Hondata

Hello!

As of this year, I have been participating in 1,600ft roll racing events in which my speed exceeds 159mph. I have noticed the VSS stops logging at 159mph, although my speedometer will continue to climb (wired to a SpeedoHealer v4 on a JDM CTR cluster, making it a 190mph speedo). Is there any way to allow the VSS to see over 159mph at the ECU? I am finding at the top of fifth gear, when the VSS is maxed out, the per-gear trims bounce back to 4th gear way up top.

Also, I have limited the boost solenoid to 95%, although it does not increase over 90%.

I have attached a log of both of these on a run from this past weekend's event.

Thank you for any information!

Currently there is no way to do this. I do not know if it is something that can be changed in the future.

"No" to both?

How is the K-Liner/all the other Hondata land-speed cars seeing VSS? Or is the VSS not even referenced?

Thanks for the fast response!

Can you post your calibration and a datalog showing it being limited at 90%. I cannot reproduce what you are describing.

The ECU internal speed is limit to 255 kph. The gear compensations will use the 6th gear compensations above this speed.

I figured out the 90% cap problem. Total rookie move on my part, and forgot I only have 90% maximum defined in the lookup table.

As far as the VSS goes, you can pretty clearly see in the log I posted the gear compensation move down at high RPM from 5/6 to 4.
