Im having issues of my CRV not able to Rev over 2500 RPM. I have disable the spool but still not able to go over 2500 rpm. I have an AEM X series Wideband installed using D10 with R136 and R138 removed.

im looking at your calibration now. does it act like its hitting rev limit? you have any datalog files? i was running into a rpm wall but it was because of my boost cut safety.. can you slowly rev past 2500?

It feels like it hits the rev limit. Light or full throttle it will hit 2500 RPMS and bounce off that. The base map came from HAMotorsports and it worked prior of me installing the Wideband and removing the resistors. Once in a while i can get it to run properly with the laptop connected to the ecu. I have tried up loading the calibration with just the ignition on and still have the 2500 rpm rev limit. ECT is at around 190-195 degrees F. IAT is around 70 Degrees with 40 degree outside air temperature.

I have tried using new parameters and have uploaded it. The new paramters work when the Lap top is still plugged in yet once i unplug it it wont hold the parameters. I have noticed that once the lap top is unplug, the CRV will go extremely lean on idle.

What are you clicking on to upload the calibration to the ECU?

I have noticed that my car will occasionally bug out when uploading a tune. This can be frustrating when in the staging lanes at the track, but here's the best solution I've found to correct the issue.
Start with the USB cable unplugged from the laptop.
Turn the ignition to the on position.
Plug the USB cable into the laptop.
Click the lightning bolt icon in SManager to connect the laptop to the ECU.
Upload the tune by clicking the up arrow.
Crank the car.
If you have to turn the car off that is fine to do with the laptop connected, but you must disconnect the USB cable before re-cranking the car, or else the tune on the ECU may become corrupted. It doesn't corrupt the tune every time if I leave the laptop connected, but it does it enough to be a nuisance.
