Performance Chip Question

[skimmilk]

I have a 1994 540i. I was looking online for a performance chip and I noticed a "high performance motronic chip" that increases the horsepower from 282 to "about 320" and the top speed to "170 MPH". It seems too good to be true. Is this all a bunch of crap? What should I know about performance chips??

if it sounds too good to be true, it probably is. if its a trusted performance company, the give it a shot, but if its so ebay type of crap-dont bother, all they do, as i heard, is raise the fuel:air ratio and give horrible fuel economy. so you decide.

I have a 95 540i and would really like to hear about this chip... It does sound to good to be true. Is there a website?

Please post the link here... I would like to check it out.

Thanks

It was on ebay but here's the link. I am very skeptical of anything that comes from ebay. The guy does have good feedback. The links below are for the ebay auction itself and the sellers website as well.

I dont know if it's for real or not. thanks for the feedback

Yeah, I have seen this seller with this chip many times. Good feedback but before I stick in a new chip I want to know more about it. Most of the time is is just dumping more fuel & air into the system and turning the fuel economy to crap... If you do go ahead with the purchase (and be the guinea pig) Please post back and let us know how it goes and if the claim is true..

This chip looks legit. I mean, it does mention that it replaces a factory component. The ones that raise your fuel/air ratio are simple resistors that plug into your MAF sensor.

http://www.dsylva-tech.ca/ EAT chips are imho the best around. Comming in second would be a Jim Conforti chip which can be bought at http://www.turnermotorsport.com/html/subca...34&subcat_id=74


for something as important as the computer chip of a car, i would go with something more reputable then some guy on ebay.

look into chips from dinan, they seem to have a great reputation

[Johnathan_Hess]

Well, the reputable places claim gains of 19 horsepower and 33 ft lbs of torque for a measily 250 dollars...

Seems far fetched, as well.

[The Deuce]

That kind of gain is theoretically possible, based on what the factory timing and A/F is. I've seen people pick up that much with a great dyno tune with stock V8's of other makes.

If you're thinking about getting a chip, I would recommend one that some of these guys posted or get one burned while you've got some dyno time. That way it would be optimized for your car and any of its quriks.
