now let me ask you guys this do these things realy make a differance in every day driving or am I just tossing the money out the door? A buddie of my had a BS chevy s10 and put a chip in it and all it did was make the check engine light come on I know that is a realy bad comparison but cash is limited so I realy don't want to waste my money!


And realy what are the differances in the chip Bav wants $250.00 for a chip and this one on ebay eBay Motors: 91-92 BMW E36 325i/is E34 525 Ecu #405 Performance Chip (item 250022305224 end time Aug-31-06 19:00:00 PDT)
goes for $44.00 bucks and claims to give about the same power and tourge are you paying for the name or what???

ive never tried any of the other chips, i have the TMS chip and it works awesomely, you can def feel a difference just dont expect your car to turn into a rocket or something, i never had any problems with the TMS chip, alot of people prefer the dinan cuz its authorized by BMW and it wont void your warranty, as for ebay...well you get what you pay for

i'm pretty sure that all those chips do is change ur air-fuel mixture which is a no-no the bmw computer is very complicated and ur paying for a chip that accurately adjusts EVERYTHING that needs to be done.

just trust our insight and know those e-bay chips are crap. like everything else in life you get what u pay for. U know anything you can buy that gives you 20 hp for $40? i think not

Agreed! The key to a good tuning chip is balance. Timing curve, timing advance, fuel curve, injector pulse width, throttle mapping on later models, etc... The cheaper the chip, the less research has gone into its effects and how it will interact with your driving style, not to mention how it will affect your engine! I personally prefer Dinan as rej mentioned, due simply to the fact that it is factory approved and BMW won't void any warranties due to its use. That to me says it is a quality piece and well worth the asking price. Keep looking on Ebay though, alot of times there are used Dinan chips on there for $50-$75! I have one in my M20 325i and it does make a considerable difference especially in top end pull to redline. Worth the dough!
