Honda civic type r losing power on 6th gear

[Yashvin95]

Good day,

After tuning my fn2 I see it is losing power when I try to accelerate uphill on 6th gear.

Please see attached log. It is towards the end of the log.

Kind regards

It is running out of fuel. So fuel pump, fuel filter, fuel cap, fuel injector problem is most likely. Could be a bad ECU injector driver, but by far the most likely cause is the fuel pump or fuel filter.

Hi there. Thanks for the reply. The car doesn't do this with the stock map on. Only after the tuner loads his map it starts to lose fuel

In that case provide the calibration. It must be very lean.

I don't know much, but a couple things stand out. Here's what I see.
default on the graph- injectors never get over 41% and the ignition timing seems to be locked at about 28*
cam angle- Do you have VTC on decel set to 0*, smoother shifts can be had setting it to follow the cam.
errors- alternator seems to be charging a bit low compared to 08 civic si. Mine charges above 14v.

Hi there,

Please see attached log of standard map. This will give us an idea if it's the tuning or the car.

Kind regards

That datalog shows the opposite - very rich under full load.

So it is not the fuel system as I initially thought. It is the calibration.

Sorry Yashvin95, I'm just starting to learn how to read my own datalogs. Still have no idea on the tuning side, just what I have gone through. Are you running stock injectors?

Hi there.

Yes car has stock injectors. Only have an exhaust system on the car.
