tested tps, map, main relay, all fuses. distributor, wires, plugs are good.. fuel pump is ok. took it for a test drive and at 5375 rpm it cuts off. looked at the logs and the sensors said boost cut, fuel cut and ign cut with only 5 psi. never even got to vtec. My boost cut is set at 26psi.

when i unplugged the vtec solenoid, took it for a test run and it went fine. checked oil pressure going to the vtec solenoid, and its fine. Changed the Solenoid and oil pressure switch.. The screens are clean...Wiring to the ecu is correct with no burnt wires.
I also tried a hondata 4bar map sensor...

last time at the track the car was cutting out, but when power shifting, it goes well. when returning back on the return lanes I opened up 2nd gear and the just cuts at vtec

so basically its hitting a boost, fuel , and ign cut right before vtec


any help will be greatly appreciated...

thanks for reading

 

there's no way we can help with this kind of problem without seeing a calibration and datalog file.

 

Is the any cel?

 

It's interesting that it doesn't do it with the HIGH cam turned off.

I had a similar issue when I took my car to Evans Tuning. It would CEL for boost cut at 5-6 psi even tho the cut was set at 15 psi. It happened driving up to the shop but stopped after a new calibration was uploaded. The session was completed without a hitch. Jeff said he had seen it before with similar remedy.

If the mechanical parts check out and it still doesn't make any sense, the software may be the problem. It can't hurt to try.
