ordered a Rev G. Hopefully fitting it tonight if it doesn't rain.

I didn't realise the DV was going to be such a pain - maybe I should have left the car stock. The old Rev C had been on the car for 64k miles and still going strong. It wasn't even split or anything.

Replaced the DV with the Rev G today and also replaced the PCV with the latest revision.

The car is back on track and feels perfect once again.

Now time to enjoy it again.

Better than the Revision D then?

[rashg60]

Yes definitely - at least I've tried both!

I just hope nothing else goes wrong now.

Good to hear. Fingers crossed it stays that way.

I'm off to R-Tech myself tomorrow for Stage 1

[rashg60]

Have you already upgraded your DV/PCV?

Like I say, mine were fine when the map was done - they just went doolally post-map.

What other mods you got to compliment the map?

Good luck with your map tomorrow - you'll defo enjoy it

Yes I had a new Rev G, PCV and cam follower a few weeks ago. I always had a remap in mind since I bought it in April, and it didn't quite feel like 200bhp should anyway, so it needed doing.

The Rev C DV that came out was indeed split, and full power was restored! It's been running spot on since.

The car will be a true Stage 1 - everything is stock. I have run it exclusively on V Power so it should map to its potential on standard hardware.

I may go for an uprated downpipe, cat, inlet etc if I want to go Stage 2 in the future, but certainly not before I uprate the brakes. They're a bit weak even for standard power after a few big corners. I'll probably go for TTRS calipers and 340mm discs.

Quite looking forward to tomorrow's events!

We are in similar circumstances AJP: I bought my car in March this year and have only upgraded the air filter to a panel K&N and have only ever used Shell V-Power. With the Stage 1 map that's all this car needs. The stage 1 brings this car up to it's true potential without any further mods.

I think anything beyond a Stage 1 you need to start spending serious money, i.e. brakes, clutch, suspension, tyres, exhaust etc. For that sort of money I'd rather purchase a newer Golf.

Let us know how tomorrow pans out. Where are you travelling from to R-Tech? Either way, your journey there will be much much different from your return journey home.......

[AJP]

Heading down the M1 in half an hour. I'm near Sheffield so I'm giving myself plenty of time to crawl through the never-ending 50mph cameras..!

Yeah, power-wise, we'll see. If I get to the point where I'm wanting more and more I think I'll look for a mk6 R or S3, rather than turn everything up to 11 on the mk5.

Will update later. Cheers!

242bhp and 296lb/ft

Happy with that! Really smooth power delivery and the torque makes it effortless. Great work by R-Tech again
