On a mustang dyno you enter all that information.
Automatically changes everything for you, hence why I said
the mustang dyno is a true tuning dyno vs a dynojet, where
all it does it gives you high hopes and numbers.
On a dynojet you have six settings to choose from:
Uncorrected
SAE
DIN
EEC
STD
JIS
Hell I even called up my old job and the shop where I was
going to use a mustang dyno verified they don't have those
settings to choose from, you enter all the information and
the dyno automatically corrects it for you. Oh and they both
have updated software too.
I don't have access to mustang dyno software, sorry so no
proof for that end.

02 C32 AMG sold!
away in that last post. Sorry about that.
But what I was trying to point out, that in a Mustang Dyno,
there isn't any features or options to change the results
like you could on a dynojet, which made me wonder how was he
able to come up with two figures on a mustang dyno session.

Oh Erick I agree with you there, I don't know why I got carried
away in that last post. Sorry about that.

i can't give any input on the mustang dyno other than what i have read on the internet because i have no first hand experience with them...

With all due respect to those who perform dyno testing, please be mindful that the entire process is merely another tool in the repertoire which one can exploit to hopefully improve performance. Nothing more.
IMHO, there is far too much emphasis placed on the absolute numbers generated and recorded, rather than interpreting the data and making hardware/software changes accordingly. There are dozens of variables that affect dynamometer readings. The exact same car on a different dyno will frequently generate disparate figures…even under seemingly similar atmospheric conditions. The figures produced are, more often than not, accurate in a relative sense. That being, for instance, during A-B-A testing of one component or tuning variable, when a repeatable gain is indeed achieved, than by all means be pleased with the change implemented and know that it’s helping the cause.
When testing a new motor tweak, I prefer the dragstrip. With readily available OBDII data logging equipment, myriad pertinent information can be downloaded and recorded for future study/interpretation. Trap speed is an honest, repeatable indicator of torque and horsepower. ETs are more closely related to available traction and 60’ times. Besides, it’s more fun than flogging the poor thing on a treadmill.
Doug Roe, a widely respected engineer, shared “…when you are testing and the results disagree with your hypothesis, invent a new theory and believe it!”
This is not necessarily directed towards you, TrojanStealth. Just trying to help.
Kindly forgive the threadjack.
