ESS G3 idle issues

Where is the BOV and pressure regulator getting their vacuum/boost source from? Remove the engine cover and take a closer pic of the engine and all of the plumbing

What injectors are you running?

id1050xdc or whatever the newest one from them is i think its xdc but not too sure

It isn't the E85, I've seen people have issues like this with certain tuners, to only get a new tune from somebody else and the issue be resolved, which is why I asked. Maybe it is mechanical though, keep us updated.

I will keep yall updated. i dont like releasing tuner information just because i dont like people to potentially bash the tuner if its something they have disagreements on. nothing against any of you guys just dont want to release that information

i will definitely do that! i do remember some tubes around the tb were completely open and not capped off or anything. i dont know if thats concerning or not but i will take the engine cover off and get you guys a proper picture

UPDATE: tuner sees from his end of things nothing wrong as far as anything imrc or vct related. added a test tune to check some things. will update more once im back home

What you don't want, is for your tuner to be "tuning around" a problem, like a vacuum leak.

i definitely get that. will let you know how it goes

when successful will raise up to 1k rpm and never go down though untill i drive for about a quarter mile then idle will go down to the normal.

So my ESS is not as complex a setup as yours. However I've definitely encountered several of the exact things you're saying

#1 On initial idle the rpm sits at 1k and stays there till going into gear. Then behaves normal: This had sent me down a rabbit whole chasing vacuum leaks that didn't exist etc. Over time the idle returned to normal. But it took awhile.(Like way to long)

#2 The bounding RPMs: mine has never died as a result, but it certainly felt close. This usually worked it's self out after a few good drives.

Anytime I needed to reset or re-flash it would start all over. So I just chalked it up to the car figuring s*** out lol.

For whatever reason anytime I ran vented catch can with gutted PCV system and boost reference to manifold. Zero issues with idle. No fking idea why

I think it has to do with ESS telling people to used a shared vacuum/boost source, that also ties to the brake booster. This is a no no in my book.

What is a good location , besides the one ESS states to use ? I am asking since I will be installing my kit within the next few months and would like to avoid using a shared source . This would be on a Gen 3 car. Thanks !

Ideally, you want a vacuum block that ties directly to the intake manifold. This allows for each device (BOV, Fuel pressure regulator if using a return system, boost gauge) to have dedicated sources that do not share, and do not interfere with the booster or EVAP stuff.

The only way to achieve this is by using a vented catch can, which frees up the 5/8" port behind the throttle body. To me, this is a no brainer because I don't want any blowby or PCV schmeg going back into my engine, but some people prefer to maintain the PCV system, or a catch can that intercepts the lines, but still connects to the intake manifold.

Some cars seem to have a capped port behind the throttle body as well, so check first before you order anything

Going to directly off the manifold for reference definitely cleared up some annoyances in idle. No to mention the dedicated refrance made the reaction tiny a bit more snappy.

as promised, toon the cover over and got as much detail as i could off the pictures. please let me know if you see anything off.

thank you guys

2020 GT ESS G3 car with e85 and triple pump fuel system. We are having some idle issues. Just trying to see if anybody has came across this before. First off, i did not install this kit so please be patient with me as i may or may not know where everything is located in the car.

cold starts on the car are fine and the rom does drop down to normal temp. However, if the ac is on it can SOMETIMES have bouncing idle and can stall out sometimes especially if you put it in gear (a10 car).

warm starts are hit and miss. if i remote start it or even just get in and start it, the rpms are very low around 400-450 and itll either catch itself and raise itself up OR itll stall out again. i have higher chances of getting a good warm start if i let the car sit in the "on" position for about 15 seconds and itll usually start just fine. warm starts when successful will raise up to 1k rpm and never go down though untill i drive for about a quarter mile then idle will go down to the normal.

is there something im missing or something i can try out? had my tuner give me a revision and it fixes it mostly but the car just doesnt feel the same drivability and performance wise. i feel like hes working around and issue so i figured id jump on here to see if any of you guys would know.

thank you as always

Is your air intact sensor installed backwards?

are you talking about the maf sensor?
