Re: WGDC sometimes works...sometimes doesn't. HELP!!
Update - I have since opened up the factory ecu case and done a continuity test all the way to the plug at the ecu. Both 12v and ground show good continuity. I have cleaned the ecu pins along with the plugs for the ecu. This seems to have now solved the issue, although there was no visible corrosion...

Re: WGDC sometimes works...sometimes doesn't. HELP!!
Update - looks like I must have a faulty ECU. I’m getting continuity from the grounding pin of the solenoid all the way to the ECU plug, as well as constant 12v power at the plug.
Tested the solenoid again and it clicks like it’s supposed to.
Thats rather annoying :/

Re: WGDC sometimes works...sometimes doesn't. HELP!!
EBCS are just solenoids, so I don’t see how polarity would have any effect on operation. EBCS are electro-valves, they may have some coils inside so feeding them inverted current may drive them in the opposite way. I've never cut one open but the safest approach is to make sure they get the right k...

Re: WGDC sometimes works...sometimes doesn't. HELP!!
Well, if it wasn't for the last post I would have said that you have a too soft spring in the wastegate actuator or a cracked membrane. Assuming the harness is good there is no way either a Grimmspeed or a MAC valve (basically both are the same MAC valve) would throw this code. Maybe the EBCS conne...

Re: WGDC sometimes works...sometimes doesn't. HELP!!
Update: Car is throwing a P0245 wastegate A low code. Hadn’t thought to scan DTC’s previously as I got no CEL. My assumption would be this code was present with the Grimmspeed EBCS as well. Clearing the code doesn’t help and just pops back up upon starting the car. Getting 12v from the loom with ign...

WGDC sometimes works...sometimes doesn't. HELP!!
Very odd situation here - after calibrating MAF and setting up fuel and ignition tables, I've moved onto raising WGDC. Load target of 2.3 @ 5k rpm. Initially running a Grimmspeed ECBS hooked up in 3 port config. 100% duty did not raise boost pressure at all, stuck at 102-108kpa. Tested solenoid off ...

New to VT - I'd love some feedback!
Hi, I'm Jermaine. Not long got into a Gen 1 3 and have been loving it (oddly enough, my first fwd) The car I bought already had VT installed so I decided to get some data on the Dyno. Figures weren't as impressive as I had hoped. 295hp/334ftlbs @ the flywheel @ 19psi. Stock turbo. I have since upgra...
