I can't get above 23. Even hwy is 22.x I think I noticed this after adding the code3 intake- that's why I wondered if an earlier post with getting too much air could cause this? I will remove the code3 intake and see what happens. I am sure after I did the sc pulley, I was getting 27 mpg on the hwy.

Please correct me if I'm wrong.

More air needs more fuel to create more power. Right?

If you are traveling at 70+ mph, you are probably running right at or above the S/C clutch threshhold (it kicks in at 2900rpm or 40% load, whichever is first). This means you are running the S/C and sucking more air/fuel tooling down the highway.

By the way, my stock C32 has gotten over 23 mpg once.

That adds up. I just haven't messed with the fuel. On another car (turbo) I own, I ended up doing complete ECU, fuel injectors, intake etc. I just thought
I could get away with not yet needed the extra fuel- always some project to
work- aside from the house honey do list.

Time to look at the fuel and search the forum.

Even prior to the Code intake and LET tune, I routinely got 23-25 on Highway and once saw 26. I did this by staying OUT of the SC (which is hard to do). If you can run about 68 MPH, you should see 25 easily.

Well... in your sig., you mention having an LET tune. In your post you mention "haven't messed with the fuel" - which is it?

ECU tuning primarily addresses spark timing advance and fuel maps (among other things) - so if you have a modded ECU tune, you most definitely have 'messed' with the fuel.

sorry for the noob question but is the sc clutch programmable? Is it possible to change it to (f.e.) 3500rpm or 40%?

To the best of my knowledge, no.


I would defer to someone like Vadim @ VRP for the truest answer though.

Jerry told me that it IS somehow. How, I didn't ask. In addition, there is also the possibility of having a switch to totally turn off or disengage the SC. I really like that thought BUt do not know how it would affect longevity of the SC or the engine (sucking air??) I 've heard of someone in GA running a SC on/off switch getting about 30 MPG on theirs??

There is a free and easy way to do this. The problem is that you need to open your hood to disengage/engage the S/C. Jerry showed me where the control plug for the S/C was when I felt that my S/C clutch was acting up. By unpluging the wires leading into the electomagnetic clutch, you too, can have a wildly expensive C320, that performs more like a lawn tractor. I did not have the patience to find out what the mpg would be.

By the way, I don't know what you were thinking , I was referring to being able to keep the speed down to 68.

I know you were, all my numbers are in Warp speed as in 68 is 6.8. OK Picard???
