The "read" button is greyed out on my VCM editor.

I plug in my laptop.
I turn the car to the "on" position but do not start it.
I Resync with no problem.

I?ve already upgraded all the wiring - I replaced 4 Awg with 1/0 awg from the from battery to starter and alternator and distribution blocks. Separate fuse panel for rewired fans relays and headlight...

i upgraded my 540
cca battery to a 800 cca and haven?t had the problem after about 5 starts.

thanks everyone for your comments.

Just checked it. Voltage goes from 12.6 v to 9.1-9.5 v when it cranks.

Will more Battery cca fix that?

I have a 1979 C-10 with an ls1 from a 2001 corvette

My dakota digital gauges reset when i crank the engine to start it. Most annoying is the clock resets.

If you use the ididit acrylic, make sure you tilt the steering wheel up as high as it can go for clearance in the up position

Ididit (not “idiot”)

Thanks for this. I didn?t know that the idiot acrylic was available. Cheapest, easiest solution. I ?installed? / glued it and it works great.

I guess the thing I’m wondering is if the vm scanner displays gear position how come I can’t wire something from the pcm that shows gear position in a gear or a set of lights?

I recently bought a 79 C10 with a ls1 and 4l60 trans. from. 2001 corvette.

When I connect to HP tuners I can see the gear position indicated.

Does anyone have a suggestion of how I can see my...

Can someone share their fan settings for a car that has AC?

Do the enable fan speed and disable fan speed functions work? I have mine set at 0 and 35 - I don't know if my PCM can read vehicle...

i currently have a dakota digital vhx oil pressure gauge and im worried that it may not be accurate

i understand that the trinary switch is a separate system.

given that, how does the pcm read ac pressures?

I recently acquired a 79 C10 with an LS1 from a 2001-2004 corvette and a p01 pcm from a 2002 Escalade.

The fans were wired to a fan controller (dakota digital pac-2750) but they are now triggered...

If I wanted to hook up a separate oil pressure gauge, I assume it's OK to get a "y" splitter cable to connector to the oil pressure sensor, right? I looked for a cable and didn't really find much:...

Thanks. I’ll look into that.

Also, is there some app or monitor that I can hook up to the mpvi 3 so that I can see gauges as I am driving without using a laptop?

is there an accurate oil pressure channel for the 2002 escalade if it?s the pcm for a 5.7 ls1?

perfect. thanks.
i need to figure out how my trinary switch is triggered as well. there is a separate relay for it.

and those connectors come off by removing that single bolt in the center? no tricks or need-to-knows when pulling the connectors?

that?s correct and thanks for helping with these concepts.

hp tuners vehicle readout says it a 2002 escalade 1500 luxury with a 5.3l with a p01 ecm

I have a 2001-2004 LS1 5.7 from a corvette.

I added a oil pressure channel to my scanner layout; the reading came out to be -15.1 psi at idle and decreased to -16.5 at increased RPM!!!??? How to...

I changed the base idle settings - from 625 to 725 (neutral and park) and from 550 to 675 (in gear); no problems changing the settings at all; voltage is now much improved in gear at stop light;...

Ok. Thanks. So it’s pin position 80 on each connector? And I need to add my own wires if it hasn’t been done already?
Thanks.

I recently purchased a 1979 C10 with an LS1 from a 2001-2004 Corvette.

I've come to realize that my dual electric fans are triggered by an old-school temperature sensor that is bunged into the...

Thanks; it just kind of worked out when I connected. I was worried that there might be some kind of conflict with the VIN and the engine but it really wasn't an issue. Thanks.
