fred_ 166 Report post Posted October 31, 2016 (edited) Evening Bimmersport, I've waited a few weeks to post this to ensure the tune worked out any adaptations and allow for adequate driving situations. Some context.... Last month my beloved E46 was due for its annual checkup at HellBM. While I was there, Ray informed he'd finished developing a custom tune for the E46 M3 and asked if I would be interested. Given he was 18kw clear at the top of our recent dyno day leaderboard, how could I say no! First things first, Ray is the best in the business when it comes to dealing with E46 M3's. The fact he has 5 x S54 powered (from last count) vehicles of his own is a testament to this. And if Ray isn't under the bonnet, rest assured his knowledgable son Sam will be giving your pride and joy a good once over while it's up on the hoist. Now... The tune. Prior to installing this, I already had an altered map which Tom (M3 Power) had installed, providing a significant gain over stock figures (I'm 'A2K' in the board above). As part of this tune, I requested Ray do the following: - Top Speed Limiter Removed - Exhaust burble on overrun - Shift lights (for a 6-speed manual) - M Track Mode (soon to be coded) Even though my car had already been toy'd with, after 800kms of driving I've felt a significant improvement. I've bullet-pointed my key takeaways so far: The low-mid range power and torque increase was instantly noticeable No longer do I feel a sluggish response when cruising around town in a higher gear Response through the rev range is much stronger and linear all the way to red line Throttle response has remained smooth and "sport" mode is highly enjoyable and no longer jerky Fuel economy has remained consistent, if not slightly improved Since getting the tune, I've also attended a track day at Pukekohe. While I'm no Lewis Hamilton, I was able to improve my previous personal best by almost 3 seconds a lap (based on my Track Addict app) and was pulling away from friends on the back straight which I had previously been neck-and-neck with on my last outing. The improved throttle response gave me a lot more confidence coming out of corners and despite my amateur driving ability, I certainly felt faster! I will be sure to get another Dyno run shortly to prove it's not just my butt talking! Ray has since told me this tune is now available to Bimmersport members and I highly recommend it based on my experience. Thanks again to the team at HellBM! Any questions, please feel free to ask. Cheers Alex A recent pic of the car: Edited October 31, 2016 by leebske 2 Quote Share this post Link to post Share on other sites

No, but I know Gavin does custom tunes and tunes all the bmw race cars. The man is a genius. 1 Quote Share this post Link to post Share on other sites
m325i 709 Report post Posted November 1, 2016 +1 for the over-run clip please. Very keen on this, will speak to Ray... Cheers. Quote Share this post Link to post Share on other sites
Neal 543 Report post Posted November 2, 2016 Watching with interest. My car seems to be going down in power. first hub dyno at 48,000 km saw 230kw at hubs. Car was one of the quicker M3s I'd tried going by butt dyno at time of purchase . Second Hub dyno at 90,000km saw 210kw at hubs Third roller dyno engine run at 122,000 saw 183kw at tyres (Running Mobil blended 98 which causes pinking on the M3) Running SMG so thinking about csl software for subframe longevity and restoring power. 1 Quote Share this post Link to post Share on other sites
BreakMyWindow 1874 Report post Posted November 3, 2016 That's a fair few escaped horses. Sounds like the 2 hub dyno runs were done in dissimilar environments. Roller dynos always seem to read lower than hubs. 1 Quote Share this post Link to post Share on other sites
Michael. 2313 Report post Posted March 7, 2017 Bringing this thread back as it's interesting So what does a good used, stock M3 make on a rolling road dyno these days? Looking at those figures above give or take 5 rwkw suggests 190rwkw is a decent mark for a looked after E46 M3 in stock form.. Quote Share this post Link to post Share on other sites
Funkyflynz 151 Report post Posted March 30, 2017 Mate, any chance of that burble over-run clip? i assume this is a semi backfire/crackle on deceleration? Quote Share this post Link to post Share on other sites
