I ordered this morning and needing a credit I purchased. I have been unable to login (says my login is incorrect-which I know it isn't). I have even tried to reset the password to no avail. I am...

Can you post a stock file for us to look at?

What does the G1219 and 1220 do? Is this only for cranking/turn engine over? Please elaborate.

The stoich of ethanol gasoline is around 14.2-hence the reason i adjusted it. Look at Ford and the new coyote engine the stoich is at 14.09 for todays fuels. As far as the idle being at 1000-it is in...

I have attached a file for a E38 which I believe to have removed the vats. Unfortunately I have 12v to one side of the fuel injector connector but don't have any ground at all-ever. When I turn the...

I cannot explain why the fuel trims zero out. It is only happening on the dyno. Stock or tuned.

Bump to the top.

Here are the files which have been requested.

Exactly, this is a 100% stock vehicle that it was doing this with. I was asked to post a log file. Here is the stock tune file. It doesn't matter tuned or untuned it does it.-j

Yes, I did. As far as the modifications it is stock engine, cold air, headers, catless mids and cat-back.

After tuning this car- the owner claims that the serice soon light comes on (supposedly the oil change notification). Any answer as to why? Attached is the file.-j

Here ya go. This is a completely bone stock unflashed tune. This is the way it came from GM.

I don't think so. The reason i say that is I have tuned tons of E38 vehicles and no issues so far. It occurs once the tires turn over and the traction control/stability trac comes on. After that i...

Anyone had the issue of the trims showing 0 (zero-flat line) while on the dyno. But when you get on the street they act properly. I suspect that it is something tied into the traction control. -j

I would check into the mechanical side of things. Typically, when we are banging the keyboard with no response or large changes to get a small response validates a mechanical issue. Force the car...

Paul,

Would you please delve into the procedure for this? I have read the manual and there aren't any clear instructions for calibrating the analog inputs. I have a new v2 which isn't reporting...

If i purchase a Flashscan and for GM gas vehicles initially would I be able to upgrade to tune Duramax and Cummins vehicles at a later date? It appears that the V2 controller is more if you have the...

Are my eye deceiving me or is the tuning now available? http://www.efilive.com/supvehicle.aspx

Sorry I meant to say 06 CTS-v I edited this post.

thankyou and glad to be part of the forum. I am new to the efilive software. Where do you find this pcm# which I will need? I believe it is a 05 Colorado with the I-5. The list isn't even showing...

Is there going to be any tuning available for the Colorado/Canyon in the near future? Also interested in the Cobalt tuning as well. Any information would be greatly appreciated.-J
