Congrats. I'm surprised that worked because I didn't think the veins could move fast enough to cause your sporadic boost readings.

Why did the turbo " unlearn" to begin with? I hope it's not an electrical gremlin that caused the unlearn.

 

It all started while towing a large camper. I was at a stop light about to go up a long steep hill and I gave it a little too much throttle and the tires broke loose. As soon as they did I let off the throttle. My geuss is that with so much load on the engine and then suddenly "free spinning" combined with the sudden let off of the throttle that something might of jumped or became disoriented with the VGT's. I'm no mechanic but that's my theory if it makes any sense. As far as the Dashboss it's not reading accurately so I don't think it's the engine it's the actuall Dashboss

 

your dashboss isn't screwed it just needs to look at a different sensor. when it hits about 25 it maxs out and goes to zero or negative. next time i go out to my truck ill screenshot which on reads right under high boost

 

Thanks 250andex that would be greatly appreciated.

 

This shows boost and zero. Notice the Capital boost

 

The one that does not go to zero or negative is MAP g Boost / vac gauge

 

Also make sure you have your parameters set up correctly so you don't get gauge, absolute Ang Hg" messed up

 

Awesome I'll check this out tomorrow, so what parameters do I want, the gauge, absolute or the Ang Hg?

 

As long as you know what it is and do conversions it doesn't really matter. I do controls so I usually just convert everything in my head because so many different units are used in the power plant. I just noticed you had really high exhaust pressure that I believe was reading absolute so if you subtract the 14.7 for atmospheric pressure you pressure would have been right on. So I guess make sure everything is gauge so it doesn't throw off a highly educated guess from the guys here because theirs an awful lot of knowledge on this board that guys are willing to share but you gotta give um the right info. I've learned an awful lot on here and hope to keep getting more help like you because I'm still pretty new to this.

 

Ok I see what you mean now, it doesn't matter which it's reading just as long as they are all reading the same type of measurement. I did that afterwards once I noticed it but some of the parameters wouldn't let me read the same, I found on line somewhere what to read for each parameter, actually I think it was the link that someone sent me here. Thanks for the help!
