I have a standard '04 WRX with a turbo back (decat) exhaust on it.
Long term I will be getting a front mount IC, uprated filter and DV all which will require a remap.

However I'm considering getting a remap to go with the decat in the next couple of months;

My questions are;

1) Once i've paid for the remap (£500ish i think) would I then have to pay another £500 ish 6 months down the line once the front mount and other bits are installed or is it less to tweek a mapped car?

2) Would i see any gains in power/fuel consumption?

3) Are these gains worth the money?

Cheers

yes you would have to have it remapped again once fmic was on power wise you will see a rise.
i would recommend you getting a walbro fuel pump as well.
depending on what bhp you are searching for you may need modded or bigger injectors, bigger turbo(again depends what you have on there)
and if its not been done already a decat will find you alot more power

 

Not looking for any power figures, i'm not that fussed.

Jst wanted to know if the gains I'd see with the exhaust would be worth the outlay of the remap.

 

If you're not changing the turbo anytime soon, then i would do the exhaust, uprated panel filter, uprated fuel pump and a remap, don't bother with the DV. You should see at least 260 HP with the remap.

 

My advice would be save up and do it all at once that way you are only paying for one mapping session.

A tweak is about £300ish

 

A DV doesn't require a remap (many mappers will suggest you refit the standard one), and neither (if you use a better panel) will an uprated filter. You'll be fitting a cone if you fit an FMIC of course

...fundamentally the wrong ones. Your approach is fairly fundamentally flawed here.

Given that your long-term goals fail to mention an uprated turbo, everything else you are suggesting becomes a mis-step.

The standard blob WRX intercooler copes more than fine with anything the standard TD04 turbo can push through it. Fitting a front mount IC in these circumstances is a backward step under pretty much all usage scenarios given that there's no significant charge temp advantage to be gained, and given the effects on throttle response of the huge increase in induction tract volume.

If you stick with the TMIC (or, upgrade to a better one rather than a front mount), you don't need to fit an induction kit - and can go with an uprate panel filter instead.

If you're sticking with the TMIC, you can stick with the standard dumpvalve, which is perfect as not only do you save on the outlay, you are also using the best available DV for your engine.

The remap will give you gains in both areas - although on a newage the cruise fuel consumption gains are less pronounced than on a classic.

However, all of this will be in spite of your proposed hardware modifications, rather than because of them. You would end up with the same improvements if you just got a remap - and under those circumstances would almost certainly have a better, more responsive, more driveable car.

No. The remap is worthwhile. Fitting the FMIC/DV/cone filter prior to the remap is a total waste of money given a standard turbo - backward step.

You'll cover all the necessary bases there simply by fitting a good panel filter, and could spend the money that would have gone on an FMIC/DV/cone in other areas that will tangibly improve your car.

 

If you read my original post I'm asking what the benefits would be if I get the remap now.

Rather than flaming me for what I'm considering doing in the future.

Could have saved yourself a shed load of writing with four words

 

Buy a uprated panel filter and a fuel pump and then get the remap. If you're not changing the turbo then its all you need to do. Forget the FMIC and DV but if you have a pre turbo cat then get rid of that too.

 

I read your post as it was written and answered it on that basis.

I wasn't flaming you I was advising you - and took the trouble of explaining in detail why your future options didn't represent the best way forward for your car.

If you can't tell the difference between suggestion/advice and "flaming", retiring from the forum at this point is probably the best way to protect your sensibilities.

Trying to take the p*ss out of people with the knowledge and willingness to answer your questions is probably not the most constructive way forward. Advice, you understand, not flaming.

 

Everything Splitpin says imo is 100% correct so if you listened to his advice it would save you money, time and hassle.

 

1) Once you have paid for the licence on the first re-map subsequent ones are cheaper (seem to be about £150 for a tweek)

2) I personally saw gains in power and better fuel consumption.

3) Yes. Car drives so much better after a re-map, well worth the initial pay out and future re-maps to take advantage of any more modifications will be less.

 

A full remap through me is £350 for the initial first custom mapping - changes to the map beyond that tend to be between £100-£150 depending on how many changes.

As has been said though I wouldnt bother with the fmic on the std turbo (or the DV) - if you were wanting a much bigger turbo fitted then a fmic may provide a marginal benefit but the STi tmic would be a better option.

Power - yes
Fuel consumption - yes it will be noticeably more economic.

Even on a std car the gains are worthwhile IMO but on yours that has been decated it is essential as overboost can be dangerous to the engine and at the very least not very smooth to drive.

 

Jeez...........some people! Splitpin has taken the time to give you very good advice that you asked for, yet you seem to think he is flaming you just because he advises that you are taking the wrong route re the FMIC. He is totally correct. Again, Jeez, some people..........

 

1) no you pay more the first time and less then after depending on how much has changed on the car and therefore how long the remap will take

2) yes power, torque and mpg throughout the rev range is mapped properly

3) yes..
