Is this normal for Tach Readings using TunerPro ?

Is your dash tach still not working? I thing you need to look at the white wire going to the coil for the distributor tach signal. Also look at the wires that were ripped out when your radio was stolen, you need to get a wiring schematic to check out the tach signal to ecm pins. What other dash gauges are not working??

BIG MIKE !!!!

The only thing not working is the TACH.

I did take the dash out and cleaned the contacts, took a look around but still dead.

I wasnt sure if the signal was the same going to the gauge as the computer.

I was just wondering what everyone elses tunerpro scans looked like if that was normal to see the RPM fluctuations when accelerating. I would expect to see a smooth transition upwards except for a shift.

could be too much alky and causing just a slight miss

I see you have Alky Control also.....

On the Alky Control I have the following settings.

I have the Turn ON set to about 10 o clock

Initial is about 12 o clock

Blue knob is set to 6

Does that sound ballpark for settings ?

every application will be different. I would start by turning the knob on the controller down just a little and see if it makes any difference on the tach. Do you have an ignition box (msd) ?

I agree, tighten the gap on your plugs. I had trouble with stock heads spraying until I gaped my plugs down to .28.

Using Summit Digital IGnition box.

I am using Autolite 103's gapped at 28. They have been in about 500 miles.
