Rev limit when vtec pops
Lsvtec turbo da pulls all the way threw when vtec is not engaged but once vtec is engaged it hit some sort of rev limiter/breakup. Vtec is set at 5500 rpm
Re: Rev limit when vtec pops
More than likely your grounds in the engine bay are not correct and it is grounding through the VTEC solenoid. Pay special attention to the thermostat housing ground.

Re: Rev limit when vtec pops
Am running a skunk2 4 bar map sensor but for some reason will not pop vtec with it installed.
Re: Rev limit when vtec pops
Post the calibration and a datalog showing the issue.
Re: Rev limit when vtec pops
There are no rev limits, boost cuts, or ignition cuts in the datalog. There is some other cause other than the ECU.
Are you using resistor or non-resistor type spark plugs?

Re: Rev limit when vtec pops
If it was something mechanical why would it work with the stock map sensor ?
Re: Rev limit when vtec pops
Those are non-resistor plugs and should not be used. You must use Resistor type plugs.

Re: Rev limit when vtec pops
Still doesn’t make sense why everything works with stock map sensor ? I would think if it was a spark plug issue it would do it regardless of what map sensor I use.
