Ahhhh, I forgot to mention the trucks. They are TERRIBLE! And yeah, yours would definitely stand out even more being red! I guess living in redneck state has its drawbacks as well! :P

As I understand things, ESS has provision for saving/restoring the factory ECU program, so there should be no issue with scheduled (or even unscheduled) dealer service of your car. So why would you forgo such a major improvement in performance for such a long period of time? I'm assuming cost alone is not an issue as it is less than $20/month over the warranty period? Can you elucidate your thinking for me here? Thanks in advance. P.S. I still hurt for you and your spanking. Good thing no one but you and the Vette driver knows who won! Oh, wait, you went and told the whole world about your humiliation. I may just have some more questions for you... |

I'm sorry, I don't mean to be obtuse here, but I STILL don't understand. Are you saying that you have an expectation of legal action against your dealer/BMW, either directly or through Lemon Law provisions? And that this possibility forestalls use of any ECU tuning programs? I thought ESS tunes were wholly reversible in the sense that the original factory ECU program can be reinstalled with a minimum of time and effort. Surely the dealer would be unaware of any tuning program once it had been removed. Are you concerned that, in the event of legal proceedings, you may be deposed and questioned on this matter? Whatever the case, I sympathize with your situation; it must be terrible to have one's freedom to enjoy a beautiful car so constrained by the possible actions of others. Good luck.

And GC8 actually set up to run road corse on tomei trany and final drive not drag. My 997 runs mid11 on drag strip on hoosier and doesn't really set up for drag. Those 2cars can be driven from my house to safeway buying food and grocery easy. also can clock sub2 around thunderhill raceway. I know that those v8 at drag strip are seriously fast but those v8 guys who hang out do street racing and stuff around where I live are gay and got dust all day long by import. not only that.... It's seem hard to find low11 or 10 sec car on H pattern V8 driver. They all go transbrake and automatic shit. Haven't got smoke by v8 on street yet so I don't know why would I have hard time

What I've read is that if your car is modded and you have a drivetrain failure then you pay to fix it. Also, other posters have shared that there are ways to detect a tune such as paint marks on Ecu pins or recording the turbine speed of the turbo to check if it is being used at higher than stock boost levels.
I personally wouldn't modify unless I was ready to fully pay for the worst case (engine or gearbox failure). One 335 guy had oil starvation from high g turns at track and another has his meth kit fail and hydrolock the motor. There is always some random thing that can come up! ashborn, the c7 isn't out yet (the knowledge of the upgraded new model is part of why I didn't go vette this time) Also, I think you misunderstood me. "I can't wait" because its exciting to have something better to step up to, not that I am unhappy with my current car. |

Additionally, I would caution against use of the term "modded" when referring to flashed ECU tuning maps as it generally refers to mechanical modification or replacement of intake, exhaust, suspension and/or major vehicle components. |

"Hoss". I love it! I haven't heard that since I lived in Virginia.

I know some other southern expressions, but I'd get kicked off this forum!

you are saying +60 to 100hp via aftermarket ecu reflash isn't modding because nothing mechanical has been changed. Lol. Hope you don't need any power train work done under warranty. Higher torque and more heat contributes to things breaking. It is very naive to thing you are getting "free hp" without drawbacks. Btw I personally think that "not overboosted" is deceptive IMHO. Peak boost might be at oem max but if boost target at given rpm is higher than stock that is "over boost" |

Good info. Thanks.

I do agree that while Stage 1/Stage 2 tunes claim to "do no harm," the reality of engineering compromises is impossible to avoid. That said, there is no evidence I have seen that demonstrates an ESS Stage 1 tune applied to the N54 engine has any deleterious effects. In fact, I have seen many comments (certainly not evidence, but ...) that "boost" levels in the stock 35is are somewhat harsher and more abrupt than those provided in the Stage 1 tune.

I hear what you are saying, and I've seen the threads that suggest the N54 and N54T share the same parts and that the 35is and 35i are ECU programming differences
Despite all that "info" we're all still speculating based on realoem.com part numbers. As far as I know there is no insider who has come out and said "yes the N54 and N54T are truly mechanically the same thing" so to chip the car or not goes down to your risk tolerance and your need for the warranty to pay for things that break Good example is the 19" "style 296" wheel where forum members have posted pictures of physically different wheel that is thicker near the inside lip but the realoem part number has not changed. EDIT: +100hp really does sound good though eh.... |

What I wonder is why the LCI didn't include the switch to the N55 (with Valvetronic) for the 35 and 35is. For the E85's LCI, engines were upgraded to the newer versions (N52 in my 3.0si vs M54 in my pre-facelift 3.0i). EDIT: Answered my own question. BMW felt the N54 "suited" this car best. |
