You cannot alter fuel, ignition, error codes. You cannot change anything associated with the secondary oxygen sensor. You can alter boost because we retain the stock Honda code for providing fuel and ignition at the different boost levels. Here's how to do it. Edit the torque tables:
This is correct. The race versions has more options. We have switched from the + 6 and + 9 pro calibration designation to a torque based designation. This makes it easier to tune a flat torque curve and stay well under the clutch slip limit. The torque tables (and boost tables) can be raised for...
Anticipated questions. "Why is this less than the preliminary tune?" " What's with the names?"
Clutch slip is related to peak torque, not power. Our calibration has a little more power than the preliminary tune but less torque. Hondata chose to engineer flat drivable torque curves to reduce the...
We have been working hard testing and developing the CARB tunes for the 2022 Civic Si. The performance gains are huge with a simple upload from our Plug-N-Play FlashPro system. Our Si now has over 1,000 miles and the development was done with California 91 octane.
Yes, stock and highish boost, but not the maximum possible boost. So, yes, there is headroom. I'll go into detail on release.
Thunderhill engines - unknown. An engine swap from a street 22 Civic Si into one race car crossed the finish line.
Hondata CARB tune - technical
For those of you who are new to Honda and are considering the 11th generation platform here’s a quick primer on Hondata. Hondata was founded by two enthusiastic Kiwi CRX owners who wanted their cars to go faster. We’ve been providing Honda tuning solutions for well...
We re-visit the dyno Monday/Tuesday next week to incorporate what we have learned into release calibrations. Our calibrations are driven and tested daily in our own car with our own experienced staff. Expected release about 2 weeks.
To be accurate, Hondata measured 222 hp. To be even more informative Hondata measured this as a 10% power gain over the 10th gen using an identical ramp rate of 500 rpm per second to minimize the effects of rotational inertia.
Rev Hang is emissions related. The technical description is injector overrun cutoff delay. The injectors keep firing for a short time after throttle closure to reduce the oxides of nitrous pollution.
Switching this off is illegal for any CARB / EPA tune and for any road vehicle. This is...
The car will stay stock as we test out the calibration and assess the turbo and other engine characteristics.
I have questions:
With all this extra torque, how well does Honda’s VSA handle the wheel spin?
What are the knock and boost limits?
