Why would you want to know that, is it not running properly? Injection pulse is produced by the ECU, I believe it's a digital signal that is varied by software so should not be subject to deviation from what is needed unless a sensor is giving the ECU duff info.
well ive just had the adaptive values reset,the injection times are approx. 4ms.i am trying to fix a "idle trim out of range error" on both banks which keeps re-occurring.lambda sensors are "switching"fine but the engine just seems a tad rough.of course I could be looking for pots of gold at the end of rainbows.......or I may have an issue.hence the question.

The pulse width seemed a bit long to me too... It was me that reset the adaptive values,dont worry all the usual culprits are spot on - Maf was 23.5 Kg, well within the parish etc. I've not got any black book values of injector pulse width for Thor motors - never needed them before.I cant really compare with Gems data either as they run a fixed fuel rail pressure of just over 50psi.
Did it run any better on the way home ?

Maybe that's the cam ? I know its more expensive,but running on petrol for a few more miles will help get all the trims sorted.Then you can trim your gas after a recheck/refit.
Also forgot to say to check the flexplate isn't cracked.
