Hey guys so I'm looking for opinions on how I should proceed from anyone with experience with this. So to start I have a 2g eclipse with a 6-bolt swap. Currently being tuned, and were having a bit of an issue with the new ingersoll BCS. I cut the wires to the old BCS(old bcs was not plumbed) and wired in the Ingersoll. The single port side of the ingersoll is ran to the wastegate, the bottom of the dual port side is ran to the compressor housing of the turbo, top port vented. When trying to increase boost at 100% duty its not raising at all. I double checked the vacuum lines, confirmed I'm getting 12v power to the solenoid. I'm thinking there may be something wrong with the wastegate grounding wire that goes to the solenoid from pin 11. Note this car was swapped when I got it, so wiring was done by previous owner and I dont know what was touched that shouldn't have been.

So my question is, how should I proceed? Should I run a new wire from pin 11 on the 2g ecu, to the solenoid to ensure its getting good connection and still use the confirmed 12v wire? Or how would someone else tackle this kind of problem? Any help is very appreciated.
 
This is the diagram I went off of because I do still have an internally gated turbo

This is my latest log when we were trying to get the solenoid to respond, let me know if I need to log anything extra and after work I will get right to it!

I dont see anything too weird... either it gives power and ground or it doesnt...

you can test this pretty easily by setting it all to 100% and then seeing if the solenoid is open or closed (manually check - blow thru it). Then check at 0% and it should be the opposite.

Are you guessing that it is a wire issue? or have you done some probing with a meter?
 
I have done some probing and that’s my best guess at what it could be. It has power, I tried to test continuity from the other wire by using a chassis ground with one probe of a multimeter to that second wire with the other probe and nothing. Is there a better way to test it? The key was in acc when I did this
 
There is no reason to think that Pin 11 (Turbo Wastegate Solenoid) would need to be activated with the ignition in the "Accessory" position. Try your test again with the key in the "On" position.

..., confirmed I'm getting 12v power to the solenoid. I'm thinking there may be something wrong with the wastegate grounding wire that goes to the solenoid from pin 11.

Originally, you said you did get power. Has that changed? If you do confirm power from the ecu with the key "On", then yes, it probably is a bad ground.

You can also try connecting the bcs directly to a 12v power source and ground and listen for actuation.
 
There's a checkbox for actuating the BCS I think in the Misc tab, you should be able to verify it's at least getting a signal but checking that while listening for the BCS' "click" when it actuates.

I had issues myself trying to get ecmlink to control boost properly with that solenoid and ended up giving up on it entirely and using a Cortex EBC that still gave me rpm-based boost control. Will be interested to see if you get it working. I personally could get the solenoid to actuate with the aformentioned test, but I just couldn't get good boost control while driving. Though in my case I also tried a Borg Warner BCS and it too didn't work right directly connected to the ecu, so I'm not sure I had a BCS issue but rather something else.

I did say accessory didn’t I. I meant in the on position. So to correct myself, in the ON position I get 12v from 1 wire and nothing when testing the ground wire.

Thanks for the tip I will give that a try as well just to see if the solenoid is indeed actuating or not
 
When you turned the key on: Did you have the table set to 0 or 100% duty cycle? Did you check it in both conditions?

My guess is it pulses ground for PWM and if you demand a 0%DC, then you get no ground. Just a guess...

Try it both ways.

As for gear specific boost control, what kind of issues did you have? It took me some time to get realistic DC and boost targets, but once I did it works flawlessly.

I’m not sure off the top of my head I will double check after work and I did not try both conditions so I will do that as well. And the guy tuning my car was trying to get my boost to 20 I believe(tune in progress), but up to 100% duty it’s not increasing boost at all. That log above was a wot 3rd gear approximately 2300-6500 rpm pull. So he said that there is something wrong with either the solenoid itself or routing/wiring
 
I agree with him. This will tell you if it is wiring vs solenoid. If you get ground and it doesn't actuate, then it likely isn't a problem with the wiring. As mentioned by others, you can also just power the solenoid from any 12v source to see if it is actuating (but I recommend blowing thru it to be sure it is actually doing what it is supposed to)
 
Hey guys update on this, I figured out the internal wastegate of the turbo had no preload on it(completely forgot my tuning shop did this for break in so I didn't build boost), I set it at 3 full turns of preload, I did a couple light pulls afterwards and the BCS is working properly :aha::applause::hellyeah:
