hi all, i'll be gettin a full system for my 94 impreza wrx import. wots this re-mappin ive heard about? is it just for the ecu to get the best out of my car? wud i need to get it done?

Alan Jeffery

It's a good plan to have your car checked over if you modify any part of it.
You would need to fit an ECU such as an Apexi or Simtek stand alone, or an add on such as an ESL device. Assuming your car is standard, you can't tune it at all without one of the above or similar.
The object is to be able to correct any problems, and tune the engine for best performance.
Price roughly £250 to £1000.

Perhaps Alan can clarify what he is recommending at £250, plug in chip perhaps ?
I would budget on at least twice that for the most cost effective mapping option, for a mildly tuned car I'd recommend the ESL live custom mapping of your existing ECU.

depending on what mods you already have, you could try here

I'm not recommending anything at £250!
I keep seeing guys on here telling us they can get it "done" for that.
Best of luck to them...
If I was touting for business, and I wasn't, I'd recommend he comes all the way down here for a Simtek! As he comes from somewhere very North indeed, I'm sure you would be number one choice in any event Andy.
As long as he does something with it?

Probably worth doing a few more mods like injectors,manifold,intercooler before a remap just to maximise the gain of the £600 ish that the remap will cost.

Alan Jeffery

The initial cost is the hard part! We've often fitted Simteks to otherwise pretty standard cars. The gains are immediate, and at least you know it's set up correctly. A couple of hundredish is enough for a later stage remap if you've moved on spec wise.

bloody hell it shows how bad this place has got when 2 regarded tuners come on here and bicker with each other at every opportunity

it's as bad as ps lewis digging at everyone who asks about oil

Alan Jeffery

Andy must have had a bad day.
It's like Afghanistan here sometimes, if you stick your neck over the parapet, you got to watch out for bullets!

I simply didn't want anyone getting the idea that the ESL custom mapping was £250 but Alan clarified that

daves2rs

I have a midly tuned 94WRX Import which Andy remapped with the ESL option and it completly transformed the car. If you do decide to go with a mid range power option then I could recommend the ESL.

Andy, fixed the earthing problem, was moisture in a sensor

lol, group hug

it's just that it's like a bloody playground on here recently the other day Zen posted a pretty catty comment (before it was edited) which was a red rag moment for Mocom, to the extent Paul spent virtually a whole page back tracking.

don't want to sound like teacher here, it just seems a bit daft for grown men to bitch like they are.

if someone's talking 5hite then fair play they deserve to be put in their place, but picking holes in comments or advice to make someone look a **** is OTT in my opinion. do your talking on the track/strip

or have i missed the point and there's a sweepstake for who can be the bigest bitch on scoobynet

Dear tuners/specialists

Apologies for the hijack, but any answers to my questions will help the OP too, I should think...

My '93 WRX is running its std TD05 16G; Green panel filter; 3-inch bore centre pipe/backbox and Scott T's PP stage 1 generically mapped ScoobyECU (this is the same as ESL's stage 1 non-mappable chip, non?). I'm happy so far...

Anyway, at what point in the quest for further engine mods/breathing, would it be prudent to upgrade to the ESL stage 2/3 fully mappable ESL Live map, or indeed, Simtek? Presumably, it's not really required at the mo, what with my very modest mods (aside from having a very accurate map, for peace of mind)?

Presumably, to make it cost effective, at the very least I'd need to add a decat-/sports cat-downpipe plus, say, a FMIC, yes? Please advise...

joz8968

bttt... anyone?

Andy Stevens

You'll feel the benefit of a remap on a completely stock car. A nice tune on a 93WRX is a FMIC, later MAP, walboro and 440s on top of the exhaust and filter you already have. That was the spec of my sprint car and that didnt hang about. Did do a gearbox a season though.

Thank you - appreciate your answer.

Yeah, the mods you mention are the sort of 'stage 1' things I was thinking. BTW what do you mean by 'later MAP'? I thought MAP was an acronym for Manifold Absolute Pressure - and in this context, doesn't make sense(?).

Do you mean later MAF? If so, why would that be?... They're supposed to be a lot less robust than the 92-96 ones - could you clarify this point please? Thanks.

MAP 'sensor' he means.....

joz8968

iTrader: (13)

Oh right. What's 'wrong' - or what limitations - are there with the early sensors then? Cheers

Andy.F

The 92-96 sensor only reads to 1.2 bar. In order to allow the boost control system to operate properly it is not recommended to set the boost target above 1.0 bar, the problem with higher settings being that the control loop does not see any overboost worth correcting.

Andy

joz8968

iTrader: (13)

Is this the MAP sensor?




Cheers Andy. Will it be working correctly with my ScoobyECU (where max boost is 1.1bar), then?... I'm assuming that although max is 1.1, the 'target boost' is probably set to 1.0bar or less, yes?

no that is idle valve..

map sensor is square and on drivers inner wing / suspension turret

Scott.T@PolarPerformance

LOL...Upgrade for less then £250....where would they be available from ....

Can't be that bad though IIRC one customer with UK Wagon, TMIC and decat running 1.1bar managed 296BHP at rolling road in the West Country.
I'd admit that is very Good for a UK car, but quite happy to quote it .....

Nearly 500 units sold and only 1 return.....you could probably say that they serve a purpose until the customer wants more then 1.1/1.2bar.

joz8968

iTrader: (13)

Was that it?! Just remapped for a decat downpipe and nothing else e.g. no centrepipe, no backbox, no filter - just decatted d/p?! The owner must've been laughing his head off!

Scott.T@PolarPerformance

I take decat to mean a full stainless system.
A bit pointlees to decat the downpipe and leave the rest as standard.
Probably had an induction kit aswell, but thas not gonnta make a lot of difference at this level (other then hotter air and noise)

judging by the email he sent me...yes you could say he was happy. but as mentioned above I was suprised/pleased with these reuslts too for a UK.
Would normally expect around 275-280BHP.

joz8968

iTrader: (13)

Blimey. Even then, at the 'expected' minimum of 275bhp (up from 208 or 215), is mightily impressive stuff... but 296 is just insane, what with those modest supporting mods! No wonder he's happy! Was this achieved using your stage 2/3 live map?...

Scott.T@PolarPerformance

16.11psi mapped postal chip. No not a live map

You can get 260HP out of a UK running 14psi (0.95bar), OE Downpipe, decat centre and ITG Panel Filter...well my old MY94 UK did back in 2002 when I started playing.......

joz8968

iTrader: (13)

Those figures are even more impressive, bearing in mind just the generic map!

I've got your non-mappable chip too (thanks by the way )... As a rough estimate, what do you reckon my '93 WRX saloon is putting out with its Green panel and 3-inch bore system - std d/p only though (it has a new engine with an alleged 23k miles on it)?...

joz8968

iTrader: (13)

Is the smaller highlighted area the MAP sensor, then? It's the only (vaguely) square-shaped thing that I can see that's on the driver's turret?!

Jolly Green Monster

iTrader: (4)

yes
