I dont know the HP/TQ rating of BM3, but the JB4 can add up to 100 HP and 140 Torque to the wheels. That's nuts to me. I consider 523HP and 553 TQ already mindblowing. |

Thanks to all for the input and advice. I've sent a message to Mike about bm3 and also sent an inquiry to Carbahn. I had not looked much at Dinan since Steve Dinan now owns Carbahn, but I will do my homework on that also. There a couple of Indy shops in town that have been highly recommended. Maybe I can get some input from them, also.

From what I've been reading all these tunes require 93+ octane, yes? Should that be the case, then there's no benefit for those of us restricted to 91 octane to get a tune, yes?

From what I've looked at this morning, there are some for 91 octane gas also.

Supposedly the piggyback cannot be discovered by dealerships if you have any issues, but they can if you reflash........that's the rumors at least. I guess if you flashed the ECU back to stock it would be the same as removing the piggyback. |

Carbahn Tune Installed — HOLY SH*%
It would be a lot to explain.
Piggyback are hardware that plugs into a few sensors and alter/tricks the car's computer (ecu/dme) to get more hp. However the factory ecu parameters are not changed. Bm3 is a software that reprograms the ecu to increase hp. Flash tune reprogram ecu - timing, boost, fuel etc). There's tons of info on this forum and google on this subject. I would highly suggest you do some research and have a basic understanding of the 2 before diving in. |

Piggyback is a little bit different since it doesn't overwrite the dme and supposedly doesn't leave a trace. Most users that I've read that get caught with a piggyback were the ones who left it hooked up. Can they determine that you had a piggyback? If they want to. Modern cars are mini computers that log everything (more boost than stock, increase timing etc). But would they go to that length? Probably depends on what the repair is. Injectors, sensors, fuel pump? Probably be fixed no issues. Engine replacement? You better believe it's going to bmw regional where they'll pull logs and analyze the data. |

@PPMKING HerkHealer
Thanks for the explanations. I did read some of that today but I was confused because I think I had the Dinan (piggyback, apparently) mixed up with the Carbahn flash tune that I read about earlier. So of the ones I read about earlier, Carbahn and bm3 are flash tunes while Dinan and Racechip are "piggybacks". I have likes and dislikes for both, so far. The Carbahn product says that they are especially conservative and keep everything safely within the engines parameters. According the them, by actually resetting the computer and dictating the new parameters, it is safer for the engine than the piggyback systems that "trick" the existing program. On the other hand, I like the idea of being able to basically just unplug it if I want to for some reason, or if I'm going in for service. I'd just need to get more comfortable with the "safety" aspect for the engine. Also, it seems like the piggy back would be much easier since I'm in a smaller market and it sounds like I can install the piggyback option myself. Is that correct?

The Dinan and Racechip piggybacks are almost identical and offer modest gains of IIRC about 40hp to the wheels. The JB4 piggyback goes up to 100hp/140tq on a M550, and it also has a "Valet" mode to keep those crazy car parkers in check. I really like that on the JB4. Its up to you, but for me I would not flash my car since M550 motors cost roughly $30k and if anything were to ever happen, i dont want them to know about it. |

The flash tune sounds cool. Both Dinan and Carbahn explain with confidence how they will be sure it doesn't affect the long term reliability of the engine. But I don't know if I have the stones to install something like that on a daily driving car that I need to function. This is all interesting the learn about. Having this car has really become a hobby all of its own, which is right up my alley. Very cool. And this forum makes it all much easier to learn.

Good explanations here. Let me try to dumb it down. Think about the ECU as the cars brain that tells the other parts and engine what to do, such as fuel mix. The ECU is a computer programmed with BMW's settings for telling the engine and components how to run. An ECU flash tune over writes BMWs settings with settings that are more aggressive and increase performance. The history of how the car runs from that point are stored in the DME and ECU, so BMW knows they were altered.
A piggy back has its own "computer" and setting that alters the commands outputted by the ECU after it sends the instructions. It's plugged into various modules and changes the instructions for the modules. It's so downstream, nothing is logged.
