  2. Thanks for the support guys.

    To be fair, I have already answered this question in an email and actually recommended Dastek.

    For a stage 1 tune on a standard-ish car the Unichip offers better value for money than I can with the Apexi.

    Where the Apexi Power FC scores is if you are embarking on a tuning programme over an extended period and may require a number of mapping sessions as you progress. Also the resale value may be something to consider.

    Gerry at Dastek knows his stuff and it is a first class set up they have there. Just not sure if Gerry still does much of the regular tuning work however ? The kit is only as good as the operator so make sure you ask for Gerry !!

    cheers

  3. It depends upon what you get the enjoyment from, building them or driving them ?

    I guess it's like saying to the guy who climbs Everest " You have gone to all that effort, what the hell you coming back down for, why don't you stay there " [:D]

  4. Sorry mate but this is rubbish! it will need a remap. We have 100ron V-Power over here and the standard UK tek2 ecu could not compensate for the extra ron! under hard acceleration your car will boost to something like 1.2bar then drop to around 0.4 bar then it will boost again to 1.2 then drop to 0.4. How do I know this I hear you ask? well that is because this is what happened to mine so I spoke to Bob Rawle and he confirmed that the ECU could not handle the extra ron.

     

     

    That's rubbish ! Extra ron, over and above what the car was mapped for will have no effect on the boost control. If this was the case then every UK car designed to run 95 ron would have issues with 98 ron optimax or 99 ron tesco fuel. This clearly is not the case.

    Andy

  5. "Most" standardish UK cars will cope with a 50 shot if you use Optimax and octane booster. JDM cars and N20 do not mix unless they are remapped to suit.

    Running N2O will increase the burn speed and eat into your OE safety margin. With JDM cars, you are already well into the safety margin just by using UK fuel.

  6.  What's your experience in terms of degrees more advance with running octane booster? (typical figures)

     

     

     

    It can vary Alan but approx 3-4 degrees with 3ml/ltr NF or 10% Methanol. 95 octane usually requires 5-6 degrees less than Optimax and really makes a high boost engine feel flat, not so much effect on a std boost car.

    I do a fair bit mapping in Southern Ireland and they only have 95 there, it's depressing work !

  7. Its not all doom and gloom and potentially has as i mentioned a few weeks ago been loaded up with nasty texaco fuel disguised as optimax in Keele Services which has caused the ECU to retard/wind back 3-4 degrees having picked up danger/det. A clever bit of technology no doubt. Can this happen so easily??

     

    This is the ECU doing its business as designed. it will retard timing if it hears the onset of knock, power will reduce as a result. This is usually fuel related, other issues that can cause it are over temperature (unlikely this time of year) burning oil (not expected on a car so new) running lean due to failing fuel pump (or maf on 99/00 cars)

    There are many more reasons the ECU will retard timing. Sometimes the ECU's can be V E R Y slow to return to normal, a reset being required in some cases.

  8. Anyone suspect the recent quality of our Scottish Optimax ?

    My 03WRX has taken a dislike to it lately. I have a number of maps for the car for 95Octane/ Optimax and Optimax plus booster.

    On my Optimax only map that the car has been running happily on for the past six months, after last fill up it almost immediately switched down on to the low octane maps, suggesting it was not happy with the fuel ?

    On further investigation the ignition timing had also retarded some 4 degrees due to knock detection.

    I also had a customers car in recently that was only happy to run what I would call 95 octane timing advance.

    Just wondering if this is just a localised batch (wrongly filled storage tank?) or if it is more widespread ?

    I know some of the tuners down south had a few cars let go shortly after the Hemel Optimax shortage, they blamed that on the new batch of  fuel.  I'd be surprised if that would affect us up here as we are supplied from Grangemouth I believe ?

  9. "Does BIG BHP mean fast road car"

    Depends on the road really !

    In 95% of situations/roads I prefer my mid 300bhp WRX over the 800/900 ? or thereabouts Sti.

    Most that go for the big numbers will eventually reflect and concede that the greatest driving pleasure came from a

    much lower bhp version.

  10. << On the graph the torque peaks arround 3600 revs.

    Can anyone explain why it then drops at 4000 to 290lbft, then rises againg at 4500 to arround 295 lbft. After this it falls steadily. >>

    Thats usually due to a boost spike on the rollers. This doesn't happen the same on the road as when the power rises the car starts to accelerate harder, on the rollers it is held back regardles of power, hence the boost (read torque) spike.

    Andy

  11. Intercooler and turbo would be the next move.

    The original TD04 is pretty much maxed out at this level but the upside is that it is on full boost by circa 2500rpm which makes for a very wide and useable powerband face-icon-small-smile.gif

    I'm currently running my own WRX 03 on a TD05-18G at circa 375bhp but to be honest, once the testing article is completed for scoobymag, I'll be returning to the TD04 hybrid with 320/320 and full boost from 2600rpm
