Yeh there was a pwm of 1.96khz. I had 99% soc at the time. The change to 20% in setup mode made no difference that i could see. I'll have a look at the code myself but it's taking a while to catch up

That said it did work yesterday as i mentioned but then reset itself to full. I do suspect the fuel gauge computer in the dash is partially to blame. I'm looking out on ebay for an old "smiths" type fuel gauge that i could mount in a dash pod and use for testing. Sadly , they command a high price nowadays due to popularity in kit cars.
