I Was tuning my Low Cam, Part Throttle. So i decided to Enable the LEAN Protection Feature, and Re Enable VTEC at 3000 RPM, so i could Tune the Vtec Map. When the motor accelerates to 3000rpm it would not rev past that rpm. Moved the VTEC point at 4000rpm. Also have the same issue. Also disabled the LEAN Protection, and I have the same issue. Is there anything i should i check? ALSO to be noted I had another TUNED Map, Switched over to it, and Everything seems fine. Boost Fine, Vtec is fine.

it should be something in the mapping or some parameters could be wrong like lean protection...the wiring etc...

I unchecked the LEAN protection, but somehow, even tho unchecked, i think it is still in place.... wiring is good, because it works with another map.

if it seems aunchecked you can try changing the offset of the wideband sensr under settings... For example write down 2 or more value if you are not having a target AFR maps also.. than it won't be able to get lean value from the sensor...

Okey While data logging you can lock wanted cells You should be able to unlock them also:) If you can not change those setting than your cal file may be corrupted...

could be either too much fuel or not enough fuel when going into vtec. try inceaseing and decresing by 15-20% and see if it crosses over ..
