pretty sure I never saw the words stupid. As far as timing advance. How was this dyno getting that information. Was this an ob2 log? Maybe there was an issue with that and not necessarily the car.

Sorry dude, I meant DavesMeanE's. (I didn't even know your name was Dave)

Celicasaur

That's actually a very good point.....

...but that's the next thing I'd have said also.

Hmmm....

I think the best bet is for the op to take the car to a dynojet for more apples to apples compare numbers. Leave the tune as is,dyno the car in 4th gear IN DYNO mode lol and go from there.

I just loaded up my dyno files and here is my p31 on stock tune with afe pro drys and row boxes compared to final tune file.The rest of the car is stock other than tune,filters and row boxes.The before and after is tune only changes.

As you can see my air fuel never goes in the 13s and makes great power with stock exhaust!

DavesMeanE's

I don't even see anything on the graph that indicated timing advance.. If we are looking at the columns, are y'all looking at the center row? "TC_13 deg F" If so, I feel like that is an indication of temperature, not advance. Like skratch77 said, it looks like whatever pickup is used for populating that field was not hooked up.

I'm not trying to make anyone feel stupid, just trying to correct misconceptions No ill will here fellas.

FWIW - I don't log timing unless there is a problem, or we are headed to the ragged edge and trying to get every little bit we can. It's not a standard practice on basic bolt-on tuning.

My first instinct is to check the intake manifold, which you all should probably do if they haven't been replaced... It's as easy and getting the engine nice and hot, lifting the front of the airboxes, and spraying brake parts cleaner down each side of the BASE of the intake manifold. If the engine stumbles at all, even the slightest little bit, spray again to verify. If it stumbles for sure - get them replaced or do it yourself.

Thanks

Any update to this? Did op get another dyno done?

Here's a little snippet of trying to get in touch with Westech. "oh were booked due to shooting that motor trend show on YouTube. Come next week! A week later...oh The chassis dyno technician is out! Come back in two weeks"...giving me the ol' reach around.

Since my last dyno I got official Row Air Boxes, put on 200 cell metallic core racing cats from PLM and a new tune from Eurocharged with the "secret sauce" so I'm excited to see what Saturday brings. The good news is I found a RennMotorsport $85 for 3 pulls. Scheduled this Saturday.

For some reason every dynojet in riverside is for private r&d only I even had the ***** tonask aFe and K&N to use their dyno they politely turned me down as their dunks aren't meant for commercial use.

BadCompany

Glad to see you found another dyno. Too bad you aren't returning to the same one. Regardless, looking forward to see what your changes get you (especially with the unicorn tune). Be sure to ask for all the info from your run (temp, barometric pressure, humidity, correction factor, etc.). Good luck.

JQuala

Checklist:
Dyno mode, TC off, 4th gear or 5th?
im planning to do 3 three runs
one baseline stock
one on my current tune
The folks at Rennmotorsports were nice enough to allow Eurocharged to review the info and construct a new tune relative to the results.
Last run with new tune. I'll report back with the results

BLKROKT

Looking forward to seeing if the AFR changes with the tweaked tune.

BadCompany

Most people do 4th gear pulls, even though I think 5th is 1:1. The problem with 5th is that the speed gets quite high and some people hit the limiter. 4th is pretty close and I think the people that have done back to back 4th and 5th gear pulls say the difference is in the 5 whp range.

JQuala

here we go!

JQuala

so I'll have results posted real soon I'm still at the facility. I finally had a stock run at 415hp.
i flashed eurocharged v6 with sauce it was pulling 412. AFR was altered so we know the flash took affect but I wasn't making anymore power.
i tried re flashing to v6 without sauce and it made 410 to the wheel. Keep in mind, I have full bolt ons, kleemann(super sprint) LTH, Row air box Afe filters, 200 cell racing cats, and agency power cat back valves open on 91 octane. We're baffled!

JQuala

What's crazy is I tried 2 EC tunes and the stock. We made essentially the same power across the board. AFR changed, Timing changed with the secret sauce but not making anymore hp. I'm stumped as ****.

BadCompany

That's crazy. Have you spoken to EC to see if they have any ideas? Do you have the number with SAE correction? I'm surprised all of your numbers are uncorrected (not that it explains what is going on, but it will make it easier to compare with what most people see with those modifications).

BLKROKT

There is no correction at those conditions. That's right on the SAE benchmark across the board.

BadCompany

Ah, you're right. It's almost dead on. I missed that looking at the mobil version.

JQuala

Can't find a thread with similar issues...it's as if no matter what I do I'm stuck at stock hp

JQuala

He's suggesting me car is running dangerously lean. I got sent all my run files as.w8a files so I don't know how to upload to mbworld without my Rig but I can't use it since I sold my 6950x for a 7900x without a motherboard. The graph I posted may be very confusing as some are run at 1:1 in fifth but most in 4th. RUN 1-2 are stock the rest are between the two tunes from EC the two 415hp runs involves one stock and one with EC secret timing sauce. What do you make of it?

DavesMeanE's

Ya something is deff wrong with your car...

Gotta get that figured out - no tune can fix a broken car.

I'm happy to assist if you'd like to PM me directly.

Thanks!

Dave

thesaintusa

Clogged cats?

DavesMeanE's

Do you *** Actually*** have ROW airboxes? Or did you cut out the charcoal filters? I've had plenty of "DIY" airboxes cause problems.

Don't be cheap...

Thanks

Dave

JQuala

I have actual row air boxes from ecs and my initial dyno results were ran with straight pipes. My second visit to a dynojet facility had my RC installed and nothing changed so I doubt it's the cats

JQuala

Serge found stored codes for faulty mag sensor(that I had already replaced) he took care o f the codes and reset adaptation so hopefully that takes care of he issue other than that. He said it looks good
