Hello!
My question is simple:
I downloaded several random logs from old posts here from the group and realized that RPM rises steadily.
Example:
1-2-3-4-5-6-7-8-9-10

And I noticed that in my logs, the RPM rises oscillating.
Example:

1-2-3-2-3-4-5-6-5-6-7-8-9-10

I wonder if anyone has ever had this problem. I'll leave some pictures so they can see.

For more information, you can see my latest YouTube video. When I accelerate the car, you can see the RPM pointer displaying the same "swinging" behavior of the log.

Does your boost also oscillate?
 
Should check without the MBC and see if the engine RPM and the boost raise smoothly or not. Also check pre-turbo exhaust leak (between head and manifold inlet, manifold outlet and turbine housing inlet)

I downloaded many logs and i found one thing: all 2g stroker 2.3 has the same behavior in the rpm line when WOT.

Maybe this is the reason?
 
Can't listen to your video at work currently. ohh, I also don't know that language anyway.

What are the two (3) blue devices hooked up? What brand are they? Look super generic.

Are you running an internal or external wastegate? What tuning program are you using? Ecmlink?

Why not use an electronic boost control that ECMlink suggest?

Why are you tapping into the valve cover port? What is that Tee hooked up to? Need to add some subtitles with that video.

Hello!

No problem! The video is in Portuguese. I just posted to show the final part when I was speeding up

It's a generic 'manual boost controller', purchased on eBay. This first part was just to show his installation. Even without it, the RPM line presented this behavior "serrated"

Why not use an electronic boost control that ECMlink suggest?


I already bought the INGERSOL solenoid indicated by EcmTuning. I'm waiting to arrive (the import takes about forty days). Meanwhile, I put this booster just to see how the car would behave at 20 psi

Why are you tapping into the valve cover port? What is that Tee hooked up to? Need to add some subtitles with that video.

As I said, this first part of the video is "irrelevant." The post was to comment on the RPM behavior that goes up and down (as you can see in the pics). The video is from my youtube channel, I did not do it exclusively for this publication.
