''piggyback Chip''

[kenty]

Hi all,

Please bear with me during this post.....I recently bought a 'piggy-back' chip with the intent of fitting it to my car. All it is, is a little resistor. This little resistor comes with fitting instructions. They say that I have to connect the 2 sides of the resistor to the 2 wires of the 'air intake temperature sensor'. I do not know where the 'air intake temp sensor is on a t-sport. Does anyone?

I have been asking around for a while now and people seem to think that it is incorporated into the MAF. Supposedly 2 of the wires that go into the MAF are the air intake temp sensor wires.....BUT WHICH ONES?

I realise I have been hasty rushing into buying this chip and that I should have been a little bit more prepared, but it seems that no-one has a clue where it is! ( I presume it has one? )

If anyone has any advice in fitting this chip or of the whereabouts of this illusive 'air intake temp sensor' it would be soooo helpful as I really am thinking that this chip cannot be fitted.

Has anyone fitted one of these 'piggyback's before or any ideas on any aspects of anything I've just said, please help me!

Thanks in advance people!

Cheers again! Ross

this sounds exactly the same as the "resistor" my mate bought for his ibiza

was a pain to install as he couldnt find the air intake manifold it went on

and

all it did was put to much air in to the engine as it trick the ecu

personally i wouldnt be putting that thing anywhere near my engine

sure people have said there damaging to your car on here before aswell :S

See the above/\

I hope that you did not pay too much for this "Chip"

These resistors are sold on E-bay as performance enhancing "chips" when in fact they are just very cheap resistors that can be bought from any electronics shop.

Fitting them across the MAF sensor fools it into thinking that not enough fuel is being delivered and results in overfuelling of the engine with subsequent potential for major damage.

Best advice is NOT TO FIT IT. They DO NOT live up to the advertising hype. :(

I am sure there will be others along here soon with the same advice and possibly a better technical description of how much rubbish these "Chips" are.

Sorry to dissapoint you :)

Think about how much you paid for it... think of the extra performance they told you it would give.. then ask yourself this...

Why hasn't EVERYONE bought one?

My advice is to put it in the bin and learn from your mistake, to get descent gains from a piggy back ECU you will need to spend a little more than you have and go for something like a Unichip.

sounds like the crap they're selling on eBay.

DO NOT FIT IT.

they trick the ecu into thinking either the air is colder, or there is more air going into the engine, so it causes the car to run lean, which aint good for the engine in the long run, not to mention it could bugger your cat up.

I'm presuming you like your car intact and working mate?! If so, take head of the advice above and bin it!!!

oh well....

i paid about £4.00 plus p&p and the description said it would give between 5-10bhp. Marketed as ''THE BEST BHP:COST RATIO IN THE WORLD!!!!!''

My 'chip' is now resting nicely in the bottom of my bin!

I guess that old ''If it sounds too good to be true'' saying isn' far wrong

Cheers for your help people!!!

Much appreciated!

It's the best place for it mate! Just glad you sought advice before actually fitting it though, could of been very costly indeed!
