I had been watching this thread for a while. Finally decided to switch to an ARD Green tune, and went from m4.3 to m4.4. Wow! I'm very impressed so far. Everything seems dialed in, fuel economy is up, idles smoother, starts faster, boost is solid and consistent, and the car is much more responsive overall. Lucky did a heck of a job!

Thanks Jordan, Glad to hear you're pleased with the tune!

Isn't it weird how you have to get used to the car starting so much sooner... I still over crank mine sometimes

Why did you decide to go to 4.4 from 4.3?

[Jardim]

You get better map trim control on 4.4 plus some extras i dont recall atm. But yeah its an upgrade.

all this makes me want to build a rat rod out of the 855glt i have in my driveway

[volvo]

Lucky custom tuned me a 2.3 .57 trim setup w/ manual swap for my 98 GLT..

No check engine lights when it was run I gave it about 18psi, its tuned for 21 + 7000rpm

screamed like a bat out of hell 11.2-11.9 AF/R on WOT

amazing tune. sh#ts all over my ipd/inmotion tunes that Ive had

DO IT!

I just now recieved ARD orange tune.
My request to Lucky was better MPG, more and linear power.

I can't say anything about MPG for now, but I am very happy with the tune.
My car simply pulls harder, holds the boost better.

My car is all stock except the tune.
I higly recommend it to anybody who wants to get ECU tuned.
Lucky is the man!!!!!

this is all making me want to get an 850 again just so i can use an ARD tune.

Dyno-ed the car again (ARD Orange), after the lightweight pulley and Snabb J-Pipe install:

The shop is going to email me the images of the run as well as AFR and boost tonight, but here is the preliminary:



vs.

3 months prior.

If I read correctly that's a gain of ~12 lb/ft and 11hp compared against the previous max, correct?
Hard to visually compare the curves (tired eyes, sorry). That's with a 15g, right?
Thanks for posting them up!

[crazykn]

Both were running the ARD Orange with the only differences being the addition of the ARD Lightweight crank pulley and Snabb Intake Pipe. I did the dyno again, because I didn't trust the first dyno run (the one on paper), because of the high torque and low HP. Apparently this seems to be accurate as shown by the run I did today (the camera shot). I did confirm that this run was done in 3rd and not second or fourth gear.

My car is a 98 S70 T5 Auto stock turbo (16T), other mods are listed in my signature.

Once I get the rest of the images from the run (being emailed by the shop), I need to figure what is causing a high PSI spike when the curve peaks around 4000 rpm. One run it spiked up to 21psi and then dropped down and stabilized at 14-15psi (which is exactly what the tune is supposed to do).

[ARD - Lucky]

Make sure your wastegate isn't too tight.... that can cause spiking.

Overall looks like you picked up a few HP/TQ, not bad at all!

[crazykn]

I may loosen the wastegate adjustment, I had it set to 4psi prior to the ARD orange tune and haven't changed it since. I may also dial in the camshaft settings (once I get around to ordering the cam tool). So should I do the settings indicated on the ARD webpage for the Orange tune or should I do something slightly different? I did install the Snabb intake pipe and may install the intake spacer (sitting in my garage) soon.

PM me and I'll give you some recommendations based on your particular setup!

Isn't 210whp a little low for a tuned car? Stock is 222bhp, which should be about 190-200whp depending on transmission. I'm also curious as to why your torque is so much higher than the power. These engines in close to stock form usually make about the same torque and power, numbers wise.

Not really. Everything I've seen as far as dyno numbers shows huge torque numbers that are usually at least 50ftlbs over the max hp number. It is a function of the smaller turbine housings commonly used. Once you start adding an R manifold, porting the intake manifold, adding a larger throttle body, etc., you'll start to bring the hp number up and the torque down a little bit. My last dyno session with the last setup was about 285-290whp and about 300tq after some "flow enhancements".

Ok, well that could explain the gap in the numbers, but still, the power number seems a little low for being tuned to 14psi. A stock 850R at 12psi is rated for 240hp at the crank, which would be about the same as his dyno plot shows. Granted straight boost is obviously not the only driving factor in power, but upping the boost another 2psi on about the same hardware should net something.

The volvo turbos seem to offer the best output between 16-19psi from my experience. Also, if you have an automatic it is tough because there is more loss compared to a manual trans car.
