Ag'merica exists because agricultural tuning is its own discipline. A tractor doesn't work at peak RPM, a combine can't wait two days for a dealer opening, and fuel is the input you buy every single day. We calibrate the machines that have to run when the window is open — and we come to the farm to do it. Our sister company, Dynamic Tuning Specialists, is the Fort Wayne bench behind us: the same master tuner, the same tools, the same Viezu file access. Shop work is by appointment at 137 Chambeau Rd, and on-farm service runs anywhere within 100 miles.
Not a static off-the-shelf file. An ag engine controller holds well over a hundred tables that decide how your machine behaves — fueling, air, torque, and the governor that ties them together. We open the ones that matter for the work you actually do, change them deliberately, and log the result on your machine.
Fuel is the input you buy every single day, and it's the one a calibration can move. BlueOptimize™ is Viezu's own economy-tuning programme — the software behind their Queen's Award for Enterprise, independently tested at the Millbrook proving ground, and available for cars, vans, trucks and tractors. As an authorized Viezu dealer, we write it on your farm.
Figures published by Viezu for the BlueOptimize™ programme. Real gains vary with the machine, the implement, and how it's worked — which is why we measure on yours rather than quote you a number off a chart.
Watch particles flow from engine to tailpipe. Each stage adds cost and complexity.
Ceramic honeycomb trapping soot particles. It has to burn clean at around 1,100°F during a regen. Short cycles, cold weather, and low loads prevent proper regen — soot builds until your ECU forces a parked regen or cuts your power.
Tap each stage and watch your power, speed, and productivity drop in real time.
We don't have a dyno, and we don't sell you a peak number. What matters in the field is what the engine does when the implement loads it up: how far the governor lets speed fall, how fast it recovers, and whether it holds PTO speed at 540 or 1,000 through a heavy pass. That's governor and torque-curve work — verified with datalogging on your machine, under your load.
Nothing gets calibrated before we know what the machine is actually reporting. We pull codes and freeze frames from every controller — engine, aftertreatment, transmission, hitch and PTO — with OEM-level tools. From the seat, a DPF pressure fault and a bad DEF quality reading are identical: both just take your power. On the scan tool they're two completely different repairs.
On-site tuning and diagnostics anywhere within 100 miles of Fort Wayne. Your machine never leaves the property and never waits in a line at a dealership. Shop work is by appointment at 137 Chambeau Rd — and for mobile work, contact us for pricing.
Ag'merica is the agricultural arm of a working calibration shop. Dynamic Tuning Specialists has been tuning trucks, cars and diesels out of Fort Wayne for over a decade — a 100% tuning shop, an authorized Viezu dealer, and the bench where every Ag'merica file is written. If it isn't a tractor, that's the door to knock on.
The Magnuson-Moss Warranty Act prevents a manufacturer from voiding your warranty simply because you modified the machine. They have to prove the modification caused the specific failure they're declining to cover.
Every calibration we write is fully reversible — your original file is saved before anything is written, and it can be put back. Results vary by machine, implement, and how it's worked, which is exactly why we measure on yours instead of quoting you a number off a chart.
