v8bobber Posted August 1, 2012 Share Posted August 1, 2012 Hi, I have a 110 with an early "10p" type engine. I can get hold of a later "15p" engine. Will I have any compatibility issues? The ECU is what concerns me most Regards, Dave Quote Link to comment Share on other sites More sharing options...
martifers Posted August 1, 2012 Share Posted August 1, 2012 Won't be a problem. You should input the new injector codes into the ecu anyway so will need someone who can write to ecu to do this, if there is anything else that differs (don't think there is anything important) then they could alter that at the same time. My Defender suffered from gender confusion for while after an engine transplant done by previous owner. Was fine but the ecu kept throwing fault codes as it was confused as to why it didn't have discovery bits anymore. Had it flashed when i did a full re-wire with no problems. You can pretty much do anything with it, with the right tools or friends. Quote Link to comment Share on other sites More sharing options...
v8bobber Posted August 1, 2012 Author Share Posted August 1, 2012 Hi, Thanks for the information. If it is that easy then great! There is a garage down the road which I think has all the kit to do the work. It's literally a half a mile tow down there, or will it run after a fashion? I have heard about injector numbers etc, do you have to physically read the numbers off the injectors or would the garages equipment be able to read this Dave Quote Link to comment Share on other sites More sharing options...
martifers Posted August 1, 2012 Share Posted August 1, 2012 I believe it will run of sorts with the incorrect codes. You have to read the codes off the injectors themselves. By just removing the cam cover enables you to see them (takes 2 minutes) Quote Link to comment Share on other sites More sharing options...
v8bobber Posted August 1, 2012 Author Share Posted August 1, 2012 That is encouraging. So to summarise then, ANY Td5 will run with ANY ECU as long as I take it to the man with the machine down the road and get it plugged in? Dave Quote Link to comment Share on other sites More sharing options...
Ridgeback Posted August 2, 2012 Share Posted August 2, 2012 The ECU between early and late versions is different . The early ones are not flash programable like the later versions. I have been talking to a few of the tuning companies about getting my td5 mapped and asked about upgrading to the later ECU. They can flash the later ECU with the early files but I don't think you can go the other way. I have also been told the ECU between defender and disco is a little different, I think it was the fuel would read backwards, it would however run the engine. If your getting a later engine, I would just make sure you have the matching ECU. Might be worth talking to someone like Gary from Alive tuning or Ian from IRB developments to confirm.

Dave No... a 15P Engine needs to be on a NNN500020 or NNN000120 ECU. You can put a flash (NNN) ECU onto a 10P engine with the correct software, but you can not go the other way (i.e a MSB***** on a 15P). There are a lot of differences between 10P (EU2) and 15P (EU3)! As a quick test to make sure it runs, just use your current ECU - I wouldn't even worry about injector codes. But I wouldn't suggest driving it any distance with the wrong ECU and injector codes.

martifers Posted August 3, 2012 Share Posted August 3, 2012 Didn't realise EU2 ECU's didn't run on 15P Engines. Assumed was compatible with a replacement chip. Glad people in the know came along. Porny has done all our ecu work and knows his stuff. Quote Link to comment Share on other sites More sharing options...
