Post Your Dynos Here Ii

[IndigoBlueWagon]

It's a very conservative dyno. The A3 will effortlessly run up to 100 MPH and beyond in 5th. It feels faster than the numbers indicate.

The numbers don't really matter, it's the trends I watch.

That Dyno does not look right at all. That dip is awful. You figure out what is causing that?

 

[mojogoes]

The turbo!! ^^^

Yea it was a kind of bad on the street, but way worse (terrible) under more load on the dyno. I really just posted it up to show what you can do on a BRM with stock injectors. Just replace that dip.... with a straight line and its not a bad graph. I never did get to dyno that setup after getting the revised tune in. So that one is the only one I have.

I set up the Boostvalve to fix that issue right away, but Yes it was fixed with a series of tunes and logs shortly after that, so yes it was the tune, but the actuator could have been set up a bit better from the shop. (but that is besides the point).

With the S/t 1952 turbo I have now and a good tune, I make about the same power (but dyno only) and zero smoke ever. I have never dynoed this setup and do not plan to, as I will replace this turbo.

The turbo!! ^^^

Im sure it contributed to the issue, but how much I will never know.

If that last dyno is accurate then it must be the absolute limit of the BRM injectors. The stock file requests over 40 degrees of injection duration!

We all ran on that dyno at a GTG, so we know that it had a baseline that is quite accurate, that is why I went back there to dyno again.

I could still even get some smoke with that tune at WOT. That was with the stock cat on it.

That's the thing, when you extend the injection interval too long it will just start smoking but not making anymore power (it also drives up EGTs).

 

[mojogoes]

Correct ^^^ but if you throw in some larger injectors you could cut down on the injection period/length and make more power in half the injection period depending on how big you go................ok maybe not half the time but oe or slightly less you get the idea.

 

[creep]

Here's mine... 110hp with a re-map and sports filter. Now around 140hp.

Are you kidding, it's obvious it popped a boost hose - hehe.

It could also be a clogged fuel filter, bad lift pump, or bad fuel too, but I really doubt it. I would bet a steak dinner somebody forgot some mapping changes in the tune ;-0

PD100 injectors are not a limitation. Simply look at your vaglog data for a wot run (1, 8, & 11). Compare your tuned values to oem. A huge torque/smoke map with give big delta pedal, but quickly settles back to oem request with bad mapping ie. a missed drivers request map or oem 02 sensor calibration ;-)

[mojogoes]

I'll go with the "oem 02 sensor calibration"

 

[KROUT]

what would it feel like when driving if the o2 sensor calibration is off.

 

[jsrmonster]

It would feel like oem falling on it's face at higher rpms, kind of like the graph shows.

This is the problem with tuning boxes on edc16 cars. The O2 sensor needs to be considered too! If not the car will detune itself over time to satisify the oem 02 allowance (with correction factors).

I've finally found a great Tuning Box solution for the edc16's (that copes with the 02 sensor compensation), while searching for the best 09 edc17 CR tuning boxes! I will be dynoing these TB's on my cars and will post results. The coolest thing is that I am able to custom tune these boxes myself so they can be made to fit hardware installed in your PD. ie. 3bar map, big maf, and injectors (for edc16).

It's nothing like that. I did still increase injection duration slightly but if you go and add 5 degrees to it or something then the James bond smoke starts pouring out the back. (I didn't do this guys tuning if you got that impression). There is also a bit to just shut off lambda adaptation altogether.

 

[Farfromovin]

James bond smoke-- ROTFLMAO

 

[SBAtdijetta]

Right, and it may have been too long, thus the smoke and high EGTs on that tune.

No, nope, and no. But yes on the mapping of course/obviously... Swapping the tune, fixed the issue.

I'll go with the "oem 02 sensor calibration"

Well it may have been this... it was all in the tune as you say.

dyno yesterday at DSG

I put the car on the rollers yesterday at DSG is a 2001 jetta with BEW engine, big a$$ R32 brakes and wheels and RC4

my mods are on my signature:

[Sootman]

Here's mine for the Mark 5 Jetta. Small dip apparently is the O2 sensor. Jeff has a fix but there's no rush.

I'm happy with the numbers but more so with how the car feels. BTW there is NO smoke at all with this car.

 

[delvi__acevedo]

Soon to start a 12-step program for myself and others known as "Modaholics"! There may not be a cure, but there's hope

Delvi,
Thanks, I'm thinking of going to a monastery and ponder the problem. True acceptance will take some time. I still want a ride in that beast of yours! I can't believe I past it up last weekend. Not only does it look good but great numbers too.

Steve

 

[delvi__acevedo]

Thankyou Steve, I want to drive yours, maybe we should trade for a week

Is that at the crank? If not how high are your egt's? Nice numbers for a vnt17.

I don't know egt. I know there are more with this kind of setup and as far i know no problem.

I think the curve looks pretty decent! Now you just need to up your air mods a bit and an RC5 upgrade!!!

 

[mikeyF]

cool wasn't sure about the curve, just because the 3rd gear curve was soooo smooth. I watched the boost spike to 23lbs for a little bit, then settle down to 19lbs... and this is on a stock fuel pump with no lift pump either. I think it's tough to compare #s when people run on different dynos at different times...

RC4 is in the works this weekend I hope

Exactly! It is tough to compare your results to others from different dynos in different atmospheric conditions, etc... The best thing to do is go to the same one over and over while upgrading to see changes that matter to you. Numbers are almost meaningless IMO. They're nice if you get the ones you want, but they don't offer a fair comparison to others setups.
