Ute — Stage 2 ECU Tune
- Improved fuel efficiency
- Improved power output
- Improved torque delivery
- Enhanced boost control
- Optimized drive by wire response
A 1938 Ford ute running a 383 stroker Chev small block with Edelbrock heads and a mild roller rocker cam. Customer supplied it with a Holley Sniper engine management system already fitted, along with upgraded injectors and a high-pressure fuel pump feeding 98 RON.
The goal was to dial in the Holley EFI tune to better match the hardware. We worked through the fuel and spark tables to clean up a few flat spots and sharpen throttle response without chasing outright power. Workshop dyno recorded 220 kilowatts and 520 newton-metres at the wheels, up from 215 and 515 respectively.
Not a dramatic shift on paper, but the driveability improvement was the real outcome. The T700 transmission benefits from smoother torque delivery, and the engine now pulls cleanly through the mid-range where it spends most of its time on the road.
Why such a small power gain on a Stage 2 tune?
The stroker combination was already making solid numbers. This tune focused on refining fuel delivery and ignition timing to improve driveability and consistency rather than chasing peak figures.
Is the Holley Sniper platform straightforward to calibrate?
Yes, it's a capable standalone system with good tuning flexibility. We adjusted fuel tables, ignition curves, and closed-loop parameters to suit the mild cam and head combination.
Will 98 RON be adequate for this combination long-term?
Absolutely. The mild cam and compression ratio suit pump 98 well. Timing is conservative enough to avoid detonation risk in typical Australian summer conditions.
