Performance Question

[newbimmerdriver]

I am just wondering...

I know I have said this alot, all my car has is cold air intake. Should i get exhaust next or should i dget a performance chip. Also can someone please explain to me what exactly a chip does and where i should get one from. Also what the hell does exhaust do for me, besides make me loud??????

You can get a chip from turnermotorsports.com or bavauto.com. It reprograms the computer of the car, optimizing settings, removes your governor (so your speed isn't limited at 155), raises your redline 250rpm, and adds a decent amount of hp and torque. Essentially it's an out-of-the-box "tuning". A downside is a chip hurts your miles-per-gallon a bit, as its dumping fuel into the engine.

Exhaust will also add some hp and torque to your car, though it's more for top end. By installing an aftermarket exhaust (most) open it up a bit more, so you lose back pressure and thus speed off the line. Though it makes your car sound badass, and you have a bit more power overall.

I've done a chip so far, and I'm looking at an exhaust now. I would personally do a chip first, then exhaust pretty soon after. Your choice though.

Cheers

So if I do get this chip I am going to have to always fill up with 92 ocatane gas. Why do i have to do this? And what is the maximum speed on my car now 155???

Adding a chip optimizes the air/fuel mixture, by utilizing premium fuel. You get all of what Komodo mentioned: better horsepower and torque, a higher redline, and your car won't stop accelerating at 120-some-odd miles an hour.

Your car is electronically limited by the car's computer so you can't accelerate to 150 miles an hour. This is for safety. Obviously.

Yes, you will have to use premium fuel because that's what the chip is programming your car for -- premium fuel. However, you'll get better gas mileage with a chip and premium fuel versus just using premium fuel.

It won't offset the entire cost of purchasing 91+ octane, but it would help.

In short: get a chip.

Thank you very much for all of the input. I will be looking around for this chip and still on the look for exhaust. I still dont get this does my car not go past 120 or
150??

[93 325i]

The governor is at something like 126MPH..can our cars do 155 with the governor removed? I doubt it..unless you got some serious mods

u drive a bimmer.. chip or not!! u should put high octane in it!!

[Johnathan_Hess]

I'm guessing that a 1993 325i's theoretical top speed is 150 miles an hour plus, but I doubt the stock engine could push it much faster than 135-140.

A great deal of the people on this board own a E36, so one of 'em should be able to verify the top speed of a chipped 325i.

But, yeah. When you chip it, you should get between 10-15 horsepower, you can rev it higher, and you can can go faster than 128 miles an hour.

how much do chips go for?

the highest it will go is 145mph. at that time (of course in 5th gear) the rpms are at 6600. hence at 145 you simply run out of gears. you might be able to go a little quicker with a 6-speed tranny or a different gear ratio.


conserning the chip question:
a chip advances the ignition times. the times are regulated by the software that is on the chip. once you install a performance chip you are basically "reprogramming" your car. due to the advanced timing you have to use better gas (difference in combustion time, i think)
further the software takes off the governor, which is 129mph in stock US models and some will give you a couple hundred rpms by bumping up the rev-limiter.
all in all a chip will give you much more when it comes to performance than an exhaust.
but... if you want it to SOUND fast, then go for the catback -> 50 more butt-dyno HPs
if you really want some performance out of exhaust system mods you have to do the whole 9 yards... exhaust headers, cat deletion or high-flow cat and catback

Thanks for everyones input! I have one last question...can i go ahead and get a chip without and exhaust right now...whats your thoughts on this...

[robbins6103]

A basic rule of thumb when tuning cars is to get the chip last, the reason for this so you have it programmed specifically for your ride. Do some more research and find a place that will program a chip just for you. A chip from Turner or BavAuto would be sufficient, but if you really want to get the most out of your mods, take my advice.

Thanks alot and i might take you up on that, but im not looking to spend that much right now...thanks

[325is1994]

i had a chip and removed it cause my gas mileage went to hell in a handbag
