Performance resistor????

[zeus4604]

Hi ive just purchased a '''performance resistor''' off e-bay (shoudlve went to maplins yes i know mugg), i know how it works and all the rest of it but which two wire slots do i clip the legs into there is five to choose from in the air mass sensor. It says u clip them into the two slots and leave it disconnected. Any ideas anyone?

my mistake, ive been informed i need to put it on my coolant temp sensor, any ideas where it would be, cheers

I wouldn't bother with it if I was you.

If it's what I think it is, it is only a resistor that fools the ecu into thinking that your car is on cold start, hence over fueling, stalling, smoking, misfire codes, bore wash and ultimately, a very dead engine.

Total waste of time.

dont do it....

I agree with RON, if it was any good the car makers would would alter the settings accordingly.

More snake oil - here is another one on ebay, 5-20 BHP improvement for 99p + P&P

too late, ive fitted it and the car goes like a rocket, so yes it does work and god knows what long term effect it will have (it still keeps the fuel injection into the engine within the factory limits they dont set it this high because of fuel economy, economy versus power your choice), but hey you gotta try. ive tried it, now ill remove it, it was only a short term solution to what everyone said i had an air mass sensor problem, lack of power, acceleration etc, so i tried this to see if it would improve and boy oh boy yes it has! my car is getting diagnostic checked next week to check my MAS but looking at this i wander if its my coolent temp sensor this is where ive connected the resistor and the performance is very responsive all the problems b4 have gone while this is fitted.

Interesting to hear an opinion from someone who's actually tried one. The theory is sound in that cars today run at around 10% below optimum fueling for reasons of economy and emissions.
Mercedes used to actually do something similar which was controlled by the ecu in cars built upto about 1993. At full throttle the ecu would richen the mixture for maximum power which is why the first 6 litre v12s produced 400 plus bhp while the later ones without "full load enrichment" as they called it produced something like 380 bhp.
The thing to do would be to find someone who could put together a circuit so as to allow the richer mixture only when required. All the benefits and none of the drawbacks.
Off to Maplins now.

ive just bin on another test run to york along the A19 and the outta ring road, no hesitancy, no flat spots and great acceleration, my fuel needle hasnt even moved so i may just keep the thing fitted instead, as i said earlier i was having symptoms of my MAS/MAF being faulty with this resistor my car runs better than before, and guess what its all true, i dont sell these so why blag, go and try! a 60p resister fitted to the coolent temp sensor(loom end) hey presto no problems anymore or and expensive MAS/MAF i know what i'd choose. Anyone wanting to try one they have 2 legs on the resistor insert a leg each into the two wire slots on the coolent temp sensor loom, dont let the legs touch each other and tape it in place, do not connect the sensor back up, then test run. Wear ur seatbelt!!!!

Waste of money mate. You'll pay in the long run. Get it fixed properly instead of snakeoil solutions.

 

[Ron Palfrey]

I am delighted that it seems to have done what you required of it.

What was the value of the ressistor please, I would like to do some test. thanks.

Probably about 10p (lol)

Probably about 10p (lol)

OK, very good, I left myself wide open for that:???: I can wait:evil:

I would be interested in learning the resistance value also.

Suppose you could drop on a multimeter and get a resistance range from cold to hot ? Then dashmount a variable resistor and turn it up when more power is required...

That's exactly what I was thinking.
Can any one tell me the ressistance in ohms.

This has broken my heart to buy one from Ebay for 99p when I have more than 2 million ressistors in stock. What I will do is to wire up a pot with a ressistor in serries so that no damage can be done as soon as I know the nominal value.

This 'snake oil' sure has got your attention!

However, I too am sceptical of the claimed benefits and wary of the consequences.

 

[d4hwt]

hmmm,
i wonder if zeus sells these "go faster resistors" on e-bay....he seems to have got at least 1 sale so far anyway.....
if ya want a faster car then go buy a faster car....sounds like a recipe for disaster or a fire hazard...that's my 2p worth..i'll get back in my box now...

 

[davidsl500]

hmmm,
..i'll get back in my box now...

Good Idea ...lol

granted, the standard use of this resistor as a permanent susbstitution is probably not a good idea I would agree. As for causing fires - only if you havent got a clue what you are doing in which case leave well alone!

Malcolm and I have been refining the idea behind the scenes and have come up with a much more sensible useage. More later !

Well I tried it this morning~~~~Took off like a rocket, so much power I broke the seat back, will report back shortly.
