    Aslo got these..
    OBD Fusion App (IOS) 9.99
    Wifi Scanner - https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 17.99


    The app supposedly does these things - among many others:
    - Performance Calcluations for 1/4 mile, 0-60
    - Display HP and Tq
    - Display Boost Pressure in "real time"
    - Display Calculated Air-to-Feul ratio

    lots of others too.. Seemed waaaaaay beyond my need so i bought it lol!
    How do you like the OBD scanner? How accurate is the boost , power gauge, was the install plug and play?

    it works on a V simple principal.. it just tells the ecu its seeing less boost that it is....
    no other parameters are effected or adjusted....
    some think this is just fine..... others think not, as many other parameters are not monitored, adjusted & balanced as would be in a "proper" tune.

    my feeling is that the ultimate boost in intake pressure is at a level that a car in good running order thats been well maintained should be able to hold up just fine to this minor modification.

    to me, it is all about realistic expectation.....
    this thing is good for maybe 10% increase at best.....

    if you can get one for < $200, then i fail to see any reason not to if your looking for a small gain in performance....

    for me, its a good little toy till i get my apr stage two.... at which time i will just flip it, (pay it forward, as they say) at a reasonable used price to some one here, hopefully, who will enjoy it as much i do....

    until then, it works just fine....

    give it some time...

    mine seemed to improve with mileage, as if the ecu was re-learning how best to use it....?

    Ok so heres what i got so far..

    The scanner is super easy to use, it literally is just plug it in and connect to its Wifi. The Stock app is GARBAGE.. you need to purchase an app..

    The ODB Fusion App is pretty cool. The performance calculations seem pretty accurate (did a bunch of 0-60 runs). On the other hand, the boost gauge has to be wrong.. I've peaked boost over 30Psi - I'm pretty sure thats bogus so i'm not hanging any hats there. The best part of the app imo is the logs. You can start a log and run through the gears. You'll get a real time graph showing you HP/TQ/boost and in the background a CSV file is capturing second by second data. Using that i was able to see peak HP/TQ numbers (among other useless information) and compare those numbers pre-post Dinan piggyback install. Heres the data in a nutshell:

    Pre Dinan -High water marks:
    226.71 HP - - 259.63 TQ - - 0-60 6.01

    Post Dinan -High water marks:
    252.33 HP - - 287.35 TQ - - 0-60 5.65

    Worth noting, i have no other performance mods...not even an intake.

    The Butt Dyno feels like theres something there but without the logging tool i'd be on the fence with how much performance was actually gained from the Piggyback. Numbers dont lie though.. right??


    So gains were 25.6HP/27.7Tq/0.36s 0-60


    Thoughts??


    PS- the Dinan App's boost gauge was WAYYYY more realistic.. Showing boost in the 8-14lb range with a spike at 19psi.

    Your calculations basically mirror what I estimated from MAF measurements and experience.

    Ok, so as i eluded to a few moments ago...

    (All tables were sorted by Highest to Lowest for Tq)

    Using ODB Fusion (IOS App) i was able to generate some log files. I wont bore everyone with posting results from each.. this one below pretty much sums up my stock runs. Didnt take the car much past 60mph but it was WOT at every possible moment.




    Same App, 2 days after installing the Dinan and did a highway merge up to about 80MPH and the below was the capture.. as you can see.. RIDICULOUS numbers.. i mean straight up crazy..



    So my stock runs turned out stock numbers (as expected) and then my Dinan runs have turned out some pretty insane numbers - numbers that are far beyond my capacity to believe to be true..
    The car does feel a whole lot different, to the tune of 90Ftlb's...Nah..cant see that being the case..

    I guess where i'm going with this is...WTF?!?!?!

    Well we have already established the boost levels are nowhere near realistic as read by the ecu, which may explain why some of users are getting underboost codes from time to time. (I do hope it's not really a leak or worse)

    We need someone to dyno....

    Well a piggyback works by tricking the ecu and one of the values is boost, so...

    How are you doing the hp calculations? If boost is in the calculation then your calculations mean nothing is what I meant.

    ....which would explain why the only reasonable #s i get are when using the dinan app....
    ....with an assumption that the dinan app applies a correction to the data it is accessing from the ecu.... ?

    Just putting this out there. I have a D440-0046 for sale for $150 shipped in the USA. Only used about a month and a half, comes with the original box and some cable ties.

    I got that with the neuspeed one. I think I got the code once with the Dinan. My turbo got replaced under my cpo.
