 Post subject: Similarities between XT Forester and Levorg.

Hi Everyone,

Been here a while but never really posted, I've always had WRX's in the past, but don't hold that against me!

I just had a quick question, more so out of curiosity.. The wife and I are picking up a tS Forester tomorrow and while the stock power is good for what we're after, I was wondering if the Forester and Levorg are similar enough to be able to drop a Levorg ECU into it for a minor power increase and put the tS up where it probably should be? Would it be as simple as plug in, throw it on the dyno to confirm all is good then drive away? Or is there more to this new age tech?

Anyway, thought I'd throw the question up here to generate a bit of discussion, these FA style engines are quite new to me as I've only ever tinkered with EJ's..


Cheers,

Shane

Have the ts ecu retuned for more power.

Would much prefer to keep the stock ECU as is for down the track when it's eventually sold on.

Just thought if the Levorg idea was as simple as a swap and recode for any immobilizer crap it could be a good option.

Also note, the tS won't be modded at all, keeping it stock..

You keep the original tune and reload when selling. Much easier than doing an ecu swap.

Unplug a couple of plugs and unbolt old ECU, bolt in new ECU and plug in, I'm not sure how that is harder than getting a whole new tune and then having to stuff around getting someone to reload the maps when it comes to sell....

Providing of course if a Levorg ECU is interchangeable, which is what I'm trying to figure out.

Assuming there are no issues with an ECU swap (a big assumption) the Levorg factory tune will still be soft as sh!te (running too rich, poor throttle mapping, not enough timing or boost) like most factory tunes, so it's a lot of cost and messing about for a dopey car at the end of it.

At minimum you'll need a tuner to put some hours into ironing out the bugs.

Flashing different tunes on your existing ECU on the other hand is properly easy, optimised and known-cost.

Eg my tuner charges about $1300 for an initial dyno tune then everything else you might want to do (eg further re-tunes after an upgrade, flashing back an original tune, etc) is charged at a very reasonable hourly rate.

Some of the remote-based tuners & road tuners are even better value.

Why re-invent the wheel?

Probs have all kinds of dramas with anti theft coding and such. Assuning there is no physical issues.

So much easier to plug in laptop.

Definitely retune the stock ecu. Should get a lot of gains even in stock form. Also no real reason to reflash to stock when selling. Im sure the future owner wouldnt mind the extra performance. In terms of running a Levorg ecu. You would need to have the ecu coded to the car, key and security module. And then to swap back you would need to do the same again to pair it back to the stock ts ecu.
