Follow the link... 3.6R stock did 0-60 in 7.60sec and v1 tune 7.41. There's a v2 tune but no results as yet.

Just interested if this is a direct or indirect CVT tune? i.e. are you reprogramming the CVT or just making adjustments to the ECU parameters/tables that are used by the CVT?

Yes I was tossing up whether to fit RE050A as I do think they are a better wearing tyre, though the guy at the Bridgestone shop said that they'd got 50,000km out of a set of RE003's which I find a little hard to believe but I guess we'll find out soon enough!

Bridgestone RE003's are quieter than the Goodyears, however I suspect the Goodyears will have a longer life. Time will tell...

Just a small update - since I haven't posted anything for a few months. Had a set of Bridgestone RE003's in 245/45R18 fitted up today. My Goodyear F1 Asymmetric 2's have served me well for the last 40,000km / 25,000 miles. I think this is reasonable for a set of performance (summer) tires. Though both of these are a massive improvement over the stock tires we get here (Dunlop SP Sport Maxx 050) which lacked grip and would squeal when pushed.

That or maybe that they were a more square profile. The corners of those look quite rounded whereas a lot of off-road/mud/snow tyres tend to be a bit more square.

Check with an online calculator: http://www.willtheyfit.com/index.php?width=225&aspect=55&diameter=18&wheelwidth=7.5&offset=55&width2=225&aspect2=60&wheel_size=18&wheel_width=7-5&offset2=55 The speedo error will be 3% - generally recommendation by most tyre shops is to keep it within +/-2%. Also you may have to be careful with your insurance as some companies won't like it if you put on under-size or over-size tyres.

The comment around updates of custom tune files relates more to the complexity of keeping a large number of individual files up to date. The more custom files that are written, the larger the job to maintain these files. I'm not saying it's impossible, however it does become a larger job to maintain and keep all the files up to date. There's no one way that is necessarily better than the other as there's plusses and minuses for both ways of going about tuning and updating tune files. I'll look forward to seeing what kind of results you can obtain from custom tuning vs. applying a "generic" tune file.

Robbie, Don't stress yourself out. What you have here is 2 different approaches from 2 different tuners. There's no real wrong or right way - just a different approach/philosophy. west_minist/XRT will tend to spend more time developing custom tunes for individual cars. He will get people to log their cars and then adjust the tune based on the logging results. throttlehappy/Matt will develop a file on one car (or number of cars) and then use this file as a template and apply this across all of the same model car. When he improves the file he will then send out updates to everyone to get the latest/greatest file. This is probably an over-simplification, however this is the basic difference (as I understand it) between the 2 tuners. There's obviously variations in the base/stock tune file depending on region and software that gets loaded from the factory. The way the factory/manufacturer operates is more how TH runs - everyone gets the same file and when an update is available, everyone gets the same thing. There is a case for custom tuning - particularly if you have non-standard hardware installed. You end up with a tailored tune, however you will potentially lose out on later updates/developments. No wrong/right way just 2 different approaches. Factory/manufacturers obviously apply generic software for all of the same model car. It's a lot easier to maintain software that way. Though there are arguments that custom tuning will get the most out of every engine, however only if the tuner is good enough and prepared to dig deep enough to extract the last few hp. Arguments about which tuner is better than another or which approach is better end up like a pissing contest - hence the popcorn

These look awesome! When are they going to be available? Pricing? Also I'm assuming that this requires dis-assembly of the headlight housing? Keen to get some more info as this is one area that the 6th gen falls down. The stock illuminated C strip can't be seen/used as a driving light in daytime and at night you have to use low/high beams so effectively it's useless.

+1 Get back to last known good state and go from there. It sounds like the ECU is going into some form of protection mode where it's limiting the power. I had this happen to me after running a bad batch of fuel and the only thing that fixed it was an ECU reset.

It's relatively simple to remove the grill but does require you to take the front bumper off which is held on with about 20 clips.

I still don't think it's going to have E85 though

Posted in another thread but just collecting all wheels/specs here:

Haha Robbie yeah but how many tuned 3.6's are there out there? I think you guys will be pulling low 6's for sure. A friend of mine had a gen4 3.0 wagon running E85, headers and a supercharger. Gave the WRX boys a run for their money that's for sure! Sent from my iPhone using Tapatalk

Welcome to the club Andrew! I think this is easily the best value for money mod available for our cars in terms of bang for buck. All my results for 0-60 (0-100kph) were done in manual mode and just pinning the throttle to the floor. Even in manual mode it will shift at redline for you so no need to manually use paddles. I found that if I did use paddle shifting I'd invariably do a worse time than if I just let it shift a max rpm by itself. The best thing about this mod is that it's like you have a whole new car all over again. Much cheaper than upgrading. And it's not about making our cars faster than X vehicle, it's about making it as good as it can be. Hopefully with the E85 tune it'll have similar performance to a stock 3.6R. I'm guessing 7.5sec running on E85 but we'll have to wait until Matt finishes the development.

I messaged him yesterday to confirm the 120 mph speed limiter issue. Just for anyone that needs to run higher than 120mph of couse[emoji13] Sent from my iPhone using Tapatalk

Legacy is electronically limited to 120mph - so you hit the speed limiter.... But Matt can remove the limiter for you

Go to the tactrix website and have a look at their forum as there's discussion there for using the cable for logging and diagnostics: http://forums.openecu.org/viewforum.php?f=4

A programming cable, laptop and about 20 minutes. Cost will depend if you need to buy the cable (if you can't find someone close that has one). Tactrix cable is $200 and tune is under US$300 - depends what the current exchange rate is as TH charges in $AUD.

Not sure if they have a name yet but they're the Impreza Sport wheel. Here's a close-up showing a bit more detail: http://pictures.dealer.com/p/planetsubarusne/1322/6fcab291a99c778ae667c6f2286de51cx.jpg I originally thought they were a variation on the Legacy Limited wheel but the dark spokes are quite different in design.

Do you want to post up a pic? Are these the ones? http://st.motortrend.com/uploads/sites/5/2016/03/2017-Subaru-Impreza-sport-front-three-quarter-03-e1458751120485.jpg
