Hope these are ok for you, this is our 2004 Liberty GT 2.0ltr Auto.....

Hey,

Thanks. I need to convert my reading to kw. I tuned a couple of auto, but ended up just making the car run better. Dynoing was a little pain. Lol.

[tangcla]

Curious to know if you've tuned an auto 2.0T and what gains you can make of the AVCS

[west_minist]

Honestly, I never really did get change to tune the AVCS like in the MT, but extended it into lower RPM. Let me see.

Ok. Did some minor increase, but not how I work on the MT. I would expect the same results, with a better spooling turbo, because of how the Auto works.

I can resend my 2 of my customers updates on the AVCS, but its xmas time.

[west_minist]

I did the conversion. Same as your kw, but i am not sure of your testing environment, but it was hot here, where we saw temps at the Intake from 40-32C

Hope these are ok for you, this is our 2004 Liberty GT 2.0ltr Auto.....



Cheers,

Here you go. I sent him a new fuel map to see what will happen. Will post results as soon as I get them.

I find my software dyno reads up to 10points below actual dynoes. What I can tell you, the car feels close to a stock STI 2.0 with just an axle back.

Tire: 215/45-17
Weight of car: 1568kg
Temperatures: 28-29C, done at night
Mods: Full turboback, Panel Filter
Issues: Leaking bov

Stock 4th Gear vs v21 4th Gear Dyno

Those low down gains are very impressive! What do you contribute most of that torque increase to - bringing on boost earlier or AVCS tuning?

Also, how stable was the factory tune on the petrol in Trinidad before the tune? i.e. did you actually pull much timing overall to reduce knock before increasing the torque/HP etc?

Both boost and AVCS. AVCS was the big gain. I resend a new rom with fuel and more avcs for review. I will see what the max avcs can be and the gains. Everything remain stock.

Not stable at all sir. Car spent more time running on wastegate boost. That is 9-10psi.

See a similar car, but its quite normal with legacies.

Well, yes you have to pull timing. I drop in a new rom for tuning. Never use the stock rom stock paramaters, except the timing. Stock is only log for baselines. After that, a full rom replacement with many changes, except for ign.

I think fuel is 92-93 octane, but can be fairly inconsistent. We weren't running octane boost in this one. I requested another log with it before switching to the new rom.

The low gain and flat tq curve is great for cornering and drifting. I have yet to drive it to feel it. Hopefully I can travel again there.

I really cannot wait to see the results on the new rom. I want to make sure I can increase response but up to 2x. I would be happy. Reason being: To decrease spool time, increase boost response, affect top-end power and to also increase low-end torque as much as I can again.

[Hotwire]

Wow - those logs look just like mine - total rat shit! LOL

Hrmmm, well seems the 2.0T Legacies/Liberties were just completely poor tuning from the factory....

Well, its JDM. Shouldn't have left Japan

But now, its clean and we are happy Just need a AVO TMIC, AV0 BOV and a STI vf37 and injectors. lol

Well good news from the customer. No logs yet, but so far, he has stated an increase in turbo response, quicker spool and enhance lower end power. In general, a responsive car. Not sure on the combination of low end power as quicker spool and avcs was added. But so far he loves it as he stated that its like having new spark plugs in. Will keep everyone posted.

So Edward sent me a new map last night, I am still grinning. Let me say 1st, the previous ROM worked quite well, so any improvements on this ROM to me (the driver) is very good. Now, the car's response is phenomenal, throttle response is INSTANT, torque is even more noticeable at low RPM. The 1st time I drove on this ROM I felt a little scared as the car literally felt like it was running away from me. She is very fast and very responsive, above 6000 RPM feels like it still has power. ROM still needs to be tweaked as I found a few rough spots here n there, but negligible and nothing for Edward to sort. The car runs through the RPM band faster, in 3rd I can go from a low 40km to up to 120km in very little time. I need a co-pilot now to log times, or maybe hit the tracks for time trials.

v21Fuel(red/blue) vs v21

[west_minist]

Ok. Did some changes around 2800-3200 range and also at the 6000rpm mark. May extend it more as she is working very well over 6000rpm making power, which is not the normal for a small turbo and no other mods. So the addition tuning is working well on engine and just replaying the logs, you can see how responsive the car is compare to previous roms, especially with a leaking BOV that really needs changing.

I think I am happy with the fuel and more can be done, but I think I am happy with it and I know the customer is even more, as he do not drift or drive the car hard every day like some of us, but his fuel economy should look way better now

Due to gas quality, we run close to 17 degrees to the redline, but if we had atleast 95 or 98 octane or even better, water injection, our power can be even be more as we can run more Ign. If I can get him on Lucas octane which is better than NF Booster in the black bottle, we maybe able to run up to 4 degrees or more and just see even better response and power. But such dreams are not reality

But once the customer is happy, that all that counts people.

Email:

Norm is very very responsive and fast, lol. I swore I heard 1 or 2 back fires, but I am not sure, I was so high on the power! On that note, I dont recall running any gear in NORM from low rpm as it was so nice n fast, lol.

Above is all true, since we went from 102kph to 223kph in a flash. It was not like yeah girl, go go go. It was like, woow, let me run 5th gear out. At present, Injector Duty is under 80%

I can post the speed graph, but I think its useless. Would see if the customer can log a video on some drag runs.
