Chip tuning to fix death lag?
Hi! I'm a mechanic who works mostly on BMW, VW, and Toyota. I've seen enough 21st century Hyundais to consider them generally good cars, so when I flew across the country to see my grandparents who need a new car, a gently used Hyundai became almost the default choice. Uncharacteristically for old folks, mine want as small a car as possible - they still miss their 87 Civic - so an Accent is the prime candidate.
I testdrove a '17 Accent automatic with 18.5k on it. Everything about it is acceptable or better, except the acceleration lag. At first I wondered if it was stumbling due to an intake leak. A few hours of forum research showed that while the Sonata hybrid is the worst offender, many recent Hyundais have some degree of death lag.
Is there a chip tune that can fix this?
