Well I 've finally decided to dive in head frist to my HPTuners 2bar sd operating system and tune. Any tips tricks or advice is appreciated.

 

I second that, I will be doing the same later this month.

 

Tweek little at a time and

 

You did the right thing.
How much boost?What exactly is your setup?
if you want email me your file.

 

Running a p1sc w/ 8 psi on basically a stock engine. I removed the FMU and installed a 255lph pump and 60# injectors. I will be using a wideband of course.

When tuning the VE table in boost won't you get %error due to BE?

 

The b.e is acounted for, so no not due to b.e. Well I guess the answer is yes you will get an error if your command a/f is different than your true a/f...

 

Ohh. That makes sense. I read not to enter PE when I first started VE tuning on my stock OS. I assumed the richer commanded AFR would throw things off. Now that I think about it that was probably for tuning w/ LTFT's.

I was planning on starting yesterday but ran out of time before that sorry excuse for a Superbowl. Hope to Reflash my OS and start this evening.

 

HELL YEAH!!!
The 2bar OLSD is deffinately the way to go for FI. My truck has never run better or been more consistent. I wish I had gotten off my *** and done this sooner.

I still have some fine tuning to do. I'm commanding 12.5AFR in the BE table. It seems to pull pretty good. Does this sound a little lean?

What makes better power in boost? Richer AFR w/ more timing or back off the timing a little and run a leaner AFR (relatively speaking, I don't think I would go any leaner than 12.5)?

Thanks,
Alex

Oh yeah, HPT is the ****!

 

I shot for 11.2-11.5....

 

Mine seems to bog down at that rich of an AFR. I will play w/ the BE table once I get VE dialed in 100% though. I guess I could probably run more timing at that rich of an AFR which leads to my 2nd question.
