Like doug said, they should make a tune file to lock the car in 4th, from there just floor it. Im gonna get my car dyno'd soon and im gonna have him send me a file.

 

...im trying to post chart. sorry

 

Hey Po,

I did a dyno run yesterday on both a n/a auto and a S/C auto that looked great. Did he put it in 4th and press the OD off button? I can't figure why the graphs look like that. When I make a pull I just lock it using the files that I sent you and put it in D and press the OD off button and then once it hits about 2500 rpm's above around 25 mph I floor it.

Sorry you're having such problems, just let me know if there's anything I can do to help.

thanks, Doug

 

Yes, OD and TCS were off. I think it was because he didn't floor it. It sounded like he took his time to get to WOT (about 4-5 secs) which may have caused those spikes.

I'm not as worried about how the dyno sheet looks as much as whether it's my car doing the spikes and not the dyno.
