alright...my opinion....blah. Big whoop. I wouldn't worry about this. WHO would ever get in those cells with 30% to 40%TPS and 1st gear? Those cells in ANY other driving scenario besides what you are doing would be decel. Although, I am impressed, I have never been that far over there (there=lowkpa/highrpm) with any kind of throttle...really never had enough *****. LOL
Keep in mind, (getting ready to speak out of my ***, correct me if i am wrong) 33kpa=hardly any cylinder pressure, or hardly any to scare you with a lean afr. Again, when are you gonna be over there in 1st gear. I'd tune those cells for when I'd normally be in those cells. This is just a note, you ARE at 4800 rpm, that is pretty high for a 18:1afr.
on another side note, i've been helping a few others with 2bar tuning on '03 and up trucks over email and that 10kpa crap really bothers me. Well, this weekend i hooked up (yeh he was a good lay) with holty to screw around with part maf/part sd and that 10kpa crap showed just how crappy it is on at least a stock cam. So many times you will be making adjustments as per 25+kpa scenarios and then you'll be dealing with 12kpa decels. Well all of those are 30kpa on your '03+ ve table.
Yeh so let off the gas at 2000rpm and 70mph(25kpa) and you get a nice lean decel, but off the gas at 2000 rpm and 50mph(12kpa) and you get a rich decel.
My opinion roger tune your ve in 1/4's. Tune 400-1600 rpm and 30-70kpa for example. It will help you tune the way you'll more than likely drive everyday. I don't do 1/4's, I drive the **** out of it, about an hour of loggin, all ways, slow smooth throttle transitions. Keep in mind without that maf what you SHOULD see is lean tip in and rich spike leaving the throttle. Should...should. LOL I said should right?
Don't let anybody fool ya, it's hard, 2bar tuning IMO, there are so many variables and things that can screw with ya. Keep at it.
