ECU differences - JDM and UK??

[John tarantula]

Do the JDM and UK models have different ECU's? if so can you tell by any stickers / markings on the outside? still trying to figure out how much has been chanegd on my import as most stuff seems to be UK (apart from the VIN no and V5)

yep for a starter JDM's are limited top speed to 112

 

moved to the correct subforum. Have a dig around in here for the differnces

[John tarantula]

cheers,

 

haven't managed to test out the limiter yet but wondering if there were any visible differences on the ECU. Mine has MY Nissan writen on it on first glance?

Did you get to the bottom of the 'is it or isn't it' question then?

[John tarantula]

not really, partly hence this question! the paperwork and VIN says JDM but everything else says UK so if it is a JDM then it seems lots has been changed to make it look like a UK car

[bigsigh]

would a uk ecu work in an import of the same year plug and play ?

[Mark@Abbey m/s]

I dont think a JDM ECU will code up (NATS) to run in a UK car but I havent tried it to be honest;

 

UK car has a 155mph speed limiter.

 

Easiet way to work out what ECU you have is to read the ECU number with either Consult or a Uprev system;

 

DE UK car will have ECU 23710-CD700 for a cruise car

23710-CD800 for a non cruis ecar

 

JDM cars early will be either 23710- CD405/406/415/416.

 

But all the UK car's are wide band lambda cars but all JDM cars upto 09/2005 where narrow band lambda cars. So these ECU's wont swap over.

 

Hope that helps

only late DE JDM ECU will work in a UK car but we need to turn a few CEL codes off in the ECU as there are wiring/component differences.

thanks mate! next problem is my OBD port is missing (!) so can't connect anything going to pull that side of the car out tonight to see if it's been tucked away... Are any of the above numebrs actualyl written on the ECU as I can get to that fairly easily

[Mark@Abbey m/s]

Nope you need to read ECU number from ECU code via OBD port

[John tarantula]

OK, well was worth a try! looks like I'm going OBD port hunting!

 

Thanks for your help!

any real gain or loss jdm's not having a wide band sensor?

[Mark@Abbey m/s]

not really , you cant just fit wide bands to a JDM car thou.

 

Really only a issue when tuning as we cant datalog the AFR via the ECU on early JDM cars.
