Help in identification of ecu please??

[Donato]

My car was imported a couple of months ago, i don\'t have a lot of imformation on it as i can\'t read japanese!!

I know its got a arc airbox and an aftermarket intercooler with hard pipes, a knights boost controller, and an extra dash gauge for fuel mixture (which seems to run slightly rich 99% of the time, which i understand it should).

From reading other posts its become clear i should have an upgraded ecu. I don\'t know if this is the case, is there any way of identifying the my ecu by serial no or name or other means???

Cheers

Hey Donanto

Sorry if this sounds patronising, its not meant to be

I assume you have located the ECU and it has no markings/names on it anywhere ?

Might have to take it off to find out

Dave

[Donato]

Not patronising at all,

erm i think i have located it but i may be looking at the wrong thing, engine bay at the back on the ns??

[davefrith]

its on the left in the passenger side footwell mate

the plastic trim where your left foot is when you sit in the passenger side

Take that plasic off and you can\'t miss it

Don\'t know what the hell i was looking at then :confused:  Will have a look now...

[Donato]

Right here is the ecu

[davefrith]

hmm looks like its made by border, ROM usually denotes Read Only so maybe not a programable one

some one else who knows more about these jap parts could probably help further, I haven\'t seen a Border one before

Dave

[Donato]

Ok mate,

Cheers:)

It would appear to be a Border ECU.

Its not likely to be mappable, but even if it was who do you know here who could map a Border ECU?  Oh well then!

Its likely to be customised and checked towards the mods already on the car.  Id say you shouldnt change too much or you may have trouble with it, not knowing exactly what it does or the settings.

Thanks guys,

I\'m not intending to change anything at the moment, or at least until i get it on and rr on 1st feb that robbie is organising and find out what power i have at the moment, after that i will probably want more!!

I just wanted to make sure it wasn\'t a standard ecu with the mods i have....from the condition and running order of the car it appears the previous owner knew what he was doing but i just want to make sure.

When i bought the car the guys at Jvs said not to take the boost control over 1, what do you reckon is safe to run at? Or is it impossible to tell without knowing more about the ecu?

If by 1 you mean 1 bar, then stop where you are.  Otherwise stock turbos will be inefficient, injectors wont cope, fuel system wont cope...

Dont do anything to it untill you at least know what you are starting from

Its not worth trying to eek out 10hp for blowing an engine.

Sorry didn\'t make myself clear, yeah 1 bar, but i have never ran it at that, it usually sits between 0.8 to 0.86 for everyday use, and when i want a bit more i set it between 0.9 and 0.94, i have never taken it above that, i just want to make sure that even 0.94 is ok??

[davefrith]

you need to make sure its not running lean at low boost let alone higher boost mate

get it to a specialist with a wide band sensor and get it checked asap

Personally I would do that before I did anything else, especially thrashing it on a rolling road

Dave

[Donato]

Even at low boost according to the fuel mixture gauge it is rich, but i will get it checked out.

Thanks again for your help
