Copy this one over. Clean and runs good.

Here is a 06? 1500hd i tuned for example.

The 4l80e has a very tall first gear. Those speeds sound reasonable depending on the axle ratio, tire size, rpm. They set the shift speeds way low in 2500s.

Disable ltft and dfco. Get a log and see how it looks.

Nevermind, found it on a 02 z28. Im sure i have that in a xdf for other os.

You have a file with 2282 editable? im not finding it on any trucks.

Also, dont forget to make sure your map sensor data is correct. Nothing wrong with the intake choice but i always install the 4 to 3 bolt adapter and run the stock tb with the gen 4 intakes at my...

See if this gets you starting, idling, no flashing cel at idle. Make sure dfco is off while tuning ve and maf.

Here is my file for example.

Try multiplying it by .5 or .25. I was having a surging issue with a silverado while ac was engaging. I left a few degrees in there but probably took 80-90% out.

May have had a voltage fluctuation during the write. If it will not write in vehicle try it on the bench.

I appreciate it, according to jakes the 4l80e will have inertial apply issues over 6k. The drum upgrade and pump upgrades will be needed at 7500+. Not saying it wont have issues under 7500 but if it...

It will be a portable unit used on pre-can vehicles.

Do you have the data to input for the map you linked, map and iat? That may be a really good option.

I thought the same on the trans, its a built unit but that is a lot of torque going through it. Ill probably work some TM back in and see how it acts. The vehicle has no o2 sensors and is fully ol....

Got the build sheet. 6.2, 243 heads, edelbrock pro flow intake, 80mm turbo, btr stage 4 turbo cam fic 1200h injectors, 90mm tb, non lockup verter. I believe ive finally got a decent startup ready....

Ive used it on n/a gen 3 truck builds stock and cammed. Definitely a noticeable difference in power and will offset the difference in bank to bank trims.

Made a couple more edits to make me feel better. I included another scaled file from the same shop, different truck and owner. Notice the ve similarities? These are not getting tuned. Also, the...

My bad for not giving more info. I dont have specifics, 6.2, cam, turbo, intake?. The main issues were in the starting, idle, i believe pulling in gear(the braf was still unscaled). The big one was...

I was sent a tune for a 900 hp, now 6.2. Here is the file i read and some adjustments i made to get it closer for the new engine. Old tune was trash. Anything i missed before i do the first startup?

Id really recommend going to a 2002 os file. Here is a file i made with some background changes to make this work. I have lots of issues with the 99-00 trucks starting.

They really done a awesome job on these things. Considering the cost of licensing maybe we should have more than 4 useable parameters.

Ive had a duramax ecm with the all "y" vin. I was guessing they used some box programmer on it or some mail order efi tune with a generic vin.

One of the other forums has some members working on p10 flex fuel capability. Pretty sure there is some tables in the background to make it work but may be some time off.

Here is one setup and ready to go for...
