I think for the BMW 2.0 engine used for their branded 1.6 - 1.8 - 2.0 (2 versions) and the 2.5, it is all soft ware related except for the 2.5 where there is a different turbo an some extra cooling I will see if I can find something in writing on any of the European boards. I agree that is seems odd specially when we know modern engines are more or less ready when you buy them (maybe except 1000km or so). When you say the F15 US versions is detuned, what do you mean by this? I recall the E70 generation 35D (which had 2 turbos, whereof the F15 35D only got one - identical to rest of the world 30D), the US version had around 20HP less than rest of the world due to emissions etc. But I was not aware of the newer US BMW still are detuned Have a great day JensM |

Opplock1 42pilot JensM And others who have experience with the RC for diesel
- Have any of you purchased or are experienced with Racechip One and/or Racechip Pro 2? - If one buys the Pro2, for instance, and set it to a high (or highest) setting, do you think it will reach the E2 level on the "Ultimate" version? My objective is to avoid any all possible errors. If I can replicate the minimum improvements of the Ultimate with a weaker chip, that would be satisfactory for me. Thank you.

Is the F/6 or 7 setting close to or the highest for both torque/hp?

@MattBianco, are you in a market for the RaceChip? Lmk, I have the ultimate in stock.

It's called capitalism. Besides I don't think he was against it, he just didn't have experience with it, whereas he had tons of experience with the JB4 tunes. Racechip is a great product.

I didn't like RaceChip due to the lack of support and correct information on the community. I am trying to sell RaceChip because I wanted to help you guys more by learning on the products. I am also going to carry Dinan products also. And just because BMS closed my account, that doesn't mean that I can't sell the products anymore.

Race chip One vs. Racechip Pro2, Vs. Racechip Ultimate
This is not worthy of a separate thread, but here is a recap of my understanding as well an explanation for the difference between the three chips, and how it works with the N57 diesel engine. The observations are based on an email I received from Racechip, my self-study, and feedback from other users here:
• Racechip: "Setting ‘E/2’ is in every RaceChip more or less the same performance level and way not the maximum that can be reached". Deduction: settings in all three chips respond proportionally the same way. Racechip One, must therefore not have the all the same settings. That also explains they minimal power difference between Pro2 and Ultimate which have the same number of settings. • The only key difference between the three chips is the processor. Race chip: "Actually the difference between the three RaceChip is mainly the processor: The processor can optimize the values as faster is the throttle response and the performance evolvement, the engine runs smooth...". Deduction: the feel of the more pricy chip will be better as it makes for smoother throttle adjustments and responds to engine readings quicker. • They have "done a lot of tests with especially this N57 block we do have many recommendations concerning different settings.....", with some "...stronger than E/2 but still not causing any error messages." Deduction, we can take it up a few notches, but maximum is probably not advised. Don't buy it for the advertised maximum power increase, but for somewhere between E/2 and max is the general consensus. • Pretty much like opasha mentioned earlier, the faster processor produces a smoother power gain. Question however, what is the processing speed for BMW's engine computers? If the car's processors are at or around the "Pro2" level, we could be throwing money away. paicapo could chime in to say if there is any difference in smoothness of throttle response and rate of acceleration change -smoothness. • Although everyone says E2 setting is fine, including Racechip, we do have a user that got the Check Engine Light (CEL) at E2: http://f15.bimmerpost.com/forums/sho...&postcount=100 • We also know that this is a chip, not a tune based on other emails from the manufacturer 42pilot: http://f15.bimmerpost.com/forums/sho...&postcount=182. In a thread I cannot find now, I recall reading that the believed advantage of Racechip over Burger was that it was a real tune, and not just more fuel. • We have skalberti who cautions use based on personal experience, as BMW is able to identify if a car has been tuned/chipped: http://f15.bimmerpost.com/forums/sho...&postcount=228. Meanwhile I asked about the chips at Service yesterday and one of the advisors said something to the effect of "we all have chips in our cars here", and that he preferred Burger. • Racechip does not always know the answers despite the claimed tests -there may be trial and error speculation vs. real tests. User catapaul switched to setting 0/3 (O/3?) as Racechip recommended that for his 40d; at 3500 the engine would choke. He has only a single post in this forum from NOV'14, and no one has replied to him. Unlikely he will chime in, but hopefully he gets a notice about this post and lets us know what happened. http://f15.bimmerpost.com/forums/sho...&postcount=230 42pilot also reports conflicting and later corrected comments from Racechip (linked earlier). This is not an easy sell for me as my wife is the primary driver, and I use the car on the weekends to chauffeur the queen and the children around. It has to be fail proof. Meanwhile, BMW has its own chip for the 30d, which one could argue should be a near perfect match for the 35d. Power gain is not as much, and neither the personal tension and attentiveness that may be needed: http://f15.bimmerpost.com/forums/sho....php?t=1045505 It seems one does not need to buy the whole kit (including brakes) as the chip has a standalone price and part number. I admit to having no experience on this subject, and limited second and third hand knowledge from my self-education attempt. And, for now, I remain on the side lines. Perhaps if I leased my views would be different.

No doubt the US version is de-tuned for emissions but that does not mean you can flip a switch and safely turn up the power with a chip. And certainly not with an ECU that has millions of lines of code and the dozens of sensors. This is exactly like stating, put a bigger exhaust on the car and it will run better because an engine is really a big air pump. Change one thing upstream or downstream from your alteration and it affects everything. Trivia question: on a 3.6 boxer fuel injected (not DI) turbo motor, which size header diameter is most appropriate - 1 1/4 in, 1 1/2 in, or 1 3/4 inch? You are right in that the turbo will probably not break, but the constant pounding of igniting fuel on top of the piston over time will damage bearing, rings and the piston itself. For example, just changing the amount of fuel vs the temp of the incoming air will make a profound difference in performance and engine longevity. Most, and I mean most, bolt-in tuners simply add fuel and maybe timing (spark or fuel). That's not a smart strategy on today's engines and you can expect long term problems if dialed to the max. Sometimes, relying on the CEL to catch the problem is too late. I once tuned a gas turbo motor with knock sensors to avoid detonation at high rpm. According to the log, within ~1.8 seconds, I burned holes in 3 of 6 cylinders and trashed 4 pistons - that fast. Then the CEL lit up. This is why I checked on RC for so many weeks - spoke to them, researched them, found out if they had warranties anywhere, asked how they tuned (NOT IDEAL !!) and so on. I will not turn my tune all the way up - I own the car and plan to keep it. If you see you are using oil a bit faster than normal in the coming months, you now have a probable idea why.
