Re-Mapping Complications

Gerrard_8_lfc

Hey guys.


Would increasing the breakhorse power of an older Golf have any adverse effects to the standard engine given the age and miles it has already covered ?, I don't mean to horse it up and down the country but to give it a bit more power through the gears i.e 2nd to 3rd gear ect.

The engine would be a VW Golf 2001 Reg 130000 Miles on the clock, I would be looking to take it from the 90 - 115 or maybe 130 bhp.

Cheers

Why not just buy one with more BHP it will be cheaper to insure than a modified car.

Its Just my second run around car, I was under the impression it would be treated asive it was a 115 bhp Golf i.e the same price should the golf been that one originally?.

You wont get an extra 25bhp from a remap.

Because this is MSE and it is cheaper to remap a perfectly good car than sell and buy a new higher powered one.

Though somebody as knowledgable as you will know that same model cars with different power outputs are very often nearly identical mechanically.

In relation to the OP, I wouldn't buy a 90 to remap it, but a 115 would be a better bet. I did read that there are some differences between the 90 and 115 models, but there where few if any differences between the 115 and 130 tdi models, this information is unsubstantiated, though I did look under the bonnet of a 115 Golf and 130 Passat at work once when two of the lads had bought new cars, and there seemed to be no obvious diffences between the engines.

It is possible the gearboxes could be different in the 90 and 115 but the same gearbox in the 115 and 130.

Sadly, I read this in a VW mag several years ago and can't remember the details.

Maybe you can get more accurate info from a VW forum?

You would be surprised, especially with these new turbo diesels.

On the Mondeo forum there are plenty of blokes with a dyno proved increase of 25 bhp, sometime a little more, the 130 TDCi seems to be a particularly good candidate, with 160bhp regularly obtained.


There are lots of people that get a good increase on VAG engines, the TDi VRs is very similar to the 140tdi, but has 170 bhp, and can be reamapped for almost 200bhp, maybe with a better airfilter added.


Though ooutrightpower figures aren't the onlt thing, the improved drivability alone make a remap worthwhile.

Especially on something lie a 140 tdi VAG lump as they do suffer from a bit of hesitation when pulling away from a standstill, which was cured on my mates Audi A4 by a remap, it also went like stink afterwards, I honestly would beleive it had well over 160 bhp afterwards, the improvement was really that impressive.

The OP has a W reg Golf.

He already owns it. Can't you read?

It's worrying to think they let you loose on the public.

LAS my arris, your not fit for dial-a-ride.:D

At least I have a job, you really need to get out more, you are getting all bitter and twisted.

My advise was generalised, or can't you read, also the OP didn't say he had a W reg Golf, just a 2001 model.

What does this mean " i wouldn't buy a 90 to remap", in other words I am commenting that I wouldn't start with a 90tdi.

What does this mean "but a 115 would be a better bet", in other words the 115 would be a better starting point than his 90 tdi.

Then this " I did read that there are some differences between the 90 and 115", in other words it may not be as simple to remap the 90, and that any mechanical differences need to be researched.

However if you read the reat of my post you will see that I read in a VW mag years ago that there are few differences between the 115 and 130, thus making the 115 a slighty better candidate for a remap.





Gene next time you want to attempt to slag somebody off, make sure you have understood what they posted first, otherwise you just make yourself look silly.

Then don't make a mistake in your post, I think you will find that you can't actually get a 2001 W reg Golf, only an X, Y or 51 plate.

Well the 115 BHP TDi is a PD engine for starters 90Bhp engine is not.... Remap and bigger Larger injector nozzles is the usual way for a 90bhp tdi upgrade... Not 100% sure what turbos these use so cant really comment further as regards turbo upgrade.

TDi Club forums will be your best bet... Lots of Homebrew TDi tuning on there.
