Well, that was interesting. The folks at Cobb had a heckuva time running my car due to the tranny thing. Unfortunately, They wouldn't allow me to drive so that made it tough. I don't really know if I can use the data for much but I will send it to George and see what he thinks. The tech had such a hard time that he didn't even charge me a dime so I guess that's a plus. I aplologize for the poor quality of the scan.
Basically though: Boost is off big time. If you superimpose numbers along the AFR line, starting at the bottom with zero and each line is 3psi, you have the relative pressure. The AFRs are lean and there is a weird dip at 5100 rpm.
The numbers at the bottom are min. max. and average.
Max HP is at just over 13psi. so much for my 19 psi RICA tune.
Max torque is great but at 3000 rpm and still only 17 psi.

I should add that this is uncorrected and at 4200ft. MSL

I have some other graphs that are screwed up as well, one made 228 HP but in general, I seem to be way down on power and boost.
Flame away, I know I have work to do.

No flames, just a lot of told you so's. Good luck with fixing it, love these 'tunes...'

[TorqueSteer]

Yeah a typical modded volvo, dissapointing at the track and dyno. I went though the same crap until I just gave up with benchmarking.

[y2blade]

gutted for you, good luck fixing it buddy

[turbor850]

yuck, geez . . . . .

thats all I have to say . . .

[turbotuner]

No flames, just some advice...

Before doing anything with the map, you have to make sure the mechanical bits are fine. Otherwise you are just wasting time.

Start with checking the boost because it's easy to do. Bypassing the ECU boost control will quickly determine if there is a problem holding boost at high rpm due to a mechanical problem.

Hmm... that doesn't sound right the (whp #).. did they do a 3rd gear pull each time? Also is this on a auto tranny?

I feel for you bro. Don't be upset, this is great data. Just by rebuilding my turbo and adding a less restrictive DP, I gained over 25whp. Get all the mechanical stuff down. Then try again.

I'm doing a pretty serious build and I only expect 300-350whp. I've pretty much ruled out the 19T. The exhaust housing is too small. Torque Steer let me know how a larger exhaust manifold is a must. I strongly agree with him. When I rebuilt my turbo, I held that TD04 in my hand and thought, this thing channels all of our engines exhaust gas… No way.


On this side of the pond, it's hard for us Volvo guys. Tuning is an issue. Parts are an issue. Most of us bolt stuff on expecting to get more and more. Unlike JDM, Nismo, and others we are at a huge disadvantage. Off the shelf tunes are just that, off the shelf. We need experienced tuners and flexible tuning solutions. We need to open the cylinder heads and flow path of these engines too. Large turbo, forged internals, a nice open intake path, open head, 3” exhaust, high flow exhaust manifold, a good amount of fuel delivery and a GREAT tune is the only way to get the nice numbers we all want. I didn't even mention drive train. LOL

With a shelf tune, injectors, open exhaust and a 19t, you can get some basic power. Don’t expect too much though. Going back and forth with tune by mail is a crap shoot. Look at what others put down with your set up. You can get a better idea of what you can expect.

What are your power goals?

This is pretty true, tuning is an issue, but at least some of us in the N.E. have a good dyno tuning shop, im surprised nobody has looked for other Audi tuners in their area to take a look at volvo maps. I mean the 4.3 is basically the older S4 maps, so I don't see why a good experienced Audi tuner wouldn't be able to do Volvo. Exhaust manifolds are good if you have the money, but just porting it is good for around 350 + whp, which only a few are even able to get. And even then, the stock pistons are good for 500 hp . . . I think the Volvo crowd should be pretty content with whats offered, I mean 5 years ago there was chip, exhaust, and that was your options

[VolvoWill]

Unfortunatley I have not made it to the tuning part of my build but I just plan on runing standalone with a dyno tune. I am friends with a guy who does some of the best tuning for Subarus and Evos on the east coast. Im not saying he is the best but he does have people travel to him from all over just for him to tune their cars.

[cr854r]

sorry for the noob question, but how do all of these mods give your car less power, i just ordered an ipd tuned ecu on my r i hope im not throwing money away

I don't really know what other mods to do. I recognize the 19t has limitations but if you read my sig you would see that the motor is done. Compression is fine and equal. All the "mechanical" bits and pieces are there. The folks at Cobb (who deal almost exclusively with Nippon Denso ECUs) feel there is a timing issue, as in a lack of advance. They couldn't Data log any of that however and I will be looking for a way to do that.

[Chilled Man]

only 222hp ?

what the hell is broken ?

you shoudl be doing that stock

[bigmay850]

Isn't there a tread about an ecu from UK
with data port?
hope you work out all the kinks!

i agree. i was dynod once before i had my tune at 13psi with an intake, exhaust, and RIP and i was at 219, and that was on a 16t. i'm not trying to prove a point, but i am eager to see what the potential is of your setup. i know it's good for more than that

[loseR99]

I seem to be way down on power and boost.

More like boost, then power. I'd look into the boost control. If you're on the oem solenoid and its tired and old, you probably won't hit that 19psi in your tune, and if you do, it won't be for long. Control your boost, control your power. You made nice torque, 341 at the wheels, just didn't show you in HP what you really had since the boost faded so quickly and inconsistently.

If you read the albeit poor chart, you will see that the 222HP came at 13psi. Which by the way, proves a long standing argument that no matter the size of the turbo, the same level of boost will provide the same level of power all other things being equal.

Also, the tech wondered if the hicup at 5100rpm was the knock sensor shutting off. Does anyone know if that is as designed?

I wasn't just talking about all the mechanical bits "being" there, I was talking about them being setup correctly. Have you had the engine apart or changed the cam-belt? Are the cams setup ok? Is the turbo contol working ok? Is the turbo itself ok? Are all the sensors working ok? etc.

First you should check the boost level at high rpms by bypassing the ECU boost control. If it won't hold boost with an EBC or MBC etc, then it doesn't matter what you do - you will never get the power.

i read your chart and that's the reason why i posted what i did.
