Performance Tune for 2538 HST

Snowback · Sep 22, 2016

I know, I know - no such thing.

BUT - anyone with an early model 2538 HST from last year should check with their dealer to see if they have the new updated programs loaded on a laptop. My machine was running great, but the throttle has always seemed a tiny bit sluggish and "bouncy". I chalked it up to the new electronics. After this new flash it feels just like my old Max that had a mechanical throttle linkage. Instant response and no more modulation or "shaking" of RPM after a position change. Definitely a very nice improvement for me.

This may be something for all new Tier IV owners to think about from all brands. The brand new electronic systems are probably being tuned and updated continually, and if you don't get your ECU update flashes you're just missing out on free fun!

It only took about 15 minutes and they did it while I was picking up an implement this afternoon.

Did mine about 3 weeks ago. Tractor runs smoother. The glow plugs stay on a full minute now. Not sure they need to stay on that long but I always give it time to warm up anyway.

Funny you mention that. I just noticed the glow plug deal this evening while moving sand for the kids' sandbox. Started up and actually turned it off after about 30 seconds as it always went right out before. Tried again and off it went right about a minute in. Interesting.

Agree 100% on new performance. Sure is smooth now. Amazing what these new engines can be made to do, (or not do), with a good or bad tune, eh?
