FMIC
I thinking of fitting a FMIC, now im not bothered about geting the most out of it with a remap, only for the aid of helping keep the intake temps down.
Would this b safe to do so without a remap, as i said, im not intrested in doing it 4 more power
I read they are good, as the TMIC stops air flowing in after a certain speed, im thinking with a FMIC this wont b a problem, also they look smart!

Would advise getting a re-map to go with an FMIC.
If your only doing it because it "looks good" then you don't really need one.
Would advise saving money till you can afford re-map and FMIC.
Better to be safe than sorry.

IMHO fitting a front mount is of little deteriment to your engine, it's losing the standard air intake that's worrying, and necessitates a re-map.

My Engineering experience tells me that the extra trunking will/does warm the air on it's long journey. The benefits are tiny. I would suggest that a re-map is not needed either ...... what changes so much as to warrant a re-map?
But, if you think it looks good ........ it's your money.

Its a WRX STI Type-R 1999 Version 5
Standard really, 3" turbo system (Decatted) & Pannel filter.
Not really after acheaving any more power with the FMIC, just want it as a precaution from heat soak.
What problem will it cause if i fit a FMIC with out a remap?

None on it's own, it's changing the intake that will kill it.... IMHO ! But you will achieve more power/torque IF you get it mapped.

It's more of an issue for the new age cars, where FMICs often come with a CAIK You must not run a car with one of these fitted without a remap, as the MAF readings will be wrong, the car will run lean and pop goes your engine. With the classics, kits like the hybrid just require you to get a conventional induction kit e.g. K&N57i
I would also not advocate running an FMIC without a remap, certainly not at full boost anyway! At the very least, the car will not run optimally, at the worst, pop goes your engine again. Really, you need a remap, no point in having these mods if you're not getting the best out of them.
FMIC not really necessary unless you're going over 300bhp. Makes more sense in a classic than the STI8 TMIC upgrade IMHO.

Intresting, so what your saying is, with a classic (Which i have) its ok 2 run a FMIC with out a remap as it has a MAF, but opn the new age its not good as it has a CAIK.
You say its prob ok not on full boost, do you mean not on full standard boost?
The reason i dont want 2 remap is i cant justify £650+ VAT (over £750) for a remap and obviously the price of the FMIC, if its going to be much of an issue i just wont go the FMIC route.
My engine and gearbox rebuilds are going to cost me the best part of 3k, its not a bottomless pit

THe classic can be fitted with a CAIK too, but most just fit a conventional induction kit. I would not advocate running without a remap with a FMIC: at the very best the car won't run optimally, you may experience extra lag etc... At worst you might cause another engine failure.
Harvey, who supplies the Hybrid and knows a thing or two about FMICs says that you should most definitely remap the car for an FMIC.

Fitting an FMIC to a New Age without a remap is suicide (or murder) for your engine.
On a Classic I guess it is more like Russian Roulette.
Look, I want to sell as many FMIC kits as possible but I would not contemplate fitting one on a Classic, never mind a New Age without a remap. The reasonong is simple. Your engine is injesting colder more dense air and has the ability to produce more power. The denser charge needs more fuel and you now have the ability to enter areas of the map contained in the ECU that are outwith the perameters of a map that has evolved round a TMIC.
On a Classic you MIGHT get away with it but as a rebuild is several times the cost of a remap, it is very poor odds.

If a FMIC sole purpose is to lower the Intake Temp. and the standard map takes care of that temp reading why would a re-map be needed??
The standard map deals well enough with a hot day in Africa and the feezing wastes of iceland ...........
It's lost on me!

So, what you are saying is that a different map operates in different climates?
I'm prepared to believe an authoritive answer to that if one appears.
Otherwise, I would suggest that anyone who travels from North of Scotland to the South of France gets a re-map booked straight away ......... which, as we all know, is poppycock!!
The change in charge temperature will not approach that seen on a winters day in Scotland versus a summers day in France/Spain ...... therefore, as far as I can see, the standard map will cope well enough.
Talk of exploding engines is pure madness IMHO.

Can anybody shed some light on this?

Sunnysideup is a twonk. He has been a member for 5 minutes and is disputing the comments of someone who sells FMIC for many years and who would not advise fitting one without the need at least to have the mapping checked.
My own experience was that after a FM was fitted to my car, the mpper was able to dial in 5 degrees more timing advance just because of the FM allowing cooler air into the engine. Ultimately its your decision, listen to a well known member who sells FMIC and has very powerful imprezas himself or a newby.

You need to remember that the IC (TMIC or FMIC) is there to reduce the charger temp (the turbo heats the air as it compresses it) and getting the temp back down helps to make the charge denser (i.e. more O2 molecules in the same volume) which allows the ECU to put in more fuel (if mapped for it) to make more power. FMIC's suffer less from heatsoak, as they are on the front of the car, not above the hot engine and turbo and therefore will cool more effeciently overall.
To the OP, have a chat to Zak at Mocom, he may be able to help you out with a cheaper remap, although at your level, you really don't need a FMIC.
