The first reply is to control detonation because of crappy fuel - low octane or just crappy corner-bought fuel. The way to mitigate the problem is to detune. On the other hand, BMW does not over-engineer their engines too much (think cost/profit). Don't think you now have an M motor. Lot's of internals are different, including tolerances, material and parts. So put quality fuel in your car when running the tune.

Same here but I have been testing BP, 76, ExxonMobil, Shell, Valero and I'm going to confess Shell and Valero I notice it being smoother and more ump.
BP/76/Costco are cheaper is price or can be easily found 10 cents less but it burns faster and don't see the same smoothness. ExxonMobil only tested 1 tank but it burned quick so didnt bother testing. I am going to stick wtih Shell, Valero, Costco in that order for a few reasons. Shell: Fuel Rewards Network, I have just earned 40 cents off per gallon and now another 55 cents off per gallon Valero: 2nd choice, noticed good mpg too Costco: #1 Retailer and has cheap priced gas ( i will do some testing on MPG soon)

Hey all, I'm guessing the answer to this question would be the same for the X5 or the X3 (where I'm from)
What's the difference between RaceChip Pro2 and Ultimate? I know it says the Ultimate samples faster, but in real life, does it make any difference? Has anyone driven both to see if it drives any different? The power specs are the same on both. |

But based on the spec, the RC Ultimate is faster processor and have USB port for software update. Also, based on the price, $80 difference, it is a no brainer to get the Ultimate, especially after some discount.

Haven't seen too many people with the JB tune on these cars? PS How do the RaceChip maps work? I saw in the video it says he's running a D map or something? Is there documentation on it? Typically on other tunes, you're supposed to log before you go to the higher maps, and when I asked someone here about if you can log with the RaceChip (like you can with Cobb), they said no. So how do you know if you can move to higher maps and not have timing drops, etc? |

The hardest part is trying to disconnect the plugs. I am still trying to figure it out. Anyone got any ideas?

Kzang , Use a flat screwdriver or a pick and lift from the front. Pointed by arrow.

Drove it around town for a little bit and I can't really feel anything yet. I do feel a little oomph and the radiator fan seems to come on more often when I accelerate hard. The tune is at default setting. I believe I need to drive it around more for the car to adapt to the tune? I'll report back after I have driven it more.
Edit: After taking the car on the NJ turnpike for about 20 minutes or so I can feel the X5 come alive now. I'm liking the Racechip and it is every bit what others have said here.. it made me say "Wow!" Looking forward to finishing up my tank and taking the tune setting S2-B to S2-C

@Kzang , that's the difference between RaceChip and BMS. Because it is more smoother, you won't feel it much, but it is there.
It does take a little bit time for the car to adapt.

Hey all and pdawg,
Just curious, for those who are bumping up their settings to more aggressive maps, what is your process for making sure the engine is happy with it? On the E90 forums, where people log, they're logging the timing Corrections on all 6 Cylinders And looking forward drops there, as well as some of the other parameters. I know with Cobb, it was super easy to do and export the logs. With the JB tunes, I can't recall if you can do it via the tune, or using the Bavarian Technic cable, but again, people do logging before bumping up maps. Are you logging? And if so, with what? What are you looking for exactly? |
