I'm desperately ooking for some good datalogs while strapped on the dyno to compare with the UNcorrected dyno results. Lemme know and I can tell you the info I will need about your car and possible about the dyno's parameters. If you have old datalogs while getting dyno tuned and still have the dyno results (UNcorrected please), I can try that as well. The only catch, the datalog should be from the exact some pull that the dyno printout was from for the best accuracy.

Thanks fella's!

 

mayb in 2 weeks ill b hopping on ivys dyno to get my e85 on. if you sill need them by then ill b sure to submit em to you! keep up the gud work btw.

 

Yup

Dyno Dynamics in the UK in 2-3 weeks.

Let me know what info you're after...

 

Hopefully will have my car on the dyno in 1 or 2 weeks.

 

Thanks guys! Shoot me a PM just before you guys head to the dyno and I can tell you any dyno info I may need.

 

Just curious, how do you plan on comparing the dyno plot to the VDR results and then applying it to how it works on a street pull?

You are accelerating the dyno load on one pull and the car on the other?

 

Whenever I can get the true data straight from the dyno software in an exported file (most good dyno shops will export this for you if you ask) I load them in the VDR graph and scale the datalog graphing to be as close as possible to get me in the ballpark. Due to scaling variances between VDR and the dyno, its never 'perfectly' aligned but I have got it to be DAMN close these days.

After that, I just try to compare street pull logs from the same car and make sure they reflect nearly same figures when loaded into VDR vs. the real dyno. The more dyno's I get data from, the better I can create an average scaling for a particular dyno 'type'.

Dynojets are the most repeatable from one shop to the next but Mustang dyno's have a great deal more HUMAN entered data so there can be greater variances from one shop to the next.

Here is one sample of datalog data vs. exported dyno plots.
