Vagcom og Butt-Dyno

[Hurricane]

Noen som har fått Butt-dyno til å fungere med Golf 3? Får opp avlesning på Block 005 under Engine, men istede for "speed" så får jeg bare opp "RPM" Noen tips?

Gjelder 96modellen.

 

For dere som ikke vet hva Butt-Dyno er http://forums.audiworld.com/vag/msgs/457.phtml

gruppe 005 er ikke lik på alle vag, kommer an på bil, motor valg osv. Ikke sikkert dette fungerer på en så gammel bil som 96.

There is a lot of new products that plug into your OBDII (On Board Diagnostics) port and claim to measure horsepower, torque, 1/4 mile etc. We have studied the OBDII protocol and the problem is that OBDII system was designed as a diagnostic tool to be used in a mechanics shop. So things such as timing accuracy and speed of the sensor readings were not critical. But for performance measurements you need exactly those things. So when it comes to measuring performance through OBDII that is a problem. It can be done easily but it's not accurate.

 

For performance measurements you need acceleration. OBDII devices calculate the acceleration from speed and time. In theory there is nothing wrong with that method but the problem is resolution (how often is the speed updated?) With OBDII it's only a few times per second! So acceleration readings are "choppy" and not accurate.

 

Koster selvsagt noen kroner, men GTechPro har mye bedre nøyaktighet. Leveres med software og kan konverteres inn i Excel :)
