Throttle Body upgrades?

[sonic_braaappp]

yeah, that re-assured feeling of being able to know right away if somethings not right

3 UG's for 3 cars or just one for 3 cars. Anyways I probably should have bought one before I started on the sonic. Would've helped a lot for my troublesome lean code before I replaced the manifold gasket.

yeah i agree, in my cobalt i had an aerforce interceptor OBD2 scan gauge (in the left pod) that read everything the ultra gauge does, but it could only display 2 parameters at a time. im definitely gonna get an ultragauge though cuz that was my favorite mod in the cobalt that wasn't a power adder

Clearly I have no clue of the benefit of the UG. Edify me please. Still on the fence about trifecta since I can't just swap back to stock on the fly like a bullydog or the like. How will the UG help me?

 

[krakenredbeard]

With trifecta you can swap on the fly via select a tune or swap entirely back to stock with a laptop bullydog is no difference sept it acts as the laptop instead of a actual laptop.

As far as a ug goes it just displays lots of different info via the odb2 port.

Thank you sir

well im IPF tuned and have had my TB ported and ported IM for the past year the increase in throttle response is very good ill be porting the intake manifold again since the dealer swapped it last visit.

FYI im looking for a stock TB I see them on ebay fairly cheap but the last few ive seen had bad cases. the case is not an issue when it comes to ported the unit the gen5 is the same way

So can you give is the info on how to remove the sensor on the side to be able to press out the pin so the butterfly can be removed?

Porting wasn't done by me. Was done by my coworker and you mean the case that covers the DBW? As soon as I get another I'll take pictures

What would happen if we replaced the electronic tb and pedal with a cable driven one? Would the ecu shut down the rest of the engine.

Yes. Considering when you press the "gas" pedal you are not actually controlling the throttle plate. You are telling the ECU that you want to move. The ECU then tells the injectors and throttle and ignition to dance according to the song you are asking to hear.

If you were to just manually operate the throttle blade, even if you managed to keep the TPS in tact, the ECU will go nuts trying to figure out how to balance the fuel with the amount of air you are allowing in.

I doubt it would run at all. Gone are the days where the owner has much control over throttle signal by mechanical means. It's all 1' and 0's at this point.

I figured, I don't mind it controlling other things but I'd like to control my gas pedal/tb I was hoping there would be a censor further Down the line to control those other things.

Well, there are tables in the tune that affect percentage of throttle in relation to pedal position. The stock tune does not have that as a linear function, believe it or not.

The Trifecta tunes (as well as other tuning options can) return that function to a linear relation.i.e. push the pedal down 1/3rd of the way, get 33% throttle demand.

That's the best we're gonna get.

I will be testing a ported TB later this month for the 1.4 and it will be ported by one of the best in the LSX world. I located A stock TB from a member and will be getting it soon so dyno results will follow with it and the IPF tuning software dyno should be finished next week

 

[SuperSonicRS]

Couldn't an adaptor plate be made to accept a larger tb, kind of like a tb spacer. This is assuming we could control the new tb via the computers/tuning.

Only problem I can think of is, would it even be beneficial to have more airflow at the tb only to be restricted back to factory at the manifold.

The ultimate solution I believe would be a larger more free flowing ss manifold fabbed up to accept a larger tb out of the box. An all-in-one unit

I mentioned this before. If the tb does return results they won't be huge I think. But if he's willing to play and get a dyno I guess we will find out.

On our 1.4, I just dont see a ported or larger tb having that much of an impact until we start getting much larger turbos that flow more air. On a n/a engine it makes a difference as the opening is larger therefore additional airflow can be introduced. With a turbo engine, the turbo is forcing air in va n/a where engine vacuum pulls it in.

But, please prove me wrong and I'll happily buy one/upgrade!

 

[MPFab]

Ported stock TBs on Evos make quite a difference. 60mm stk/65mm ported.

 

[Sneakerfix]

Here is the tear down of the TB it's pretty much the same as the LLT but the cover is glued on

 

[krakenredbeard]

With the cover off the pin can be pushed out correct? How did you go about getting that cover off?
