Live injector values
Hi all
Have had a proper scan tool today to check values of my injectors. Number 1 was 866 and 2 was 775. But the other 4 were around 1020 upwards which is quite a difference…
I was wondering are the first two a bit low, or the rest too high? As they seem to have a difference of 200
See images
I’ve also attached images of the boost and pressure control etc. And wondered if someone would be kind enough to let me know if anything looks off. If so what please?
And thanks as always!!!

The acceptable range is 700 - 1300 at idle with a hot engine, yours are all within spec.
The tuning is pretty fine, a good run (>30 miles, no traffic) will see the values change to closer to 1000 unless there really is an issue - which I doubt TBH
ETA - why did you have this done? is there an underlying concern or is it 'just to see'?

Just re-reading your reply I see you sent a question back sorry….
I had been getting an intermittent code of cylinder 1 fuel pressure too low. About once every 2 weeks. So I had connected that with a recent injector replacement on cylinder 5 and wondering if cylinder 1 was on its way out maybe.
I’ve just done new engine oil and main battery and had the chance to get codes read as I knew it was a wise idea to bring on here for a likeminded DIYer like me haha

Well firstly I wouldn't take the DTC as pointing to the exact injector causing the issue, it would be an idea to re-test the offsets as near as possible to the conditions you get the DTC set in.
I'd also do an injector leak-off test as this can be more indicative than reading live values alone.
Bear in mind that the live values are at idle so won't have much influence when under load.
If I indulged in guesswork, I'd say the issue is likely to be with cylinders 3 or 4 as they are close to the centre reading, the other cylinders are working to balance each other out. Proper diagnosis is needed though, especially if you are getting a DTC set and it's reproducible.

Diagnostic Trouble Code - 'fault code' - you mentioned you got one for injector pressure low.

Ah thanks
As I say it was a code for cylinder 1 fuel pressure low not sure if it’s actually in relation to injector. Also not had the code come back in 2 weeks now
