You can use a 3 bar LS3 map sensor but the scale will be off so you will have to adjust the tune. I am currently running one on my GTO.

Unfortunately we do not yet have access to T42 DTCs. You will have to wire up the switch or deal with the code.
In a recent e-mail I was told they plan to add it in 2.26 so it could be a while since...

I compared it to a P59 file an the "Flex Fuel" table is populated but I do not see a table that shows at what Alcohol % it starts adding/subtracting those values.
Also the other spark modifier...

I am finally going back to e85 but I'm having trouble with the flex fuel spark tables.

I already have the Alcohol composition sensor installed and the fuel adjusting accordingly.

OK, Yes just sent that file to support with mine so they know what to add. It seems to have everything the GTO people need to get the 4L80e functioning without the relays and fake solenoids ( not...

Does it matter? I know that is an E38 file but they are not swapping the TCM OS over. As far as I know they are just adding the parameters to my TCM OS.

If it is an issue do you have access to an...

I was able to find this file in the repository for a 2008 Chevrolet Express

support need the file that has those definitions added. I am searching the repository for one now.

Dsteck could you please post a read with that added already.

Thank You

sent an e-mail off to support

E40 OS ID is 1250154

T42 OS ID is 24231674

You are the man!! I have been wanting that for quite some time. I could finally get rid of my relays and fake 3-2 solenoid.
What about the extra solenoid for TCC PWM/TCC Enable that the 4l60e...

It would be great to have a legit 4L80e tune but changing the bit mask is something us end users don't have the ability to do.

Maybe I could just go out and find a factory flashed 4L80e tcm...

2005 GTO

I am currently running a 4L80e on my 4L60e tune with the relay to reverse shift solenoid B.

As a result their is no need for the Input speed sensor.

I would like to be able to...

No T42 DTC support?

What gives?

Not that is affects the driveability of the car but the loss of resolution down low is somewhat bothersome. With it scaled 50% the spark table is now doubled and I get no where near the end of the...

I do not even like my tune scaled 50%. 33 would not work. Are their any other ways of going about this?

How would I scale the E40 ECM for 160-190lb injectors?

I currently have my tune scaled 50% which allow up to a 127lb injector.

I have not changed the throttle body. The drop is still their although the vehicle idles much better with the higher min airflow values

I thought that may be an issue also but I have those spark tables identical. I did notice that after I upped the minimun airflow table the drop off seemed less noticable, I'll have to give that table...

that is what i thought but if i watch the wideband it doesn't move whole lot....I'll go try it again

I have a 2005 GTO with a F1A procharger and brute speed blower cam. Ever since the cam I seem to have a significant dead spot in the pedal off idle.

Say the vehicle is at idle (750rpm). If i...
