UTEC/ECUtek/WI & SD tune

Default Tune, Fuel, PDX and Alberta

OK the short version

My car tuned by Jarrad from PDX 12th May on 91 octane Esso from Bonavista station in Calgary. Jeff S, Tim B, Jeff P, Forrest etc were present all thru the night till 12.30am as were 15 others. Pizza friday

Base tune was first on Ecutek then with one of a kind special UTEC sauce then water injection.

First off the numbers below ďdonítĒ mean squat except that WI increased torque very nicely.
The tune was for road racing not for any of you Dyno number queens or drag racing. Iím sure on the Edmonton Dyno I would get over 500whp.

From Memory
35 Dyno pulls and 5 hours of tuning with maximum boost of 18psi because of the 91 octane.
Ecutek got 285ft lbs and 316whp at 18psi
Ecutek with UTEC a little more at 18psi because of consistant timing
Ecutek with UTEC and WI got 306ft lbs and 328whp at 18psi
Jeff S who never BSís says thatís a little over 400CHP

Water Injection increased ft lb torque at 3200 rpm from 272ft lb to 300ft lb and held to 5200rpm where it was 306 ft lb.
What this means is the car will light up all 4 wheels out of corners in 3rd gear from 3200rpm using the sticky STI tires and yes that's in Calgary.

My tune allows me to increase octane and just tune up the boost for more power. At 20psi MAP which is in the greens sweet spot at this altitude and Husky 94 the car is quite fun but the clutch I sure is going to beg for mercy.
Ask fragment any questions on driveability and power as he has driven it and had problems over revving while in the first 4 gears. Guys gotta learn to change faster.

The car drives smoother with UTEC special sauce than with Ecutek. UTEC will rule once more. The stock ECU certainly likes to play what's my timing this run and as such the UTEC is so much better.

The car has 5 maps
0 stock Ecutek
1 UTEC 91 safe
2 UTEC 91 WI safe
3 UTEC 91 super safe
4 UTEC 91 WI super safe

Almost a month and everythings still very good.

Now onto fuel, tuning and Alberta and some things to ponder IMHO.

Husky 94 is better than any of the 91 octane fuels in Calgary just donít mix toluene etc into it because Iíve found it to be funky when pushed.
Esso 91 is the most consistent 91 octane year round Iíve found
Everything else except Shell in Calgary is OK year round except that winter gas is all over the place and a conservative tune is most definitely suggested.
My EGTS with any of the fuels and WI hit 1680f at the top of 5TH gear. Portland racers see more at the circuit. Darthchicken with 400whp runs 1750f and has been for over 2 years. Yes I talked with him the night of the tune, nice guy too.

Tuning your car in Calgary requires either a very conservative tune or constant retune because of
The temp changes because of the cold and Chinooks
Calgaryís constantly changing altitude correction factors
Winter gas

Conclusion
For the first time since I have owned my car I'm happy with the driveability. It now drives way way better than stock, silky smooth with effortless easy power all the way to 7k where maximum HP takes place.
Thanks goes to Jarrad and TurboXS rush delivered special sauce.

So would ou say its OK to run 93 maps on 94 fuel? Sounds like it to me.

Thanks for the narrative. Very informative. JC

Be careful as I have only tested Husky 94 against Alberta's 91.
I did use Chevron 94 in BC and found it to be a just a touch better than Husky 94 but the test was only a few weeks back and very very limited, winter etc is a whole other animal.

Knock detection and a very easy way of adjusting boost is your friend.

Husky doesn't change the 94 formulation in the winter do they? The cold air should give you a little safety margin from the lower IAT.

Mother nature is the issue.

Altitude correction factors can have Calgary from 1000ft upto 7000ft. Add very cold -30 temps with chinooks.

IMHO tune for 91 and use Husky 94 for safety

That's the plan. I need the 91 map for travelling anyway and I'll get Jarrad to keep it conservative...never sure what you might get in small towns in Saskatchewan. I will get a 94 tune as well just to see what the 3" green can do on a Legacy and will run it in the summer. I'm going with the Dtec boost controller so I will run a lower boost map 90% of the time and will set the scramble map up as high boost for when I want to have real fun. The Dtec also comes with a knocklight to keep an eye on things.

Are you running a standard inlet green or a 3"?

It also depends who's map's you're running. I'd be carful with stock CObb 93 maps. My high octane map is from PDX and I made sure that Jarrad new I wouldbe running Calgary 94 which he is familiar with. I have datalogged it a lot and everything looks great. Every car is different though. I agree with Wombat though...you need either knock detection/display or else datalog it regularly under all conditions.

Just curious that's all. When do you hit full boost on yours? I'm going to be installing a 3" inlet green in a couple weeks and it would be interesting to see if there is a noticeable difference. The difference between the STi and LGT intake manifold could make it a tough comparison though. I'm also porting my TGV's to clear the bigger inlet tube which could be the cause of the increased spool and power a 3" usually shows.

I also just noticed you're running an EWG...so much for a good comparison

We'll have to get together some time to compare greens.

If it makes you any happier the PDX dyno reads within 5hp of the Monica heartbreaker Dyno they used to use. Torque is way different thou.

Jarrad asked me up to Edmonton and if there's time I'll do a pull and get 500whp on that Dyno on 91

I do for FWIW get the same power or more up here as I did at sealevel because the turbo is right in its sweet spot.

Peak power is one thing but 300ft lb at 3200rpm with WI makes for one quick road/track car.

I shift just fine thank you. I'm just used to shifting at 8,000

I can verify everything Wombat says about driveability. Very smooth. Deceptively quick since the torque "curve" is more like a table top.

But now I want more power. More than I have now, and more than Wombat has

Did someone say GT35? No, I think a GT30 would be more the way to go.

But if that doesn't do it, I'm going to have to midnight auto someone's 2.5 shortblock

I think I'll download ECU explorer and start datalogging PetroCan 91 and then Husky 94... on 91 maps. To get some baselines. Then I'll move up to Cobb's 93 map on Husky 94 and see what I get for knock.

So if you ran 94, would you be able to get more power with only a slightly more agressive tune?

I need to get a ride...

I've been running Shell V-Power 91 for the last year or so (I like the AirMiles.)
I have nothing to compare to, nor do I 'know' what knock sounds like, but it seems to have been running fine the whole time.
I've never heard what I thought was knock. I've tried a tank of Esso or Petro-Can here and there with no discernible difference.
My peak boost (as shown by AM Nexus gauges) is consistently about 16.5psi in gears 3 and up.
I've read before that Shell gas is not great, but those are old threads from before Shell introduced V-Power. Is that still true today and on what is it based?
Maybe I should switch brands before the ProTune. I'd go with husky 94 except there's none near me - I live/work on the east side/Sherwood Park.
What do you guy think?

make the drive for the 94! but as for the knock you'll know you get it when your check engine flashes.

mark, sounds like a really good experience and i hope one day my car runs that good.

Where are the Edmonton Huskys with 94 again?

3 in the West End, one on St. Albert trail, one on the south end of Calgary trail, I think. Any others?

There is one on 153 Ave and about 73 ST I just filled up there last night. Felt it was time to try it out now that I'm stage 2.

I think they're talking Edmonton.

That's good news that there are Husky's with 94 in Edmonton so I don't have to haul jerry cans full up there.

You will need empty jerry cans to empty your 91 octane or 94 for the different tunes.
Note you will need to break into the fuel return line to fill the jerry can and let the car die. Quickest way to empty the tank once connected to the return line and filling the jerry can is to turn on the ignition for 30secs and then turn off turning straight back on then 30 secs repeat. Why! the ecu cuts the fuel back to a trickle after 30secs and you will be there along time.

Breaking into the return can be done at the fuel dampners. Just use 2 small vise grips and pinch the hose. Undo clamp then pull off from dampner then install barb with long fuel line to jerry car. No fuel leaking all over the place on hot engine parts

FWIW All I have to do to go from a 91 tune to a Husky 94 is turn up the boost. Since I'm using WI life's good.

Also the green is a noisy turbo but no one seems to care. Garrett's are quiet as stock.

Wombat....thanks for the tips. I hadn't thought about tapping the return line. Sounds like we're going to have an our between each octane tune we want so I was thinking about just heading to the highway and burning down the 91 in the tank and then filling with 94. Shouldn't take too long if I hit the dyno with less than 1/4 tank. Your method sounds a lot easier with less chance for tickets though
