cheapo chips

[dobski]

hi,

has anyone tried the tdi performance chips that are for sale on ebay they repour to achive an extra 38bhp and 70 nms of torque is this bull or do they work all this for about 50 quid. thanks

complete and utter tripe mate, take a look at the following:

draw your own conclusion, but anybody on here who knows anything about 'proper' remaps would not touch these with a barge pole

I've got one on my Touran 1.9. Its improved economy by over 10 mpg and seems smoother. Yes a remap would be far better but I can't afford £500 for one. Horses for courses it seems.

Only superchips retail their chips for £511 which I agree is a lot of money. Otherwise, most remaps are in the range of 250 - 300 pounds which i think is very reasonable considering the extra enjoyment you get from you car..

Fourbears, im sure that cheap chip will work out alot more expensive for you in the long-run as Im sure its not doing any good for you car..

thanks for the help i dont think ill bother with them then sounds like youre getting exactly what your paying for rammel and problems.

hey, first of all after reading eshrules comments on tuning boxes it appears to me that it is quite in keeping with the rest of his posts lol
It depends whether ur car is a tdi ..injector pump engine or a pd unit injector engine .secondly if the car is an older tdi ie the unit injector engine ..it is attached to the quantity adjuster..therefore it interprets the ecu signal to the adjuster and reprograms the signal so that the car injects slightly more fuel. these systems are mostly adjustable so its fair to gain the performance u want u can adjust it to suit..futher more it can be adjusted to prevent smoke..which to be honest doesnt really affect the vw engines provided its not severly over fueled. Eshrules also makes the point that mpg is lower ..nonsense ! with the added performance the motor is not being worked as hard to gain the level of performance u had before chipping it ..provided u dont use ur right foot too much lol
and one last crucial point ..a tuning box should in no way affect the engine temperature ..the pd resistor type boxes is across the fuel temperature sensor not the coolant temp ..the fact that eshrules friend with a 110 hp engine had an over heat ..has nothing to do with the tuning box..theres no feasible way that could happen ..its more than likely due to lack of care of the car. the ecu fuctions are retained as far as the management is concerned the tuning box shouls in no way ..NO WAY ..cause overheating problems !
if ya need any more help give me a shout lol and ill help ya pick one ..there are lots of excellent ones ..depends on ur engine of course..provided its an injector pump engine the prices shouldnt be so bad ..as for pd to get good quality systems .a little more maybe !
cheers chris

thanks for your help i have the non pd 110bhp tdi 1.9 2001 golf engine code asv 1j with the ten pin pump connector.

this is not an argumentative forum and as such, i welcome your input, perhaps you could formalise your opinion and post it on the sticky thread to advise the 'alternative' tdi engines. i am obviously looking at the matter through jaded eyes.

one thing i got told, which is a general rule of thumb for everything, is you get what you pay for. if you expect a £30 resistor to do the job of a remap without any damage to your car, you are under a sad illusion. moreover, if you are messing around with the fuelling of the car, of course youu will affect MPG, no matter how heavy your right foot is, you are increasing the amount of fuel passing through the engine, some of which will be unburnt, more so than normal. uburnt fuel is what causes your smoke.

if you put too much unburnt fuel through your system (eg increase the fuel/air mix too much) .... i cannot belive for a second that could be good for your car engine as always, it is each to your own, but personally, i would stear clear. remaps and official chips come with warranties and gurantees, because they know what they're doing. cheap resistors of ebay do not....

ok ok ,
first off ..cheap resistors dont apply here becuase this man has a tdi engine .. NON PD . the tuning box in this case alters the fueling via the quantity adjuster. the original tdi engines are extremly underfuel so therefore a quality tuning box not also increases the fuel injection quantity but also advances injection timing via the ecu ..in effect the fuel..although there is more of it has longer to burn in the combustion stroke ..reducing the amount of unburnt fuel hense reducing black smoke.
a remap is nothing more than a basic changing of the ecu fueling characteristics however if it more specific to one cars ecu. good tuning boxes do the same thing however they are harder to perfect. i dont think the fella should completly disband the idea ..if he trys to look for a psi power box ..i believe he will be completly satisfied!

just 2 points...

if the old tdis are 'underfueled' you will affect MPG therfore by introducing more fuel into the combustion chamber. either way you look at it, your burning more fuel, less mileage to the gallon.

secondly, i disagree with the remap point, my friend who will be doing mine for me remaps american and power trucks alike, it isnt just the fuel mixture they tinker with, if it was as easy as altering the fuel mix, i doubt there would be anybody making any money from it.

as i've said, its down to personal preference, i fail to see how spending £40/50 on a 'tuning' box off eBay can improve your bhp, your mpg and still not affect the car's mechanics.

i'll try to get a techies opinion on this, would be nice to have a definitive opinion
