[ej205 trigger 1 error]

Hello, ive been on a link ecu for many years without this specific problem, but I have recently been experiencing a trigger 1 error at about 6600 rpms with rev limit set to 7300.

So I do have can enabled, do you know if the gaugeart can gauge works with this ecu?

[G4 Wrxlink 7-9 digital display questions]

I have a link g4 wrxlink v7-9 and I am looking for a digital display of some sort, there are some can gauges that say they work for the old g4 models that have CAN, the board has CAN sockets but does this ecu support CAN comms?

[WrxLink Open loop boost control]

Currently wondering if I am fighting what I believe to be an issue, that may just be physics.

Used open loop boost control to have the car making 20.5psi tapering to about 15 at redline. In the mornings when it is about 55-65F ambient I see 20-21 psi consistently. Later during the day when ambient temperatures rise to 75-85 I see a boost pressure drop of 3-4 psi, a max boost level of 16-18psi. I know that this can be made up for using the IAT compensation but I am unsure if this is just a natural effect of air density, or if something is actually wrong. Thank you!
