Well it don\'t look too healthy.

Can\'t you put your Black ones Ecu on it just to see if it makes any diffrence?

[grinder]

i thought of that matey - but dont want to blow that up if something is majorly wrong

it a wonder that this thing ran - maybe i should have checked this first !! LOL

i just hope someone has one that fits

and just paid for some coilovers - so now im POOR

Stu

[arrouk]

i would say that is prob shafted

Its posable that it could have got wet? may have worked you never know.

I would be tempted to put the ECU of the black on on it but if you are a big Girl :yes put an add in the Wanted section and do the E-bay thing there always comeing up, of course every one wants to upgrade so there not worth alot.

Would it be worth taking it to an Electrical repair shop (you know the type of place that do TV\'s) and see what they think? it may be repairable?

Stu you have PM.
 
Just out of interest - did you get a pic or can you get a pic of the ROM chip - it will be about 3.5cm long, 1.5 cm wide and will have a label stuck on top with some writing or printed words - and maybe a 4 digit hex code.  It will have 28 pins, and is on the board with the larger chips on it.  This is the code that makes the ECU an N374 or N380 or Knightsports or whatever.  It looks like someone converted an older ECU to a Knightsports one, so you can\'t go by the numbering mate.
 
If the ROM chip is socketed I can probably make a copy for you and convert another ECU to a knightsports one - as the legs on yours may be a bit corroded.

[grinder]

oh christ - i hope they havent converted an old one - i will have no idea what to replace it with ?!?!?

i can get pics of the chip - and yeah its about 28 pins - looks like a plug and play item

Stu
( quick hunt now to find out what i do have - this could be fun )

another ecu list i found :

ECU Part Numbers (this is the version # that\'s on the ECU itself)  
84-85  GSL-SE  N304 18 880A
86-87 NA N326 18 880, N3Y6 18 880
87 Turbo N332 18 880
88 NA N327 18 880
88 Turbo N333 18 880
88 Convertible N338 18 880
89 NA California N350 18 880
89 NA Fed. N351 18 880
89 Conv. CA N352 18 880
89 Conv. Fed. N353 18 880
89 Turbo N370 18 880
 
NOTE - If there\'s an "R" at the end, it\'s a remanufactured ECU. They also change the last 3 digits to "881". Example - \'89 Turbo Reman. - N370 18 881R. A remanufactured ECU isn\'t necessarily bad; it DOES mean the ECU was replaced.
 
and no 374 ??

I think the only thing that may be a problem is its Auto, i\'ve swaped ECU\'s around from car to car in the Past (they where all S5 Turbo\'s and Manual though).

I know the EMS that was in my 1990 Manual Vert was defo a N370. But as i say being an Auto may mean it has a diffrent Part number? But looking at your List it would seem not?

Stu, email me.  If all else fails send the ECU to me and I\'ll repair it for you

[Prof]

Depends on how bad the corrosion is.  When water sits for a time on the PCB, the remaining flux on the board is dissolved and begins to eat away at the component legs and pcb tracks.  This can weaken them.  Also, if water gets into components like coils and capacitors, they will most likely need replacing.

It may be repairable, but for peace of mind it would be better to swap the eprom onto another ECU and be assured you have a good one.

One thing to be aware of - it looks as if water is leaking onto the ECU from somwhere - you might want to track that down PDQ Stu !

[antnicuk]

rust eh........ that will be mazda\'s trusty softop,   you can trust it will always leak!

[Mobilemick]

put the ecu on your running one,  see if it starts


naa  better not  lol

Can u repair any ECU`s Brett

[sadgoth]

problem with a lot of the lists of ECU part numbers is they are US lists, remember the US did not have a turbo cabrio and for some strange reason, they seem to deny its existance on the US forums! They\'ll talk about the JDM turbo II and the European turbo II but never about the Turbo cab!
