Performance chip??
 

Has anybody installed one of these? If so, does it do what it states? Seems too good to be true for the money... or maybe I am too sceptical.

Performance Chip BMW M3 Z3 X5 1 3 5 6 7 8 Series 55+ HP - eBay Mod Chips, Performance Parts, Car Parts, Accessories, Cars, Bikes, Boats. (end time 09-Sep-09 10:55:49 AEST)

My guess is it modifies some sensor inputs to the DME, and I can say that it would void warranty on any engine or electronics problems. I wouldn't trust it myself.

If you are really curious about it ask them to send you the install instructions and I can look up the pin numbers at the DME and see what signals it is modifying.

Sounds like another recent post.

Rolling my eyes....really? I've got some blinker fluid for you to buy if your interested.

Selling my muffler bearings if anyone is interested!~

If I change from halogen bulb fluid to xenon fluid, do the blinkers get brighter, or just change colors...? :rofl:

Thank you m5james for the smart ar#e response. That was why I came to this site because I thought there was less of the "stereotype" BMW driver. Looks like I was wrong.

Dude, I'm new here and I can tell you that this site is full of very helpful people who will answer intelligent questions in kind.

That said, did you really think you weren't going to get some smart-alecky answers when you ask about a $20 part that will "magically" give you 55+ horsepower? You may as well have gone to your green grocer with a handful of beans and ask him if they'll really grow into a beanstalk...

so whos going to try this Chip?

You better off go with this one ...Many ppl over www.E60.net had done and love it.It's just like turbo tuner for turbocharged cars.(split second turbo tuner)
For me i got Dinnan software done to mine.:thumbup:
Sprint Booster Testimonials - www.SprintBoosterSales.com

Thanks for those trying to be helpful. I do appreciate that there are a lot of genuine people here.

Weasel raises a great point about warranty, as I still have warranty would need to think through. For those that took the time to look at feedback from the seller (rather than just making a joke out of my original question), there are a number saying that it made a great difference on other vehicles - as well as some who said it didn't, hence my reason for asking re the X5. Also thanks to mrbmwx5, there are certainly some strong supporters for the sprint booster. So even though it is more expensive, sounds like a better piece of kit.

These types of items are usually a simple resistor that replaces a certain sensor's feedback. For example, in motorcycling world, most of the new bikes have a timing retard built into them that usually only works in lower gears ( to comply with noise/pollution regulations), so a 'timing retard eliminator' or a TRE can be installed that takes care of that problem. The TRE is either a resistor or simply a short circuit to ground, depending on the bike/etc.

One of the feedbacks on this guy's ebay account says 'I can't find the oxygen sensor'... this kinda tells me that this product perhaps replaces the oxygen sensor's resistance with a value that shows either too much oxygen (causing ECU to add more gas to the mixture to recover), or too little oxygen (causing ECU to reduce the gas to mixture) ... niether of the situations are desirable in the long run.

Also, when someone's english is as poor as this seller's, I usually start to doubt their technical knowledge. (Anyone detailed enough to come up with a GOOD product, will be detailed enough to make sure their ebay ad is worded properly.)

I would pass on this if I were you.

Come on Mozzie... We're just kidding with you. I'm sure no one means anything by their comments.

To your question, if you want any more performance, look up www.Dinancars.com. At least anything you add to your X will not void the warranty. ANYTHING ELSE runs the risk of screwing up your X for you.

There are supporters and non-supporters of the Sprint Booster. My only caution would be that you appear to be comparing it to an eBay device that claims to increase power. Whether those devices on eBay do that or not, the Sprint Booster doesn't increase power, or claim to. It changes the response of the gas pedal, that's it.

Retard eliminator, hmmm. I could have used that many times in my life!!! :rofl:

:iagree:

Thanks. All makes sense. Really appreciate the advice!!

I know you remember the answer to this
famous line..."If it's sounds too good to be true".......:rofl:

You also need to be wary of feedback shown on sellers because some sellers have been known to plant positive feedback about their service and products. I always try to check the seller out with a search of their company.

I have gotten some real deals on ebay, but also had one that the product wasn't good and they had great reviews. Returned it 3 times for replacement and then gave up and got my money back.

Stereotype - so should I assume Aussies are sensitive and can't take a joke? I also own a Chevy Blazer, Suzuki TL1000R and a 740iL - does that also make me white trash, a biker punk and a guy who's well off? All I'm trying to say that, even in your own words, if its too good to be true, then it usually is. If you want performance mods, get software from someone like www.powerchipgroup.au or $$Dinan$$.

Now don't quote me on this, but I believe it'll change your bulbs from a nice amber to something more a tacky red and flash like a strobelight, similar to all those cool Honda ricerockets out there using LED's w/o resistors. Consult w/ Pentosins website for specific fluids :P

When I was an F14 PC in the Navy, we'd mess w/ new recruits w/ stuff like this. Obviously muffler bearings wouldn't pass, but we'd get em w/ blinker fluid and "go get the keys for plane 11"....oh the pranks we played.

Yeah, when the spam calls for car warranty contracts kept bugging me I tried getting coverage on my 2004 camaro, but they couldn't seem to find it in there system? They told me I must mean cavalier as they show that. I asked if the cavalier came with a V8 and they responded "I think so".... idiots.

We got one of the porters when he was doing an oil change on his old chevy truck. When he was under the truck I unplugged the fuel pump relay when he wasn't looking. He kept trying to start it with no luck :D. So when he wasn't looking a few minutes later I put it back in and grabbed the smallest hammer I could find. When he came back by the truck I gently tapped on the front corner of the valve cover and told him to try it... it cranked right up naturally. He was dumbfounded and asked what that did, I told him his "valve pressure sensor" was stuck and he must have a clogged "fluid coagulator" that to have happened... You know he spent hours on the phone with autozone/napa/advanced auto/o-reillys trying to find those parts?!? Still never told him better and he's waiting to see if it happens again with the next oil change. (If I'm there it will :D:D:D)

Good god! I just visited www.powerchipgroup.com and for the low low price of $840, I can get a whole 10hp and 10ft/lb of torque! Not worth the time, effort, money and risk of imploding my engine. I'd rather save my coin and buy a BBK or an aero kit or a great set of rims or .....

why?
 

a "performance chip" ..for a x5 3.0i........a "performance..chip"
..... for a ....... 3.0i...."ebay" :tsk:

:bustingup

I'm not sure which motor you're referring to, but I see $640 w/ a minimum of 14hp and 12ft lbs of torque on a stock motor, and upwards of 16hp and 19ft lbs of torque (i'm guessing w/ intake and exhaust). I've never used Powerchip on either my 7 or my X, but they were VERY popular in the M5 groups when I had mine. I personally wouldn't buy just software, i'd also do intake (cone filter/tubing manifold swap) and exhaust mods beforehand, making the software a better bang for the buck.

$$Dinan$$ isn't much better for just getting software alone either for $399. They only get 9hp and 11ft lbs of torque on a notoriously conservative tune compared to others.
