- In this video I show you how to use hp tuners to convert to a 2 bar sd OS. The same principles can be used to convert to a 3 bar OS as well. I'll also be going over the differences between the P01 (0411) pcm and the P59 pcm.

How can i tell if i have the 411ecm in the holden mate...it has red and blue plugs and its a 02 but built in 01 vx commodore ls1 etc.
Here in the US, if it has the red/blue connectors it is a P01 pcm(0411) but I honestly know nothing about the Holden variety. Im assuming it would be similar though. If you open it up in HP Tuners and click on the "calibration details" icon, it will tell you if its a P01, P59,E38,etc. It will be listed on the far right of the same line where it states the year and model.
Bad Luck Garage thankyou.
No problem brother. I help where I can. Unfortunately Aussie vehicles are a bit beyond my level of expertise,lol.
A couple things to add to the video for other new people, just some general setup tips.
After going to a 2 or 3 BAR OS, the OS normally will automatically put in 2 or 3 BAR linear and offset settings for the MAP sensors. Make sure that whatever MAP sensor you purchased matches the settings. Most GM 2 bar MAP use different linear and offset settings than just is given, 3 bar stuff is can be several different values depending on what vendor you bought the sensor from. Having this info correct is a 100% must.
Also if you are going to be running in speed density only without the MAF sensor you will need to fail the MAF sensor within the tune file still. Easiest way on a P01 or P59 is to set the MAF fail high under the engine diag tab to 0hz, then set the MAF dtc's to MIL on first error. That will revert straight to SD at start up. I also change the dynamic high rpm disable from 4,000 to 8,000rpm as well. Don't forget to wire in a separate IAT sensor if removing the MAF housing, can't tune a vehicle that says it has -38 intake temps all the time.
Hello GTPSilvermist, Thanks for watching!This video is dealing with the OS conversion itself. I'll be making more tuning videos dealing with specifics soon. Be sure to subscribe for notifications!
Yeah no problem, I gotcha. Good video showing to go about it. I was just browsing the tube and like to see how others do things. Video or picture tutorials sure help for some over me or you just typing what to do lol.
Most of the instructional type videos I make are exactly for that reason.....to cover questions that get asked constantly and i get tired of typing pages of explanations so I just make a video instead,lol.
There needs to be a like x10 on this video, learned so much, been watching all your stuff, Thanks for the effort to share...
Thank YOU for watching Doug! I’m glad some of the videos are helping you brother!
Awesome! I have been requesting someone to make a video like this for the newbies... Thanks much Boss!
Glad you found it helpful brother. 👍
Best video I've seen on this by far. Thanks for the info!
Thank you sir. And thanks for watching! Be sure to share if you know others that could use the info. 👍🏻
Thank you ...... so frigging much .... literally everything I couldn't wrap my head around in one video
Thanks for watching brother. I’m glad it helped you out! Please be sure to share if you find anyone else that this video could help out!

extremely helpful video, i am now subscribed
Hello chris brehaut, Thanks for watching and for subscribing! Glad this video helped you out! If you know someone else who may be interested please feel free to share!
Thanks for the video, cleared up a few questions I had.
Glad it was helpful brother.
Going to do this on my boosted 08 vette in a min, i want to KEEP the MAF. Do i need to do anything special? Or is it still in play after the OS change. Mahalo, im now a subscriber.
Do you have an explanation on how to do this on a gen 4 pcm. I just put together a turbo kit for my 07 avalanche and I'm gonna need to tune it for boost. I've never tuned a injected engine before and in trying to absorb ask the info I can before I start. Thanks in advance.
That's a good video for that. I was trying to convert my friends camaro to 2 bar (0411). We got it running but it wouldn't log the map in the data log. Can you cover this?
Thanks for watching Brent. If you’re using vcm scanner 2.24, you should be able to delete the old 1bar pids and select the proper pids and histograms once you connect to the pcm with the new OS. If you are using vcm scanner 3.x I’m afraid I can’t help yet as I haven’t taken the time to figure it out myself. After dealing with multiple problems with version 3.6 while trying to tune a customers vehicle, I decided to just use 3.6 editor with 2.24 scanner. That was several months ago and I’m still not using it. (Don’t really have a need to). That’s actually the whole reason I made the video on installing multiple versions of hp tuners in the same computer. 😉
I know this is an older video, but do you know if the injector data stops at 1 bar or does this update those tables too?
I’m having troubles on my spark tables, when I plug the vcm scanner and my spark advance table populated with cells, what do I do? Do I subtract those from the current ignition table or is there a certain range that the cell table is supposed to be at and you want to add or subtract whatever to get there
Hello Tanner Reed, Thanks for watching! I would start off by pulling timing in all areas where boost is seen. To make things faster and easier, I suggest starting with a file from a similar boosted setup and copying the timing maps over as a starting point as mentioned in the video. Then log KR and go from there. If you want to start from scratch, Factory timing maps are usually very conservative so just make sure nothing is above about 12 or 14 degrees on the bottom half and start working from there. As I mentioned though, its usually less time consuming to just start off with a file from a similar build. Hope that helps. -Robert
To get these options in the "OS" , do you have to have the User Define Parameters option purchased from hp tuners?
No, you do exactly as shown in the video.
What if it's blank when you click the OS tab? The computer I have doesn't have nearly the options! It's also not running an LS engine but...

This is my first turbo build. I have gotten a pcm from a friend that had a 3bar tune on it.If I'm just running 12 lb of boost would that pcm run ok with a 2 bar map?
No. You need to either flash it to a 2 bar os as shown in the video, or use a 3 bar map sensor to match the 3 bar os.
i did my 3 bar os conversion and installed a 3 bar sensor. at idle its very rich (11.80ish) i tried a few things to try to lean it out but nothing worked yet. are there any changes i should be making after the os change to correct fueling thanks
Hello chris brehaut, Thanks for watching! Copying the tables over will only get you started. You will still need to tune the VE table after the conversion to dial everything in.
oh ok i will have to read more and learn haha thanks for the videos
Yes sir! I plan to do more tuning videos at some point so be sure to subscribe so you'll know when I do. And thanks again for watching!
I have a question about RTT(real time tuning). If I previously flashed my ecm from stock to RTT using a custom OS. Is it possible to re flash back to my original stock tune and then flash again to a two bar custom OS?
Thanks
Yes as long as you saved your original tune file.
Awesome, how you been? I hope all is well with you!
@@CorEdmonds I’m doing ok brother. Thanks for asking. Still not 100% but I’m alive so there’s that. Lol.
I notice the spark tablenis still in mas air flow do you still need to keep the maf sensor connected?
The spark tables are not scaled by Mass air flow, they are scaled by cylinder air mass.
And no, you do not need your MAF sensor unless your IAT sensor is incorporated into it, in which case I highly suggest pulling the two wires for the IAT circuit and switching to a segregated IAT sensor. I’ve covered that in other videos.
Thanks man that makes sense yea ill ditch thw maf and add the gm iat sensor. Cheers
No problem brother. Good luck to you!
Why 25% more when you filled from 1 bar to 2 bar. Wouldn't double the atmosphere require close to double the fuel? Therefore 100% more as opposed to 25% ?
No. Although this table is used to modify fueling, it isn’t an actual fuel table. It’s a Volumetric efficiency table. The numbers represent a change involumetric efficiency which tells the pcm to deliver enough fuel to compensate for that change. You’re not “adding 25% of fuel”, you’re showing an increase of volumetric efficiency. And as stated in the video, adding 25% here will actually have you running pretty rich initially in most cases to keep you safe while you’re actually dialing it in with a wideband. Hope that makes since.
Bad Luck Garage got it.. thank you
yes sir! Thanks for watching and dont forget to like, share, and subscribe!👍
How do I get you to help me tune my truck? I have a 2003 gmc sierra I took the 4.8 out and put in a blueprint 427 complete engine. The engine was dynoed before I received it. I'm in southern Kentucky. I don't have anyone close to me to help.
Hey brother I’m sorry to say I don’t do 3rd party tunes anymore. I was planning to make more of these videos to help people who are trying to learn to tune for themselves but I don’t use the most current version so there will still be some slight differences if you’re just now buying a newer unit with the newer software. I would encourage you to get in the Bad Luck Garage Facebook page in the files section and download the CPIG guide. It will guide you step by step learning the basics. I actually uploaded it there because I get so many emails and requests like this. Learning to properly tune a vehicle takes lots of research and lots on hands on trial and error. It’s not just a “one day course and you’re done” type of thing. Hell I’ve been doing it a few years now and I’m still a novice myself.
@@BadLuckGarage I have the newest hp tuner. And have messed around with it a little. Is there any decent places in Knoxville that could tune it? I'd like to at least get it to move in and out of the garage for now.
We have Lethal Performance in Morristown, and High Velocity in Knoxville. Both are fairly popular but both are about 50/50 on reviews. I’ve never been on a dyno and always done my own so can’t really testify to how good they are but I do know Tony at High Velocity has always seemed to be a standup guy and is actually at the track that sponsers my channel working in customer cars on the weekends sometimes. My suggestion is to download the CPIG guide as I said earlier. It’s a step by step repeatable “basic tuning” guide and if you follow it you should easily be able to get your car driving pretty good. It won’t be making the most possible power but if you follow the guide it will definitely be drivable. Even if you don’t have a wideband you can use your fuel trims to dial in your part throttle and cruise area under 3000 rpms really accurately. Hell I may even do a video on that in the next few days since I just did it in the DRNova last week and people keep asking. Lol Also all my config tiles I use to tune are also in the files section of the Facebook page for free download along with that CPIG tuning guide.
@@BadLuckGarage ok I'll look it up and down load. Thanks
Yea sir. Like I said. Lots of research and trial and error. I bet I spent 100s of hours online just learning to tune my first engine and it was basically stock! Gotta have patience brother. Most people can’t just dive in and be like “oh yea I got this” lol. I was definitely not one of those people!
Can you use this to tune without boost ? My idle problems are freakin changing every drive. Perfect sometimes stall sometimes in traffic at every light or stop sign 🤬🤬🤬🤬
There’s no reason to convert to a 2 bar OS if you’re only running a 1 bar map sensor.
Bad Luck Garage ok. If I didn’t have to stop I would have a bad azz 84 c10 with a LS 5.3 🤠
Have you added a cam? Because it almost sounds like you may need to ad some to the idle airflow tables.
Bad Luck Garage I added a 598/601 Howard cam headers CAI bored it .30 mm everything else is stock turbo 400 I can do the engine controls in scanner and make it idle great by lowering timing and adding like 15.0 on air/fuel button but when I cut it off hot it will rev to like 3000 for 3-6 seconds lowering timing and playing with idle steps in control mode doesn’t help that high rev part.
Sounds like you just need a tune brother. You can’t throw a cam that large in without having it tuned.
when i click on os nothing comes up is that becuase i cant run that?
Thanks for watching! There are supposedly some OSs that don’t support this but the majority of the time if you get no upgrade options, it’s because there is already a custom OS on the PCM. It’s possible the previous owner has already flashed a different OS on yours. If that’s the case, the only way to change it is going to be to do a full rewrite with a factory OS, then you should have the option of picking a custom OS to write.
Bad Luck Garage i actually put it in advance mode and that fix it. I thought i was going have to do a full rewrite
I’m always in advanced so sometimes I forget there are other options. Can’t do much of anything in basic. Glad you got it figured out. 😉
