Auto Throttle Advance - Adjusting
- Thread starter DonRICT
- Start date
Can't help with the thread but the adjustment is under your right foot. There was no adjustment left on my l5740 so I could not change it.

Woah there, the adjustment is NOT under your foot, those are the hst stops and shouldnt be messed with. The adjustment you want are the cables on the passenger side of the engine compartment. The thread you want is here

Actually there are adjustments on either end of the cable and no I was not referring to the peddle stops.

If it's the autothrottle you want to adjust then I wouldn't touch the HST pedal. The autothrottle has it's own cable, it may have adjustments on the lever side under the plastic below the steering wheel but I never removed it to look.
Here's the picture I took (and has made it around) showing the two cables under the hood.
Although the picture makes the cables look silver and gold (not sure why it came out that way, maybe I had the flash on) they are actually the same color.
With the engine off open your hood, the cables are on the "passenger" side. Using your had push down on the HST pedal and you can see which cable moves, it's the other one you want to adjust. On mine it was the lower cable in the picture. If you look you can see the upper cable is roughly centered while the lower cable has almost no threads showing on the black protective coating side.
The lever the cable pulls is made so that either cable can pull it but when pulled it will not effect the other cable.

Thanks, arsenix2001, for the pointer.
crazyal your picture, + copy was a big help.
Took my time, about 15 minutes, to adjust. Tested in a couple positions 'til moving the adjuster all the way forward.
My cable was the bottom one also, and was all the way rearward too. Must be the factory setup.
What a difference. Now, in rabbit hi, I go 5 mph at only 1750 rpms, instead of 2200 rpms.
Started using my ATA right away. Now it is much more useful, IMO anyway.
Thanks guys.

OK I am confused:confused2: which way did you adjust yours to slow it down if it was already moved back.

I think what he's saying is that his was factory set to the highest RPM extreme, & he adjusted it to the far other end, i.e. the lowest RPM extreme. That's what I did (almost), too. I think there may be 1 or 2 turns more that I could've moved mine to make the RPM's even lower when pushing the HST pedal with Auto Throttle Advance engaged ... but I'm happy with mine where it is.
