Evosport Software Claims (Stage 2)

08E60M5 · 11th December 2007, 17:32

I just received this e-mail today, but I do not know if someone posted on this already. Most other performance chips are claiming these same numbers. How much will it really change throttle response. Is it worth it just to remove the CEL from the non existent pre-cats?

BTW. I am the son of the "other M5 owner" from ///Marshall's post on plugging the stock air-box over at RPI (they are awesome by the way). I have clips of our M5 (evo headers & pulley, RPI scoops & BMC filters) and ///Marshall's M6 on the dyno, in addition to the RPI M5 (Eloy's) Dixis Titanium Exhaust.

Welcome with your first post! Sorry but I've never been good
with names.

It's difficult to say whether it's worth the price. I think you can
safely say that what you get is the delimiter, increase in rpm,
CEL fix. Throttle response and minor (if any) hp/tq gains would
be icing. For us SoCal folks you also don't need to worry about
sending your ECU in the mail for a reflash.

I just placed my order for the 91 octane version.

They have different octane versions???

East Coast = 93, West Coast = 91

Ah, thanks. To try to answer your questions, I've had Stage II for a few weeks but only a few hundred miles. Hard to gauge any 'improvement in throttle response" with any mod, IMO. Very subjective, but as Marshall stated, it does increase the rev limiter, removes the speed limiter, and important for many (esp for purposes of emissions testing) eliminates the SES light by deactivating the rear 02 sensors. Is all this 'worth' it? Only you and your wallet can make that decision.

I was considering AA's Stage II S/W, but 1) it's more expensive, 2) Powerchip's version is supposedly programmed specifically for use with Evo's headers. What does that mean exactly? Dunno, but I think it's generally a good idea to match mods with the same manufacturer as much as possible to prevent cancelling out gains.

I´´m considering, evosport headers and pulleys and bmc filters and air scoops for my 08 european vers m5, we dont have charcoal filters in.. from fabric,

and we can run 95,97 og 98 octane over here... how about the chip, it must be very different from your US models...

How come an M3 software upgrade is about $500 on ours is $1000 more any specific reason besides the fact that the cars cost more?

Actually, it's pretty similar I believe.

Europe uses the RON (Research Octane Test) numbers for their octane rating. The US uses PON (Pump Octane Test), which is the average of RON and MON (Minimum Octane Test).

95 RON = 91 PON
97 RON = 93 PON
98 RON = 94 PON

Sure wish Turner or someone would sell a Shark Injector type software upgrade. I've considered the AA product, too much of a hassle sending the CPU in for update every time BMW updates the OS.
