Hey up Daren. .

No. You aren't insulting me, and I don't know about my Vast knowledge, ( it's all a bit blurred most of the time )

That's why I like to ask if I am not sure, and try and get an explanation that sinks into my thick skull,
But in this case, If he has programmed all 4 injectors with any code,

How does the ecu know whether he has coded them in the right order or not. ?? Surely It just knows that he has entered some values that it recognises. ( right or wrong ).

Then I would think that as you say after 100 miles or so, if he has done it wrongly. it will log a code. ??

Not cause the code not to erase in the first place. ??

>>>Edited after thinking about it and talking it over.<<<

Ahhh, is that the problem. ?? Has Dave only programmed cylinder 1 and 4 and not the other 2 ???, When he actually needs to recode injector no 2, that would explain it and that's actually what he put in his first post, if I had Read it right )

As I said earlier, I had started to Type a reply to Dave about injector Order, But I then changed my mind and deleted it as I thought it wasn't relevant, But it is if he has only entered the data for 2 injectors, then it is very relevant. ( I usually enter all injector codes whilst I am doing the job ), But as i now know that it is not actually doing anything, apart from allowing it to erase the code then i might just start entering one injector code as you have mentioned to me before.

See it's good to Talk. Thanks. Tony.
