Dear all:

In respect to our research and development (shown way below) on the Subaru Ascent & the FA24DIT operating in this vehicle, we are offering Stage 1 tuning support to owners with the following requirements:
  • Improve driveability with clear objectivity in engine response
  • Improve Fuel Mileage
  • Reduce throttle lag
  • Better sounding throaty engine :)

For further information, please contact us at [email protected]

Please also note I have extended a hand to Cobb tuning as Cobb's Protuner to BETA test the AP on the Ascent.

Why would it be huge? It possible that Ecutek will support. So for now, opensource is available to what I offer. For those that don't need a gadget in the car, this is a nice option for those who will never go further into tuning.

Hey Chuck, hoping you can answer some questions for me. What do I need take a copy of my stock ECU, and what will I need to update it with XRTs tune?

Best,
Rob

Please do not attempt to launch your Ascent with any type of tune (stage 1 or 2) or your CVT may be compromised!!

To be honest, I dont even see why anyone want too, especially if other tuning software vendors offers it.

I just want the fake shift bullcrap to be programmed out. That other stuff sounds nice too I guess. I had a Cobb on my 14XT, mainly so I could run the 92 gas map up here in Colorado with hopes of reducing its jumpiness. But I was always unhappy the device itself was so expensive for what's basically a branded 90's Palm Pilot... at least I resold it without losing too awful much.

Anyway this thread is definitely deserving of a walkthrough video. There's a lot of soccer dads up here who would love to tinker with the family hauler, but it's not like some used roadster we bought as garage project - "oops sorry babe I bricked the Ascent" won't fly.

Yes I totally understand and I feel the same. Chuck will post a review and other videos, well I will see. I lost them when I reset my whatsapp, but I will ask for more. Actually he is on here.

This is very intriguing! I read through your links, thank you. I guess you can call me a "soccer dad" (more like gymnastics dad), but I can definitely get behind a mild tune for the reasons you had listed above.

Can you elaborate what "Improve driveability with clear objectivity in engine response" means in terms of what the driver should expect to feel. "driveability" is a vague term.

Also, what kind of fuel mileage data do you have? I subscribe to the adage that "there's no such thing as a free lunch". So what's the tradeoff here? Less power at lower RPM? Differnt throttle map = better MPG in real world driving?

Thanks.

Not really. Driveability mean the needs to do something with ease. That can mean response and ability.

Subaru tends to run excessively right. In my humble terms to aid when modding. In addition to help make the car efficient in its operations, the more you can get from the gas. I am awaiting chuck full feedback on this until the others can join.

Touching anything with the throttle puts the car in safe mod. This maybe due to eyesight and controls. But I have not try hard to see what are the limits, but based on chuck's response, there was no need to touch it based on how the Ascent drive now. I will see if this follow for the others.

Hello,
Many questions. First let me say that I have been working with Ed, thanks to Chris for over the last 2 weeks. Ed has run many tests to see what works and what does't work. Ed is very easy to contact by our WhatsApp group and we have spoken by phone several times when I did not understand what he was asking. I am not a tech guy. He has lots of patience and is very good at explaining things.
He literally had to walk me through step by step setting up the software, setting up the connection to the car and teaching me how tog the changes he would make and send me via email. The first few days we found out definitely what does not work. Then we moved on to what he could change.
I am very happy with the new tune. It give me power from 20 to 50 and 60 to 80. Much smoother driving in traffic and I have been getting better mileage, (orig was about 18 to 19) part of that due to lift and tires.
Ed is very professional and got on me a couple of times when I did not due things fast enough that could have bricked the car. He also has me doing the test pulls in the same place so that he can really compare Apples with Apples.
If you want to do it, you need the following: 1. Subaru Ascent, 2 Tactrix Openport Cable 2.0, 3. SubieEdit software, 4. Contact Ed. I will be sending Chris back a New Cable which I think he will be renting out so you will not have to buy one.
On Thursday I will be putting my car on the dyno to give Ed more data and will make that available to folks.

I would attached 3 Videos, but being technically inept, I cannot figure out how to attach them.

If you have any questions for me please ask and I will answer to the best of my Non Technical Ability. Any technical questions please ask ED. He knows what we are doing and is very helpful.

To me, "Stage 1" implies HP gains via software/map changes only. Are there HP gains? If not, it would be more prudent to market this as "Stage 0". Again, just my opinion.

Yes. Because of inconsistencies of runs, I have not posted. But I get you. Usually you get tq changes.
