Need to borrow it please if poss. Want to make sure the xr3i isn't running too lean. If anyone knows or can recommend best value for afr I'd appreciate that too.

Had it tweaked after swapping 3 injectors to cure irregular misfire on light throttle. Now 99% better but could do with being a touch richer.

Cheers chaps

 

Morning people!

 

take it to msd for a fueling check? wont be that expensive i doubt

 

They'll probably want near on 80 quid for set up. It was tweaked by wayne at chip wizards when he did injectors. But it could do with being a touch richer as it still coughs lightly when touching throttle. I know they were never perfect. Just wanted to make sure its not too rich now I've adjusted it.

Drives perfect now.

 

Sounds like you've compensated for a transient issue by richening it up globally (affecting it all over).

 

3 injectors were unsatisfactory. I saw them on the test bench, one was borderline. The other two were way out. He swapped them for some spares he had and refreshed em. The fresh set were all identical and good spray pattern.

Apparently they always ran a bit lean from new, but this was amplified by the bad running I had, I suppose if richening a touch smooths everything out and makes it drive well then it should hav been like that from new.

Just don't wanna wear bores out or anything prematurely.
