kinda what i figured. Thanks

So what is the differences between 3.6 and 3.7 beta? I have downloaded the beta and other than some tables on their own tabs i dont see anything different. How is 3.7 better than 3.6?

i run ID1000s in my car running a 04Z pcm and use .008 as my min fuel milligrams

So im assuming this has been done using the user defined parameters hp tuners has but I have no idea how to do that stuff and i can not find a good write up on how its used yet. I will figure this...

I havnt. I went to the complete 04zo6 os. My car is on jackstands getting a bunch of upgrades including a new motor so it will be a couple of months before it gets driven. Honestly even if the flex...

I moved the alternator field wire from red 52 to red 75 and i do longer have the charging fault. Only fault i have left is the map fault. everything seems to be working fine, both fans work, throttle...

his screenshot above shows it working

So basically just do a complete 04 z06 segment swap? then turn on the flex fuel with the master enable?

I think i need to move the wire in now green (old red) 52 to green 75.

the code im getting is for the f terminal

This is what im using. Keep in mind though I havent 100% verified that flex fuel is working yet. I ordered the flex fuel kit today and when it gets in i will plug it in and see if it reads the...

I wouldnt think they would be much different

So it looks like there is a alternator L Terminal on red 15 and Alternator F Terminal on red 52. which one do i need to move to green 15?

This is what the guy from lt1swap told me.

The PCM’s are pretty much pin compatible with exception as you noted, extra o2 sensor grounds on the 03+ blue/green pcm. The alternator field duty...

yes. the only thing different between the 04z and 04 tahoe pcm i got that had flex fuel already enabled was the fuel segments. I emailed they guy at lt1swap.com awhile back and he told me if i plan...

they seem to be working just fine the way they are

I think the later models are grounded back to the pcm because the pcm modulates the heat in them where the older ones do not. Im not changing to the newer style o2 so i dont think i need to change...

Well progress has been made. i turned VATS back on, attached the maf with a coupler and relinked the pcm/bcm and the car started and ran for about 7 min before i turned it off because the garage was...

ok ill turn it back on and sync the pcm / bcm and attach the maf to the tb with a coupler tomorrow. Its cold as crap and i dont have a garage heater right now.

kaganader that file will not open. It says unsupported.

i havnt synced the pcm and bcm yet. I do have VATS turned off. I basically did a copy all of my old tune to the p59 earlier and loaded it to the car which is why the throttle wouldnt work. I looked...

Well i did the 04 z06 segment swap for everything except the fuel segment and copied all the things i needed from my original c5 tune over. I have to push the throttle all the way to the floor and...

I see that a 2004 z06 uses the same OS so would it be better to segment swap all the 04 z06 segments over to my 04 tahoe pcm except the fuel segment? Now that i look at the segments the only segment...

I have a p59 out of a 04 tahoe. I plugged it in the car today and read the file and it is already a flex fuel enabled pcm. What else are you saying i need to segment swap to make it work? I havnt had...

is the suv os compatible with the factory c5 tac module and throttle body? i know in the trucks you have to use a x link to use a ls2 throttle body
