Hi guys Im having this weird boost cut out of nowhere , on vtec it doesnt do it, only on low cam. Ill attach map and log.

What version of software are you using from Help, About?

Latest. 2.3.7

The datalog you have uploaded does not appear to have been created with that version.

Well it was in fact created with this last version. Just instaled it in the morning and started mapping/logging with it.

If you open this datalog you will see that all values are flat lined and it is not showing proper data. It is also saying that it needs to convert the datalog because it was created using a previous version of software.

Dont make sense at all. Just instaled 2.3.7 on another desktop and opened the same file and datalog. Shows all the data. Can you please make sure or elaborate cause i can see al the data as we speak in this other computer. The car/ecu boost cuts only on low cam partial or full throttle at around 2-4 psi. On high cam no trouble at all.

Here´s another file and log on 2.3.7. Still acting...sometime boost cutting at 2-3 psi sometimes at 9. Again i see the log perfectly with all the data.

The boost cut seems related to 4500 rpm (VTEC point).
Can you test these things, one at a time:
- disabling launch control
- setting the rev limit type to fuel only
- changing the VTEC point from 4500 rpm to 5000 rpm to see if the cut changes as well
The check engine light shows as on the whole time too, which is not normal. If you datalog immediately after startup, is the check engine light on?

Found the issue , thanks. The car doesn't have its original gauges and someone did a wiring conversion from a civic mb6 to a eg. Checking the log over and over i found the MIL was on through the datalog as smanager wasn't throwing any error code. So found out that somewhere on the harness the service conector was grounded so just unplugged the pin for it on the ecu and the MIL went off as expected. That sorted the issue. Thanks for the help. A sugestion for S manager btw would be some sort of highlight for the MIL even when there isn't a error code present. Thanks again

Glad you got the problem fixed, thanks for the update.

Thank you for the help
