Post by alex_ctr »

Hondata,
i have a Euro FK8 Type R with Rampage 450 R Turbo, Flex Fuel System running at 32-34% of ethanol blend and the Hondata Upgrade Fuel System.
The car is run very well at 1.9-2 bar of boost without issue but a few time at 5700 Rpm on 4Th Gear the Throttle Plate close at 55-60% with Foot Pedal at 100%. I have try with Vsa Disabled and traction control Off but this don't solve the isse.
The throttle plate close and the boost pressure go down for a little time..

It is from VSA. As far as I know you can't separately disable the vehicle VSA/TCS. Enabling the Hondata traction control will help.

Sorry to bring this old topic but this is happening to me with just the 91oct Hondata tune (with Hondata traction control disable), my engine is completely stock.
The solution is to use the Hondata traction control or there is some other thing to do besides turn down the torque request?

Thanks in advance

Help me just to understand what is going on, in 4, 5 and 6 gear my car is not loosing traction (is a stock car and the tires are in good condition just with 91 octane calibration) but the throttle always close bringing the boost down, why the VSA is closing the throttle when I'm in WOT? Shouldn't only activate when losing traction or in corner stability?

I tried and upload a calibration requesting lower torque (450) instead of using Hondata traction control and it keeping doing it, just doesn't make sense.

Isn't any map in the original Bosch calibration with a torque limiter for VSA operation?


Thanks I just want to understand with this is happening

I did not Sir, because doesn't make sense for me sorry, i'm not loosing traction.

Does the Hondata traction control disables the VSA control over the throttle plate? If yes I will try the traction control option.

Another thing there's 2 options on the mod list regarding traction control and when I check one the other check appears as well is it normal like this or is some bug?

I'm using the latest version available 4.1.5.0
