Ignition Timing

[GSUjinih]

So I was doing some data-logging with my Q and saw that it was running about 69 degrees of advance at 70mph with light throttle. This seems to be a really high value. Also it appeared that at idle there was 45-50 degrees of advance at idle? Is the true value -30 degrees from the actual? What is causing these high values?

Which tool are you using to measure timing? The tool I use shows 45 when I'm actually at 15 - hence the 30 adjustment for use on a US model..

I was using a tool like this: http://www.ebay.com/itm/260714039312?ss ... _774wt_708

Strange how it adds 30 to the original value, as with my 240sx it shows the correct value. Also is the Injector Time LH double the value it should be?

What is the typical maximum advance at 70mph with light load? Also is the injector reading correct?
