Me vs Turbo m3

[ChAmP_CoUpE]

i really wouldnt know since i wasnt the one who tuned it!!!.... shit i wish i could tune my car... hell its hard enuf finding people who like tunning aem ems! until than i gotta pay people to tune it for me....

[Hektik]

ill tune it for u greg ..... just let me hold the car for a weekend

lol haha fuk that lol hahha

[RJ's325ITS]

lol haha fuk that lol hahha

If you change that AEM for a bmw DME I'll tune it.

[Hektik]

lol haha fuk that lol hahha

lol it was worth a try

[BigPoppaHurtm]

thanx for holdin it doiwn for the s2k's mang

[Fast Shadow]

what kit are you running, pm me please if you don't want details in public. i still have my s2k and have thought about doing something with it.

[ChAmP_CoUpE]

lol haha hektik is crazy lol.... lol na ill stick to AEM lol i dont think it will work too good lol ... np gotta rep for the rwd honda!! lol

[ChAmP_CoUpE]

no prob ill gladly post it .... its an inline pro kit with a 3mm head gasket...

[o_bomb]

God damn can u break 400whp with that kit?

[ChAmP_CoUpE]

i can break 530 with this kit buts its pushing it...

Uhh.. technology is changed then. Plenty of cars have knock sensors that work at part throttle or at WOT. They're just microphones that are tuned to listen for sounds at a certain frequency. How they react to those noises is tunable on some cars.

wow... I have spoke with most of the euro turners out there within the U.S, dutchland & sweden soil, and all of them agree with me. They do not tune the WOT maps for the simple reason that the engine is so loud that even the factory tune do not take the knock sensors as a valid reading to adjust fuel or timing. But once again we have 3 levels to adjust: Idle, Part Throttle & WOT. In which each of theses have ignition timing and fuel timing, but the ignition timing is fuck up b/c we have to tune it for the Vanos which it will mechanicaly retard or advance the cam timing at Idol. PT & WOT, just like Vtech.

Do you have more info on this type of knock sensors, I will love to do some R&D and maybe make them work for BMW's.

I can log knock voltage no matter what other variables are, including throttle position. From what I understand, most other cars can do this as well.

Well off course Charles the sensor will work at all times therefore you will get a voltage at all times. If we wanted use the voltage as data we could, but how accurate are the readings "voltage" you will get of any engine at 6000rpm..... I think that is why BMW engeniers do not take those readings as a legit tool to help the DME adjust fuel or ignition timing.....

I believe most knock sensors are essentially piezo microphones. They're designed to produce voltage in response to certain frequencies. The ECU has a table that determines what the response is to the amount of voltage at a given RPM. By doing this the engineers that set up the car's engine management can configure less or more timing to be pulled depending on how much voltage the mics produce at what RPM. They know where false knock is more likely to be detected. I know this is how it works on several Japanese and American cars, no idea about German cars. I assume most German cars use Bosch Motronic engine management.
