Vtec activation problem

[theo57]

Hello hondata

Sorry in advance for my bad english i am french :)

I have a civic Fn2 with k20z4, flashpro,RH,catback cai etc etc

I have a problem with my vtec since 2/3 weekend,maybe after modification on my calibration or upload calibration i dont know really.

I turn on engine (cold start) ,warm up,drive and vtec no engage!

I turn off engine,turn on directly and now vtec work

Its the same problem for each cold start.

Do you have already a same problem?

Thank you

Can you post your calibration and datalogs showing it not working when it should be and then a datalog after resetting the ignition.

Also from Help, About, what is the version of software that you are using?

Do you have a calibration before you made changes that does work?

[theo57]

Ohh no i don t know at what moment the bug come

I realise test when the weather is good with my other calibration

In last week i try to change RPM vtec, température activation,km/h activation,disabled engine oil level,create new calibration and include my all parameters,no result

Oil level and pressure are good,its strange when i turn off,turn on, vtec work good no??

Are you using live tuning?

[theo57]

Hello, no i don t use live tuning for the moment

Does the problem persist if you go to new calibration and start with a new calibration?

[theo57]

Hello,today i download the new version of firmware and the flashpro will not upgraded corretly 😒

It stays with the flashing power LED
