I just finished building my first MS. All functions check out on the stimulator. This car has had MS installed, but it was built for me the first time.

I am having an issue that I think is map sensor related and I am wondering if anyone has some insight as to were i should look for the problem.

I am using the onboard 3-bar map sensor with the bulkhead fitting on the M.S. case (model 6300?). I have the correct values in megatune for the corrrection factors (28%).

Whenever I go into boost, my afr goes waaaay lean -like its almost hitting a brick wall -the ego tries to compensate, but it can't add enough. Basically i can boost to 0-1psi safely.

In MSlvv, The output graph shows that is getting datalogged values of 100-125+kpa -so I know it sees the higher pressure, but what gives? I thought I sent everything over from the last MS install.

Also, what mods do you do to the ini files for the usb adaptor?
