Can someone tell me if my ECU can be mapped? My car is a S Plate 1999 MY00 Uk Wagon.

Cheers.

S reg 1999 will defo be a MY99 (although an S reg could also be pre 1st Sep 98, in which case you'd be 'unlucky' - odds wise - to have the non-mappable MY98 car ). See below:-

On your inlet manifold you'll see the coilpack - is it offset, from centre, to the passenger side a bit (MY99/00 cars )... Or is it pretty much in the centre of the IM (MY97/98 cars )?

But I'm guessing the car in question is your avatar? If so - and if that "phase 2" bumper is factory fitted - then yes, you have the MY99/00.

As said, the MY99/00 car IS mappable via ECUtek software. Around £600-650 for the 1st map (includes having to purchase rights to a licence that allows the mapper to legally map the thing).

Subsequent FULL remaps would be in the region of £300-£350 though (licence already paid for)... And minor map tweaks a lot less I guess(?)

The std ECU can be tek'd or open source mapped.

Cheers for the help chaps.

The car was registered on the 29/01/99 and the code is GF8GK8D. MY99 or MY00? I'll let you decided as there are different opinions on the date code.

LOL, not this again!

It was thought that for JDM cars G is MY00... but it would seem with UK cars G is MY99 (H is MY00). There was a massive thread trying to get to the bottom of this.

But no matter, yours should defo be a MY99 i.e. from Sep 98 to Aug 99 (your reg'd date is within that bracket).

But even if it was a MY00 it dont matter, as BOTH MY99 and MY00 ECU's are mappable by the same software options i.e ECUtek and Opensource... so you're good to go.

Thanks for your help mate. I know the year code has been mentioned countless times.

My next question is. Would I need to re-map with a K+N 57i, cat back exhaust and V5 dump valve?

seddomyster

iTrader: (9)

yes mate as the k an n will cause a weak mixture in fuel an therefore cause your knock sensor to try an compensate. dont think dump valve alters much but cat back an k an n yes. injectors are ok an the power u will get u wont need an upgraded tmic. get a few horses though but dunno if worth inesting in a walbro fuel pump

Cheers mate. It's does smell a bit lean @ idle and pop's a bit on over run. Would it be an idea to go back to standard air box?

seddomyster

iTrader: (9)

yea mate be best. i done the same thing an drove for thou of miles an was fine but i dont think it will help for future. they say induction kit are only good for 300+ bhp. get an uprated panel filter as this will be better for your remap

Sy5

iTrader: (6)

Are MY00 and MY99 air boxes the same?

seddomyster

iTrader: (9)

i think so mate yea. dont u have an airbox?. if u get a remap with induction kit it will be fine once mapped. if it months before u decide to get map then best going back standard until then

I got the car with the K+N already on along with the exhaust. I don't have a standard box but will get one. It will be a while before I get it mapped due to fund's. Is it possible to get the UK car mapped to JDM spec without changing anything?

Your car's small TD04L turbo is the limiting factor as far as bhp goes. They're normally good for around 280bhp

Your mapper may be able to squeeze more from it as your MY has 440cc injectors (good for <350bhp) and a TMIC capable of handling over 300bhp...

So yes, you'll achieve at least the same output as the JDM MY97-00 276bhp STi's (and WRX saloons).

You don't need a K&N (or other) cone IK for this level. Best retaining the OEM paper element, or of course an uprated panel such as A'PEXi, K&N, Green, etc.

A panel filter in the OEM airbox is advantageous to the MY99/00's less-than-robust MAFs where, otherwise, an IK cone can put too much strain on it via vibration, and any cone filter oil can knacker the MAF's hotfilm element.

Thats the answer I wanted. Cheers.

If I were to get this sort of BHP would the turbo be more at risk of failure? Would I NEED a TD05 or similar?

TD04L will be worked at it's max efficiency etc. at 280bhp+ i.e. blowing as hard as it can. But, that said, the TD range of turbos are notoriously tough little critters and last for ages.

As an example, my TD05H is exactly 16 years old... to the day!!! LOL (assuming it's still original of course), and there's absolutely no smoking, whining, etc. and pulls like a train (car... so far ... mapped at 1.3bar to 282bhp by ZEN). Indeed, ambient conditons were good enough today for it to peak to 1.37bar lol.

plus the td04 has minimal lag so thats a bonus for u

Indeed seddo - I meant to add that too.

Compensates a little for the UK's longer gearing
