has anyone tried those ecu upgrade chips that you find on ebay?sposed to raise boost pressure to 16psi,alter fuel maps and allow you to run imports on ordinary superunleaded fuel.personaly i aint bothered about uppin the boost just interested to know if they do actually let your car run safely on our crap fuel.anyone had any experience with this??

I don't think you will find anyone who has experience of these 'chips' on here. You should stay well clear of this kind of thing. Talk to one of the respected mappers on here if you wish do any upgrading of your ECU. If you use one of these you could really do some damage.

I have just ordered one of these chips according to the description it raises fuel cut and the fuel and ignition are remapped to adjust to the increase in boost target and the guys feedback looked pretty good from other guys who have bought the product.
When i get it soldered in i will have it booked in for a rolling road session just to see if the car is running ok and if not the ecu will be reset and is easily removed.
Will post a thread and tell you all how i get on

subaruhonky

i will be very interested in the results.like you say it can be easily removed so as long as you get the car checked to make sure everything is cool,it shouldnt cause too many issues i reckon.

philbr

i've got a scott.t@polar performance chip on my v1 and no problems at all.

must say that of all the chips, he is the only one who actually lists different maps for different cars, all the other ebay sellers just say yes mate it'll fit and work.
don't know which one bought but be careful and be prepared to remove chip again if you get ANY warning lights, if you cut the resistor don't remove it in case you need to go back to standard,
cheers phil.

Just for the record and for the few of you that be-little 'ALL' of these upgrades in one statement.

I have been supplying upgraded chips and scoobyECU adaptors (the adaptor is not required if you can get a genuine 27C1028 chip) since 2002.
In that time I have supplied probably near on 400 chip upgrades for 1993-1996 Impreza of all variants. Most of which have been to fellow Scoobynet Members without issues.

The ScoobyECU Adpator was initially produced by myself, David Wallis and Paul Blamire (now MD of Zen Performance), back in 2002 as a result of getting together way back then (there's a DIY mapping thread on here somewhere).
We started with our own cars, then mates, then mates of mates, then other Scoobynet and SIDC members.
Over the years creating maps for 'ALL' variants of thre Pre96 Impreza Turbo, WRX, WRX RA, STi, STi RA, WRX Wagon and Auto.

I have also supplied in that timing ECU ROM Image information to this forum. However, this I regret as some of this info has been used to my disadvantage, by other recent chip suppliers.

After I found a source for the 27C1028 chip a few years back the ScoobyECU ceased production as it was easier to programme the chip the have to build the adaptor.

The name ScoobyECU was one that we came up with back in 2002 and should only refer to this adaptor and nothing else. Perhaps we should of trademarked the name...but hey what did we know we were just a bunch of enthusiastic egg heads back then.

Of late a supply of 27C1028 chips has become available from 2 sources. Both of which I beleive are based in Hong Kong. Hence several people have jumped on the band-wagon and started knocking out chips with some form of ECU ROM image loaded onto them.

As to whether they work on all variants is anyones guess. I'll leave that for someone else to find out.

I'm hoping to ride out the storm as expect the source to dry up again at some point.

However, I do have other mapping options available for 1993-1996 (I am an ESL Dealer, see Enduring Solutions Limited) and am also able to live Remap/Reflash 2001> cars (see PolarPerformance)

So it's not my only form of providng a service to the Subaru community.

generic maps arn't worth the risk.

every car has differences and the same map on different cars can be inccorect afr etc so stay well clear

Scott.T@PolarPerformance

Sorry but the AFR tables are followed quite well by the ECU if you stay within safe limits and the modifications on the car are fairly basic.

You will find that most tuning houses have a generic map that in alot of cases they make very very minor changes to during the rolling road session.

I know because I have had it done to my own car.
After ripping the maps out of a standard OE ECU (with a Generic ECUTEK Map) then my remapped ECU (Reflashed for Exhaust, Induction and Turbo Change), I found that the changes that were applied were minimal and didn't really justify the £300 charge for the re-flash.

Some car specs are different and the mods and boost target requested by the owner are beyond the abilities of the selection of remapped chips I can supply.
For these I suggest live mapping, but in more cases then not they bulk at the cost (Around £550 - £600), in some cases probably 1/5 of the valaue of the car.
They then probably end up fitting an FCD and a MBC and do no listen to my advice
This has got to be alot more dangerous for their engine life expectancy.

Tidgy

then how come the map from my car doesn't work on a car with exactly the same mods?

Scott.T@PolarPerformance

Whats the map, whats the mods, whats the car.
It could be a car related fault
TBH 99.9% of the issues I see end up being related to an issue highlighted on the car. Normally coil packs, plugs, dirty or dieing MAF or boost control plumbing issues.

MAF failures are quire common. I have attended several RR shoot-outs and during these there is normally someone with a Pre96 WRX/Sti that either needs new coil packs or the MAF is causing fuelling issues.

Tidgy

BOTH 00 UK CLASSICS, DECATTED (oops caps lol), pannel filter.

ran rich on mine, lean on his, was rolling roaded with his existing ecu and was running sweet as, was only when my ecu went on that it was an issue. his old one went back on and it was back to being fine again

Scott.T@PolarPerformance

How long was his ECU off the car for between his and your ECU runs ?

I reckon the chip should be ok on my car it is a 1996 wrx import and has been serviced recently with no issues and a recent cam belt was done.
I have very light mods (panel filter and rear silencer) and because the boost is only raised by 4 psi i reckon the standard pump injectors and fpr should cope well so i have been told)

But like i said to be safe i will get it rolling roaded after fitment to ensure all is ok

I was just wondering when the j1 resistor is cut is it easy enough to resolder it back if i do have an issue with the chip and i need to put it back to standard?

Tidgy

about a week, if that.

shogo10

iTrader: (1)

Oh in addition i do give my maf a clean and test every 2 weeks.

Scott.T@PolarPerformance

If the J1 is refitted or a wire link added the car will run the OE ECU base map without issues. I normally fir a small socket to this location so the owner can swap out if required.

the esl chip is what i've had in my car for some time. tidgy you know how quick my car is

i've never had a problem at all with my car (no engine light or anything)

the live map being even beter, as it is a proper map.
know what i need to know is.

can you still get these old esl boards set up, as i know have a front mount on & need it setting up proper.

there is nothing wrong at all with these chips. once done we'll see what bhp this car really has!

shogo10

iTrader: (1)

Can you remove the j1 connector or do you need to cut it in order for the chip to take over?

dabow

iTrader: (19)

you cut the j1 so the new map can take over. but all the cars functions are still all standard, all safty features ect

i've never had any issues with the chip in my car
& the car runs quick & quiet.

Scott.T@PolarPerformance

The only people I know that may re-work your ESL board are ESL or PTS who ESL were in partnership with.
although ESL may shy away from it as they are trying to push the live mapping.
The cost/labour of messing with the old boards in order to get a good bespoke map is almost as much as the live option.

dabow

iTrader: (19)

i would like the live map board & map. but have a little issue at the mo with the car, its in genaral section

but my funds will be taken up with that.
+ with the car playing up, i wont be able to get the car there as the tax & mot have just ran out

Tidgy

dont forget bud not seen you since it went pop

dabow

iTrader: (19)

it diden't go pop

i put the front mount on.
the engine still pers as quiet as hell.

i had probs getting all the hoses in red, so i kept it off the road till know..

Tidgy

not seen you for months mate lol

dabow

iTrader: (19)

i'll be back on theraod soon mate.

just have to sort this little issue out with the scoob.
frantic revs.

ask chez, the cars getting there. & its pering like a kitten

Tidgy

lol, be good to see you mate, been way to long, mines slightly different since you last saw it as well lol

philbr

i've got one on my car full exhaust/induction etc and works tremendously, thanks scott

dabow

iTrader: (19)

my point exactly

know just need the fund for the live map board

subaruhonky

bugger,stirred everyone up now aint i ! well i reckon ill give it a go soon,should hopefully be attending a rr day soonish so i think ill put the chip in just before and get the tuners(triton motorsport) to check everythings cool.
