Thanks again then. I'll save the money for EFI live.

Which means a hundred bucks and shipping since I bought it three years ago and don't still have the receipt?

Still no advice?

It also acts the same as when you plug 12v power directly to the power port on the top of the tool with no obd2 connection or computer hooked to the db9 connector on the tool.

Just got back in from break. When plugged into a bone stock 03 Silverado it will not recognize the vehicle for vin, or show trouble codes. Vehicle type couldn't be read.

I can't have a truck around for awhile. I'll look into it when I do. You guys have probably seen about everything with these things. What happens when it loses power during oem backup? The memory is probably corrupt. Whatever kind of memory, eprom, or whatever, it never received the right sequence ...

I'll try and see if I can find another vehicle to test it on. Please keep an eye on me here though. Like I said, trying to get anyone on the phone is downright impossible. Thanks again

Back when it worked right, I never had any of these problems. I know there has to be a reset feature on this programmer. From ...

Well, I have no idea what other communication would be causing an error, but when I plug it in to the OBD2 port, it lights up and works. It says the last tune written is the "Original Backup" on the screen. When you try to ask it anything (Show VIN [Can't read vehicle type] -or- Performance Tune ...

No, it gives a waiting screen and then it can't display anything, can't read trouble codes, can't recognize vehicle type.

I'm new to the forum because I've never had any problems until yesterday. I went into limp mode because I was pussyfooting passing a car in overdrive (it happens, had my programmer turned up higher than I should have for daily driver.) I decided to back it down for awhile. When I went back to the ...
