Haltech Elite 2000 vs 2500 Comparison
First, 1xxx vs 2xxx series ECUS…
Elite 1000 is a 4 injector 4 ignition ecu. Best suited for 4 cylinder engines but can be used on more cylinders (Example wastespark, semi-sequential V8)
Elite 1500 is an Elite 1000 with advanced features added.
Elite 2000 is an 8 injector 8 ignition ecu.
Elite 2500 is an Elite 2000 with advanced features added.
Now on to the comparison… (The list will refer to 2000 vs 2500, but same statements can be applied to 1000 vs 1500.)
- 2000 and 2500 both do true flex fuel, advanced boost control, traction control, launch control, rolling anti-lag, etc.
- 2500 has Drive By Wire, 2000 does not
- 2500 has OEM CAN support, 2000 does not
- 2500 can control 4 variable cams, 2000 is limited to 2 variable cams
- 2500 has better logging – more space, channels and speed
- 2500 has 4D tuning for fuel, ignition and boost control for max customization
- 2500 has multistage nitrous control, 2000 has single stage nitrous
- 2500 has 5 race timers, 2000 has 1 race timer
- 2500 has transbrake control and co2 wastegate control
- 2500 has short and long term knock control, 2000 has short term only
- 2500 can be upgraded to T (2500T) box if required in future. Mainly used by dedicated drag cars, example X275.
- 2500 has multistage engine protection allowing different responses to different problems. 2000 has single stage, so all protections trip the same response. For example an Elite 2000 lean protection will trigger the same protection as low oil pressure or low fuel pressure.
