You're right EC_Tune, I had more time to play with it, and my fueling was really a bunch stranger than I expected it to be, so after some testing I figured out that if you don't fail the MAF, the...
By the way, here are my two current tunes, one is my MAF tune, and the other is my SD. They are basically tuned as high as 170kpa, I don't go above that with my boost controller.
Well, for me EC_Tune, its easier to just have a separate tune rather than enable the MAF on my SD tune. I did go to all of the trouble of making the MAF tune completely usable, and it is derived...
Oh well, I tried it, and it didn't work. According to the Calculated Airflow Pid it switched to high speed at 4000 even though I commanded it to switch at 6500. The fueling was screwy of course. ...
I have a 2005 C6 twin turbo car, and I like to run a 2bar SD tune with it, but I have been failing the MAF by setting the airflow MAF fail high and low to zero. It works, but throws an emissions...
I have 60# injectors on my turbo C6, and I followed EC_Tune's advice in tuning mine as far as injector offsets, and pulse widths, and I also put the 2bar OS on mine. The only thing is that since...
I am also interested in the modification to the E40 2.5bar OS to allow >512 g/s on the MAF. SD tuning is great, but my state makes us plug our cars into the state emissions computer for inspection...
That is the catch 22 of the 2bar SD tune, you may not pass state inspection. For the 2bar tune, you turn the MAF off by failing it, but when you need to get your car inspected, if you are in a state...
I have the number for the 2bar map sensor, and its Chevy part number 12580698. It is used on the supercharged Cobalt, and is a direct fit replacement for the one bar unit on the LS-2. It is what I...
Glad to help, and good luck with the busted wide band. Hopefully you'll have it back online and ready to tune soon.
While I agree that using boost enrich and power enrich is probably a good way to get more fueling where you need it, manipulating the boost VE table is just an alternate means to the same end, right...
I did just what you are asking. I have a 2bar sd tune on my TT car, and I found that at the torque peak 4400rpm, it wanted to ping of course. I fattened it up using the boost VE table to around...
Sorry for the noobie question Russ, but my MAF maxes out at 5000rpm on my LS2 with 6psi boost. Doesn't that mean its time to go SD? Preferably 2bar?
The biggest thing I see is that you have a 1bar tune on a forced induction car. Its probably worth getting a 2bar tune on it. Also, I am not getting a wide band trace on the logs, so its hard to...
OOPS, it helps if I post my tune. Here it is...:doh:
Mike,
I have a 2005 Corvette coupe with six speed manual trans, and APS twin turbos and 60# injectors, with a kennebell boost a pump with the volume control turned all the way up.
I think...
It would be great if HPTuners could enhance the SD tunes so that it isn't necessary to throw those codes. I hope they can do it. It is a pain to have to enable the MAF to get an inspection. In my...
Ok, I like my SD tune, but here in North Carolina, we have to have our vehicles plugged in to OBDII in order to get our inspections. If there are codes, we fail.
Is there a way to make the MAF...
Thanks for the help Bill and Russ, here is my solution. I think I'm getting the hang of it. I'm going to try this out. I just changed the histogram so that instead of using the main spark vs. rpm...
Ok, but something doesn't add up here. I'll tell you how I found this discrepency, and hopefully you can explain a little more about how the histogram arrives at its dynamic air figure versus the...
So just by having the Mass Air Flow Pid in the table, it affects the dynamic cylinder air in the table?
Just deleting the Mass Air Flow pid from the table will keep the dynamic cylinder air...
How do I disable the MAF pids?
The lean condition is because the car was started and immediately run up to speed without letting the wide band warm up. We were using a tail pipe probe instead....
Take a look at the frames in the main even between about 400 and 450 and you'll see that the primary table values never go above about 1.25 g/cyl, but that the KR histogram is collecting data at or...
Did you have a chance to look at my scan Bill?
Here is one of the .hpl files with the issue. When you look at the dyno pull, during full boost at say 4500 rpm, you'll see that if you look at the kr histogram under button number one is maxed out...
