Is It A Total Scam? 25Hp Plug In A Performance Chip?

I just cant believe it, but its so hard to resist at this price (which is what they are counting on...) But even if it adds no performance, and simply increases my fuel economy around town, it would be appreciated (even the wording says "average", meaning some could be none to negative). But the thinking part of me is jumping up and down yelling SCAM! SCAM! SCAM!

Has anybody tried these? or even know a "friend of a friend"....

Avoid is all I can say.

Most of the time its some cheap resistor rubbish. Some I guess advance the timing and makes people think that it's done something I guess.

Why would you risk it? It's seriously not worth mucking around with.

I have seen these things on Ebay before myself and was curious but having searched on here, decided SAU knows more than Ebay.

i would say it just f**ks with your fuel. turn it up and they reckon it gains, turn it down and use less fuel.

sounds bad either way.

Q: Hi I am interested how this chip works?

A: PROMAX X-CHIP connected directly to ECU sensors (MAF/MAP/IAT/O2) by playing with this sensors we can change ECU stock parameters.

Ummmmm..... So it tells the ECU lies about what is actually happening with the engine. Causing it to run leaner or richer than it was originally designed to. Sounds like a great idea

I love the bit where it says that it does not void the warranty. Imagine taking that back to the dealer and saying that the engine leaned out and you want a new one replaced under warranty

It is not a scam, but simply is a resistor which decreases the voltage signal of air intake in the AFM to the ECU, and so makes the car run a tad leaner and make a tad more power. Problem is the ECU will probably re-learn that it is there over time and not have any effect.

Either way, don't risk blowing up your ECU (or worse, engine) on one of these pieces of crap.

Go out and buy yourself an SAFCII ($400) or Apexi Neo ($600) and get it tuned properly ($300-$500). Does a similar thing (in theory), but professionally, with significantly more scope and complexity, and your tuner can perfectly tune your afrs to maximise power and fuel efficiency.

does anyone have a pic of a factory chip..... and where is it? Im wondering if a previous owner already did this...

thats exactly what happens. save yourself the money/hassle/problems and keep your money for a proper programmable ECU and do it properly the first time.

That's how all interceptor ECUs work. And, even with a standalone, you're basically doing the same thing (not lying to the ECU, but causing it to run richer/leaner than the engine was originally designed to).

The difference is that this thing isn't tuneable, so you're taking a massive punt on whether its too conservative (and does nothing for your engine) or too aggressive (and causes detonation).

Thats awesome , run them in series you will make heaps of power
