How to turn off ESP completely for Dyno
 

Hi,

I have tried to search the forum and found a few threads discussing about the VDS button but no real conclusion. I have tried running the car on a Mustang Dyno with the VDS button off but I think the ESP is still kicking in whenever I put my foot down. The car would rev very quickly for a split sec from idle to about 1800RPM and then it would suddenly pull back and rev up slowly until it hits 3000rpm. It will then start to come alive again after 3000rpm. Can anyone help with this?

Thanks in advance!

A/F change........UpRev.





And what the heck is "ESP"?

Electronic Stability Program...

Are you saying this is due to my air fuel ratio at sudden full throttle? Then why doesn't this happen on the road?
