hi all,ive just bought a scoobyecu and im fitting it to my z4ecu later,i know you have to cut the j1 resister but do you need to cut it completly off or just the wire side?

cheers eddy.

 

just cut the long wire side so that it could be put back as standard if you wanted to,were did you get your chip and how much

hi m8 i bought it off a guy on here but it looks like brand new,dont think its been fitted before,cheers for your advice.

eddy.

 

i have a z4 and u8 so i could get one and see how it goes,let me no how you get on ,good luck
matt

 

does fitting the scooby ecu leave the check engine light on??

 

No.

Rob

 

If it's a genuine ScoobyECU board or a 27C1028 chip and they are running Impreza base code (rather then Legacy), then the check engine diagnostics should work as normal.

Cut one side of the J1 resistor or remove it completely. If you need to go back to standard just replace the J1 reisitor with a wire link, as the resistor is 0 ohm and hence the same as a bit of wire.

 

where can i get a scooby ecu/chip? cheers

 

Put something in the wanted section and keep an eye on ebay.

Rob

 

well one of my mates did the soldering for me,and when i put it back in car it turns over but theres no noise from fuel pump,and engine check and engine managment light isnt comin on with ignition were as it as did before.so i took it bak off to see if i could see a problem with it and noticed that to of the fibre wires have come off.so i gave it back to him to take chip off and he cant get it off.hes made quite a mess of ecu really,is there anyone that will beable to fit this chip for me when i finally get hold of another z4 ecu.(not askin my mate again).


cheers eddy

 

it has the same number on it mate (27C1028)

 

if its been made a mess of take it to an electrical store. they may be able to remove and test it for you.

Very difficult to get out of the ECU if it's been soldered direct.
It is possible if you have a heated solder removal tool, but that's really only found in electronics manufacturer's. Even then there is a risk of lifting the copper tracks.

I don't even know if TV repair people use them. They tend to use a manual solder sucker and a soldering iron.

Due to the ECU main board using PTH (Plated Through Holes) it's very difficult to get the chip back out (Hence why a socket is normally used).

The easiest way to get the chip out is to cut all the legs off then suck the remainder out of the ECU board holes. But obvioulsy you end up with a knackered chip with no legs.

 

bloody hell sorry to hear about that

 

well i managed to get chip out undamaged,but ecu copper tracks had lifted,does anyone on here fit the chips for a price,as i will have to buy another ecu now i could do with someone who knows what there doing to fit it for me!

cheers eddy

 

any idea were i can get one of the sockets from that can be soldered on to ecu then plug chip in?(i dont know technical term for socket)

cheers eddy

 

It may look undamaged, but the heat required to remove it may of also damaged it.

If you are going to buy another ECU get a V7, 6D, 7D or 7K
All of these have sockets already fitted, so just plug the chip in (the correct way round) and cut/remove J1 link.

 

i thought it had to be the same ecu (a z4)with my car being an import.

cheers eddy

 

95 wrx import(sorry forgot to mention the year)

 

You can pretty much bung any ECU in if your chipping it (though best to steer clear of WRX Wagon ECU's 1C, 3B, V5, V9).

Your car will run fine with most of the WRX Saloon or UK ECU even without the chip. But obvioulsy the performance will vary due to the slightly different mapping (11.47psi UK & Early WRX Vs the Z4 12.7psi).
Don't run any STi ECU though as these run lean and aggressive timing.

V7, 6D, 7D or 7K would be fine as they are already socketed (although don't run the 7K without the chip, as it's an STi ECU)

2C, W6, U8, W9, Z4, Z5 or 6K would be fine but they are not socketed, so would require a socket to be soldered in (although don't run the 6K without the chip, as it's an STi ECU)

Most of the cars re-mapped in the UK run Z4 base code (including the offical Prodrive map) as it was the least buggy and one of the most recent released.

Your Z4 may still work without the chip despite the damage.

 

cheers mate is ther anywere to buy these ecus or do you have to wait till one comes up for sale?

 

Try http://www.japperformanceparts.co.uk/ or http://www.gradea-subaru.co.uk/
Or Ebay, but not this one http://cgi.ebay.co.uk/SUBARU-IMPREZA...QQcmdZViewItem

I've got no idea what thats off, as the bracket and connector is compleley wrong for a 1994 WRX

 

cheers m8 thanks for warning me about that one on ebay ive just been looking on there,ive just made an enquiry to one guy on ebay selling one off a 93ra import but there was no model/make name.

cheers eddy

 

just one more question for scott.t,when ive got one of the ecus you mentioned and got chip fitted do i need to do a full ecu reset with the male and female connectors under steering colum? as ive read this on another thread,but i was told you only need to reconnect the battery,could you just confirm which is right for me please!

 

No ECU reset would be required. If the ECU has been off the car for about 20mins it will of reset itself anyway as it only has limited memory storage time when un-powered

 

thanks for all your advise scott.t been very helpfull

cheers eddy.

 

Flippin' 'eck eddy! You've had a few problems here.

Is the Scoobyecu I sold you still okay?? It's the original type so pretty rare to get hold of now.

David

 

hi david yes the scoobyecu is ok need to get a ecu now

 

I thought Scott Taylor used to do a fitting service (or was it somebody else well known on Scoobynet). You used to be able to post your ECU to them and they would fit the Scoobyecu and post it back. T'was quite some time ago though.

It's very dissappointing that you are having these troubles. So much for plug 'n' play.......

David

 

i know not much i can do now though till i get ecu,i thought it would av been all sorted by now.but if you find anyone who fits them let me know eh!

cheers eddy
