Preguntas frecuentes
Do I need upgraded fuel injectors or high-pressure pump?
On stock turbo engines, factory injectors and HPFP typically handle E85 with +20-25% duty cycle headroom. On aggressive Stage 2+ tunes, upgraded HPFP or larger injectors are recommended.
Will the car still start in winter cold temperatures?
Yes. Softechpro specifically recalibrates the sub-zero cranking enrichment and post-start idle ignition timing maps, resolving typical ethanol winter cold-start issues.
