Hi All

I am new to this site. This is a great forum. I wish I had found this sooner.
I have a 75 914 with a 2.0 I am attempting to tune. I have an old Penske 21018 CO meter I would like to use. Does anyone have experience with this tool? I would like to get a copy of any instructions if there are any to be had.

Thanks

Mark

I have an old Behr unit....has a lightening fast 286 processor that I upgraded to a 486...woohoo...more power.

I found the "STupid book" online after a Google.

Tuning with an analyzer takes a lot guess work out the equation....

The Penske unit I have is an analog unit. It looks real simple. I am hoping I will give some meaningful readings out of it. I tried to use it and there was only a small movement on the meter.

Pretty sure the single gas units need to warm up for twenty minutes....
