Anyone Used One Of These Before

[big boy stevie]

hi have any of you guys used one of these and are thay any good, or is there any horror storys in using them ie causes damage or poor running. thanks in advance steve

Save your money, or if you must - go to Maplins and ask for a 280ohm resistor for about 2p and fit that instead. Its nothing more then that in a fancy package designed to fool the ECU into overfuling, which In reality can cause all sorts of problems with running and will almost certainly lower your MPG - any "performance" increase is likely to be minimal and more likey to be a placebo effect.

thats what i wanted to know, ive heard you can increase the bhp and make them quite quick but thought this was to easy. cheers steve

[Willie Krashitt]

As I have said before, if it were that easy then the manufacturers will do it. Upping power by overfueling will do one/some/all of the following:

 

Increase in cylinder pressure considerably - leads to blown head gasket or cracked heads if sustained

Increase exhaust temperature - overheat exhaust valves and turbine wheel in turbo.

Increase smoke - obvious to anyone following you and your EGR system will clog up faster/bores will polish quicker

Increase the amount of fuel going past the rings (as PCM thinks engine is cold, therefore advances injection) = contaminated oil.

Increase fuel consumption - more power = more fuel used.

 

These "hot chip" companies work may well work "reliably" in lighter vehicles where the engine cannot be maintained on high load for very long, but the Galaxy is a 2-ton + passengers heavyweight.

 

It takes up to 2 years for manufacturer calibratoins to become fully mature and set so vehicles are reliable and meet economy and emission targets, but 20 minutes for a numpty with a laptop and no test equipment other than a rolling road who knows better than all the Engineers working for the manufacturer to make your calibration better? Draw your own conclusions.

As I said at the beginning, if it really were that easy, then it would have left the factory with it.

points taken i wont be buying one then thanks guys you have to ask these questions never had a diesel in my life so a whole new kettle of fish to me, i know my way round a petrol engine but not diesel im sure i will learn ive done enough work on my petrol gal over the 4 years ive had her so im sure i will learn about diesel's, i do have one diesel at the moment and thats my dog his names diesel he was all dirty when we got him hence his name.

 

thanks guys.

Lol diesel the dog, love it :o

 

From general reading it would appear the VW TDI's don't really like being fiddled with that much - quite a few horror stories even with proper rolling road remaps :)

looks like i wont be going down the chipping and mapping route then will just have to make the beast look good, still got plenty in mind for her though just got to wait now for the money and then i can go buying,

i cant wait at least this time i wont be desperate to buy the first one i see our present bus was needed bad as we didnt have a car did look at quite a few dogs though, mind you was a good find 1 owner from new aircon that works just a few war wounds, and normal galaxy stuff broken horn buttons, broken speaker grills, and the high level brake light not working which turned out to be broken wires in tailgate,

has been a very good car with only a few things ive had to do really 2 rear shocks, a back box, dog bone engine mount thing, top mount and front shock, droplinks, tyres, a few service items and thats it, she passed her mot every year with a few advise notices which i done, new owner will be laughing a very reliable car for us will be sad when the old bus goes but cant wait for the new one.

Depends on the fiddler in my experience......the maintenence given and the state of the engine prior to mods.

 

I have read and read about the best practice and the best tuning options on the VAG 1.9 TDI Pd (130) and have only come across a couple of bad news items.

 

WILLIE KRASHIT: These statements are ill advised:

 

Quote a) "more power = more fuel used"

NOT ALWAYS....If a car is tuned better then more power will equal LESS fuel used as the engine does not need to "WORK" as hard to maintain the performance.

 

Quote B) These "hot chip" companies work may well work "reliably" in lighter vehicles where the engine cannot be maintained on high load for very long, but the Galaxy is a 2-ton + passengers heavyweight.

If this were true then surely the std engine will fail much earlier than in lighter vehicles !!!!!!

 

Please if you feel the need to give advice or guidance then 1: Balance your information and 2: read up properly.

 

Most engines are de-tuned to accommodate massively wide variables and thus can be tuned to a better more focussed purpose.

my mate had his chipped and is quite happy with the results better off the line and better econmy, not sure how he chipped his have to find out but he was well impressed, and i suppose everybody has opinions on these thats why i posted this to gauge interest.

[Willie Krashitt]

Matt1e,

I speak from facts - my job is that of an engine calibrator, using equipment that measures all the engine presures and temperatures, cylinder pressure for each cycle in each cylinder, emissions, water flow, fuel flow, turbo speed as well as the obvious power and torque readouts. The advice I give is 100% based on fact.

Ok, there is a very small allowance for max/min limit component effects, but you would never know (nor would any chipping company) whether your parts were max, min, in the middle or somewhere else.

As to the fuel to power equation, the diesel engine converts fuel into torque almost linearly, ie the more fuel you put in the more torque you get until excessive smoke, cylinder pressure or temerature call a halt. I agree with you that you can get a little bit more power at any given amount of fuel going in if you optimise the injection timing, egr rate, fuel pressure, boost pressure for that extra power, but you will compromise something else - excessive NOx emissions, higher smoke, combustion noise as well as the engine damaging issues I stated in my earlier posting.

 

As I have said many times before, if it really were that easy to up the power, it would be done in the factory. The differences between 115 and 130PS PD engines in the Galaxy amount to: Head gasket, Injectors, turbocharger, Intercooler, Complete air cleaner assembly, Exhaust system and Water Pump (excess heat has to be got rid of somehow). That is just the big hitting items, and doesn't include a miriad of other bits.

These are the FACTS.

George,

 

Please.....As an engine calibrator then you accept the huge variances and thus the trade offs needed to cover each continent. Europe goes from near equator to near artic as such the manufacturing tuning has to be able to cope (without issue) in each area. This is what most respectable/knowledgeable tuners exploit for more power/torque.

The manufacturers have specific marketing profiles to cover and they manage costs by having an engine (and other items) cover as many as possible to maximise efficiencies on cost and push up their profits....

 

Why wouldn't a tuner know the facts about each and every component ? As their reputations are on the line it is in their interest to know these things. If we didn't have tuners (or tinkerers) then we would likely have a very stagnant motorsport world. Motor sport is where the standard engine can be pushed to its limits and we then get a "street" variant of these tunes within the tried and tested limits.

 

A Diesel would (if allowed) suck more and more fuel in until destruction of the components which, I'm sure you know, is why the accelerator is not actually that it is a regulator restricting the fuel allowed into the cylinders (PD is subtlely different in this respect).

If you balance better fueling with better air then why would combustion temps increase ?

 

The PD TDI family is that of: 90/110/115 (same engine in varying tune) then as you correclty state the 130 with the differences as you describe. Which essentially was followed by the 130 "tune-up" (incl intercooler) for the 150 which never sold here in the UK.

They have now changed to common rail injection on the 2.0 engines.

 

Funny thing is that you appear not to like tuning and are entitled to that opinion but don't do the generic scare monger.

If you have the facts then state them i.e. do not push the injection pressure above ***Bar. The clutch will need upgrading over 190BHP and 310Nm torque !

FACTS like these help people make their own rational decisions, not ones based on your ideals.

I am not going to get into some drawn out arguments on here. You do it your way, I'll do it mine. However, you asked me to put up some facts, so here is something to consider.

 

I am only going to quote you some generic numbers , as it would break my work contractual rules to quote specific numbers, but here goes:

PCM- There are different maps within the PCM to allow the engine to operate at -30

Gregers,

 

you are right I should acknowledge that in his last post Willie gave the advice as I suggested was the appropriate way to comment on a query post like this.

 

I still think that Willie is very 'black and white' in his view.... I mean VW authorise some of the tuners so what does that say about the whole situation ! :D

 

PING.....

Thoroughly enjoyed reading that debate guys :lol:

[zorgman]

i use a evry mod on my 99 tdi makes one hellava difference in power also chokes them behind me with a blake smoke screen but mine a homemade switchable, gleamed all the info off tdi forums where peops are getting 200bhp+ outa golf tdis (rabbits in states i think) it works by overfueling the pump and consists of a 0.005p resistor which is connected in pump delivery ecu, im not saying to do it but ill post the info here from site if you wanna play at your own risk as it can take your clutch out due to extra power or flange engine if not in good state of service etc.
