Robert,

Congrats on a job well done. It sounds like you're ready for the ASE test!

Have a great day,

You lost me there, can you elaborate on that comment?

Capt...

I removed the little resistor that's attached to the A/C line. It's the one that compensates for lower octane fuel. I use ONLY 92 octane, so I removed it.

The car is driving SO well. I can pull out without fear now.

Cap'n,

Robert is referring to the ignition advance resistor that is discussed to death in the Performance Paddock.

The long and short of it is; there is a resistor ty wrapped to the a/c line near the master cylinder. When you remove it, you add 6 degrees ignition advance. On Euro cars there is a rotary switch that allows adjustment for varying octanes. On the US cars, this resistor retards the maximum ignition advance for emmissions reasons.

There is no real downside to removing it because these engines have a knock sensor that prevents preignition problems.

My $0.02,

I've been meaning to mention this with every post I've made in this thread and continue to forget.

If you don't have a duty cycle meter, but you DO have an old dwell meter, you can substitute the dwell meter for the duty cycle meter when setting the lambda adjustment. You simply look for mid scale on the dwell meter. All a dwell meter is, is a duty cycle meter marked up in degrees instead of %.

Have a great day,

Thanks Larry!

I had gone back in a search and found that info. On the dwell meter subject.. What numerical readings would you look for on the scale, 45-55 degrees? I have an old Sun dwell meter, let's see... I loaned to my friend Clark back in 1984 I think!

You will be looking for half scale which is 50% duty cycle. For example. For a four cylinder, max scale will be 90 degrees. This means that 45 degrees on the four cylinder scale will be 50% duty cycle.

I actually dug out an old Dwell meter and experimented with it. It was reading exactly center scale on my 300E pin 3. I didn't know whether or not to trust it at the time, so I bought the $27 meter. It confirmed that my lambda was set at 50%. This gave me confidence in using the dwell meter, but now I had the duty cycle meter so I didn't need it.

Hope this helps,
