Re: again with FN348 Cranking Pw ECT questions
Posted: 2022 Jul 05, 16:51
OK, here goes, one last question.
offset is a range of (voltage) values and cranking typically pulls my little battery down to under 10v (bounces between (more than 9v, less than 11v).
There is a considerable difference between my old offset and the new one at that voltage range (from .44ms at 9v, .37ms at 10v up to .32ms at 11v).
If I shoot for the 10v middle and add .37ms to the .42ms that worked for me before (25% higher than the calculated pw considering engine and injector size), that would take me up to .79ms cranking pw for ECT 160 and above.
Am I doing the math right? It does seem like I'm a bit short on fuel while cranking but am a bit nervous about adding that much more. Am I at risk of doing damage by adding that much more pw and potentially overshooting the mark?
