Has anybody here bought this chip?

What do you guys think?

Jorge, if it was any good mate everyone would buy it . To get 25 bhp you would need to spend a lot of money, if you have the money get it supercharged or swap your car for either a is300 or toyota altezza

And it increases MPG!

Really? Don't think so somehow!

If you buy it let us know.

I echo what lexus loon is saying to squeeze an extra 5-10bhp from the IS200 will take more than a performance air filter and catback exhaust and both of these mods are worth more than the £20 being charged by this company for a "chip". infact a K&N panel air filter costs more than this "chip". I will say dont waste your money on this as it wont do anything to your IS. only way to make the IS200 quicker and rapid is Turbo or Supercharger which cost money or just do what i did and opt for the cheaper option and go for an IS300 or Altezza RS200. having come from a V6 ford Cougar with 170bhp the IS200 on paper performance figures wasnt quick enough for me so went for the bigger engined IS300 which packs more punch and torque and works out cheaper than buying a Turbo/Supercharge kit and performance exhaust upgrades just to get the IS200 to make roughly the same power/torque figures of the IS300.

Only way to find out if this £20 chip works is to ask the company for prof of before and after dyno results of IS200 making the claimed 25BHP and if they are happy to fit and dyno your car for results.

but would be more hassle than its worth.

there are only three ways to make power from a car:

1 Turbo or Supercharge (Evo,STi)

2. bigger cubic capacity (IS300, GS430)

3. higher revving using valve timing (AltezzaRS200, Celica VVTLi, Civic Type R's, Honda S2000's)

Pick your choice...

Its just a quids worth of variable resistor, not even a chip. It alters the reading the temp sensor gives the engine allowing it to run hotter.

If you wanted to try it yourself get a 100k pot from eBay and put it across the sensor. (lookup 100k potentiometer). You can try for yourself making your own adjustments just like the ad.

Be weary though - on very cold starts the mix will be slightly off as the car will think its a different temperature. It can also cause premature detonation.

Well i would like to try it, in a bmw 325i i had i bought a chip from dinan engineering they claimed an 18bhp increase i got my car strapped in a dyno and it actually gave me 15bhp, thats why iam looking if someone here has tested this.

Yes but Dinan is a well established BMW tuner with over 30years experience in tuning industry, they are just like Alpina company which Turbo charges the BMW's but this company you had in your thread I am not too sure of and if I recall; to chip a car is around £300 from Superchips in UK so £20 will be a no no from me. Apparantely EU/US chip tuning companies say Denso ECU codes found in Lexus are one of the if not the most complex ECU's to crack hence you dont see many guys on here chipping thier Lexus's on like Bosch written ECU's found in BM's, VW's, Audi's which are not so complex for Chip tuning companies to crack.

If you want a bit more responsivenes you can fit a short shifter for your gears, a lighter flywheel and a sport clutch but for out and out power and torque; well see my previous post.

This isn't a chip. It is a potentiometer. It isn't worded correctly. IATs work solely on resistance. What this does is allow you to change the resistance.

I suspected you would still want to try it either way, (an observation not a criticism) and there is no doubt in my mind it will change the performance in some way. That's why I suggested buy a pot from eBay. Same thing. Ask tuning wizard for a photo of the inside. You don't need to see values of components as its variable.

You still have to manually set it yourself so for the case of a quid, why not try one first? It just makes the engine think its cooler than it is when turned up so the fuel ratio is richer, and when turned down makes it leaner. (Hence the alleged mpg and performance - both aren't at the same time - its one or the other). That's the theory.

In reality by the time the ECU reads the false air temp reading, the other sensors will be advising there's too much fuel in the exhaust gasses and return the fuelling to normal, or at worst, throw up an engine management light if you have the adjustment to far. You will get small bursts - very small. Not noticeable in driving but specialist equipment can detect it so therefore they aren't lying though it could be argued they are mis-selling. As I say, the car will definitely feel different as this is going on because of the resistance change.

Thanks for explaining, maybe not worth it.
