BL5 ECU Tuning

21 posts in this topic

So basically I just want to make sure before I purchase anything.

I'll be getting a EJ257 shortblock and fitting my BL5 EJ20Y heads to it. Just wondering/making sure that I will be able to tune the stock BL5 2.0L ECU to account for the 2.5L EJ257 Shortblock?

Greatful for any help! :D

Yes

No different to rescaling for a bigger MAF, or bigger squirters etc etc

Go forth and take advantage of this newfangled technology

Thinking brand new EJ257 with forged pistons. All the rest should be up to the powerlevel I'm after.

Another question.... I'm doubting it but wondering if the 03 BL Legacy ECU can have two different maps?

I know one of the guys on the Australian forums had 2 maps on his 512k ecu. 3.0r One for 98 and one for e85 it picked the map based on the key used in the ignition. His username is BillyCorgi. Think Matt (kido) did it for him

Been a while since I've read his Forry one bit didn't Matt have something similar with the keys for his own one. Gave the Mrs a way tamer tune than the one he got.

This sounds like the go xD

Was hoping to utilize the "Eco" button for a really economic tune, lowest boost setting possible, lowest power output possible and then turning "Eco" off would be a full 27ish psi tune :D

That would be ideal for me.

You can get a couple of different maps on the red D style with the SI drive correct?

Heck 27psi sounds higher than required for what youre after. Any medium frame gt30 sized snail should deliver at 20-22psi. High boost wont work all that well with the 2.5 even with high flowing hotside.

Can you just put a switch inline to turn off boost solenoid?

Pretty sure you can get different boost maps per setting on SI drive. Not really something you can retrofit though.

27ish. I'll let the tuner sort all of that out.

You mean chuck a switch inline so I can switch off the solenoid and run wastegate pressure only?

Yep its how i did mine when i didnt have enough inputs.

Running 98 you stand a better chance with higher boost but better to just put the right sized turbo on. Just clear turbo choice and setup with the guy whos tuning it before you buy up large.

Not really sure where to put this question but it might aswell go here aha.

Almost finished my engine build.

Question is, who's the "Tuner of choice" (Lower North Island) on here? I've had very good reviews from STM by family however that was where Andre was running the show, now that Phil's taken over I've heard a few "Not so good" things.

Curious who you guys would get to tune your build?

Dtech.

Always wondered how good they are at tuning stock ECU's as opposed to Links? Like boost by gear and other features like that not used in the stock tune

Most tuners dont even bother with stock ecus. Normally hear bad things fast if they do tune them and make a hash if it. D1style had his tuned recently as did ajt no complaints.

Stock ecu is a very capable bit of kit, would run it happily, but definately need someone with their head screwed on to look at it

So, no-one other than Dtech then? 5 hours is probably a little far for a tune.

A lot of people love to tune stock ECUs. But I agree, you'd have to know what the hell you were doing aha

The person doing the majority of the tuning at STM has been Chris Wall for at least a couple of years now, from well before Andre left.

Can't see much having changed... the only major difference is they sold their dyno and brought Phil's one down from Taranaki, even then it's just a bigger, newer Dynapack.

I would have no hesitation getting either STM or DTech to work on mine...

Feel free to pop in sometime, I'm more than happy to address any concerns you may have and talk about your build and expectations etc.

We are running a special next month that may just interest you!

Regards

Phil

Just wanted to say that I went on a little trip to see Phil at Speedtech.

We had a good little chat and he seems like a really good/cool guy. We ended up putting the "Not so good" things I've heard down to poor quality control by others and a few people I know being a little sour over the price increase of the tune.

I have no problem about the price increase (If you do good work, you deserve to get paid good money for it IMO) and I will be taking it to Speedtech to get tuned. I will give a bit of a review on the tune in my build thread once it's all done. Untill that it's a waiting game!

      Hiya, would anyone in/near Wellington have a spare passenger floor mat for a 2006 Legacy b4? I’ve looked at a few aftermarket options but I’d like to find an original. Cheers!
