thinking of fitting a chip to my 95 wrx wagon will it help with power of is this just a load of bull, also there are a few avaliable i'm after a simple one that simply clips on etc and has instant increase is there such a thing?

PolarPerformance although there are a few on ebay.
Chip will be soldered into the spare slot on your ecu a resistor (J1) will be cut and the chip will run the car.
Fuelling mods may be worth doing to get the most out of it.

Personally I wouldnt bother with a chip. All it is is a set map, which generally increases fueling and boost and advances your ignition a little. It will not be specific to your modifications.
If you have a pre 98 Impreza, and a replacment ecu is out of the question, speak with simon (JollyGreenMonster) as he can fit and map a daughter board in your standard ecu.
Post 98 the ecu's can be accessed without the need for a replacment board.

A proper remap, specific to your modifications is the way forward

Fitted one of scott.t.,s to my wrx and it made a huge difference i.m.o.a. little money for large gain on the older classics

JollyGreenMonster.co.uk as said by fishfire very good remapper (did my mates Apexi power fc)

fishfire

More gains would be had with a specific map though

I appeciate that a replacment ecu/reflash/remap is not cheap, but without a shadow of doubt, you will see more from a proffesional remap.

Your right, but to be fair to these 'postal maps' subaru themselves use generics maps across thousands of cars and they are not given any stick for being dangerous or poor from the factory. These postal maps are great value, they use a Z4 base map from what I have read which is the 'best' of all early classsic maps and up the boost, fueling and change the ignition slightly. In my opinion its how they should have come from the factory in the first place.

Essentially these maps will get you about 280bhp with just a decat, a custom live map may get you 290ish with just a decat but not much more.

Exactly my point.... around £70-£100 mark for the chip or upwards of £2--400 pounds for live map. a large leap for a little gain . but as said before the live map would be specific to your car/mods etc. each to their own eh?

All been said above really.
Prodrive and anyone else that provides factory upgrades just provides a generic map.
The postal maps for Pre96 are a great mod for the money as has been quoted many times for numerous years on this forum and 'in some cases'they map the car close to it's best abilities whilst retaining the standard map sensor, intercooler and injectors.

Yes, more could be had from a custom map but it's going to be marginal and will cost £550 using the ESL live OE ECU upgrade and mapping or a fair bit more if an aftermarket ECU is used.

At the end of the day it all depends on your budget and your future requirements.

With regard to the comment "All it is is a set map, which generally increases fueling and boost and advances your ignition a little"

if you believe that, then...well...lets just leave it there.......

Just a quickie Scott is the board you sell the same as the ESL board?

Scott.T@PolarPerformance

The Live OE ECU adaptor 'IS' the ESL board. They supply it to me, I then fit & map.
But it is the new ESL board not to be confused with the old board that has been on sale for the last couple years and is not live mappable i.e it's an emulation of the 27C1028 chip (which I do sell).

More info here : PolarPerformance
Or at the newly revised ESL site here : Enduring Solutions Limited

cheers i did see that ESL had updated their website as i'm interested in the remappable board

Scott.T@PolarPerformance

no problem...

fishfire

I am willing to be educated. So a chip doesnt increase fueling boost and ignition then?

fishfire

to quote:

"The performance maps within this code are then modified. It unlocks greater performance with modifications made to fuel/ignition maps, boost target map, boost control map, boost limit values and speed limit values"

I think thats pretty much what i said in a nutshell. The point I was trying to raise is that while there are gains to be had, these are fixed maps which are not specific to a given cars modifications.
I also agree this is a good modification IF that is as far as you are going to go, but could end up costing more in the long run IF an owner decides that more horses are required and ends up getting a remappable system anyway i.e mappable daughterboard/standalone aftermarket ecu.

"The performance maps within this code are then modified. It unlocks greater performance with modifications made to fuel/ignition maps, boost target map, boost control map, boost limit values and speed limit values"


This is a very general statement.
You stated that they just increase fueling boost and ignition.
Does the above state that it 'increases' fueling boost and ignition ???

I wish it was that simple.......

I also have a 95 wrx wagon, recently fitted a chip from scott at polar performance. Cost me 200 notes or there abouts, easy mod, massive improvement in drivability and response.
