Do you want a spare Golf GT front bumper? My car has gone but the spare bumper I have still remains here - It's black and is missing the inserts but you seem to know what you are doing!

Thanks for the offer but I hopefully won't need it!

I wanted your R32 lights...... :(

Ok, so the remap has been on for about 40 miles and while it's definitely better I'm not blown away, should I be?

I was just the same, I took it off again and noticed a bigger difference going back. Shark RR soon so I'll get a better idea soon

Thanks mate, I gave it a little bit of beans yesterday and I definitely noticed the difference particularly how much further it revved before peaking. I think the problem is the power delivery is so smooth so I don't notice it so much as the vRS although it is much more like driving a petrol now. I might put the standard map back on a try it like you have......

Thats just what I noticed. The PD140 has quite a shove as standard and Shark's maps are so smooth it feels slower as you don't get that shove. Having said that my MPG is much higher, out of 6 fill ups since fitted 4 have seen over 51mpg

I've attached my vcds logging, time between each run was the time taken to upload the map, carried out on the same stretch of road

Did say before you applied that it would drive more like a CR

Depends whether you've driven one of those though

You could always disconnect the battery overnight, then next day go out, get it warmed up, then go for the Italian Tune-up option while the ECU in adaptation mode

What??????

Sorry, throw-away remark. A bit of an old school term now, but the approach is the same.

http://en.wikipedia.org/wiki/Italian_tuneup

Would basically consist (in my approach) of using wide-open throttle in several sessions, upto the safe extents of the rev range through 3rd and 4th perhaps, where safe road conditions exist of course. This will allow the ECU to be asked for pretty much the maximum amount of air and fuel required.

I have done this before many moons ago but I was just wondering about disconnecting the battery and the ECU adaption cycle......? Don't remember doing that. :S

Battery disconnect will just reset things, ECU then has no values to work from, so is going to have to start from scratch, hence the 'adaption cycle'. So then going and extracting the maximum safe, accessible performance from the car should, in theory, yield the most positive results possible from the remap.

That's the theory anyway

Are there any dangers in doing this to a modern ECU?

No, none at all. All you're doing is preparing it for future use

It's just a thought mate, a possible course of action, to see if that has any effect on remapped performance. Adaption should happen over time anyway, it's just this way is a method of accelerating that adaptation.

I may it some thought. Tbh I still haven't given the car a significant run, and I certainly haven't taken it to the extreme. Thinking about it, perhaps Ben has done to good a job with the remap, instead of the grunt I was getting from standard its now a far more subtle, but sustained power delivery.

On a different subject, GTi headlights will be going in today (weather permitting).

EDIT: Weather permitted.

During -

After -

Imo, they look soooo much better, and considering they are OE units and I paid less than 50 quid for the pair including delivery I'm well happy.

And before anyone says it, I will be returning Brimmas blanket......

EDIT: Comparison picture -

Nice GTi rug too

Great deal at that money. They're not mega different, but a subtle improvement with the darker internals.

Looks rather tidy

I didn't notice

In the flesh there is a massive difference.

It's certainly getting there, thanks Rob.

Next mod, I am going to have a go at spray tinting the rear lights to see if I can recreate the R32/ED30 effect.

Having attended the Shark RR day today it became very clear why the car feels slower with the map on, just look how smooth the power curves are

Peaking @ 170bhp & 390nm (approx 290ftlb)

OT I know, but can someone explain why torque goes down while power continues to rise? Is the extra power just converted to noise?

Serious question too, not taking to michael....

This is a simplification; if you want proper formulae etc use Wikipedia - Power is a direct function of both torque and engine speed.

ah, so the extra "power" is taken up driving the engine faster, but the actual output torque is reducing? That makes sense. Sort of dynamic losses inherent in the diesel engine then....

Not really but sort of (there are other factors involved as well, hence the recommendation to find the maths for yourself if you're really interested); Depending on the gradient of the torque curve, the engine speed can be rising faster than the torque is dropping above the peak, and so the power rises. Past peak power, the gradient of the torque curve is steeper, and so the power drops.

It's been a while since I last posted on this, mainly as the vRS has been receiving some treatment, namely S3 front brakes, Milltek downpipe with sport cat and Shark stage 2 software......

Things have been quiet with the Golf but I have now made a few additions. I recently got a set of GTi side skirts, lower spoiler insert from a member on the mk5 forum, I also got my hands on a complete GTi brake set up also from another mk5 forum member, this was manily so I could have the vRS rear brakes refurbished to match the S3 fronts, but as I had them I thought it would be rude not to upgrade the GT to 312mm fronts. Anyway, the spoiler insert was a 5 minute job and makes the front look a lot better, I haven't got any pictures but I'm sure people know what they look like. With the skirts I really wanted them coded to match the front and rear spoiler and valance, so I attacked them with my random orbit sander to knock back the texture, then gave them a couple of coats of plastic primer, two of the colour and three of clear coat, I then wet sanded with 2000 grit and run two passes with the machine polisher, very happy with the results -

Apologies for the dirty car....

Looking very nice, has wifey noticed the map yet?

Nope....

There's not much hope for the girl, she hasn't noticed the stopping power of the S3 brakes, or the fact the vRS is now running stage 2 either!

Looking very nice. Well, not that it didn't look nice before, but you know what I mean
