Hi. Can somebody explain me that please ? A friend of mine is telling me that you can map any car's ECU, I told him that mine (v2 Sti 96 with 6K ECU) can't be mapped but can't really explain him why. I'm at work and don't really have that much time to find some info. All I found is saying that Classics 93-96 can't be mapped but it doesn't say why really.

Thank You

 

They can be mapped with an ESL daughterboard

 

V3/V4 cant be mapped

 

^^^ see below used to be the case but not anymore

 

deffo can be mapped jgm charges £525 fitted and mapped. good value considering a power fc 2nd fetchs £3-450 now. plus the custom map to suit your vehicle.

can you get anti lag on an esl yet?

 

I know they can be mapped with ESL but why can't be mapped as they are, without plugging in anything ?

 

On early cars it's all about access to the ECU, a daughter board gives you access

 

Because the older style Eeprom chips used in the OE ECU doesn't have the facility to be reflashed in situ.

 

He's from one of these people that seems to know everything best :-) What he's saying is, that any ECU can be mapped by itself without any chips or boards.

 

Because they are early 90s technology and dont have the kit to do it in very basic terms.

Simon can anti lag be fitted on esl? or is it just simtek upwards?

 

Simtek or Syvecs..

or old gems, autronic etc..

not on esl no

Simon, how come earlier ecu's COULD be mapped, but those fitted from 97/8 couldn't, then from 99 onwards, they could again?

 

are 97/98's mappable via esl yet? i know its been on the cards a while?

 

Not been on here for a while, spotted this and thought I'd 'Chip' in

In theory any ECU can be mapped.
The ability to re-map again and again and again to end up with a very custom bespoke map is where it gets difficult on earlier ECU.

With modern technology, if the interface to the device/ecu has been cracked giving feedback via OBD or manufacturer bespoke protocol, and the flash mechanism is understood, this allows for easy re-mapping

Earlier technology from the mid 80's to late 90's could in theory be re-mapped by either removing and fitting another chip or bypassing the chip with another (i.e SuperChips, BBR, GGR, Collins Performance, Ahmed Bayhoo for the old Ford RS's etc..etc.... ) But the freedom to make multiple changes is limited and hence the end resulting map is either a 'safe' compromise or 'dangerous', but unlikey to be perfect.

There was a little investment in the mid/late 90's on the Scoob 1994-1996 and 97/98 ECU. But the big companies soon jumped onto ECU/Laptop remapping in the 00's onwards and soon forgot and didn't care too much for the earlier technology.

Enthusiasts really drove the mapping/chipping of the 94-96 Impreza ECU, which was made easier by the spare location on the ECU main board (Rally reg's at the time stated that the ECU could not be changed, therefore it wasn't, but another map could be run from the spare slot). For 94-96 ECU once the map locations within memory were understood...bob's you uncle.
The influx of what was supposed to be an obsolete blank chip (fujitsu 271028) from hong Kong (assume these are grey market copies) also enabled supply to match and maintain demand.

The 97/98 ECU was a bit more tricky and although it does have the ability to run a adaptor board i understand that there was some sort of 'scrambler' chip involved which made it even more tricky. Plus it only really covered approx 1 year so the demand wasn't really there to justify the investment.

 

From what i know is not possible via any SW,as above people suggest aftermarket ECU or ESL daughter board are only solution to do properly.

ESL just released the board for the V2 and 3's. Been in touch with them as mine was an unmappable V3. About £500 fitted and mapped

 

Blimey Scott, where have you been?! Living under a rock?

Good to see you're still 'on the scene'.

 

Thanks a LOT guys.
SORTED with him :-)

 

Seent this posted so many times

Any proof ?

 

Thats a good news mate because i have been waiting for it to be realised. If its realised for V3 then V4 will be sorted because they are praticly the same ECU, who will be selling these ESL boards?

 

The ESL is available for the 97/98 now, And there working on anti/lag and launch as we speak, It has switchable maps aswell, According to ESL there available to all mapper's, I just waiting to book time of work and will see if simon doing them :-)

 

Sorry to.hijack but i just checked which ecu i have and it has sti on it when its a 97 turbo coupe uk how is that possible?

 

any link to ESL? never heard of them

 

This is there f/b page http://www.facebook.com/pages/Enduri...d/341833312224

 

And website http://www.enduringsolutions.com/

 

ESL are pretty epic to be honest, good boards, good functionality and bloody good value for money.

 

I have seen a thread with a 1997 RA using the new ESL running MAF-less. It was only fitted and mapped just over a week ago.

 

I am intressed on the ESL i would keep eye on this thread, please update it when you guys any more info in regards to ESL. i have spoke to Simon who advised me that its on early stages for V3/V4 so he will be able to answer more questions once he has done few of them, i was goin to use Apexi on my new build 2.5 but i think i going to wait and see what the outcome of the ESL on modded cars. i like the idea of having AT/LC and have switchble maps without breaking the bank

 

As pointed out before mate, have a look on Facebook if you are on there
