One of the latest features added to FlashPro, live tuning gives you the ability to tune your Honda or Acura on the fly without switching off the engine. Live tuning simplifies part throttle tuning and significantly reduces the time and cost of tuning your car.

A look at the extensive datalogging capabilities of the Hondata FlashPro. You can view all engine sensor information in real time and record up to 20 hours worth engine data displayed on your own laptop based customized instrument panel. We show how you can use datalogs from the built in wideband to help tune your air fuel ratios. View in HD and full screen to view the screen shots.

What sort of improvements can I expect?

The tune is designed to give a conservative yet exhilarating 10-20% improvement in performance. More powerful than the 17 Civic Si turbo.

Your Accord can gain anywhere from 10 to 40 hp everywhere,  with the maximum gains not at the top of the rev range, but where you need it most at the low end of the rev range. Rapid acceleration is just a quick flex of the throttle pedal away. 91 or higher octane highly recommended, but not required. Testing done on 91 octane.

Accord 1.5 CVT

Stock - Orange

Stage 1- Red  No extra peak hp, but peak power 500 rpm earlier.  20-25 hp gains midrange and 20 lb-ft torque

Stage 2 - Magenta 11 peak hp , 30 midrange horsepower and 40 -50 lb-ft midrange torque

The CVT is difficult to dyno, so we are using the MT dyno charts. The CVT was tuned to similar boost levels for the MT for stages 1 and 2.

Accord 1.5 6 MT Stage 2

Stock - Orange

Stage 1 - Red  No extra peak hp but 20-25 hp midrange and 20 lb-ft torque

Stage 2 - Magenta 11 peak hp and 40 -50 lb-ft torque

Stage 3 - Silver 13 peak hp (40-45 hp midrange)  and 50-60 lb-ft torque

Stage 3 may need a clutch upgrade depending on driving style.
