Where are you located? I know JR had tuned a few on here, I tune myself now but I've found local shop that specialized in standalone engine management who have tuned me in the past. No plans on tuning yourself?

I'm in south florida (Fort Lauderdale) jr is our tuner
Not sure he's going to tune it tho.
I started to look into it but it looks complicated to me.
All the configs etc l, I have a Sti engine in a 2002 Wrx with AEM V1 in it
Will see I might go with Haltech elite 1500

Never messed with Haltec software. Do you think that would be easier to configure than Link?

I don't but there is a very reputable tuner called
Crispeed (kris) working mostly on Evo's but he's a Haltech
Guru by what I've heard, if I had one for Link I'd go with it.
I'm learning the system tho it's packed with safe features
Long time learning and all basically it'll be hard to be lean
Or knock with the Haltech.

You can blow anything up if not setup and tuned right. Any engine protection strategy is only as good as the understanding of the tuner. If your tuner is a Haltech Guru you'll probably get better results faster going with what he is accustomed to but don't think just because of that its impossible for something to go wrong and for you to get in a lean condition or knock under the right circumstances. How the ECU handles those circumstances depends a lot on the tuner.

Bump from the dead.

Is anyone who comes around here these days running a Link?

I am trying to get to the bottom of a statement my tuning shop has made a couple times that I question...

They quoted me a 20-40 WHP increase from the Link ECU alone while changing nothing else on pump gas.

They showed me a dyno sheet of an EJ205 with a VF39 on a link ECU making 300 WHP and 300 WTQ when my car made 250/225 on the same dyno, on the same fuel, and same turbo...

Trying to make sense of it all....

I've been told by another reputable tuner that power gains from ECUs alone are impossible. I know the 16-bit ECU is super old but can it really result in that much gain?

Any Linkers?

Usually going to aftermarket ecu includes going speed density. Thatís worth some power. I also think we have less than perfect control of avcs and fuel with a couple of things still going on in the background(egr fueling ect). Iíd say a mew haltech is worth some power over my merpmodded speed density flex rom. Donít know on link or 16bits

My car doesn't have EGR or AVCS.

And it's hybrid tuned on SD and MAF right now.

I meant evap, my point is we donít have as good control of our modified oem roms as you do with an modern aftermarket ecu.

Yeah true.

I know the features and control is better on the standalone, I am mainly asking in regard to direct hp or torque increases.

My tuner says 20-40whp. A reliable Subaru tuner I trust says hp gains from ecu swaps are not possible.

Who to believe....

Upgrading control/refinement could net some power gains. I could see that. I wouldn't expect anything earth shattering.

You'd find more if you instrumented for individual cylinder trims.

Fair point.


I may weld on individual wide-bands per runner when I go big turbo with the 3576 G2 I have.
