Detonation: Detonation is the spontaneous combustion of the end-gas (remaining fuel/air mixture) in the chamber. It always occurs after normal combustion is initiated by the spark plug. The initial combustion at the spark plug is followed by a normal combustion burn. For some reason, likely heat and pressure, the end gas in the chamber spontaneously combusts. The key point here is that detonation occurs after you have initiated the normal combustion with the spark plug. Pre-ignition: Pre-ignition is defined as the ignition of the mixture prior to the spark plug firing. Anytime something causes the mixture in the chamber to ignite prior to the spark plug event it is classified as pre-ignition. The two are completely different and abnormal phenomenon. |

Actually if you remove any timeslip run at Sacramento Raceway (shiv, startupjunkie, hotrod) they are all similar. Or if you want to include them in the conversation, subtract 2.5 - 3mph from their trap speeds.
And I'll even show u a timeslip of someone who ran FASTER on Procede over JB3... Look up yandyr in the 135i section of dragtimes. He went from 12.0's to 11.7's, trapping 2 mph higher when he went from JB3 to Procede.

By that logic the JB3 is superior to the JB4 as well.

What we are starting to find out through other threads is having a flash is conveinant, fast, easy and very user friendly. Now like the post said, the Flash is a generic map that is utilized with many vehicles = Safe, Generic and may not perform to the best of its ability.
The Flash's and Flash Tuner's, unless dyno tuned will never perform to the optimal capability of the car, which is always safe but to us car guys is not the same. Following up with other Threads, these flashs have the capability of returning it back to stock parameters, but BMW is smart and have in essence a "black box" that records valuable information. This information CAN NOT be erased or even tampered with. So raising BOOST will be recorded in the "black box", if they wanted to pull that information for whatever reason. GIAC just ran into a problem trying to reload the factory files back into the DME but with the new BMW update means a new part number was issued for that DME... |

no worries - naturally aspirated cars are not able to make power easily - they require heavy modifications to make even slightly substantial numbers - the n54 being twin turbo allows easy gains because the turbos move a fair deal of air at higher boost levels equating to great #s on the dyno

GIAC will crack the new file as soon as they get there hands on a DME that has it, no big deal. I know of at least one of the GIAC guys owns a 335, I was told i'm actually running the same Stg 1 map/software as he is.

If you erase all the codes using a BT Scan Tool, will it guarantee erased codes? I feel like seem to have the least popular software (AA Xede) and have trouble with reference to erasing codes- I love that is has a on/off switch, but don't know if it get recorded.

Think of the piggyback as the man in middle. It reads from sensors, does its thing and then sends the resulting signal (with its alteration) to the ecu.
