![]() They have been quiet on the issue but im sure if and when enough people complain they will "look into it". The first is fueling which is completely doable, the other seems like you said to be an HPT issue. Power wise, it's no good on street tires below 3rd gear or 40mph. I'm 100% sure more can be had from a pro/dyno tune but i would be willing to bet not much more. My Driver demand axle stays above my axle torque right up to the point where my injectors start running out and my Max eng torque stays above my engine torque all the time and stay paralell. Fuel trims are less than 2% all the way to PE. Running about 17* WOT and idles well hot and cold. The MAF tune is actually pretty good and stable. How can you tell if you have a pressure ratio cap? My pullies are about as slow as you can go at this point.How do you override it,some kind of offset? I have rescaled my MAP to 3 bar in the characteristics but have left the MAP estimation alone(I would think this should match the MAP scaling as in sensor range and calibrated range.) With my setup i get about 5.2 psi boost MAP/BARO( I understand this will be off) although it is correct according to my setup. I would assume that to be correct since it does not move. My cam is locked so I'm not messing with the overall camshaft angles. I just got back form an out of town job and will look into it. 5 at idle before, after you get into boost your at a. Since the VVE table is pressure ratio (map/baro) you where say at a. It sounds to me that the baro might be updating when you get into boost. They should all be locked out in any build IMHO. VVT has a hard time properly controlling the cam in Gen 5's anyway. You can rough it in but good luck getting the tables where you want it to be 0- even 10 degrees of cam angle. It's not really practical to do a VVE tune with VVT.It had a pressure ratio cap when the maf was failed and the normal constant to change it wouldn't work. I had a 18 ZL1 that did not want to run SD no matter what I did.I've had HPTuners had a cruise control patch to several different OS's now to fix this. I had the baro for the maf hanging in the engine bay and it would still update to 1.2bar after getting into boost. The MAF / Baro breakout harness doesn't always fix it either. Changing the map sensor config fixes this on most but not all. After you get into boost it will stay at 1.3 bar or so. I've had a couple that would not stop updating the barometer.You can override this and it must be done to get into boost on most OS's. There is a pressure ratio limit that HPTuners limits the max value to 1.I run into occasional problems though for instance. The MAF only tunes with a lot of blowers especially leave a lot on the table for driveablity. I've done more modded Gen 5's in SD than not. What am i missing?It sounds to me that the baro might be updating when you get into boost. If I set it to a 1 BAR map the problem goes away but does me no good since I'm boosted. I'm running a 3 BAR MAP so i set my VE table accordingly.
