You are correct! However, it will turn into that. It always does. Then somewhere down the line TTP's MD gets thrown in the loop...

I have personally never used DLL, but I hear it is within 2-3% of a DJ

Yep, your probably right.

You should log a couple runs and run them though DLL and VDR and see how close they are to your actually DJ numbers.

 

^ I would but I don't have the software. I have not grown enough ***** to start tuning my own car or mess with any software of that type... I have ER to take care of me and they always have. Hell when I PCS to another duty station I will prob ship my car to them or take a nice drive to just go to their shop. Great guys all around

My fiance is buying me one of those "small" HP Computers with evoscan at some point so I can start to learn but it will take me awhile to fully learn how to tune the car. I'm sure it wouldn't be hard to blow it up though...

Mikey

 

Yep, your in great hands with ER.

And yeah, you can just grab a laptop/netbook, cable and evoscan, then doing your own logging and not worry about tuning. Just leave that up to ER.

 

^ That's what I plan on doing. I know my way around tuning coming from the Honda Crome side of things but still not that familiar with evoscan.

Ok, so i started this thread to find out what the differences in HP readings are between the three methods. Here is a real life situation that i have recently experienced. In no way do i mean any disrespect to Mellon because he is, in my opinion, the best tuner.

I had my car tuned and in DLL it read 540awhp. I take my car to a mustang awd dyno today and it reads 435 awhp. that is over a 100+ hp difference? I gave all the correct specs for my car to be entered in DLL.

couple of questions.....
1. Which one is true?
2. Why are these so far apart? i could understand +- 50hp but over 100???

if DLL is true, then why did i get pulled by 1-1/2 cars by my bros c6 Z06 that makes 463whp on a dynojet dyno? At the DLL spec i should have whooped his A**!!!

The mustang dyno was at Secret Service Auto in houston, tx. and according to them it was calibrated.

lets get some real answers to these REAL LIFE situations.

****In no way do i have bad intentions or feeling towards Mellon. I merely used him to show that an experienced DLL user gave me my DLL number.

 

Is secret service different from Cobb? I thought Cobb was in TX, but someone said Utah yesterday.

 

yes it is different than cobb. Lets try to stay on the topic please.

 

Why don't you just take it to the same Dynojet your brother did? You cant use a race to calculate or compare numbers, there's aero, weight and driver equations that take place too.

 

I answered your question in post #13.

DLL dyno reads like a Dynojet dyno.

A Mustang dyno reads a good amount lower then a Dynojet dyno, hence a Mustang dyno reads a good amount lower then a DLL dyno.

For reference, 100% Stock evo 8/9 =

Dynojet avg. 250-270
Mustang avg. 205-230
DLL avg 250-270

Also, I find VDR (Virtual Dyno simulator) to be better then DLL.

Maybe run some logs though VDR. VDR also has a Mustang dyno setting.

 

I understand that the mustang dyno will read lower.... but 100hp lower???? doesnt make any sense to me. dynojet usually reads 12-15% higher than a mustang so if you do the numbers that is still not close to the DLL # given 540awhp. Does that not raise any questions about the accuracy of DLL??

 

A 100hp does seem a lil excessive. But I do have these two "facts",

-400hp on a mustang is usually about 450 on a DJ, which is 50hp difference.

-Now according to this thread, https://www.evolutionm.net/forums/dr...me-thread.html

AWD motorsports car did 921 on a DJ and 803 on a Mustang. That is a 118hp difference.

Also, DLL is like any dyno, there is variables. Operator, condition and most importantly, the road.

Given all the above info, I'd say it has to do with a lil bit of DLL Road dyno error and a lil bit of just a mustang reading lower then a DJ, or DLL in this case.

EDIT - I'd like to add this, a lot of the time on DLL dynos there is upswing at the end of the HP plot, which gives higher then correct numbers. It has to do with how the dyno is calulated, which is by averages and sometimes, the averages get screwy near the end of the run/log.

This is the EXACT reason VDR has a "max RPM trim", so you can correct those incorrect upswings at the end of the HP plot.

 

For myself, DLL and VDR always read higher than what I put down on a Dynojet. Right now all my logs fed through VDR says between 470-485whp @ 28psi vs my 450whp @ 29psi on a Dynojet. If I drop the scaling it even goes higher..

 

Nevermind...

 

I hear you boosted tuning. there are alot of variables that come into play. thanks for clarifying some things and making good points with facts. I honestly don't feel the DLL is correct. If it was then i would have beaten by brothers C6 Z06 that made 463whp. Does anybody disagree with that? I mean 540awhp vs. 463whp?
