John tarantula Posted October 13, 2011 Share Posted October 13, 2011 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) Quote Link to comment Share on other sites More sharing options...
M13KYF Posted October 13, 2011 Share Posted October 13, 2011 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 Quote Link to comment Share on other sites More sharing options...
John tarantula Posted October 13, 2011 Author Share Posted October 13, 2011 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? Quote Link to comment Share on other sites More sharing options...
nixy Posted October 13, 2011 Share Posted October 13, 2011 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) Did you get to the bottom of the 'is it or isn't it' question then?

John tarantula Posted October 13, 2011 Author Share Posted October 13, 2011 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 Quote Link to comment Share on other sites More sharing options...
bigsigh Posted October 13, 2011 Share Posted October 13, 2011 would a uk ecu work in an import of the same year plug and play ? Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted October 13, 2011 Share Posted October 13, 2011 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 Mark Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted October 13, 2011 Share Posted October 13, 2011 would a uk ecu work in an import of the same year plug and play ? 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.

Hope that helps Mark 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 Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted October 13, 2011 Share Posted October 13, 2011 Nope you need to read ECU number from ECU code via OBD port Quote Link to comment Share on other sites More sharing options...
John tarantula Posted October 13, 2011 Author Share Posted October 13, 2011 OK, well was worth a try! looks like I'm going OBD port hunting! Thanks for your help! Quote Link to comment Share on other sites More sharing options...
Dblock Posted October 13, 2011 Share Posted October 13, 2011 any real gain or loss jdm's not having a wide band sensor? Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted October 14, 2011 Share Posted October 14, 2011 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. Quote Link to comment Share on other sites More sharing options...
