Turbo BS Thread

Thanks for the info, yeah i have been adjusting everything so its no surprise the stock ecu is pissed off. I am decent at basic fueling, but trying to deal with the stock ecu at the same time is a little bit above my skillset currently if im honest

 

When im going in and adjusting the o2 adjust table, is that affecting the MAF voltage the ecu is seeing?

 

You might need to just clear out your OBD2 when it gets confusing.

o2 is it own thing and maf is it own thing. I keep my LT fuel trims at idle around -10%. Fuel trims gets closer to zero as I increase in load. Tuning the closed loop isn't easy.

Make a few small changes and look at your fuel trims once ST levels out. It took me a few weeks.
You shouldn't be using afr adjust until you are making positive pressure. I don't start until 0 psi.

 

Hey oh still scamming from the shadows. Yeah @BassAckwards it can be kindve of a bitch in the beginning, but itll get easier as you go. Fully understand stft, ltft, maf voltage, im probably forgetting something. @MadTaco461 and a couple other guy's helped me out tremendously.

 

Time to get this on and make the boosty noises!

 

Mike has been very helpful for me as well, this is just a little bit above my skillset im afraid. The truck is still my daily driver so i swapped back to stock injectors and my old tune this past weekend just so the stock ecu would quit bothering me everyday lol. I may take another look at this in the future but its on hold for the time being.

Looking forward to it! Were so close now

 

No video clips from the weekend. Sand was soft this year. Started overboosting yesterday. I have to figure out why my wastegate is staying shut next weekend.

 

I run 550cc injectors 2tr-fe with a 2tr-fe. I have a decent tune that works okay

 

Are you using the MAPECU3 for tuning?

 

It likes the colder weather?

 

This may be very helpful...

 

Yes

 

Pm'd

 

It was working Friday and Saturday, but Sunday something is causing my wastegate to stay shut. I was like whoa buddy almost 20 psi. Made a crap ton of power.

Something mechanical happened. I can't see it by looking at it from the outside

 

All I can say is that I am curious what you find.

 

I'll update what I find. I don't think I seized the valve, but that would suck if I had to water cool it.

 

I need a video of 20 psi rz...

 

The plan was there to be 12 psi video , but high boost was on its mind. Not going to lie. That second of high boost before the cut kicked in was serious power. That turbo doesn't mess around. She likes to party. That bov was loud.

 

That would have been scary fun! With an prayer nothing damaged itself immediately following. Lol.

 

Where can I find this simulator, I’ve looked everywhere
