Stage 2 Protune @ Dyno Authority + More

[laueddy]

I just wanna post my Protune result @ Dyno Authority (Redmond, WA)

People there are very friendly, and the tuner Tim Hadfield has been awesome. He is not as familar with the Cobb Protune software, therefore alot of time was spent on the non-tuning part on Day 1. (eg. We have to workout some software bugs, and communication errors). However, he is very patient, and show no sign of rushing. I ended up spending my time there from around noon to 6:30pm.

The result isn't as good as we want, and there are still something he would like to work on, so I went there the 2nd time today. This time, everything works well. The tune is started as soon as we do a couple of WOT Dyno Pull to make sure everything is at least as good as last time.

This time Tim was able to spend 1 hr of good tuning time, and the result looks awesome on the Dyno Chart.

Since I know very little about tuning, and my concern isn't on HP alone. I don't want to blow an engine or killing my turbo in a few month or a year. So, I posted the dyno result and a ECUExplorer Log that was logged when the car is still on the Dyno after all the final tune. Please share your opinions.

Thanks

The following is part of my summary on the result:

This are Dyno Result for a 2006 STi Stage 2
PDX OTS Map
COBB OTS MAP
ProTune
ECUExplorer Log @ Final tune on Dyno

When I first went on the Dyno, I was on PDX OTS Map (With recent ECU Rest, the result was horrible.

The 1st run after the ECU is reset (PDX OTS Map)
Result
237WHP @ 6250
234WTQ @ 4500

After a couple full throttle pull, the PDX OTS best # are
247WHP @ 6250
258.8WTQ @ 4250

The Original OTS Cobb Stage 2 Map is almost as good as the PDX OTS (Check the Dyno Chart)
249.9WHP @ 6750
248.3WTQ @ 3750

Final Tune @ Dyno Authority
280.9WHP @ 5500

Wow, numbers look great.

That settles it, I'm going there for a protune

[Peter Hadfield]

Hmmmmm, could this be my long lost cousin Tim?

[Master2192]

wow those are some rich AFRs. Ignition timing looks similiar to the tune I did today but the timing on my tune is 17* at peak torque rather than 15* but we were probably using higher octane fuel (Cenex 94+). AFR Target for my tune was 11.5 as well, but again higher octane. Wonder how the two tunes stack up to each other

[Dunkin]

Thanks for the kind words Eddy! Glad you are happy with the results.

Ryan @ Dyno Authority.

Sweet results.
However, since you posted up the logs and graphs, you are obviously going to get a little critiquing of the tune.

From the log: the injectors appear to be over 100% and AFR's look real rich.

You probably have about 20hp in fueling. Plus, once the AFR's are fixed, the injector duty cycles will drop down to acceptable limits. The map is very safe and the power numbers are good.

In the end, a safe tune and a pleasant experience is all that really matters.

I know that the ProTune is new to those guys and it's a good way to start by having happy customers. Hope them the best!

[kirkeemonster]

what type of dyno?

[Dunkin]

It's an AWD Mustang Dyno with dual eddy current motors.

[C J]

if you dont mind me asking what kind of $$ did you spend for the tune and dyno time? PM me if you want.

[cmx168]

i would like to know how much it ended up costing too! please pm me when u get a chance also, do they do ecutek?

The dyno chart on the Cobb web for STI indicates stock WHP 238 @ 5300RPM & Torque 248 @ 4500RPM Stage 2 whp 277 @ 5400 And Torque @ 316 @ 3400

What would explain these differences for the SAME pro tune

1st, those numbers on their site are for off the shelf maps not a pro tune, 2nd the numbers are from a different dyno so you cant compare them directly, 3rd those are from a website that is used for marketing purposes....

So you are saying that since it comes off their site not to expect those numbers for an OTS map...Inflated for sales??

That, Or:
1. Every car is different
2. Your car probably isn't using the same fuel or in the same enviroment as the car that put the numbers for that tune.
3. Poor Gas
4. Other mechanical issues that keep your car from making that power

I have Cobb stage 2 on my Forester. I cannot verify the HP. I do now it is running rich. I am looking for a pro tune in the Seattle area. Before I spend the bucks. I wont to verify the tune will be an inprovment. With the Cobb, I have walked away from a stock STI. I run my car at SIR. It will run away from a stock WRX.

If you are running rich, there will be an improvement.

I have quite a few dyno charts that show improvements over COBB OTS maps; some as little as 10, some more than 30hp. So any custom tune (with a skilled tuner) will net you more power. Doesn't really matter the tuning method, UTEC, Open Source, ProTune, Hydra, etc.

Each car is different. That's why the cobb maps are rich. They can't hit the peak targets on one car and sell that map. It could run way too lean on someone else's car and blow up. They have to make a map that can help compensate for the idiots out there who do dumb stuff like crank up their MBC.

As a tuner yourself, I bet you've got basemaps that you start off from that run rich AFRs and low timing and then lean it out / advance the timing to each car's needs.

bingo.

I call them my "starter maps". Not sure why I don't call them basemaps...
I just like starter more I guess.

[Master2192]

hehe, to each his own. I think of tuning kind of like building a house (though...I've never built a house...). You need a base to put the foundation on, then build on top of that continually until you are done with the complete project.

yes.. I am crazy

You got it man, it was a n00b mistake on my part.

We are in the process of registering as a vendor right now!

That they are, but I am OK with that. Since we are new to the game, it's at least good to see that the Mods are keeping everyone on the up & up.

As soon as Nick emails me back with the instructions on becoiming a Vendor we will be legit.
