To cut a long story short, I've been struggling with an overheating car for the past year, only to find out that my tuner wiped the base timing setup before he tuned my car, and now it is tuned with the base timing approx 6 deg retarded, which I think it why I am struggling with heat (trust me I have eliminated all of the usual suspects)
My question is, if I was to keep the same ignition timing table but correct my base timing, how at risk of knock would I be? I don't think it is set super aggressive as is.
Ideally, I would like to monitor the next time I'm out using the OEM knock sensor. Is this worth doing or am I better off moving to a Bosch donut style sensor?

For info, BP4W, with Chinese 2871r, at around 16psi. Car was pretty down on power off the dyno too, which is what makes me believe I had a timing issue.

I'm open to suggestions as to why this may not be the cause of my issues, and if anyone would be willing to take a look at my tune I will gladly post it. ]]> Link leftright https://www.miataturbo.net/link-130/base-timing-knock-111227/
