Default Ebc Attempting To Run More Boost

Okay Heres The Thing Before Ms I Had A Manual Boost Controller Set At 5psi Now That I Have Ms And Can Fine Tune The Afr I Want To Run About 6.5psi Well The Kpa Targets I Have Set Pretty High Like
Starting At 100 Then To 60 At About 3000 Rpm Well If I Change That It Doesnt Affect The Boost If I Turn Them All Up To 100 I Still Get 5psi???? Do I Need To Tighten The Wastegate Up???? ALSO MY AUTO TUNE MIGHT NOT BE WORKING RIGHT? WHEN I TURN IT ON IT SAYS CONNECTED TO CONTROLLER AND THE GREEN AND RED TARGET THINGS MOVE AROUND THE GRID AND SOMETIMES IT SAYS AUTO CORRECTION-0% IT NEVER GOES TO ANYTHING ELSE EXCEPT TARGET OUT OF RANGE??? DOES THAT MEAN ITS NOT WORKING?? OHH YEA AND ALSO DO I WANT MS TO MAKE O2 CORRECTIONS WHILE IN BOOST? IF SO OR NOT HOW DO I CHANGE TO FIX?

ok, 100 kpa is atmosphere, 0psi. 6.5 psi would be about 145 KPA. So set it for 145 kpa and see where that takes you. Also, take off your manuel boost controller if its still on there.

the solenoid is connected to a 12v source and then back to the MS to the wire I told you (blue/wht I think)?

you hooked it up correctly to the wastegate line? from source into solenoid on the single port side, exit through the side with the filter, into the wastgate.




try these targets;;; turn your overboost protection on to 8psi or something. if you hit a rev limiter when you give it gas it's working.



double check you burned js2 to boost control.

your car doesn't have a variable TPS. its off or its on. read this page and the link cited https://www.miataturbo.net/forum/showthread.php?t=11199

it's all i needed to figure out my EBC this weekend

his car is neither on or off, his MS doesn't see the TPS signal at all.

turboblue, the solenoid is hooked up correctly? JS2 is set for boost control under outputs?

js2 is the location on the mother board where the input is.

leave the TPS% as I posted.

the only thing I can think is the connection is somehow messed up. which 12v source did you use? how did you install the solenoid.

can you tap the ground wire to the frame and make sure the valve clicks/closes.
