    Chips for Mi16 motor

    Guys
    I have spent a bit of time searching the net for cost effective computer chip upgrades for an 89 405 Mi16 1.9 motor. I have also talked to other Pug owners and tuning shops over here.
    I was hopeful that Chip Torque in Brisbane would have a prepared chip for the Mi16 but it was not to be.
    Please can I ask which chips have been used by Froggers in OZ, and what is their view OF THEIR WORTH IN PERFORMANCE IMPROVEMENT.
    A very reputable tuning shop in Auckland has told me that the UK Superchip is the only one worth considering. Maybe but its bloody expensive!

    if anything, go for a unichip or something that's programmed specifically for your car.

    I agree with Andreas. I'm not a big fan of chips. I fail to see how a "generic" setup can improve things over the factory settings without taking into account the specific conditions of your engine.

    An interceptor computer such as a Unichip is a cost-effective tool for any car, remembering that it does have its limitations. The main being that it can only alter settings within the factory ranges set into the OEM computer.

    I will be using an EMS fully programmable computer on my 205GTI once the mods begin.

    More to this, are the stock ECU's in the S16 and S2 Mi16 programable in any way?

    XQ has said his was tunned for 98RON however my mechanic said there are no parapeters which can be altered

    ahaha Andreas i think youve been reading the MCCR forums too much and have adopted that quote. lol

    Anyways yeah dont get a chip they are bullsh1t ripoff get a unichip that is dyno tuned to suit your car. When u think about it the chips cost like $1000+ wheras a Unichip is a little more or a full Standalone computer (ie Microtech) is around $1500 fully dyno tuned and installed.

    Anyways a Piggy back computer or full standalone is alot better value and beneficial than a Chip.

    Depends what model it is and what changes you've made. For a STANDARD engine the following applies:

    XU9J4 - the Powerchip adds significant low-mid range torque

    XU9J4Z - both the Powerchip and Superchip are useless, as the std. mapping is 99% right.

    A fellow Mi16 owner in NZ, donh@yhi.co.nz, recently had his XU9J4 chip remapped over the phone, at the dyno place. Don't ask me how, but they sent the std. map with dyno results up the phone line to a programmer, and got back a modified progam for the chip, which was reburnt at the dyno place. All for an unbelievable NZ$195. I suggest you email Don and find out more. I've been using Haltech ECU's for approx. 12 years now, but at that price and convenience, why would you bother?

    does it show?

    i've had a chip before and while playing with it too much it was damaged, i didn't bother replacing it as at the time they were $600, i hear they're alot more thesedays.
    i'd only paid $100 for it anyway.
    the money is better spent on tyres/brakes/suspension.
    or wait to see Cal's results with a unichip, advanced timing, exhaust and CAI.

    I agree with the sentiment here. I'm not a strong believer in a simple chip upgrade as in the most part the factory chips are pretty good. There might be exceptions to this but I haven't yet seen any, and tried quite a few in a Suzuki Swift GTi - past life wink

    I think the fully programmable computers like Haltech, Motec, Autronics etc are worth the extra $ if you are going to modify the car and want good power, torque and reliability. In my experience, the Unichip only goes part way towards this by intercepting key parameters and 'adjusting' (read fooling) certain parameters accordingly.

    Give me a month and I will give you an answer on whether the Unichip works or not. The cold airbox goes in Saturday. I should have the 4 degree advanced cam wheel from Owen in a week or so. Including the 2 1/4 exhaust I already have, this will be the end of the mods, so then I will get the Unichip setup for my car to run 98RON.

    Phasis:

    XQ has said his was tunned for 98RON however my mechanic said there are no parapeters which can be altered
    Yes, there are no major things to be altered, but i had the Timming advanced, which thus suits the 98ron fuel better, I had (notice past tence) a Dyno sheet to show a small increase a top, but a nice fat increase mid-to-upper rev range, nothing crazy but worth it.
    The OEM ECU tuning is very limmited but can make a difference.
    Im still tossing (thought i grew out of that,lol) what further ill do, maybe a full Aftermarket unit, or spend the money on a LSD for the g,box.
    As for those mail-order chips, i hope they come in a flavour you like.

    So Cal,

    Have you got some feedback for us regarding your performance upgrades (cold air box, cam wheel, exhaust and in particular.... the Unichip).

    No I don't sorry guys. Due to a couple of different factors, I probably won't for some time yet. The cold air box STILL isn't finished. This must go on next followed by the cam wheel, then the Unichip. So at the moment they are keeping each other company in the garage along with other bits.

    Cheers,

    Cal (or perhaps Peter T?) I have adjustable cam verniers on my Mi16 and we wanted to adjust the cam timing.

    Pardon the mechanical ignorance but is the 4 degrees advance you suggest applied to inlet or exhaust cam timing?

    Steve, It is on the inlet cam. I am now unsure of whether 3 or 4 degrees is ideal. I just picked up a Euro camwheel from Owen. Mine will be fixed, not adjustable. Peter T will know more on the subject.

    Don't bother with chipping an Mi16. Send me $1000 and I will send you a 'magic happens' sticker. Fitment is free.

    I don't think anybody will disagree with that. We are talking about a Unichip though. Not a factory replacement chip.

    Hi Cal
    Re the Unichip for Mi16, who is the OZ agent(an email address would be good), is it programmable and how much?
    Does it 'plug into the Bosch ECU', if one removes the standard chip?
    And how is the cold air box coming along?

    Cheers

    Hi Don,

    Here is a link to the Aussie distributor: <a href="http://www.airpowersystems.com.au/unichip/unichip.htm" target="_blank">http://www.airpowersystems.com.au/unichip/unichip.htm</a> The chip is about $1200 fitted. You would have to buy the chip and then have a dyno tuner in NZ set it up. The chip should be about $900 and $300 to fit and tune on the dyno. It is a piggy back ECU. It does not replace the existing ECU. It allows for a fair degree of adjustment. Not as much as a full aftermarket ECU though. God for a few mods but not well suited to say a 200hp+ Mi16 motor. People I have spoken to who use them, swear by them.

    The airbox is STILL not finished. To be honest, I have been more interested in the Toyota I bought for track use. The mods on the Pug will have to wait until I come back from O/S in August. I simply don't have the money to get both cars setup for the track at the moment.

    How have you been going in events?

    Cheers,

    Cal.
