Awesome. The 3 bar, or I think they refer to it as 2.5 bar, GM sensor has been in there for the duration.

Awesome. The 3 bar, or I think they refer to it as 2.5 bar, GM sensor has been in there for the duration.
Car has been through multiple combos and currently runs a P01 2 BAR, FLEX FUEL enabled tune.
I've flirted with disaster dozens of times, running 19-20 (or more)# of boost, and no ability to tune...
Not all that math handy, so Option #2 is probably out, lol.
I'm still at work, so can't do a whole lot of researching at the moment.
Any idea if a P59 swap is a plug & play deal, or will I need...
I have a 2 bar OS w/flex fuel in my car, a 2000 Trans Am.
I have had a 3 bar MAP sensor installed and functioning through the previous 2 engine configurations, one a 3 bar OS with turbo, and one, a...
LOL...nevermind...brain fart.
RIGHT CLICK and change UNITS...fixed.
On my turbo car, using the "BlueCat" process, I needed a fair amount of "lead time" for my 1-2 and 2-3 shifts to happen when I wanted them to...
4L80E, Triple Disc converter, FWIW.
4100+# Car...
Thanks Pal...LOL.
If I didn't literally just have a RoFo open up at the end of my street that sells Flex Fuel, I'd still be back in 2009...lol.
I got rid of my 8-71 blown big block Chevelle...
2 years ago, my car was a turbo car. Same engine now, so low on the compression for me, lol.
The E85 seems to make my car run more consistent as well. First time out, drove 45 miles to track,...
I run straight E85 now, using a sensor for ethanol content measurement. Still gets better MPGs than my old truck, and has zero knock under any load...even with all of the flex fuel added timing. So...
I use my standalone datalogging function mainly for dragstrip run recording, and sometimes just as a basic check-up datalog of my daily driver.
Never an issue, ever.
I had to license a...
Good find.
Unfortunately, mine did it with factory gigantic air intake "tube", as well as with the Airaid simple intake tube that replaced it.
Installed a catch can, which is catching slight amounts of oil.
Cleaned intake and top-end, using SeaFoam Top Engine Cleaner.
Left BURST KNOCK RETARD and DoD TURNED OFF
These things did pretty...
I think I used the same one that you found, a 2002 Silverado with 6.0/4L80E, and flex fuel adapted already...but it now appears to be gone?
Are you still able to see it in the repository?
Just to update...
As stated, I have unlimited 2002 Silverado credits for HPTuners
Did a "Write Entire" from my existing 3 bar SD OS (12212156 > 1261002)...
back to a STOCK TUNE 12212156 OS
...
Awesome. Thanks for the replies everyone.
I have unlimited model year 2002 Silverado credits, and all three OS "tunes" are 2002, then I shouldn't have to buy any credits, should I?
Current OS (in the car now), Stock OS (I was going to use...
I do not have the original file.
3 bar OS upgrade was done several years ago by unknown party.
If I am understanding, I cannot simply take a generic factory stock 2002 Silverado file and Write...
If I do NOT have my STOCK, FACTORY tune, can I simply find a STOCK FILE in the repository, and do a WRITE ENTIRE?
The end goal is to convert to a FLEX FUEL OS, but I currently already have a 3 bar...
Would it be feasible and/or EASIER to return (WRITE ENTIRE) the PCM back to a STOCK 2002 Silverado 6.0 OS first...then go to the 2002 Silverado FLEX FUEL 2 BAR OS setup?
I do NOT have the STOCK...
Right now, I am running straight E85 on my 2000 Trans Am.
Mild 6.0, 4L80E, dual 255 pumps, 60# injectors
All I did was change the Stoichiometric setting from 14.62xxx, to 9.68, and it is running...
I think I'm going to go for it.
I have access to chassis dyno so will do some street and idle tuning, then head there.
I'll cross the nitrous jetting part when I get to that point...using my VE...
Thanks for the reply.
Not that it makes a difference, but my OS is a 2002 Silverado. I guess whenever that was done, it was easier since car is a 6.0/4L80E setup?
The E85 station that recently...
2000 Trans Am, naturally aspirated, 400ish hp
Car has 3 bar SD-RTT os still, from when it was a turbo car, although I do run a MAF now.
Assuming all else (as far as fuel supply) is setup to be...
Are you able to CLICK on the small letter "S" that I have circled?
If so, the labels should change...
