is there anybody who has a good vvt tuning thread out there? Don't really know where to start.
Must have been looking at it wrong. it is ok. Thanks for replying, next time i will post log with it.
I have a ngk ntk wideband that does not read the same in hptuners. It does not read the same between the table display and the chart display. Is it a setup issue or a wideband issue? Between the two...
Does anybody know how to check the continuity between the pcm and the harness? Can I go from the pigtail at the ac pressure sensor to chassis ground? Will it show anything with a meter and will it...
Yes, all wires are good. Gotta be the pin or something. Still working on it. You know how it goes. Other fish to fry. Thanks
I do have a 5v signal and the ground is good. I also have about 2.8v when I back probe the connector. Yes the ecm and sensor came from the same truck. Seems it would have to be the connection at...

Yes, it is a pressure sensor. The scanner shows no pressure. I let it run up to about 325 psi and nothing. The fans are relay controlled. I hope the I did the screen shot right.

Anybody know how to get the fans to turn on via the pressure switch. It is a 6.0 from a 09 truck with a e38 in a 73 Camaro. The ac is a vintage air unit and they are no help with this. Seem to only...
I set the fans to discrete and they work as they should. Thanks
I am really just starting to get this up and running. It is like the fan is running with the percentages I have loaded into it. I am going to pull the fuse to the second fan and see if that changes...
Does this help.

trying to set up the fans. One to come on at 192 the next to come on at 203. Fan desired% vs. ect set at 51 from 192 to 199 and 91 from 203 thru250. Fan output control vs. current state at FAN...
Is there something that would cause me to lose my iat signal. I am starting to tune with "The ultimate gm efi tuning guide". I have went through the base tune steps and now have no iat on the...
Found it. It was the plug to the gauges. It would only malfunction when it was plugged in. And the laptop was timing out to fast and losing the connection. Thanks.
No. I have a U0073 code. I found where they said it could be a bad conn. somewhere in the can bus data wires. I checked it from the pcm conn. and both looked good. But now my tuners is showing that...
Thanks? I will check with speedhut about the type of gauges. Just got back from vacation for a week. going to get back at it on mon.
The motor and ecm came from a 09 sierra.
Sorry don't really have any. The gauges are supplied with a basic stereo cable. The red or positive wire is spliced into the tan with black tracer going to the diagnostic port. The black or negative...
Sorry don't know what a bus terminator is. But I hooked them per instruction from speedhut. Made a splice for each neg and pos and fed a y off that straight to the gauges. Is the signal different...
I have can bus gauges from speedhut. I have tach, oil press, temp and volt. I have the readings on a scan tool but nothing with the gauges. do I need to reconfigure something in tuners. It is a e38...
will do thanks
the donor was a 09 Silverado and it is a e38 pcm

One more thing I don't understand is that the DTC's between the Editor and scanner are not the same. I would think that they would be.?
