Where you going to put that wideband gauge? Which model gauge too?

It has something to do with the Diablo tune. I went back to my stock file. I did a comparison between the Diablo and stock CTSV tune. Would you mind taking a look? I put it into Excel so I can compare easier. Would you keep the supercharger settings like the Diablo has? I am going to start modding the stock tune and go from there. Here is the data from both Supercharger Tab changes. The rest stayed unchanged between the 2.u have to log more, dynamic airflow g/s, cylinder air g, engine torque, inj duty (might be default maths), knock retard, idle adaptive adv, or more idle pids if u have them, inj pulse width both banks, also i stay away from the SAE pids they are generic and can be better to log the sensor if ur only using your vehicle,
ur also running very lean in the bank 2 when WOT with that boost i wouldnt do that again until u figure out whats going on, according to the 02 sensor it starts of about stoich and as rpm goes up it gets leaner, too much of that will cause issues, there looks to be a decent fueling looking at stft different between the banks so id look into that also might be part of whats going on, the sensor isnt doing what it should be cycling around stoich in closed loop so its either a issue or sensor is old and failed but DONT GO WOT TILL U SORT IT OUT if u were logging knock it will show u if its potentially doing damage but with the data u have in the log it seems ok might just be sensor but check it out asap
That is what I did. I am putting together an Excel table of the differences between the stock file and Diablo in HPT. I will upload both tunes if you wouldnt mind taking a look. With the Diablo tune, its running rich, stuttering at part throttle when I first press the pedal. Its also throwing a P219B (Fuel Trim Cyl. Balance Bank 2) code after an hour of driving.looks like the diablo has just disabled the limits to the supercharger so its not worried about which is fine, the torque just looks maxed out which can be fine if its just a limitation table, id have to see it in the tune file but so far looks ok, yea prob best to start fresh as u dont know what going on in the background, i wouldnt put a stock tune in it but if u have your stock tune and the read from the diablo tune in hpt then u can copy over the differences to the factory tune that was u dont get any odd background stuff if hpt cant see it, and always be aware of fueling see how it goes and start making adjustments
All that is done to the engine is smaller pulley, headers, full corsa exhaust (no cats) and AFE intake. What would be fine to keep from the Diablo tune? I can add that stuff to the stock tune and tweak the rest.very little changed really, vve looks stock, maf is changed and its put in so called maf only but thats not right just lazy tuning, is the vehicle mostly stock or modded ? dosnt really take that long to dial the maf in as its only airflow if u can get an idle and round town and then from low 4th to top end of 4th with wideband u can pretty much dial the maf in with that (4th is getting up there tho which is why dynos help) vve will need work but that can take longer as its load based but u can also do that over time once maf is dialed in the vve can be adjust to suit over time, PE is rather rich so if boost isnt too high u can bring that back, the stuttering is prob the rich PE and low timing in the lower rpm high load areas which may be fixable if there is no knock for the fuel used and it may like it leaner then it is can all be things to test out
Here are some screenshots of the differences of the tunes:very little changed really, vve looks stock, maf is changed and its put in so called maf only but thats not right just lazy tuning, is the vehicle mostly stock or modded ? dosnt really take that long to dial the maf in as its only airflow if u can get an idle and round town and then from low 4th to top end of 4th with wideband u can pretty much dial the maf in with that (4th is getting up there tho which is why dynos help) vve will need work but that can take longer as its load based but u can also do that over time once maf is dialed in the vve can be adjust to suit over time, PE is rather rich so if boost isnt too high u can bring that back, the stuttering is prob the rich PE and low timing in the lower rpm high load areas which may be fixable if there is no knock for the fuel used and it may like it leaner then it is can all be things to test out
