  1. bump?.?

    I was playing around and noticed that if I switch back and forth between Fahrenheit and Celsius on Rom raider at the same time with the car warmed up it reports 205f and 100c oil temps. That doesn't match my memory of middle school math. Wouldn't 100c = 212f? I know its not that much but still not extremely accurate. Fyi after spirited driving and extended idling I never went higher than 100c and 205f.

  2. Hey Steven, yes I can confirm the filter I recently switched to increases airflow over the Takeda supplied dry cone filter. I tried a Donaldson PowerCore filtering element from Volant.

     

    Up top and @ WOT, it outflows the Takeda element by 200-300cfms (25-37g/sec). Torque logs and live data tell me that the MAF sensor is supposedly seeing as much as 240-250g/sec now vs 220-230g/sec I've seen before.

     

    However this filter doesn't work well in all applications and intake designs.

    It can cause issues for both FI and NA (especially FI) applications when the MAF housing is located too close to the inlet. Under and over reporting air as well as outflowing the stock MAF 300g/sec limit.

    This can be scaled and interpolated on older Subarus like ours, but not the 2015+ cars yet.

     

    I believe Fredrik is running a longer (7"?) AEM Dryflow with a custom pipe in place of the airbox while DJMajickMan has a monster filter (9"+) sitting in his passenger wheel well, getting cold air from the lower grill to WRX bumper vent blow-by.

    So I need to get tuned for your filter?

  3. I will have to check this for you, maybe on the dyno because torque seems to only give me g/sec or cfm. I've switched back from the cfm to g/sec recently and similarly to stevenc1703, I see 230g/sec, 240g/sec. I believe I've seen as high as 250g/sec.

     

    With the same filter elemenet on a 2015 WRX, and a target boost of 19psi - we pegged the 2015 WRX MAF @ 300g/sec @ 4K RPM and above.

    Switched back to a standard cone filter and see about 200-210g/sec (@16-18psi, 4.9-5K RPM, WoT, 50mph). I believe the highest logged on the dyno was 250-260g/sec.

    What air filter are you using? I'm still using the takada filter but I know you guys have another one on there, I wonder if that would increase air flow.

  4. What actual MAF voltage do you generate?

    Most VF52 setups only get into the 320's. Yet to see a 3.6 crack 240g/sec without boost since the stock injectors only have enough fuel for 250 or so :)

     

    Looking at my logs the highest I've hit is 231 @ 1.6v

     

     

    I been doing TCU tunes longer than anyone ;) Check previous post about the Outback 3.6 with low boost turbo kit. Even perfected the 2.5i CVT Tuning

     

    No doubt, I was just saying that no 3.6r on this forum has had theirs tuned yet, not that they won't all be soon with the Race Rom coming out. :D

  5. Nice setup, I wonder if those are the direct sensor outputs.

    For example, two AFRs would lead me to believe one is 'commanded' (what the ECU/tune requests and the other 'measured' (as approximated from the wideband and MAF/IAT/MAP readings) as a result of the instantaneous fuel trim changes. Good to see g/sec and C for a change!

     

    Sounds a bit strange, the idler pulley you pointed out (and the belt tensioner pulley) both have bearings which allows some play and wobble. You can replace the pulleys or just the bearings... plus while @ it, grab a Gatorback serpentine/accessory belt! Best $$$ I've spent on the car short of the RSB.

    I think one is driver side wideband sensor and the other is passenger wideband sensor but I might be wrong. There are a bunch of different af readings from different parts of the car. Here are just a few of the readings you can monitor.

  6. I'm working on a new setup, can't wait to finish it and show everyone.

    It's not completely done, I'm waiting on the car kit for power and a better dash mount and I need to run the wires a little cleaner I might even put it in a different place but I think it will work. http://tapatalk.imageshack.com/v2/14/08/22/2e9f26365d92d12996a8a9e3afa26d88.jpghttp://tapatalk.imageshack.com/v2/14/08/22/bab379d8d4a09503946ba16355e24a03.jpghttp://tapatalk.imageshack.com/v2/14/08/22/5fa4c3294e69f375a1bfb4ca666049db.jpg

  7. So far, just the intake. If I go the OpenSource route, I'm probably going to ECS since they've already done Giovanni's and they're only about 90 minutes from me.

    XRT was able to do a indirect trans tune, I haven't seen anyone else on here have that done yet. Just something to consider. If you get a borla exhaust I could send you my tune to give you an idea how it runs. There is one for sale in the for sale threads.

  8. Yeah, I purchased the Tactrix cable for the same reason; to pull the 2012 ROM image and get it defined. I even pulled some log files but I never got a tune. I still have the cable sitting in the closet.

    XRT did a great job on mine. Now that he did mine he has a good starting point for other 3.6rs. What mods have you done?

  9. You know, I checked your build thread right before I posted that just to check to see if you had tuned your car. You need to update the 1st post of your build thread. :redface:

     

    So, if you already have the Tactrix cable, why would you need the vagcom one?

    Yea it's a little out dated, I just finished the tune. Im not curious for myself as much as others. If I knew before I bought the tactrix cable that I could have bought a $8 cable that did the same thing I would have saved myself $170, I figure this is all part of paving the way for others. All of us experiment so that other people don't have to, that's the beauty of these forums.

  10. Like I said, I have no clue.

     

    I do have the '11 ROM image for the EcuFlash software btw, what I don't have is the defintion file. I have nothing on the '11 for the RomRaider software and I haven't seen anything for it on the RR forum either, so for now your only choice for tuning might be EcuTek.

    I have a 2011 3.6r and I am tuned using ecuflash and Rom raider to log using a tactrix cable, im just curious if there is a cheaper way that might help other people in the future.

  11. No, you got it stevenc1703. With Ecutek you have a few options:

     

    a. local tuner tune - no hardware needed, pay for license+tune/dyno time only (use tuners Ecutek suite and cable, dyno tune from scratch or using a base tune with same/similar mods as... base)

    b. e-tune - hardware optional, pay for license + e-tunes, potentially cables unless you can use and send back (buy or 'borrow' the ecutek cables to dump the stock rom, flash/re-flash e-tune revisions)

    c. tuning suite kit - hardware and software, pay for license + cables, Ecutek software, RaceROM, tuning suite (grants access to DB of many base maps across a few makes, RaceRom where applicable, allows for customer tunes)

     

    Personally I've gone with b, both with Visconti and now AMR. I don't have any hardware, cable or kits and never had to pay for them. I only paid for the license and the dyno tune sessions. Subsequent re-tunes are usually much cheaper (typically within the price range of a dyno pull session).

     

    The screenshots above are from Torque Pro, just reading the generic (non-Subaru ISO) OBD II PIDs. I'm logging this data using OBDLink MX and phone.

     

    I've read that a vagcom cable will work with romraider. You could try that if you wanted to know which readings are correct with torque.

     

    How much is a ecutek cable?

  12. Nice! My MAF readings off of Torque (converted to cfm) show a supposed peak @ ~1700cfm (802g/sec). WoT/100% load, 55-75mph.

     

    Typically in the 400-800-1000 cfm ranges (189-378-472g/sec).

     

    MAF (and a few other related sensor read-outs) have been re-scaled with the most recent Ecutek tune, post intake install. Could this be skewing the readings?

     

    If your turbo'ed EZ36D is pumping 420g/sec, then there is no way my NA motor is reaching 472g/sec, let alone 802g/sec.

    I think I misunderstand the ecutek tune, do you actually get physical hardware that connects to your car to keep? I thought it was a tune using the module but you didn't keep it. Does the module give you live readings like the cobb access port? If you can log using the ecutek you should connect your laptop and your phone via a obd splitter and compare results to see what is accurate and what is not to narrow down a good list for other torque users.

  13. I've been told that maf readings Will be very close to actual hp numbers. Rom raider seems to be very accurate in readings, torque not so much. Even the greddy informeter I just got has some readings that aren't accurate. You could get a cheap vagcom cable on eBay and log with a laptop and romraider. I could send you a log to compare with and see which torque readings are probably accurate and which are not if your interested.
