So Im having an issue with WOT fueling changes...even from one gear to the next....sometimes fuel is within a percent or less, then other wot blasts and the dyn. airflow value changes by a couple...
Thanks so much for the response Bill.
I am leaning towards it being a PC issue at this point.
Are there any basic places to start looking at that fix though...(I know yall arent PC hardware...
Got a new computer and Im having a repeated, very annoying issue.
The interface loses connection to the PC and then wont connect to vehicle.
With internet and the mpvi plugged in, I cannot...
Curious about the o-ring gland dims.
I recently modified the fuel hat for my 09 V sedan. I added an aux pump and wired through a -6AN bulkhead. I potted the bulkhead with fuel compatible epoxy,...
This is one of things I wouldnt worry myself with (the desired showing vs your commanded values). You're idling at 706 (average) at 40 kPa. Pretty good IMO.
Are you logging FTC? Is purge on...
I think the dying may have to do with rich after reflash and Open Loop at cranking?
When it is idling smoothly, the airflow is close to by BRAF values. Ive continued to have issues with the...
So I cut spark over and under speed correction values in half and it wouldnt even run...
Put them back in. Messed with P and I more last night and now I'm idling at slightly higher TPS for the...
So I started messing with adaptive idle last night and made some progress with P and I tables, with more tweaking to do. TPS is not doing much at all to control idle (IMO) with shifts back and forth...
Making progress with the idle!
The rich after reflash was screwing me up as it would kill the motor and make it swing wildly to maintain idle, also had to add throttle input to get it running. ...
Tried Big Mikes approach and having issues holding idle when out of adaptive after the throttle blip (wants to stall right away). Dont think its strictly related to Base airflow as I went high and...
Alright, Just figured Id update my thread. A little about me, I am a DIYer and therefore am learning how to calibrate properly. I am more of a mechanical guy by nature, so the computer stuff is more...
Dang...sucks seeing as I have an 09 cts V
Gotcha Bill...so does that mean an aftermarket e67 would have the ability? Just trying to understand since I stumbled upon an old thread with a V owner who was running 2 bar OS.
Thanks TCSS...yea im gonna run blended to 4k rpm then MAF for WOT.
Too many transient issues to not run blended IMO...just based on my experience with previous build.
Tweak IVT gains? I am a newb too, just brainstorming in hopes I will learn something too!
I'm just thinking its a transient fuel issue.
Thanks for adding clarity! How do I upgrade the OS? It isnt available for me in the editor...
So whats the history on this OS upgrade? I have 3.6.26 and it is not available? Am I missing something?
09 ctsV...
@Bill@HPTuners
VE is still 'inactive', it is just idling at higher airflow now, an area that is approx. 10% rich.
Why do I need to update my OS? My e67 already has the VE virtual editor, is there something...

What is a good way to determine mode conditions for the desired FPs with factory setup? And are those mode condition values actual flow or injector flow rate?
Since the injectors are scaled by...
I don't follow the multiple comments that I should try to get in boost but not PE?! That sounds disasterous?
I have been able to get the full range of MAF frequencies now, just harder to get...
Glad you got through to me, I only showed the one final PM.
Copying my emailed questions here.
I am lean on cold start and dead on commanded at hot idle. So offset vs temp or IVT open loop...

[QUOTE=Area47;508435]you should be able to hold 3-4 psi without getting into PE to get the 6k+ hz range with ease. There is a relearn factor to the fuel trims after flash as well. :)[/QUOTE
