just looking into this.

Can a 94 classic be re-mapped if not what would be required to do so.

I want to remove the cat and make use of a boost controller and replacement panel filter along with samco inlet etc.

after trolling the forum i have learned that it is unwise to make any real changes to a scoob without mapping for them.

what are my options.

Have a read of these.

On an early classic like your's the decat will be fine.

Imo don't bother with a boost controller go for the remappable daughter board from Enduring Solutions Limited or a full remappable ecu such as the ones listed on Andy Forrests website.

another website of a respected mapper www.jollygreenmonster.co.uk

I'm assuming then that ecu replacement is my only option, guess i'd better start saving. gonna need bigger stoppers as well me thinks.

great info tho btw.

thanks.

Well the daughter board fits into a holder which is then soldered onto the spare row of solder you have on the ecu,the J1 resistor is cut so you keep the standard ecu which you can return to standard by rejoining the resistor.
unless you want anti lag,launch control this would be the option i would go for as it does use the OEM diagnostics.

bigger brakes will require you to get bigger wheels (unlesss you 've changed them from the ones in your profile)

Will the decat not cause boost surge?

and that ecu sound almost too good to be true, thanks.

I've run a decat on my 93wrx for about 4 years i think (does run a bit rich)
I did uprate my ecu to a later wrx ecu as the early ones do seem to have a poor fuelling map on them (i used to get a lot of fuel cut) BEFORE fitting the decat.

Syph

it states that this board can't be re flashed, does this mean if it required another map i would need a new board?

wheels are on my list as well oh an coilies.

my shopping list is getting longer by the miniute.

No the daughterboard is fully remappable (5 point down on the description) so if (or when) you change turbo,intercooler,injectors etc it justs need tweaking.

I would personally leave the coilovers (for the mo) whereas you could spend the money on some slightly thicker ARBs.
You will find the imprezas do understeer like a bugger when pushed hard,with a few suspension tweaks you can get rid of most of it.

Syph

I was thinking colies as this will allow me to go a bit wider on the wheels and the adjustment is there for the future.

hi mate id defo save for a new ecu like i have because once u start modding u just cant stop but id get all ur basic mods on first induction, manifold , down pipe coz standard ecu copes alright with them then get the ecu and u will see more benifit coz once the ecu is in most of them are so fine tuned u cant add any more mods without a remap really but it all depends how deep ur pockets are

There are several options
1. Piggyback electronic boost control device and fuel cut defender (risky because ECU is unaware of them so fuelling and timing will be untouched ) : £350
2. Chip the ECU with either the preferred single chip solution or ScoobyECU or ESL Mk1 Interface, from a reputable supplier. Full OEM ECU boost, fuel and knock control are retained along with OEM diagnostics : £100-£200, price depends on the supplier and how he feels on the day
3. Fit ESL Mk2 Live interface (where No.2 above fits), this will provide the same functionality as No.2 but has the advantage of being live mappable, so can support ever increasing modifications £500-£550 (fully fitted/mapped)
4. Alternative entry level ECU such as Apexi PFC (£600 + mapping)
5. Alternative higher spec ECU such as SIMTEC, GEMS etc...with ALS and Launch Control (£1000-£1500)

Options 3, 4 and 5 come more into their element once injectors require upgrade and boost above 1.2bar is required, 310BHP+

As Scott says, the early map sensor can't take more than 1.2 bar boost, so the later one needs fitting, which will need re-scaling of a mappable ecu.
I've had the ESL live fitted to my RA, with later map sensor, and it's wicked! Im running 1.35 bar, with 440cc injectors(standard are 380).
Im about to fit 550's at the end of the month,with remap, so the mappable ecu is coming into it's own, and will do again in the future in sure!

What sort of power and torque are you getting with that set-up mit?

Syph

Good stuff.

So to break it down.

Arbs, induction, decat, first then worry about mapping later.

I've not had it on a RR, fear of being dissapointed i spose! I'd 'like' to think around 320bhp, but thats just a guess!

Syph

Just following from mit.

When a purchased my car i was told that it is a type 260 wrx so with that in mind what sort of gains should i expect from the basic mods.

I assume it will be between 10-15 bh and torque????

Sounds about right for 1.35bar on TD05 and 440's.
Depends how rich/lean it is at the top end, if it's dropping as far at mid 10's then probably nearer 300BHP (although it will run a touch leaner on the road compared to a RR).
