Tuning Update for January
Hey everyone. As some of you may already know, we have a rather large update to release this month. Matt and I have been talking tonight, and we felt it necessary to make a post regarding this update before we actually release it to the public. The rest of this post is Matt's....
We originally had our latest tuning database update scheduled for release this afternoon, but due to damaging some electronics used for testing over the weekend, we will need to postpone release until later into the week to get the new hardware in and the last parts of the update fully tested.
In light of this, I thought I'd use the next few days to give a more detailed description of the changes and updates to the calibrations we will be implementing, and get some input and consensus from our users on any other changes you guys would like to see. Our current update includes the following---
-Shift changes to all 250HP tunes (milder at part throttle and enhanced converter lock)
-Shift changes to all 275HP tunes (milder at part throttle and enhanced converter lock)
-Changes to all HP levels to correct late lock-up issues for 2010 and earlier trucks with 3.55 ratio gearing
-Addition of 300HP tuning for Job 1 trucks
-Correction for customers seeing periodic cold weather part throttle surging with 275HP tunes
Another update will shortly follow the one mentioned above to include---
-Updates to both engine and transmission files for ALL Spartan TCM calibrations
-Engine calibration changes to 250, 275, and 310HP files to address periodic rolling idle
Any input from our customers on any issues will be monitored closely, so feel free to throw it in here. Even if it isn't a technical problem and is just something you'd like to see (tuning related) post as you'd like.
