The last ingredient for TOTB ...

 

Rotflmao!!!

 

Sounds like Jon has found some 1028 eproms, which are what the ECU was designed to take. If the map is anything like mine it should work fine, I would at least find out what sort of boost target it runs, sensitivity to fuel etc.

Knocklink adviseable still, not a bad idea on a standard car even of that age as they were designed to be run on 98RON SUL no the 97 we currently get.

so just who's map is it?????

jon recon's its his own........

 

I have a map of Lancashire, could that be it ?

 

Update for all those WRX Wagon owners that thought this GB might be the light at the end of the tunnel (as I did). Spoke to Jon today and he doesn't have a map for import wagons

David, Pavlo
I know the idea was bounced around a few months ago, but any chance one of you would be willing to develop a map? Last count there were about 15 import wagon owners up for one plus several volunteer guinea pigs to help test a map, I reckon if we got something solid together you would probably get more orders than that.
Or is there still a supply/time shortage?

I have a good ScoobyECU map, for a TD04 wearing JDM wagon of the MY94 vintage. 17 PSI peak boost, aggresive spooling but no fuel cut.

If the developer doesn't object, I could ask for it to be forwarded to some one who could burn EEPROMs of it?

Got me 256 bhp / 256 lbft at well lane a few weeks ago ... TD04 was limiting factor then.

Let me know and I shall ask if they will allow it.

 

I thought Jons map fitted all cars? Seems like it doesnt matter if its a TD04 or TD05, uk or import, so shouldnt his map work on wagons?

Seems like people are crying out for scoobyecu or any ecu they can put in their import

 

I havent really seen any comments from CustomScooby about some of the issues that people are having?

Can CustomScooby shed some light on boost, fitting, and some of the problems that Pavlo mentioned?

e.g...overboosting etc???

Oh yeah, how do we pay?

Just as im off to Turkey this weekend and wont be able to reply again until i return.

jon is getting the chips checked by API engines so should be soon!

 

I have indeed spoken to Jon re getting a chip to try [ not Fry ] However, at API we are the engineering nuts and bolt-sters and have no expertise at all in electronics and leave it to the experts. So PLEASE don't start asking me/us questions about the mapping and so on - I am just interested to try one and see what effect it has, with the possibility of perhaps advising customers of another way to get their cars off the 100 ron det problem that JDM cars suffer.

We often try out stuff, anonymously if we can, to try to be able to give customers an informed view of the benefit or not of certain parts.

Not anonymous now then David!

At least less "risk" for you guys to try it than the average go faster punter / JDM owner.... and plenty of spares to hand!

 

David, have you tried out the VOS chip?? I would be very interested in the results of that.

I have one and was thinking I would like to RR the car with it and without to see the difference, and see if it solves the fuel issue too as it's supposed to.

 

David as posted is trying one of the chips Julian, as posted above mate.

Jon

 

David/API are trying Jon's chip, not the VOS chip .. which I read was a mini board and chip in a very small package ( not just a simple chip). The original ecu mods were a single chip but hard to come by, hence the scoobyECU board which put 2 smaller chips together to emulate 1 proper chip.

You could still do a before and after VOS / Scoobyecu / customscoobyiom ecu upgrade if you run wih it and then disable / remove it ... should be 1 simple wire to join.

 

No I dont use an adaptor board, I use the single chip method. The ScoobyECU uses the twin chips (Even and Odds) and an adaptor board.

 

I thought you used a small PCB with the 2 adaptor boards mounted on it in a single 28pin format. Or are you saying you are using an actual Eprom?

Paul

 

Wasn't it the VOS chip that was a micro adaptor ( 2 slivers of silicon on a small board, epoxy'd into a chip package ), replicating the original Subaru design / scoobyECU style re-chipping?

Sure I read it on here somewhere that someone had taken a VOS apart and found that ...

 

Just been reading the topic and wondered how to put my name down for one. Can only get 97 ron fuel from miles around where i live, could be an engine saver for me.
Cheers

 

OR KILLER GOING BY SOME PEOPLES COMMENTS

 

so this is NOT a scoobyecu???

 

nobody knows what it is apart from jon!

 

v.interesting thread....
Strange that there's no Wagon map yet tho'
Pavlo, David, surley you must have a Wagon map by now, as I must of done at least 5 wagon variations with good results, no det, no limp home and about 15psi.

Now where did I put that map....hmmm...shame.....I seem to of mis-placed it
Oh well at least no-one can rip it off !!!!!!!!!

It's amazing what you can do with a Eprom reader, Hex Edit and a handfull of 27C1028's. But hey isn't that how we started ????????
Are they coming from Alex in Aus by any chance, as I'm after a few of blanks ??

 

ScoobyECU was the name that Pavlo, David and myself called the adaptor (seen at www.scoobyecu.co.uk), which had 2 opto-isolators and 2 27C512 chips which split the code into ODD and EVEN bytes. This emulated a 27C1028 which was the correct chip for the spare socket on the 92-96 ECU.

27C1028 chips went obsolete in the early/mid 90's hence the reason to emulate them with the adaptor.

I did manage to locate a batch of 27C1028's through another member and he shipped them to me from Aus. However as these chips are now very old and have been lying around for some time, I was finding that some would not program/read or even work as expected. Hence this was another reason why I pulled the plug at the end of 2003. Although David and Paul continued with the ScoobyECU adaptor.

Therefore the use of the name 'ScoobyECU' by CustomScoobies is not strictly correct, as it appears they are supplying 27C1028 chips.

When I started using 27C1028's, which was for about 50 of the 85 that I sold. I changed the name to 'ScoobyChips<96' and advertised on the ScoobyNet shop as such.

As mentioned above I stopped this late 2003/early 2004 so please don't approach me expecting any maps or hardware for your ECU

 

thanks for clearing that up scott

 

No problem,

I could post up all the problems and issues I saw with the various ECU types and car set-up's. But that would just be far too useful !!!!

Especially as there seems to be a nice variation of ECU's on the list

 

Thanks for the info, jon has said that the chip is his own and not a scoobyecu or a variation on one. So i haven't got a clue where they've come from.

 

This is a product that everyone wants, yet the best results must surely come from mapping the individual cars.
Can anyone do that?

A few can

Cheers
