Izaks, Logging that PID it shows 0 and remains at 0 regardless. When the fault code sets and P0606 comes present, CPUFAULT steadily shows 0. I tried a new CAL file from Steve @ EFIHarness, but still...

Any walkthrough on how to do this? That sounds like exactly what I need.

Bump, any help would be greatly appreciated. Simply at a loss with this car and the symptoms.

Thanks joecar,

If you have any questions feel free to ask. I realize it’s an essay, but unfortunately I had a ton of information to lay out and always feel more information is better than “Why my...

Well, more to comment on now. Attempting to go back to the beginning and start fresh, I did a full flash to eliminate the VATS Patch and all changes and see what my results would be at this time. The...

Hi Everyone,

At my wits end on this project and have surrendered to needing additional help from the community here. I will give a quick summary of the vehicle/engine/wiring application and the...

Just to close out this thread. A tuner in California named Steve, who operates a company called EFIHARNESS, was able to modify my OS to run the vehicle entirely standalone. Steve was a life saver!

Bump, don't want to bug everyone just wondering if anyone has found a way to permanently remove "Reduced Engine Power". Would like to ensure it doesn't come back randomly, especially while racing

Hi joecar,

Thanks for the reply. So, I have logged Pedal Percentage, and it reads 100%. So the accelerator is definitely seeing the correct percentage.

Everyone on the Cobalt forum says the...

Hi Everyone,

I am building a 2006 Cobalt SS 2.4L LE5 N/A 5-Speed Manual, to become an oval track racecar. I have removed a lot of the interior wiring harness, and am working through some issues...

I will try and upload a picture later this afternoon when I get a chance. The symptoms are strange. Unfortunately I really need to be able to log either through Serial or Analog to get this tune...

I soldered the connection at the middle of the cable, and can verify with a multimeter I have correct continuity. Also have correct readings showing up when it intermittently connects to the...

This is a brand new serial cable direct from EFI Live? Could it still be broken? I do not have a spare and live in Canada, so its not easy to get a spare cable

It is working correctly, and I second that by wiggling the connector and it's reading matching the LM2 Display. Connected LM2 to good 12V and still have the same issue

The cables I used to build this Null Modem was an Innovate 3812 and a EFI Live V2 Serial Cable

Purchased direct from both companies

Ok I'll go do that right now and then report back. When I built this cable, I connected Black to Black, Red to White, White to Red, and Left Blue Unconnected. Is this the correct wiring for this...

I am using 7.5 EFILive Scan. I am currently recharging the Booster Pack to ensure it's going to give me the kind of voltage I need. May also hook it up to a known good 12V Source. Could this...

Hey,

This message is especially for Joecar, as I've followed his steps to try and make this work. I have a V2, a Null Modem Cable I made, and a LM-2. Used the Innovate and V2 Cables, and...

Joecar, That is the current tune file and log from my last attempt to pull.

A couple concerns we have.

1.) The Wideband LM-2 Shows the correct AFR, but when I plug it into the bottom of the V2...

How do I post them as attachments? I apologize as I am new here. Unfortunately I don't do much of the tuning myself, but my tuner is busy this week and I have a pull Saturday night

Hey Guys, Looking for some insight on a tuning issue I'm having with my LS Powered Sled Pulling Truck. First, background on the truck.

2004 Silverado 2500HD, Stripped and Cut Down Competition...

Yes I have read the manuals and am just lost, seems simple but it just won't work for me it seems. I grounded the black wire, powered the red wire, plugged the yellow wire into the Positive...

Hey Guys,

Have a V2 which I use to tune my Duramax, and have now built an LS Powered Silverado Pickup Truck. Need to connect my LC-2 to my V2 to start logging through EFI Live Tune. My question is...
