should i turn on sensor performance?
i turned off all 3 maf dtc's
i dont know if the injectors are right the tuner did it. they are fast 57 lb/hr. so turn off the dtc for the maf and it should run?
i had to copy this tune manually and now it wont stay running not sure what i messed up. can someone please help me out. new ecm is the tune i tried. the other is the one that wouldnt write to the...
These are the only options I have.
For some reason I can open both files and compare them but I have no ability to copy over differences.
awesome. Looks like I lucked out this time. I'll try to copy the differences tomorrow and see if it will write to it. Thanks for the help
I honestly don't know how to tell. I assumed that all 2000 ecm's would be the same with the exception of the vin
This may sound like a dumb question but will that work with a 4L80E segment swap or do I need to have that tune emailed out and added?

Service number of the original is 09354896 and the new one is 09354896. The only other numbers I can find are on the blue connector. Old one is 2230L22735, new one 0630L20919. You can tell by my...
It's a 2000 silverado with a replacement 2000 ecm. Trying to upload my segment swapped tune into the ecm. Not sure where the ecm numbers are that you are looking for.
I had to replace the ecm I'm my silverado and tried to write my tune to it and it gave me a calibration mismatch error. The ecm has my vin stored into it and it read the stock tune and saved it. I...
no. when I originally built the engine and had it "tuned" the truck ran good. I should use good loosely. but the truck did have much more power and could climb to 6000 rpm. I drove it home from work...
I did break it but not because of the tune. I broke a crap comp cams valve spring and slammed a valve into a piston.
I agree about paying to have it done. but the last thing I wanted to do was waste a tuners time. I want to get it running well enough to drop it off and accomplish a dyno session. knowing know that...
I didn't set this up. I paid a tuner to get it to run and drive. he wouldn't dyno until I broke the engine in. on the other hand I have no clue what the hell im doing to where to start making...
here is a data log
cats are now gutted. still not seeing a change so either my plugs are fouled, coils are weak (original square coils with 230k) or my stock pump is not providing enough volume
i have a fuel issue. tried to idle it to warm it up and my passenger cat was glowing.
what should i adjust and how much timing should i add to start?
i built the engine and had Synergy set up my tune. i never got a chance to have it dynoed before i moved out to Virginia when i was discharged from active duty. before i left the truck would lose...
its easy i take the chip out and ship it back for a free reflash and reinstall when i get it back. how ever you want to view it having to lug around a laptop and my equipment to make changes...
