garymorris Posted November 20, 2019 Share Posted November 20, 2019 I’m going to change the engine in my 52 plate disco, my question is do I need to get another engine which is the same P (ie 10P ,15P) or does it not matter and I can code the injectors using Hawkeye thanks in advance Gary Quote Link to comment Share on other sites More sharing options...
Simon_CSK Posted November 20, 2019 Share Posted November 20, 2019 Gary I have changed my engine twice and doubt I kept the Ps the same. Also I have never coded the injectors and both engines have run fine. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 22, 2019 Share Posted November 22, 2019 They are supposed to be different between 99-01 and 02-04 model years, but to be honest I don't know what the differences are and whether an early ECU will run with late injectors (or vice versa) I really don't know. The injector grading is fine-tuning, so it probably depends on whether you're a perfectionist or whether you're happy with something that just runs.
