haha thanks for proving my point http://www.flyinmiata.com/index.php?...07-77000++FULL

you want the "other ecu" version

 

well i have had another go at using this software.

however my hp/tq figures are higher than i expect - 379/364 so about 50-60 higher...

i have got the weight of the car right, and did the 3rd gear pull on flat ground.

any ideas?

 

how much are you guys adding into the weight of the car when your tank is full?

 

Interesting thread...apparently I'm 425hp

...but that's using an IX log with the default Evo VIII 5 speed settings in DLL

Gonna try plugging in the IX 5 speed gear ratios and see what happens.

Like poster above, am wondering what the best settings are for the car contents weight, etc. etc.

Seems that lower smoothing factors are also MUCH more accurate - 2 or 3 curve smoothing max.

 

Local atmospheric variables need to be correct, also.

All measurements, rim and tire sizes, coefficients of drag, etc., need to be spot on. If you don't know them, search through Google.

If you have upgraded aero, you need to measure and do the math.

 

1 gallon of gasoline equals 5.8 to 6.5 lbs. Weight will vary with temperature.

 

Hey, thanks for all teh excelelnt info in this thread. I've stuck all the right gearing info in, rim size, tire diameter etc. etc. and it mkes a biiiig difference...seems alot more realistic.

Only question is, if you're using as-accurate-as-possible parameters in DLL, what numbers are you looking at? Engine or wheel hp?

Also curious how DLL compares to different dynos etc. - whether anyone has any experience.

I know DLL is more of a tuning aid than a bragging numbers generator, just trying to understand it a little more.

Thanks!

 

its in wheel horsepower, not engine.

even with all the parameters spot on - i find DLL to be about 10-20whp over a Dynojet, but the curve is usually perfect, and thats all i care about for tuning.

 

right, I don't get too hung up on the numbers themselves...what's important to me is the gain over previous mods/boost/octane and the shape. It's proven quite useful for finding flaws in a tune that left a dip in the power curve and things like that.

 

Thanks, much as I guessed - ballpark whp numbers and all about the shape of the curve.

Spose I can use it to dial my boost in at least - with DLL all dialled in, I'm seeing some significant variation in the curves between pulls.

Good thread though

 

What's the cd (coefficient of drag) value you guys use? Some catalog suggest 0.3 - 0.5, so I pick 0.4 instead with ft2 of 2
