Well....if you have your Tactrix interface plugged into the OBDII port, not only will the screen demist, it will also log the event for you!

Note: you can also have RPM/Load on/off triggers etc. I just like the demister

back on topic please boys...I believe Jono may in fact have some good news to report but I will leave it to him to post.

Thanks Dave.

I'm not sure why everyone got into Mao for, I asked him for those dyno graphs personally just for my own records.

Anyway, Sean got into my car today for his turn at trying to tune it. I think he forgot to put my initial run in as we did it about two weeks ago so i'll have to try and hunt that down, but I have dyno results below for today's tune.



He told me to come back in about a month or so when there's an update in the software. He wanted to increase my boost slightly to make a bit more power but didn't have the parameters to do so as yet. Car feels a lot more lively now so it'll keep me entertained until i take it back again.

So I guess now I can assume that it wasn't hardware in regards to the Martin Donnon tune, so I wonder what it was that made it go so wrong?

Good to see you're making some progress Jon.

Pleasing to see some progress for piece of mind sake Jono.

Seems to me after reading and research that the MY11 WRX and Forester ecu tables are significantly different to those of the MY10. Open source definitions and reverse engineering is the issue I am guessing.

My question to Sean would be what parameters were you able to change today and which ones specifically weren't you able to change ?

Yea, a bit over 1 bar or 14.9psi is a little on the low side, 17 or 18psi would be getting closer to the mark and should see you getting close to 270awhp if not a bit more, should make it a rocket.

That's what it's all about Enjoy.

^ I was just about to comment that the power was lower than I expected.. but yah 200kpa will do that too ya. Looks like it just keeps pulling too, would love to see the torque graph

It looks like its running almost standard boost in that graph. We were aiming for a more conventional WRX tuned boost curve, hence if there is a software/hardware problem - we ran into it. Good to see you got a result though - that is the important thing

OK, most people would have thought id learnt my lesson from the first internet tune attempt but with some help from Dave, i found myself another tuner, Eric Minehart from Torqued Performance in the States.

At $120 USD for a "custom stage 2 tune with EBCS", I thought, why not.

From his very first file that he sent me, the car had no issues with the new tune what so ever. Issues that I had with the first tune were no more.

This was the result of the dyno yesterday.






The first run was the best, the second and third we had issues due to cooling limitations.

Run 1: As stated, no issues.

Run 2: The tune ran rich, we presume this was because there was extra heat from the engine and the restrictions of running the dyno fan over a top mount intercooler. We are guessing the ECU added extra fuel to compensate for the higher intake temperature.

Run 3: The ECU pulled timing, but maintained boost. We presume the ECU was trying to prevent detonation. Car detonated at about 4500rpm. Again, a higher intake temperature and setup of dyno fan on a top mount intercooler can be considered.

I sent an email to Eric, and he replied as so:

How close where the pulls together and was there any kind of fan on the intercooler? If there wasn't adequate cool down between runs this can happen.
It has been my experience that the dyno doesn't always represent real world conditions. Not only is there no airflow over the intercooler but the engine is working hard without airflow. It is unlikely that this type of situation would occur in the real world. It is my guess that the intercooler was much hotter than it would ever see in the real world even when outside temps are 115 degrees and you are sitting at a light or in traffic. Even so the intercooler will cool down when the air starts moving.

So, thoughts?
