Like I said earlier...because the BOV is staying closed, like it's supposed to...the flutter you hear is light compressor surge, and it really doesn't have anything to do with the BOV. The turbo is spooling so fast even at part throttle that it's trying to flow more air than the engine can take. All that air backs up through the turbo and you get your fluttering surge.I might just be an idiot and missed this somewhere along the way, but why does it flutter at half throttle?
hm... i sense some sarcasm here and high horse at a same time... :clap:I'm quite aware of the differences between a MAF sensor and a MAP sensor. So you do know that our cars have both sensors as a stock setup, correct?
See, that's what everyone can't seem to understand here...both MAF and MAP sensors are used together. It's not like the MAF sensor controls the entire engine, and Mitsubishi engineers were kind enough to provide us with a MAP sensor from the factory, just so we can log boost...MAF is a primary sensor in this case, what the ECU reads and follows. That is why the VTA cars with stock set up has an issue being bucking and so on so forth. The all well know issues.( the last 10+ years in the EVo world).
I think at this point we start going in circles , with nothing really proven me wrong So i will let it be.
as people say , "the little knowledge is the most dangerous", which probably apply's for me too in this case. LOL
This has nothing to do with opinion, mine or yours...this has nothing to do with years and years of racing history...this isn't about tunes or whether someone has tuned 1 car or 1000 cars. This isn't about me being ignorant...like I said before, I have no disrespect towards anyone out there.You would have a more credit in this situation if you have a proven tune and racing history which means your tune and work was put it up for test
Racing teams "not weekend wariors" are the best place to test your product street and occasional track use will NEVER prove a 100% reilability of your tune,period.
Those guys who said a BIG no for MAF with VTA , has countles tuned cars and racing history. With the X too. I do race my X since day one in 2008 early springs. Fact many company's test and tryed they first product on my car...
So you are not exactly talking to someone from your locals.
Those people you say you don't care what they say , they do put down something on the table, and your comment on them more then ignorant.
This attituide will not fly neither in the tuning world or the racing.
I could have post seriuos race tuners opinion on this but would be really useless since most of you never heard of them. They do not tune personal cars. I hope you do understand the difference of they knowlidge in the tuning. About the X. Fact one of them is coming to visit me next month or february, who tunes cars and his OWN racing history is more then stellar. Like won the WRC 2011 rally Catalunia rally grupe N with his own evo. Which he tunes and also he does his own suspension work.
By the way this is the guy who helped and designeds the R4 suspension for the evos for Ralliart...
Now I am sorry if I give them credit over your testing and opinion, wheter is a X or the 4G63T.
There is a hard and long head of you with these attitude.
AbsolutelyScott, can you post a link to that graph tephra did up showing maf/map using the lower of the two?
Yeah absolutely.Coolio, thanks man :thumbup:
So that top graph is showing the load is inline with MAP calcs? Could you maybe explain what we are looking a little more (still learning :innocent
I still don't know how you can sit here and say "the primery is a MAF whic the ecu use for calculate the airflow". That graph clearly shows that the load calculated by the ECU follows the lower of the two sensors. If the MAF was the "primary" sensor, then the load would only be following the MAF calculation. It's clear as day, in graph form like everyone likes to see. Again, it's a fact...what you think or what I think doesn't matter...that's how it works. If I could log that type of graph and that information myself, I absolutely would and get several logs of different conditions...but I have no way to do that, so this is all we have to go from.The X is a smarte design and using boit maf and map sensor. But the primery is a MAF whic the ecu use for calculate the airflow. This graph if I am right shows how you calculate how they work together in diffenent condition.
I am also not a tuner, so I can be off here.
I talk to couple tuners and they al said the same about the VTA.
And they told me this about the two sensor too.
