    I just upgraded to v3full and would like to do boost by gear. I know they reccomend the ingersoll rand solenoid. Was curious if the aem tru boost solenoid would work? Cant find much info on it. Also do you think the truboost controller is better than doing the boost by gear in dsmlink?

    If you don't get an answer, might be better to post this on link forums.

    The driver in a 2g ECMLink ECU (I'm being specific because I've only looked at the 2g's chip spec sheetT) for the boost solenoid supports up to 2A of current, and that solenoid from google runs at a peak of .45A, so you should be fine current wise. The solenoid supports up to a 30hz duty cycle, but I think ECMLInk is limited to 16hz, so you won't have as great a control as you might with another controller.

    I appreciate the response but that is all Chinese to me. I am familiar with the AEM goes off of duty cycle and I assume dsmlink would be the same. Wouldnt the solenoid be what is physically controlling boost to raise, lower, and control creep/spike? I am not looking to buy a new controller but the dsmlink one is free since I have everything. If the AEM is better than ill just use that. I log ECUBoost and it matches my AEM, not sure if that has anything to do with our discussion. Your reply was totally something I wasn't expecting. HZ as in speed, 30hz refreshes faster than 16hz. So the controller could act quicker?

    Simple answer is the AEM solenoid will work the same as the Ingersoll. Should make no difference to Link.

    I have finally got around to doing my dsmlink boost control with the aem solinoid. I am having some issue and dont know if its solinoid related or setting related. My wastegate springs are 16psi springs. The reason is to have lower boost for first and second. But I am trying to set up 3rd gear with boost goal of 35psi. I have tested the solinoid and it clicks with power. I also confirmed that with pressure in it, then applying 12v the air moves ports. I have my wastegate lines ran correctly.

    My original issue is boost spiking to 38 and by the end of a pull it would go to 25ish. Now it settles around 28 at 7500. It seems like no matter where I put the duty cycle, it always falls off to 28. I attached the log. The first pull in the log, was with error correction enabled. The other pulls are with it disabled. Maybe I am reaching the limit of the dsmlink control or the solinoids control? I have read the wiki and as well as other posts on here.

    If your gate has a 16lb spring setup in it, then the most you can get out of it will be double the spring set, at the most, with a MBC or EBC.
    Have you tried a 100% duty cycle to see the max boost? I think you are at your max at 32ish, but someone correct me if I am wrong.
    Are you using the top port, bottom port or both on the wastegate?

    Man, you been on all my posts lately LOL.

    I have it routed like the image attached. I have tried 100 duty and it still bleeds to 28. I found a formula but I dont know if its accurate. Targetboost√∑wgspring=dutycycle. I have tried a variety of settings. To rule out if the aem solinoid is bad, I was going to try the stock bcs but then I was unsure about how to plumb the gates.

    I am a stalker............:sneaky:
    The diagram is spot on for boost control. I am having gate issues also is probably why I am following you around so much ROFL
    I have finally got so frustrated that I am running the gate without any boost reference source, gate stuffed full of springs and I can only get my lil HX40 to 33-35 lbs max. Wondering if I have any excessive exhaust back pressure so I am going to go straight open DP to test. Its that or I am at the compressors limit and I could run 44 lbs on my other HX40 with a 38mm Gate. I am having issues right now with my 44mm TIAL.
    I thought maybe my EBC solenoid wasn't doing its job but it oscillates on my logs but I could never get any MORE boost with it. If I ran my reference source to a bottom port, I could get it to LOWER but......:banghead:

    I have boost leak tested the crap out of my car. I was able to get a spike to 38psi. But I can hold 28psi during a pull. Seems like were in the same boat. I read all these posts about people running 30+ during a pull. What is your airflow lb/min at 30psi? I read that my 7blade is a +50lb/min all day. Yet I cant get there. I see 48lb/min. Let me know what happens with your downpipe test?

    To use the stock bcs, is that possible with when using the top ports on the gates?
