My tuner called me in to get a retune because the last time he tuned my car his dyno was reading 12% too low. A good result I think. We worked on the VTEC crossover point and the AFR around there and a bit of a fiddle with the AFR up top. The car feels different to drive now, no more dip just before Vtec.

The new power curve.


The old power curve.


Much of the leaning off was done by the fuel, we have a couple of new premium fuels that have more oxygenates in them.

Sorry, I had a question. Do you think the AFR is safe?

This question is for the experts out there. Being a 4th gen with OBDI do I have to worry about LTFT?

On my VAFC2, the tuner has set the low throttle setting to 10% and High throttle to 50% (factory VAFC2 setting). Is this ok to leave it like that? Or will my OBDI ECU detune the car?
