Please help - About remapping

[Rich]

Hey folks,


As some of you know, i had my Golf GT TSi 170ps remapped to 198bhp  ( according to them ) by Custom Tuning in Bradford  for £225 inc VAT  http://www.customtuning.co.uk/


I can feel the some difference but not enough to hugely satisfy me. Before i had it done, i asked them a few quests. if it was safe and could it be spotted by the dealers, their reply was this ;-

Hi richard
The tuning we do is very very unlikely to be detected by the dealers but if you
need to take your car back to the dealers for any warrenty work and was paranoid
about them finding out then if you come to us at bradford we would remove the tuned
file for you and then when you had been to the dealers come back to bradford and we will
put your tuned file back in, we would not charge you for this service.
Our tuned file will not damage your engine, we tune all our own files and keep it safe, we don't
send your original file off in an email for somebody else to tune, your engine will be running
on it's own file if you drive it flat out, we make all the major changes in your ECU between
2000 and 4500 revs and then it slowly goes back to your original tuned information as it reaches
full revs, we make no changes at all upto 1300 revs and after 5000 revs.
We can come to your house in wakefield and do it for a total of £225.
Cheers
Mick..


Quoting this part "we make no changes at all upto 1300 revs and after 5000 revs."


How is the 198bhp achieved if they dont remap over 5000 revs ?



I'm thinking of churning out £460 to have a REVO remap which takes it to 205bhp and so i read, they tune all the rev range. Is this correct ?


I really need some advice and help, what are your thoughts on this ?



Thanks,
Rgds

personally i would rather be mapped on a rolling road so 'real time' mapping is achieved, but that's just me

^^^ What VC said 

The bit about the rev ranges sounds a bit odd but it all depends at what level peak power is produced for your engine I suppose, I would expect it to be higher than 5K rpm.

IMHO a remapping isn't something to be chosen on price alone 

[Rich]

Where can i take my car to then to get it remapped on a rollin road AND that does a REVO stage remap ?


Im a total noob on this so go easy

The thing with REVO and other good tuners is that they have spent a huge amount of time and research on producing their maps.

They are generic maps but can be tweaked to suit individual cars and also additional mods.

A good REVO dealer will do you before and after runs if they have a dyno. If not they should at least log the car on the road to make sure all is OK.

[Hurdy]

I agree with hedge.

Although what you also have to remember is that a lot of maps are generic and as such are then tweaked by the tuner to the individual car if the tuner decides your car has specific needs. I believe REVO do generic maps that can be tweaked for things like intake, exhaust etc using the 3 settings on the controller that comes with most of their maps.

Not many companies do truly custom remaps for individual cars and those that do will start off with some generic coding that can be built upon by utilising dyno's and road testing. This is the nearest I have come to a custom map as Custom Code (JBS) developed their stage 2+ map on my car and it truly does make a difference.

Thats probably the closest place to you. http://www.tuninguk.net/

I wouldnt take any short cuts on a remap, go for a well known supplier. Never heard of that company you used and I live in Bradford.

TBH live mapping on the road is far better, real road conditions can't be replicated on a rolling road

My Evo was only lived mapped, and it felt far better than some simmilar spec'd cars. i appreciate that the mapper himself is the biggest difference, but still - live mapping on the road is better


Generic maps are good, very good for some and offer a wide tuning potential along with good back up.

I've got Revo on my GT170Diesel, its great, can't fault it. After trying (at my expence  lol ) several other generic options i can say that Revo delivers the right kind of map i like, the backup and support offered is superb.

[BeezerDiesel]

I can see why they wouldn't alter anything after 5000rpm on a Diesel, but on a petrol - hmmm?

The 1.4 Super-turbo charged engine has quite a big blower for the size of the engine and produces its best stuff above 4500rpm. I know a lot of companies have had a lot of trouble mapping these engines but it has been round a few years now and they should have sorted most of the issues out.

[Rich]

Yes ive been in contact with tuning UK in Wakefield - hes away for 2 weeks.


I just don't know whether i should fork out another 460 quid for a bit more bhp and have the feeling its a good proper remap

[Toptrump]

I agree with Notnormal, I had my Subaru mapped on the road.  A chap drives and another guy sits there on his laptop and they change the engine parameters every 500rpm or something giving a nice and smooth power curve.  The map the GTI has is a APR from from Awesome and while this is a simple flash I didn't feel I needed whole hog this time around as I aren't investing the same sort of money I did when I had my Subaru.

If you really can't feel the difference between your car, perhaps you should take it back and ask them to look at it and make sure everything is OK.  Perhaps even get a dyno run to see what the actually power out is.  Although this can be meaningless without a before run.  At least if you have a before and after you can see the increase/decrease etc.

I would really expect you to notice a 30bhp increase on a car.  I can't see how my GTI is a lot more than that and it is certainly noticeable that it has been remapped.

I hope you get it sorted soon Richi.
