Daniel B has been a tuning pioneer in the 10th gen Honda Civic community specializing on the Hondata platform. Pushing the envelope while setting milestones with Ososik "Si Se Puede" CivicDaniel has been able to take that knowledge and experience to create stage tunes for enthusiast at all performance levels.

Our 10th gen Civic Si Stage 2 tune was created in 2017 with the Ososik Civic and refined throughout the years utilizing Hondata's latest software features. This tune has been tested to be reliable and track proven. The dyno plots shown on here were created using a new 2019 Civic Si with only one modification, a Siri-Moto Flex Fuel Kit with a 40% ethanol blend (CA 91 Octane & E85) on a dynapack. Our Stage 2 tuning strategies allow you to safely run any range of ethanol percentages you desire, optimizing the full potential of your flex fuel kit. ***Flex Fuel Kit is Required with this Tune (sold separately).***


- Stock: 182 HP & 217 TRQ

- Stage 2 (E40 Blend): 247 HP & 305 TRQ (w/Clutch Slip)

*Final stage 2 peak gains could not be seen due to stock clutch slip. However we thought we'd send it and share what happened.

You must provide your FlashPro Serial Number during checkout in "Order Comments" section!!! Once purchased all tunes are emailed within 1 dayIf you do not provide your FlashPro Serial Number there will be delays in receiving your tune. An aftermarket clutch is highly recommended. Having Bolt-ons and better cooling will result in additional power and torque. Our top 3 supporting mod recommendations with this tune would be a high flow downpipe, intercooler and cold air intake. NO REFUNDS once transaction is complete, please review your order!!!
