Having some computer trouble today.. I'll ahve to run this on another laptop tomorrow..

 

Jack,

Would you mind posting one of your recent datalogs now that the new firmware is out?

Thanks

 

I will once I get more seat time in the car.. still working on my blowthrough setup and getting it adjusted with the stock ECU..

 

Any updates on the power graph?

Thanks MalibuJack

 

Here's your graph.. NO CORRECTION but same parms otherwise.. I have to assume your running conditions were similar, or a little cooler than your prior run.. But its still a decent gain regardless..

One suggestion, the UTEC didn't register knock, however the factory ECU "recommended" pulling a large amount of timing, leads me to believe that the car is running lean from 5500-7000 so add back about 2% fuel in that range.

What I do see is you have a nice stable boost curve, but a small DIP indicates a slight shift in timing that you can tweak.. but add lots of fuel if you want to attempt that..

 

FWIW These kind of numbers are what you'd likely see on a mustang dyno.. (I've been playing with their stuff recently)

 

Thanks MalibuJack for the Power Graph Display?

What does that equates to to a Dynojet Dyno?

I will go ahead and tweak my fuel curves adding about 2 percent from 5500 - 7000rpm

Is that a descent gain for my setup?

Also does the run affect the log if you pull in 3rd gear in a moderate uphill.

The freeway entrance that I did the run has a slight or moderate uphill, does that affect the HP results?

How about going slightly downhill? would that increase the HP overall?

Thanks

 

For best results the road you use to do a data run on should be as flat as possible. Also if you get really pedantic there should be no headwind / tailwind too.

The road needs to be as flat as possible because the power plots are being generated by calculating acceleration of the vehicle. If you are going uphill or facing into headwind etc you will be going slower ( marginally maybe depending on slope of hill / strength of head wind ). Likewise if you are going downhill, you will accelerate faster.

An uphill plot will likely show LESS power, and a downhill plot MORE power.

Oher factors to influence the results are :
temperature and humidity like an on a normal dyno run
weight of your vehicle - for example if you make a run on a near empty tank etc

 

Additionally wheel/tire size (if your not running stock), and frontal area differences if you have aftermarket bodywork (most available kits are done for show, but are terrible for aerodynamics) and drivetrain losses (I still haven't zoned in on the correct loss %'s per gear therefore the numbers probably are about 10% higher)

The gains you have made for your mods are definitely good for you mods. Some cars run stronger than others too and do have an impact on how they respond to modification (my car is a good example of that, Which was observed by some people who have tried maps that I have been using on my car)

 

and a slight uphill run would read slightly lower... Its best to always do your runs on the same stretch of road, whether is slight incline or decline, as long as you do the same runs, and keep track of the air temp and humidity, you will have data that is consistent, and correction information, that allows you to offer run to run consistency for steady state testing (multiple runs with the same mods) and be able to detect gains and losses..

the ultimate numbers aren't important, only the gains from YOUR car, before and after.
