"chipped" - Saxperience

NICK2506 · 2nd April 2009, 11:20

My mate was telling me the other day how hes gunna get his Mk5 Golf 1.9 TDI chipped.

I told him that they did bugger all.

But he said it should add 20bhp and costs around £200.

Bearing in mind hes not done any other modifications to his car at all, will this chip do anything in terms of acceleration, top speed, bhp??

I dont think it will, but i dont really understand chips. This one hes talking about...what will it actually do?? like how does it work to get more power?

Depends what chip hes onabout, if its an ebay chip then no lol.

But deisels see higher gains. My mates a4 got 50bhp from a remap on standard car.

my dad got some plug and play one.. cant remember what it is, but hes got a 3.0 v6 td vauxhall signum and after he got that thing it puts out roughly 225bhp, i think your right in saying diesels do gain a bit more

I dont understand that with a remap, ok say its standard like what youve mentioned is it the ecu that thinks its got more bhp even though its standard i dont get it lol.

Yes the VAG diesel engines respond very well to remaps. Depends on the "chip" though. Would be better looking at a remap than a chip as at least teh ECU can be flashed back to standard if necessary. No real need for a "chip"

i think when they remap the ecu john they do something with the fueling and other things but im not entirly sure i dont realy understand it either. if you cang et those sort of gains from a standard remap i think i'll get mine done lol.

Nah it just alters the fuel thats injected in relation to the air and changes the ignition timing along with a few other things.

NICK2506 · 2nd April 2009, 11:29

So he could get 20bhp on remapping a completly standard engine?

Would it screw over the engine?

probabaly more tbh

Depends what they do.

But usually just makes them work to better potential or more economically. Can reduce theyre life but only by a very small amount. All depends on what they do on the map.

from what i know...

all cars are made to a general standard so they can be used efficiently, without sacrificing basic performance whether you live in basingstoke city centre or the french alps.
the standard ecu operates to the same guidelines, otherwise theyd have to make a different ecu for different areas i guess?

iirc, all the "chip" does is tell the ecu that the engine needs more fuel, injecting times are different, more air is taken in..timing altered etc. im not a mechanic so i dont know the full extent, but i imagine thats basically what the chips do.

alter the computers thinking in lamens terms. and yes, it knackers your engine i think, same with ragging any car.

ive heard of good gains with deisels though

NICK2506 · 2nd April 2009, 11:33

God...didnt know that!

How much are you looking at to get that done though?

Totally different to a remap to a saxo.

If its the standard 140bhp diesel then its looking at the 180bhp after remap

Scott^p · 2nd April 2009, 11:35

No it wont screw the engine

How much does that cost?

Is this kinda right: to get gains from remapping a saxo you need to do mods to the engine like cams before you remap. But to get gains from a diesel, like a golf, you can just remap the standard engine?

Mochachino · 2nd April 2009, 11:38

It would only screw trhe engine if the map was silly like injection 2 litres a second (exagerated) and if it gave the driver the ability to screw the engine such as raisin the rev limiter to 14k on a deisel engine lol.

Parameters from gains from remapping are to wide. Just so happens that VAG diesel engines respond really well whereas say the PSA range of diesels dont respond as well.

Saxo engine doesnt have much that can be changed within the ecu on a standard engine, you may see a little bit but nothing much as its N/A so no boost to increase as such.

Depends totally on the type of car, engine, N/A or boosted etc...

To chip an ecu is just swapping the original eeprom chip with one that has been re-programmed.

The origional chips have lock codes attached to them so they can't be played with very easily. But when an ecu is remapped - its basically re-prograaming the oem eeprom. So chipping and remapping can be the same thing if you write the same software to each chip.

from mapping a car or chipping a car with a generic map if it is turboed you can get upto approx 40-50 bhp more power. they basically alter when the turbo kicks in and often utilises slightly more boost.

for instance with the vauxhall diesel engine a few companies sell tuning boxes for them.

they have a map on them and for instance-

150 bhp astra mk5 cdti 1.9+ d tuning box= 190 ish approxomately.

so it can be done. i would recomend getting a custom mapping session done as no 2 cars are the same. so your mate sounds about right as long as its not an ebay resistor that is teling your car the engine is getting boat loads of coold air. i hope this helps.

Vag diesels respond very well indeed to remaps my mate has a pd130 fabia vrs which made 155bhp after a stage one map.

The vag 1.8t respons well to a remap also.

My Leon cupra which was 180bhp standard made 216bhp after just a p-torque remap and forge diverter valve.

Cupra r's are well known to achieve 250 - 260bhp from just a map.

titchster · 2nd April 2009, 15:31

VAG PD engines (which Im presuming his is) respond very well, Im presuming the Golfs are PD150s, a Custom Code remap, which costs in the region of £300, not £200, usually takes the engine to 185-190bhp. And the torque is pegged at 290lb/ft, as the standard clutch starts to slip at more than 300lb/ft, and the usual replacement is a Sachs clutch, at about £700, so the torque is pegged to save the customer so much extra money.

Sorry, been looking into it.
