Chiptuning in E39 M5 with engine at 160.000km (100.000miles)
Hello, i asking myself if it would be bad for my engine if i let my car chiptuned. Engin have now 160.000kms (100.000miles).
People advised me to go to 'Power-Plus' (PowerPlus.be - The best choice to be in front), these people from Power-Plus tell me that this will not cause any negative effect to my engine but that will tell probably each tuner. I will have a profit of 30hp and 47NM torque. The car will go before and after the chiptuning on a rolling road.
I want let this do, but only if I am certain that my engin will have the same life span then without chip.
Someone experience?
Thanks!
First off, you will see no such gain in BHP or Torque. This is marketing folly and large gains are not possible with remapping, unless you have forced induction to start with. You will likely only see a 5 - 10 BHP rise.
Having said that, I had mine remapped at around 120,000 miles and I only wish I'd done it sooner. This engine is good for over 600BHP in stock form so you certainly will not damage it. The re-map sharpens up the throttle response and seems to give more urgency across the rev range. The car constantly cries out to be revved and pushed harder than it ever did before. It even sounds a little better as the timing is advanced slightly - the exhaust note gets a bit crisper and less woofley. The real dyno will not show you a massive gain, but your butt dyno will be off the scale. Do it!

Thanks for your reaction!
So why should i put a chip? What you explain me seems to be the same as pushing on the sport button...
I don't want that the chip changes my throttle response, i have a button for that.
Is there really a difference except the throttle response?
What means 'revved'?

But imagine if you had Sport Button on top of the Sport Button....
My thoughts are the same as 100%COCOA above.
I recently installed Supersprint Headers, followed 10 days later by Shark/Conforti software.
I haven't dyno'd my car, but the "new" driving experience is as described by 100%COCOA.
Also, I highly recommend the inexpensive E60 short shift upgrade.
I may do lightened/underdrive pulleys next, then mufflers (not too loud) and then call it quits for mods.
It is difficult to describe, but the ECU tuning does more than pressing the sport button. There is more to throttle remapping with the engine software than just making the throttle bodies open wider for a given amount of pedal movement. There are real gains in torque, HP and driveability, but not dramatic. It will be more satisfying to drive is all I can say. As long as the software don't alter the peak rpm limiter (or don't often exceed the stock rpm limit if the limiter is removed), there shouldn't be any significant added wear or risk of damage to the engine. Increasing the rev limits (which is DIFFERENT from removing the top speed governor) just a couple hundred rpm GREATLY increases the stress levels on certain engine components, so I advise not doing that. The option to increase the rpm limiter or not should be present on all good ECU aftermarket software.

"Is it the sounds that make a BMW a BMW? A BMW is designed to be heard, felt, experienced. So our engines sing. Our steering talks back. And we insist on offering manual transmissions in nearly all our models for drivers who crave them. The result is an almost telepathic oneness with the car. Just as surely as you can hear a BMW, a BMW hears you."

with the exception of The Shark Injector, ESS/powerchip both offer the option to NOT raise the revlimit.
I will ALWAYS shift at ~6700-6800rpm every time under WOT just to be safe, shark or no shark.

Hey Andy!
are the Supersprint Headers the money worth? Big difference?
From which E60 do you recommend the shift upgrade? The E60 M5 is a 7-gear...
What is not expensive? Does it fit in a E39 M5? Modifications to do?

OK thanks,
so chiptuning yes but without increasing the RPM...
