    XE5 (1199) - (46BHP Increase) This is the maximum this engine can push out with standard AFM and without going to throttle bodies. Giving the camshaft a different lift duration to previous kits, modifying the cylinder head for max airflow and with the insertion of new pistons we have achieved 200PS (196BHP) from this setup. Software is again changed but Fuel pressuer is remained at 3.5 Bar. RPM Level 7500rpm
    WTF!!! now i'm raged

    if someone representing v-max wants to come on here and explain to me how they squeeze enough air and enough fuel through a single plenum and single throttle body to reach 185bhp where 4 bodies and mapable engine management dares to tread, i will happily eat my hat.

    how the hell do they stop the AFM spazzing out with flowed head, mad cams and high comp pistons.

    heres something to think about.

    south africant kadett-e superboss, XE + shrick cams + brospeed exhaust + new software = factory quoted output of 170bhp

    i believe the shricks are 268 duration, 10mm lift, which is your textbook fast road cam, basically the best you can have without needing modified pistons and retaining some margin for error needed on mass produced car.

    where do v-max get the extra 15 ?

    And they're happy to have a standard 20XE revving to 7.5K rpm?

    Would standard internals take that?

    you'd think after 15 years of claims like this, someone, somewhere, could've substantiated this independently.

    err, that'd be no then - and companies are still taking people for mugs.

    The only way that V-Max are gonna prove this is to have each setup independently verified at a good rolling road!
    Sir, please step away from the car

    I do know that a courtenay chip gave a difference of 8BHP at the wheels over a std ecu map.

    tested on the same rolling road, same day,same car.

    Thought that I might try and state a few things:
    The figures quoted have been used and proven.
    Using optimax fuel, increased fuel pressure and different camshafts, these gains are possible.

    you go on to say about an MBE management system... what is this...an ECU...what is the motronic...yep, an ECU

    This chip is NOT! a superchip! Superchips do not have the knowledge to map a motronic ECU as they do not have values for the map and what they change is a bit hit/miss. V-max do have the map so it is every bit as good as the MBE and if not, better...

    Regards

    Gavin

    PS - RPM range is increased to 7500K but it doesn't mean you have to take it there...

    hmm. superchips do have all the cars OE maps and will be adding 10% midrange, 5% top end and -5% motorway cruising as well as adding a degree to the advance WOT for most applications. not ideal as you agree, but what do Vmax do thats so different? and how do they know this?
    any cam over 272 iirc degrees will cause a flatspot in airflow in the AMM area which will errr **** the motronic up basically. its been tried and binned many a time as moving the AMM gave bad throttle response.
    why increase the limit to 7500 to not take it there safely?
    not knocking, just saying. do you sell the cams separately?

    For once im staying out of this! As i said it will all come out in the next few months as people have this kit Rolling roaded. The XE potentially will be no where near as problematic as the LET is though

    Where? Graphs? would like to see the RR graphs..

    Using optimax fuel, increased fuel pressure and different camshafts, these gains are possible.


    ??? They certainly aren't on the standard induction. (1) The AFM throws a wobbly with anything like better cams. and (2) the AFM also provides a nice air-flow restriction


    you go on to say about an MBE management system... what is this...an ECU...what is the motronic...yep, an ECU

    This chip is NOT! a superchip! Superchips do not have the knowledge to map a motronic ECU as they do not have values for the map and what they change is a bit hit/miss. V-max do have the map so it is every bit as good as the MBE and if not, better...


    Superchip, like everybody else have the addresses and information to decode the maps in the Bosch series of ECUs, for $1000 I could have the program to alter the bosch motronic maps too. So you map to every engine then rather than just programming a pre-worked 'generic' map into each engine? I think not!!


    PS - RPM range is increased to 7500K but it doesn't mean you have to take it there...
    nice quote, so it's a users risk only thing? Do people have a leg to stand on when the rod exits their block because you've moved their rev limit out of the safe operating area?

    IMO that was a poorly put together post, sorry.

    got to agree with you brian, dont think you can compare a generic chip to a fully mapped stand alone management system really

    well, you could if you compared it to a basemap....some on here know how far out mine was!

    lmao

    nice, bet its a bit faster than a 'superchip equipped' astra now though eh?

    You know, this got me thinking, why everyone suddenly doubts the N/A gear, yet the phase kits bob along fairly unnoticed.

    The N/A tuners seem to care about fueling and ignition, you want to know what the ignition advance is, you want to see what the injector duration is, etc, etc.

    Yet the turbo peeps are happy with.. yeah, it's running xxpsi of boost, and it's overfueling slightly because the plugs are a bit black.

    In my usual sarcastic way I exaggerate the turbo scenario, but in essence it's true. So long as the next upgrade has a higher boost setting, everyone is happy, the ECU must be fueling correctly, and using the correct ignition advance for your engine, I mean it's all one power kit... strange how trends set in...
