boost control solenoid - ohms?

[LowLife]

Does anyone know what the ohms reading should be for this? I'm getting 25.5 ohms and I'm not sure if that is good or not. It's getting 11.6 volts coming into the harness. My boost is stuck at 10psi.

Can someone give me a reading from a known good boost control solenoid? Thanks!

When you say stuck at 10psi, what does that mean? Do you mean the gauge is stuck? Or do you mean that it won't make more than 10 PSI? If you provide more info, we may be able to help more. I am unable to answer your question about OHMs but I think some more info may lead us in the right direction.

It won't make more than 10psi....ATR Pitbull chip should be making around 18 I think. Pulls strong to 10psi and then it feels like it's cutting out and that something is "holding it back".

I also get a strange "ticking" noise when I'm building boost....almost sounds like an electronic "tick, tick, tick" coming from under the hood. I think this solenoid may be blown or not working correctly. It sounds the way a relay would sound if it were bad.

Hopefully that's enough info! Hopefully I can get an ohm reading from someone. Thanks!

Re: boost control solenoid - ohms?

It looks like EVO guys use this same part number we use and they are saying it should be 24 ohms based on google search. I would think 24ohm and the 25.5ohm that I am getting are close enough to rule out the boost control solenoid. Thoughts?

What else would keep me in safety boost (base boost)?

Not sure it that statement is correct? Street or race chip w/a 2 bar map sensor?

Maybe it's detonating,(the electronic tic,tic,tic) so bad it wont make boost?

Drain the tank & use race fuel,C-16,see if it will boost more than 10.

Scan tool,got one?

Re: boost control solenoid - ohms?

We only have 93 octane here in GA....I might can make the 45 minute drive to the track to get some race gas though if needed. It's the street chip w/stock injectors (SY137A).

Not sure what map sensor is in there?? How can I check that?

Ordering DataMaster next week.

Re: boost control solenoid - ohms?

Can you move the wastegate rod in and out with some effort? It should move a fair amount. Are your vaccum lines good? Are you reading this boost reference from a good gauge or the stocker? Unless you have converted to 3 bar MAP, then 14 PSI is about all your gonna get. Most of the off the shelf chips (except for STG) were meant for factory MAP as far as I know. The ticking noise you hear could be a number of things. Exhaust leaks are pretty common. What else is done to the truck?

An ATR Pitbull use open loop boost control. You adjust the boost level by adjusting length of the wastegate rod.

Re: boost control solenoid - ohms?

Just woke up, so I'll try and provide some answers.....

1. I have not tried moving the wastegate arm yet. I didn't realize the ATR Pitbull chip worked based on the wastegate arm. I will try this when I get home today. Should I move it in or out to attain more boost?

2. I am reading boost levels from an AutoMeter aftermarket gauge, not the stocker. The ticking only occurs under full acceleration when boost is trying to build up. Normal driving, the ticking is not there.

3. DaveP - I am not getting any lights on the dash....but, I will try that relay.

Thanks for everyone's help!

You can hear ticking while WOT? Are you sure it's not detonation? Are you using a scan tool to monitor knock?

How would I have knock with 93 octane? Do I need to check knock sensor? Maybe it's faulty?

Re: boost control solenoid - ohms?

You can be getting knock at any time. Doesn't matter what gas or what chip. Knock can be caused by a number of different issues, chip, fueling,airflow, engine falling out. Get data master before you drive this truck again.

Re: boost control solenoid - ohms?

Did a little investigating tonight.....

The Ty is running an ATR Pitbull chip and a 3-bar map sensor. Is this an issue? My AutoMeter gauge is reading 10psi. I'm ordering the DataMaster in the morning.

Re: boost control solenoid - ohms?

Its not an issue if the truck is running correctly. Datamaster will be able to show how the truck is running.

Re: boost control solenoid - ohms?

ATR never made a chip for a 3 bar MAP sensor, so yes its a problem.

Re: boost control solenoid - ohms?

Would it cause the truck to run the way I described above? Would switching to a 2-bar map sensor make the truck run better?

I know DataMaster will steer me in the right direction.......but inquiring minds want to know!

Switching to a 2 bar should make a huge difference, and yes it could be causing the above mentioned problems. Now if you have other problems they will need to be addressed obviously. Are you sure you have a 3 bar in currently? Did you check the numbers on it to verify?

Re: boost control solenoid - ohms?

Yes...mine has part number 12223861 on it. I will purchase a 2-bar map sensor and see where that gets me! Thanks!

Nobody made a chip for 3bar before 1996 or so. Every one of them out there evolves from code that first appeared in the original ultimate.

Somewhere along the line, people got it into their head that the "3 Bar MAP sensor" was the magic, but it does no good whatsoever without the proper programming to go along with it. The ECM has to know that a 3 Bar sensor is there.
