I never mess with the custom OS mods but it doesn't seem like you can switch one back after you apply it. You would have to go back to a version that hasn't been converted and start there. I assuming you want to change it from the 2-bar to the 1 bar speed density enhanced.
All he has to do is write-entire the one I posted. The going back to unconverted is for applying a different OS tune-side. The ECU doesn't care.
When I clicked toe speed density one they both disappeared and wasn?t able to do anything else
Once you click it coverts the OS. If you go into the info tab you'll see new OS. You save it to a new file name and write entire.Originally Posted by smasher
Or you can use the one Sirius made
Yea I got that. But I’m just trying to figure out what is going on with it. Let’s say I add a 2 or 3 bar sensor is it gonna pop up and ask me if I want to add it?
Are you planning to boost it? You'd have to convert one of your HPT files that isn't already on a modified OS. You could run on a 2bar right now, if you configure the MAP settings but you can only see/configure 1bar in the tables. If you boost it you'd convert over to the 2bar OS so you get extra rows (in boost). No reason to run 2bar if you aren't going to boost it.
No, the software does not detect a MAPS change. You have to manually enter the linear and offset when you change the MAPS.
I do have a d1sc Pro charger sitting on the ground right now that I'm piecing together, but I want to make sure everything is right before I put it on. I believe the 2 bar is good till 14 psi if I'm not mistaken. My goals are 1000hp at the fly wheel the motor has forged internals, and I want to stay on pump gas rather that be e85 or 93 doesn't matter. Id imagine I would be pretty close to that goal at around 14 psi.

It'd be a good idea to get the ks problem fixed.
Gonna need bigger injectors for 14psi. 6psi maybe.
Recommend a TMAP for boost.

will that map sensor fit and plug in or would I need an adapter for it?

Fits perfectly. Need to wire up the pigtail under the Associated Parts tab.
Well. It does on the LS intake. What intake do you have?

tbss but im using the same connector and map sensor from the ls truck intake

There are adapters, but they'll throw the IAT reading off. The purpose of the TMAP is to get an IAT reading that's close to what's entering the cylinder. You can also go the separate IAT route and put it in the intake manifold or pipe.
Right now the IAT is in the MAF. The complex temp model will be a constant pain with boost hardware.
so, with the Bosch one I would need to wire in the iat one or would the pigtail have everything I need?
If you boost it, you'll want the E85. You'll need a lot of fuel with e85 though. I am not sure you'll get there with a supercharger. Even with pump gas you'll need to upgrade the fuel system I assume. pump and lines, etc... Why wouldn't you look at a turbo?
Yep to this.
From my experience, I would not slow play this on the parts list. If you know your gonna boost it, get injectors big enough to handle what your after now along with the other supporting hardware. Your gonna need to be in the neighborhood of 100 to 120 lb/hr injectors if you want 1k hp at the crank on E85. I'm on E70 mostly, with ID1050x's and 15 psi of boost with a 6.3L LS1. I don't know how much power it makes but the injector duty cycle is 90 to 95%, at .79 lambda, around 6,500 rpm.
You can tune a N/A engine to run on too big of an injector. You won't be able to keep a boosted engine alive for long on too small of an injector.
For the TMAP the MAP and IAT are combined. With the MAP on there now a separate IAT would have to be put in the manifold.
Superchargers to me are simple and more reliable. No need to run oil lines to my oil pan
I believe I’ll have to upgrade the fuel pump as well currently running the Walbro 255. Probably gonna need at least a 340 or 2.
