hondata with cobra cai race

Yup been fighting this for close to 3 months now.

Even using factory airbox and using the factory ecu WITH adding 2-3 gallons of ethanol at one point im still where you are trim wise. (Just monitoring the ECU returned to stock running factory tune with flashpro)

I have no answers.

Here's to hoping nothing deeper was being damaged in the computer/ coding while tuning.... but alas i can't say what the deal is.

You won't get an answer or suggestion from hondata.

Just guess and test and cross your fingers?

Yup. I sent datalogs to Hondata and was told that my fuel trims look "normal".

I'm glad I held onto a KTuner. As soon as I have full support for my ECU I'm switching back.

It's a shame, because otherwise I have loved Hondata. But this fuel trim thing and lack of a solution is driving me insane.

Lol I've seen STFT as high as -25 under normal conditions. It's like the injectors are just pissing fuel into the cylinders regardless of throttle.

Interesting read, sorry to hear you're having those issues. Just curious, nothing else was done to cause the sudden change? How does everything else look on the datalog? I noticed in your signature you have a Stage tune, have you tried using a Hondata basemap with the PRL Race mod and then datalogging (you never know).

Now I know i'm a little late to this but has it been resolved?
If not...feel free to PM me.

@r.camlin I think adjusting the low range airflow in the 0-10% throttle area would help with this if it is not a mechanical issue. My initial suggestion would be from 2-10 g/s within the table, reduce by 5% to start. It may want closer to 10% reduced. That area always runs negative for me.
