Hey all, been out of this for a little bit (never was real good at it period) but i cant figure out why this crate engine will start and then die like the vats need fixed. I cannot find the vats in...
actually mine is saying timed out
I have had this issue with two different ecu's . both on same engine (changed ecu to troubleshoot) and it happened again earlier on an ecu that I had made several changes to already today and tons...
That was my mistake after taking apart the harness to check for any problems. 74199
So I changed a cam on an already tuned engine (sold the engine and customer wanted me to change the came from the Comp Thumpr to the Comp Big Mutha Thumpr cam). Problem I have is after only a cam...
Hello. i hope this explains a little bit. I am still pretty green at this as well. The default layouts are just some of the things you are able to look at with the scanner. There are tons more ( I'm...
Have you had any luck with this?
I had 2 different O2s in it with same results. I guess something has happened to the wiring. It basically just sat for a while. Oh well nothing surprises me with this stuff. Lol. Thanks for the...
I actually ended up changing the TB to a Top Street Performance 92mm TB. Uses the GM IAC and TPS. I personally couldn't get it to idle down til I did that. But then again I'm not the brightest bulb...
Car sat for a while and battery was dying. Now has new battery but car will not run right. Here is a log sitting in the driveway

are you using a wide band for AFR error?
Check to make sure your IAC is wired properly. The Holly Sniper TB I worked with came with took a 2000 to 2003 Dodge 2500/3500 V10 IAC. Plugs up the same but wires differently
Thank you very much guys! I appreciate your responses!
I'm trying to locate a factory LQ9 file that is a cable driven throttle ecm. Couldn't find anything specific to LQ9 in the repository. Any help would be greatly appreciated.
Just had an ecm that wouldn't take throttle an a dbc set up. Changed tune to a known working tune still wouldn't take changed ecm with and put the same known tune in and pesto! I'm new to all this...
Its big tires, heavy truck and mud. Made good power on my engine dyno for the mods.
Thank you for your info Higgs! I pretty much set it on an engine dyno at 11.6 to about 12.2. The it was OLSD and the timing was about 28 through the range with no knock ever showing. It will go to a...
Yes 5fdp you are correct. The truck will have like a 3000 stall and spend the majority of its time running wide open
If you were to tune a 6.0 lq4 with a cam, port & polished heads, cut .060 for 10.5:1 static compression. This will be going into a mud drag truck. What kind of AFR's would you look for before...
I really appreciate everyone's help! I well try to work on it more on Monday
Thank you for your info. I am confused. They worked fine for the VE. I have tried a different ecm. Not sure what i have going on. I will look into it more today. Thanks again!
Where in the tune of a 6.0 truck can you alter the O2s working? I can't get any activity from them after doing my VE . Changed out O2s and checked continuity and everything is fine. Trying to do...
I was told there was a place in the computer to change a dbw from plastic to metal or vise versa . Is this true? If so where is it in the ecm? Can you turn it off if you change intakes to a dbc? Im...
Dont start the engine and immediately put it in gear. Let the oil psi build up first. The engine can run for a short period of time without oil psi due to the oil already on the bearings and no load...
