3 bar MAP

[southtxSHO]

Same thing happened to me when I loaded my tune and 3 bar sensor . All I did to was turned it off , opened door , closed door back again and started up the engine and wrench light went away . This was on My Cal non touch

Wouldn't that be something....if all I had to do was shut it off, open and close the door, then restart. I'll have to wait till tomorrow to give that a try. All my free time is used up for the rest of the day

Hope it works for you . When I first started up the engine and saw the wrench light I was like Wtf ??? lol but after turning it off and other stuff it went away .

I'm getting pretty good at installing the sensor & tune throwing a code and going back to a 2 bar set up. Tried again this morning. Only adding the shut off, open door and restart. Made no difference. The only thing yet to try is to load the 91 3 bar. I haven't done that tune yet. I have exclusively loaded the 93 tune. One more thing to try....

I installed my 3 bar and ran it boost is dialed in a little higher judging by my torque app. I am having a slight hesitation when WOT from a stand still which I am sure a data log will fix but other than that the 2 bar to 3 bar conversion for me was night and day.

Forgive my ignorance on this. I saw a post on here a while back that explained but I cannot find it now. I would be installing an non PP '11 SHO. As of now, now immediate plans for downpipes. (California emissions), but I am halfway planning late this year or early next year to install performance exhaust. Probably use Corsa or have shop build custom setup.

But exactly what does the 3 bar map do?

Is it beneficial for those running without the downpipes and exhaust?

What gains would I see from it? If any?

And where and how to install?

Thanks for the help!

Your car comes stock with a 2bar map sensor on the top of the manifold.  The ECM can only read up to 14.7 psi of boost.  This is fine as long as you stay (in the tune) below that threshold.  If the car is boosting over 14.7 psi the computer does not know to add fuel and can create a lean condition (not enough fuel) = very bad.  If you want to make more boost than the 14.7 you need to upgrade to the 3bar map.  This allows the ECM to see 20 plus psi.  Some tuners recommend meth injection when going 3bar.  So the 3bar map itself does nothing to increase power.  The tune can then be set up above that threshold (via the 3bar) so then the computer can then add fuel and or timing etc for the appropriate boost level.  Making more boost and adding timing = more power.

So generically speaking then, and to try and quantify, by simply adding the 3 bar, a revised 91 stage 4+ tune would/could take my car to 450 hp?

I know these may be wild numbers, just trying to justify if a 3 bar by itself is worth the investment in and for my scenario. Then where would I purchase a 3 bar from? LMS?

I have no intention of adding meth, but a revised tune and better exhaust are in store. Just time and money to do it. I currently have LMS working on some upgrades/updates to my tune to address some shifting issues.

Sent you pm...

pm sent as well as another happy 3 bar map consumer

Thanks guys for explaining this to me. I will be ordering one soon. Just need to find and verify the right one. RED, is the link you sent the correct part? No info when I click on link.

As long as part number of the one you get ends in a "B" (including the number stamped on the sensor) your good to go.  If not, just send it back. 

 

[REDSHOCGO]

Yes that is the 3 bar link same part I ordered.
