I've been chasing an issue since I've gotten my car running, and it seems like I'm running into a wall every time I try to track down a cause. Bottom line is, about every 2-4th run cycle, the SES...
Yep that I've actually DL'd already, outside of the injector tables I presume the other values are scaled in the same manner then?
EDIT: Just realized there are more tabs I didn't notice, thanks...
Just wondering if anyone could shed a little light on the subject for me. I've recently completed my LS3 conversion in my '00 WS6 and am now running the car on the original LS1 (heads/cam) tune. As a...
Just wondering if anybody esle has observed this. Logging was very smooth, very much 'real-time' in v7.4 of the scan tool, whereas v7.5 seems to be VERY choppy. Now I've verified all setting are the...
Very close but not perfect, averages about .1-.2 richer than commanded.
Nothing random, I drove it after the installation to see how much correction the PCM needed to hold stoich and I based the changes on that, and yes I reset the trims each time I logged and drove...
So after having my car running very well since updating to '02 OS and performing a 'from scratch' tune, I made some small changes by adding a set of ported MAF ends and installing a FTRA setup. Now...
Just wondering if anybody esle might have a little insight on what I'm experiencing at the track with regards to erratic AFR's. On the street I'm getting very stable AFR's and my LTFT's sit anywhere...
Kinda odd isn't it? Conventional wisdom tells us leaner hotter mixtures generally promote flame propigation much quicker than cooler mixtures of the same density, and when you consider the increase...
Commedian.. :hihi:
Yessir :rockon:
Generally speaking, 13.0 seems to be the universal target for N/A application with typical compression ratio's. FWIW, I noted very little change in output at the dyno with my car when running as rich...
Funny I just read this after I posted my experience switching from '00 to '02 OS, it's VERY much worth it! Simplicity and diversity extended, you'll love it :)
Just thought I'd share my brief experience, I recently decided to update my original 2000 software on my T/A to a newer '02 OS and cal., and I couldn't be happier! For one thing the actual tune took...
It's inevitable that you'll develop some peaks and valleys, especially if the vehicle in question has substantially modified airflow characteristics i.e. bigger cam, heads etc..
A little smoothing...
lol! Have a cold one on me!
Granted it's not a GM, but what you're describing is prototypical of a Honda alternator failure (I work for Honda, don't hate me lol). Just my .02 ;)
Just wondering if anybody else with a WS6 has debaffled the hood and noted the difference in your logs? I honestly didn't think I notice anything but I actually noted a solid 3-4% swing lean in the...
Assuming you set CFOL so that the highest columns read what your PE AFR would be tuned for (say 12.95 AFR just an example number), and you dial in the VE table that way, what would the difference be...
How exactly did your IFR table end up looking when you finised? Like I said mine is not a dead straight slant like the typical stock line is, it's got a touch of curve to it, yours?
What I'm looking for here is to see who else has modified their IFR based on logging the MANVAC pid to nail down your true IFR, and more importantly what did your IFR table look like? I ask becuase...
I've had similar problems as you, my problem is repeatability or lack thereof. I've gone through the AutoVE process and I've got my LTFT down to no more than -5% LTFT for the better part, however...
From what i've read this is what I belive to be true about my stock '00 PCM:
I can upgrade to a newer factory OS by simply copying my calibration values to a stock '02 T/A map.
I cannot upgrade...
Outstanding, thanks joecar!! :cheers:
