    What are the benifits of it? do you need a laptop to do it? What are the basics of it verses say cobb AP? Seems like a lot of you guys are going that way, why?

    Thanks in advance for the education.

    If there is a good website I could read up on this on, please post it up.

    because its cheaper, the maps are more refined then cobb maps, more power is being made with them,the maps can be made custom per owners desires, talk to wall of TVs hes the tuning man/god

    Basically the openecu stuff can be best described in laymen's terms as the equivalent of Cobb's Streettuner -- but instead of using the AP to flash the car's ecu, you use your laptop instead. Thus, you aren't bound by somebody else's maps/requirements for you car and can do as you like, unlike the AP.

    Thus, it is mainly targeted towards a more savvy user who is a bit more comfortable/knowledgeable with the entire process of tuning. It certainly isn't for everyone as bad things can happen if you don't know what you are doing.

    Hey walloftvs, poking through some threads it looks like you have messed with some 'stage 1' 06 WRX's. Would you happen to have a hex file of one you have lightly tuned?

    I would love to get together and see a 'rex running some OBD2 monitoring before I buy my cable. I am picking out components for the 7" lilliput touchscreen/carpc install, and would very much like to do OBD monitoring with that as well.

    Yeah, I've been tinkering with my new '06 for a few weeks now.

    And the idea of a having a carputer with an obdII gauge package is something I've wanted for a while now. There are a couple of opensource packages with skins for this that look pretty neat.

    Do you have to have the laptop hooked up all the time? Or just when you want to make changes?

    It's just like the AP -- only hook it up when flashing new maps.

    So how much does it cost? I know some depends on the laptop but what about software and cables. What are the minimum requirements for a laptop?

    my 5 year old laptop does everything fine, I would think minimum requirements being windows xp and a decent battery. $100 or so for the cable and the sofetware is free, as of now anyways.

    If you don't have a laptop I'm sure somebody in the club can hook you up with an off-the-shelf map sometime at Firestone. Those are free to download from openecu.

    You might be charged a beer for the use of the cable, though. :biggrin:

    Don't we all. :laugh:

    I thought about trying this as it has to be the cheapest engine management option out there, but I decided a used Utec would be better for a couple of the options that the ECU can't do.

    for me it is perfect as I dont tinker with much except exhaust stuff... I zapped (with AP) and thats it... so getting rid of my AP was the better option... unlike the AP if you want a valet mode or anti theft you then would have to take you laptop with you after zapping so it wouldnt get stolen instead... ha ha thanks Tom.. only 2 more days.. ha ha

    Yup, I gave Mike my old one that Dana gave to me. It can barely run Enginuity -- I would actually use it only for logging/flashing and would use my desktop to edit maps when I had it.

    You know, I think the only reason he doesn't buy a laptop is because then it would have to be a PC, and he can't stand the thought of spending money on something that isn't a Mac. :roll:

    ok, so I have a cable (got it for my Evo, but Tactrix said it will work on my Sti also) and a laptop (with EcuFlash on it) Im interested in doing some logging to get started) what is the best logging program?

    I use ecuexplorer for logging, but am going to switch over to the Enginuity logger real soon (just got a new beta build today but haven't tried it out yet).

    Ditto. What he said.

    I think enginuity will become an all-in-one seeing as how Calvin posted on tari that he has stopped development of ecuexplorer. :(

    Now go take some logs! :biggrin:

    The only reason I'm not sure I want to go this route is because I want a race gas map, and I don't want to have to lug around a laptop everytime I change fuels. But that might be a small price to pay :)

    Same Nuke as the osecu forums?

    In other notes, I ordered my cable yesterday. We'll see how I do, I'll certainly let ya' guys know. From all that I read, the '06 is certainly quite different then all the other year 'rexs.

    Hopefully all these flashes are being checked with a wbo2 after install. I have seen and heard about some flashed not being right. As in the afr is 13:1. Car runs like a champ, but it is a ticking bomb. Just my .02.

    Take a look at the map before you flash it to your car but the ones I have seen out there are safe if your car is mechanically sound.

    That said, after you get it flashed, your installer should take some logs for you while you drive it around to make sure everything is safe. PM WallofTVs. He does good work, brings his own tools, and is very knowledgeable. He can also tune it for your personal car (rather than just flashingthe map and praying).

    The perfect Christmas present! :biggrin:

    We have a memeber of this group that when we flashed his car his afr was 13:1. Everything looked good, didn't knock, but when you looked at his afr, is was crazy lean. Anyone who is willing to "tune" their car without checking afr out the tailpipe is crazy. And we have people on this site that think running a tbe without em is dangerous..............

    Yup. The table ended up reading 9.1:1 before it was actually coming out 11:1 from the tailpipe..

    I had nuke flash the ecu to "stage 2" yesterday and then do some datalogging.

    I also ordered an innovative wideband so some real tuning can commence

    What kind of car? Stock injectors & airbox?

    A post-MAF leak can cause lean conditions -- and a quick check of the LTFT will usually indicate this. I'm willing to bet that the car in question had a leak. The reflash will reset the ecu, erasing the LTFTs (which were probably like 15%) and then it was immediately out on a WOT run. Since the car didn't learn the correct fuel trims yet, it wouldn't dump in the extra 15% (in this hypothetical example) of fuel to compensate for the leak and thus give you the lean condition.

    Or the car had an intake the the MAF scaling wasn't done right (or at all).

    If the car doesn't look good to begin with, I won't touch it.

    Call me crazy, I guess.

    I thought your car ran great on holiday gas. Isn't that why you keep quoting your hp/tq numbers?

    actually if you did more than post on here how great protunes are and everyone who open tunes basically sucks you would see I qouted my horsepower numbers cause I BUILT MY OWN EXHAUST (except up-pipe) and it put down the SAME numbers that COBB says it should.... not cause of HOLIDAY gas... and I was stoked that my not so pretty as off the shelf exhausts ran what it should at the stage it was.... I mean anyone can buy stuff off the shelf from big name companies and think they built a great car, but actually building your own stuff is different and MORE EXCITING when it does what it should for 1/8 the price others pay to have a generic product.... (thats why I gave Kudos to Fobia even though I also gave him some crap for fun)

    I posted that I NEVER had an ISSUE that I could feel or tell with the GAS... my 'Quality' AP with off the shelf map never showed anything else, cause it DOESNT show that stuff unlike data logs... I changed gas types / companies cause they switched back to 92 in my area and so I decided to run some Shell for a bit to see... it seemed smoother, better gas mileage and a little quieter (which I credit to smoothness)

    besides this thread is about Bills question on open ecu not your idea of being funny or mightier than thou by being smug about my dyno numbers... which i dont claim to be anything special other than what I stated above...

    ps.. just cause you own PRO-tuner software dont make you a PRO tuner.... Just like sitting in your garage dont make you a car!!!

    Excuses, excuses. What do you have running in your room right this minute?

    :biggrin:

    Actually, you'll need Tom's laptop because most of the 02s use serial ports and new laptops are usb only. When are you guys getting one? And when are you flying out?

    I am not knocking open ecu flashes. Actually, I have one on my car right now. What I am knocking, is how many of you are just blindly flashing your cars and not checking afr out the tailpipe.

    which is fine, but my AP map was whacked... I am sure it was doing more damage then Holiday gas was, combining the 2 probably worse... the map I am running now is still safe in the AFR's by the ecu... basically we took the Cobb map, copied it.. fixed the whacked out timing and trimmed a couple of things and thats what we are using till Tom gets his wideband and does a fine tune in spring...

    So how come you are open ecu tuned and NOT pro-tuned through the AP?? Dont you run it? just curious seeing as you have the tuning software for AP's and seem to know a lot about it!!! trying it out to see if it works well??


    ps the being a pro-tuner comment was a generalised comment seeing as many people on various forums have bought the software...!!!
