Chevy Cavalier & Pontiac Sunfire ECU Tunes & Ecotec Parts
SBR Performance specializes in custom ECU tunes and bolt-on performance parts for the Chevrolet Cavalier and Pontiac Sunfire. Every tune is built on a real chassis dyno and proven on track, never a generic, copied file.
Cavalier & Sunfire ECU/ECM Tunes
Whether you run the 2.2L Ecotec (L61), the 2002 2.2L push rod (OHV), the 2.4L Twin Cam, or a 2.4L Ecotec bottom-end hybrid, we have a tune for your setup:
- Email tune, $149: you read your own ECU, we email the finished file back in 24 to 48 hours
- 2003–2005 Cavalier/Sunfire Ecotec: Automatic, pre-tuned ECU
- 2003–2005 Cavalier/Sunfire Ecotec: Manual, pre-tuned ECU
- 2002 2.2L Push Rod Cavalier/Sunfire: pre-tuned ECU
- Mail-order custom tune: send us your ECU
Email tune or mail-in? Here's the difference.
If you already own an HP Tuners MPVI interface and read and write your own ECU, the email tune is the fastest and cheapest way to get an SBR calibration. Nothing ships. You buy it, send us your stock read plus your mod list, and we email your finished file back, usually in 24 to 48 hours. Your car never comes off the road.
No interface, or you would rather we handle it? Then a pre-tuned ECU or a mail-order tune is your path. Same calibration work, we just do the reading and writing for you.
Hornet Class & FWD Circle Track Racing
The front-wheel-drive Cavalier and Sunfire are two of the winningest cars in hornet class and four-cylinder stock car racing, cheap to buy, tough as nails, and fast when they're set up right. SBR-tuned FWD cars are in victory lane at dirt and asphalt ovals every weekend, and we race what we tune.
A proven hornet class package looks like this:
- A pre-tuned, email, or custom ECU tune matched to your fuel, your mods, and your class rules
- A ported 60mm throttle body, stock appearing for tech inspection
- The balance shaft elimination kit, less rotating mass, more usable power
- The safety fuel rail, protects the Ecotec's known fuel line weak point when you're door to door
Racing under a strict rulebook? Tell us your class rules when you order and we'll keep the tune legal for tech while getting everything the rules allow. And grab our free RaceSetupPro setup guide to dial in the chassis, too. See what our drivers are winning with on the customer photos page.
