Hi, Gramigno from Milan

    i've one, but still not tested

    i'll try to compare OEM and Puffo by reading the MAP values via OBD
    Bernd, do u think this should work?

    Yes. Comparing MAP values during road driving is the best way IMHO.
    Third gear please, starting from 2,000rpm, WOT until 9,000rpm.
    First and second gear is to fast for accurate datalogging, fourth and fifth gear is to fast for police.

    Happy to read you Pat!

    i think your way to compare should work as well;
    many people tested using different ways,
    from the ECU exit plugged with a PC,
    to the GPS tracking,
    someothers stopwatched and after calculate the missing time as improvement,
    (i still prefere the dynos, but it's just me)

    they ALL had same results:
    it's not that much,
    but at least 5% power encreasement have to come,
    just because like everyone knows,
    maths is not an opinion.

    A guy from here has a test in this days and contacted me to help me to find out,
    but after the results they had testing,
    in this moment french are buyng all my production within 2 months,
    so i was unable to provide a Puffo for testing.

    I hope Pat will find out,
    because his doubt are exactley tghe same i used to have when we started developping it.

    I suggest a test for the guys who have not electronic way to prove it.
    take a piece of unlimited speed motorway,
    strting from zero reach the top spedd ad stopwatch it,
    do the same test several times in teh same conditions and after uninstall the Puffo and try same test with stock intake fitted.

    Let us know what do you discover.

    Bernd, how can i record the MAP values while driving?

    actual i've the OEM ECU, but in the next months (i hope so) i'll have my AEM - then it will be easier to record
    also i can compare the A/F values

    sorry guys, but i've got not much time at the last months for testing but i'll do it

    You can log the MAP data with an OBD scanner. Not with every, but lot of scanners have this function. Even my IPhone does this with the "REV" App.

    I would propose we do the datalogging this weekend. Come on Patrick, take the time for the short testdrive. I think Gramigno deserves some results finally.

    ok, thanks for the link

    now testing with my OBD does'nt make sense, hm?
    i need a co-driver to read and compare the data - who's crazy enough? :] :lol:

    Hi Patrick,

    in the product details of your OBD-scanner i can't find something about logging. Only about realtime reading.

    I've logged my Puffo with a USB OBD-interface for my laptop. The software i use is named moDiag http://www.modiag.de.

    The following picture shows the result:

    blue = MAP
    red = IAT

    atmospheric pressure = 980 mBar (98 kPa)
    air temperature = 10°C
    gear = 4th
    track = autobahn without speedlimit ;)

    Hallo an die Puffo Besitzer,

    würde mir vielleicht einer mal sein Puffo zur Verfügung stellen ??

    Ich bringe meinen Wagen am 27.06.2011 für ca. 1 Woche zur Fa. Wimmer, um ihn dort abstimmen zu lassen.
    Da ich auch eine vorher nachher Messung machen will, könnte man gut den Puffo testen.
    In diesen Fall allerdings, gegen einen K&N Kit II mit Airpanel.

    Gramigno hat leider keinen mehr auf Vorrat, sonst hätte ich mir sehr wahrscheinlich einen gekauft. Nur wenn ich die Abstimmung gemacht habe, ist es zu spät, weil ich ja dann eine neue machen müßte..

    Hi,
    da mein Puffo noch jungfräulich bei mir zu hause liegt, würde ich ihn Dir und somit der allgemeinen Neugiers-Befriedigung für die Tests zur Verfügung stellen können.
    PM mich einfach mal.

    Gruß
    Maddy


    Thank you Madde,
    i still find easyer to read in english,
    but i appreciate your friendship.

    i will wait with my Puffo-Testdrive until i've installed the J's header :twisted:
    it's on the way from califonia to me :]
    hoping to get it next week

    My Puffo is on its way to Jimmy...


    I forgot maybe to say how i did this results,
    it have to be dynoed with closed bonnet and hight speed air,
    if it's done with open bonnet i don't know how much, but it have to rise because with open bonnet you will have more air then in the real world.
