Dumb question........

WIth the EECIV you pull the spout and set the base timing at 10*, by the manual.

 

With the Holley it will not idle at 10*, currently to get it somewhat stable I'm around 25* in the map.

 

Using the 16x16 maps seems to be a lot better for initial adjustments than the 31x31.  IAC is high so I think I need to open the throttle blade or put the belt on it.  The discharge was not on it during the first round before the distributor mishap.

Once the fuel and air is right, it'll idle at 10*. Get out the vacuum gauge. Start working the mixture at idle (just grab an 8x8 area and set them all the same). Once you get max vacuum from the mixture, then you can start backing down the timing and the idle airflow.

Oh yes. You won't use that stuff until the tune is getting close to right. Otherwise you'll just mask problems rather than correct them.

Below is the current fuel and timing maps:

Should I set an 8x8 fuel to what 3lbs/hr, that is about where it was idling, along with the 24.6 cells on the timing map?

Still need to check the Inductive delay again and verify the timing, which is hard when it will not idle at 10*, I guess I could bump it to 20* and see if it will idle there and check it, just have to mark the balancer again.

Yes. Or whatever fuel it likes to idle at. Don't look at the Wideband when doing this. Listen to the engine, watch the vacuum (MAP sensor) and watch the tach. As you approach a good idle mixture, RPM will go up, MAP will go down. Then you can drop timing down some if needed. to drop RPM. Timing = torque. So if you are at idle and need more otrque, you can give it some timing.
