chips

its not all about top end power though, area under the curve is whats important.

Exactly, and that's where chips are useful, however this discussion is about a chip that claims to add 21 bhp to a standard M20B25.

My M5 gained nearly 25 BHP through the rev range from a chip and 10 bhp at peak.

Another M5 which came in yesterday gained only 3 bhp with the same chip.

The relationship between the condition of an engine and how well a chip upgrade is going to work is very very clear from the number of older cars that I have done.

I have remapped quite a few E46 M54's and we always get in excess of 10 bhp on them just from altering certain parameters. Consistent result on low mileage well taken care of cars.

21bhp from a chip is a total piss take on an M20 though. My dyno is available for free to test this!

agreen,

you can take your car to Phil Crouch @ CPC and Bexley Motorworks in Kent, A-Tech in Kent to get a health check done and make sure everything is working as well as it possibly can.

Well, this goes to prove that a decent chip change can indeed give a gain, obviously dependent on engine condition.

I'd be happy to take you up on your generous offer of a free dyno test, unfortunately I currently only have an M30B35 in an E34 to subject to such a test having sold my 325i. Nevertheless, plenty of satisfied buyers of both M20B25 and M30B35 chips providing positive feedback over a period of a year confirm they work well.

sal where are you could you chip my 318is ? and dyno it might be worth a drive down to you where evere you are asap

[EndaW]

Speedtouch does indeed offer some decent chips, reason we know this is that his 325i chip is a copy of ch|ppeduk`s 325i chip.

[Speedtouch]

No it's not! Where did you get this misinformation from, might I ask?

[EndaW]

I personally read the file in your code, it has ch|ppeduk in the last line 042F0 of the binary code.
How do you write your own software ? Whats your timing advance at 1100rpm and 20% load on your 325i file ?
Its no big deal, maybe you buy this software through someone else then simply copy and sell on ebay, either way the software isnt copywrite protected so no laws broken, just morally bad.

[EndaW]

They essentially increase power by extending the upper rev limit from the rather conservative 6,250rpm that the standard BMW program givesThis is not the case, by 6250rpm the cam has done its job and increasing rpm only aides drivability under hard driving conditions but will NOT give extra power, also removing flat spots caused by the (often unnecessary) emissions sections of the standard program thus significantly increasing throttle response and making the car feel more 'torquey' at most road speeds Again not correct, this is the case in modern cars but back in the day emmisions were not so important as we had 4 and 5 star petrol with greater limits on emmisions, the flat spots were to do with the mapping for multiple grade fuels availible throughout Asia, USA and Europe. Thus, there is less hesitancy, giving improved acceleration and arguably making the car safer for overtaking maneouvres, plus a higher top speed should you ever need/want it. In general, they give you more in reserve.

Standard isn't bad by any means, but there is always room for improvement, and a *good* chip provides this.

Power on this car is achieved with ignition advance and fuel, providing a sharper throttle feel, this can be had by adding upto 6 degree advance at low-mid rpm through too 1 degree at higher rpm range and across the rpm/throttle band.
Fuel adjusted from 2500rpm will also give a sweeter delivery.
In truth, there isnt much to map in the 320i/325i but on the 318iS its a totally different story.

Since I haven't personally sold you a chip, EndaW, how can you possibly ascertain the one you read the file of is one of mine?!

Explained in pm.

[M5pilot]

Guys, I am more than willing to test the chips out and I will not charge for dyno time.

All I need is 2 decent cars and we can see who's chips work and who's don't.

Ant I know it more than up for it, are the others?

[EndaW]

I will get a chip over to you but problem is, there is more chance of me winning the lottery (and I dont even play it) than getting 21hp from a chip on the 325i.

[Speedtouch]

I would be gladly willing to supply one of each M20B25 and M30B35 chips to test - customer feedback has been good...

Cheers,

[EndaW]

Customer feedback will be good, these cars are great to chip, the difference in feel of the car is superb from idle through max rpm.
Its not all about power, there are cars where we actually lower final power output to give better feel which sounds odd but is the case on quite a few cars.

[M5pilot]

If the final power figure is dropping then your obviously doing something wrong.
