ESS tune options for track
I had the ESS tune for a while, way before I started tracking, and now that I'm tracking more, I wonder if some of the previous options I had should be changed:
- 8600 rpm: although the extra 300 rpm is nice, for me i felt it's quite easy to go over 8300 rpm on the track and create more stress on the engine - servotronic: the steering becomes heavier with speed, but I'm wondering if the factory servotronic setting is more accurate for the track - reprogrammed throttle response: again, wondering if the factory throttle response is more accurate for the track I'm not sure if these are just things that won't make a difference after you get used to them, but I was hoping to hear some of your opinions, thank you! |

ESS is a great tuning choice
8600rpm is 200rpm more than stock. Stock is 8400. Max power is 8300. Cars have shown they are faster when shifted at 8600 vs 8400, however, it is obviously higher rpm means higher stress. What many opt to do there is keep the limit to 8600rpm and only use the extra revs when needed I can't really comment on servotronic. I don't think either option will affect anything. I personally ask my tunes to have fully linear throttles. That's what I like, it is more precise. |

I got the ESS tune and track with it, but decided to stick with stock throttle response, servotronic, and RPM limit. Didn't see a need to adjust those settings, and I use sport mode steering + standard throttle response on track anyways. Disabled cold start though.

It might be useful to graph the thrust curve for your car and assess if the extra few hundred RPM are even necessary. I agree that short-shifting at the original redline is probably the safest approach, leaving the extra RPM for a track where you can really maximize it.
As far as steering and throttle, that's personal preference, but the pragmatist in me says you should go for linear response for the best control/feel. I have never liked touchy throttles or overboosted steering in any car I've owned -- I always run them in normal mode.

Interesting (If you are being serious). I can never tell. Servo I've always kept unchanged as well as throttle. However that being said, sport throttle may play a major facet toward heel toe. In normal throttle, I've always found it unnecessarily exaggerated a push you need to give throttle in order to get a decent blip with side of your foot.

No, in all seriousness I agree. I've never played around with the Servo steering and always left throttle on normal. If I remember correctly your E90 was DCT? |

Get an auto-blip so you don't have to heel-toe. Yes, my E90 was DCT.

I understand that being able to heel-toe is a rare skill that people want to brag about, but the auto-blip makes it so you have one less thing to worry about on the track. You're not relinquishing much control, IMO. I would encourage you to go drive an M3 that has it, or another car with built-in rev-matching on downshifts. It's pretty fantastic.

No brag. In agreement ; DCT PDK auto blip cars are great technology. One Id choose if building a competition car, needing every half second. But for pure enjoyment, it's another element of working @ to perfect the craft.

Ask ESS to show you what the servotronic programming is. Benvo from BPM has shown the graph of OEM versus his customization. BPM's is very linear.

@exclusivs I got tired of having heavy steering. One huge concern when I lost the m button was servitronic. I was forced to use normal setting. (Omp wheel with no m button).
I had the best drift session of my life. So much easier and smoother and to control. Never again sport steering

My E46 M3 has a tune and I've reduced the limiter from 8200 to 7500. It's less stress and more headroom if I miss a shift. The S54 usually peaks around 7200ish and is kinda flat up top. Not saying you should go lower than 8300 but 8600 is surely going to put more wear and heat in the motor. The question is whether you are OK with that. IMO, I've found that stock power is fine. Really could use shorter gears (especially DCTs), more rear suspension travel and cooling (brakes, oil, DCT). My theory is the E9X would be absolutely fantastic with a good clutch style LSD.
