yeah but motors are inductive loads so it would require a diode.

Well only way to find out is to put a diode on and try it of that it worked for a while then crapped out then the second one died almost straight away don’t want to kill to many of these at 50 bucks a pop could start to get expensive quickly

Ok so collected a new relay same unit as before but I’ve also got a diode to fit to the motor as well I got a 6a10 diode as far as I can tell that should be a massive overkill for what it needs (better to be safe than sorry) is that correct or should I have gone with a different one?

Should be overkill, though I'm not sure if speed of the diode matters or not? that said I have used plain 3A rectifier diodes in the past with no issues.

Well driven it a few times now and the new relay hasn’t died after fitting the fly back diode so looks like that was issue only issue now is mainly hunting once hot at idle stationary I have to sort out will have to get a log and have a look

probably lean or the VE table has a spike or, I know on the V6 they deliberately made the last 2-3 cells of the inverse temp term table really cold so to overcome lean out issues when the manifold is heat soaked.

I have removed that before and they tend to hunt once heat soaked or after a hot restart. From memory the V8 tune never had that fix.

Cheers I’ll have to have a look once I get a log and a squiz at my tune to see what’s going on
