You can get a picoscope to work with your laptop pretty cheap to diagnose signaling issues, etc.

M1008 Cucv Ls Swap Cadolet Build, long range Blazer Bash 2026 prep
- Thread starter Cucv_M1008
- Start date
Converting my M1008 from 6.2 Diesel to LQ9 power
I would like to know more
PicoScope 2000 Series USB oscilloscopes up to 100 MHz and 1 GS/s
A range of portable USB oscilloscopes that don't compromise on features. Up to 100 MHz bandwidth and 1 GS/s with 2 or 4 channels, a signal generator and optional MSO.
www.picotech.com
I have one, was not to expensive, and fast enough for most automotive stuff. I don't use it often, but when I do, it works very well and quite intuitive.
Basically a bare bones quality 2 channel oscilloscope
I've also used it to measure cycle times of relays since it is 2 channel. You can monitor the input and output at the same time.
But its not 8 or 20 channel like I used to use for diagnosing all coils and cam and crank sensors at the same time. But those cost $20K and we owned by Chrysler.
This was maybe $120 with 2 wires or something.
Will this help me figure out my Vss issue?PicoScope 2000 Series USB oscilloscopes up to 100 MHz and 1 GS/s

It will let you see the signal coming from the VSS or to the computer. If you can solve it with that info then yes.
The first time I used it, was because my speedo was not reading the output on my Holley. So I looked at the output and the speedo wasn't pulling the Holley output down close enough to ground to read it, so I added a 1K ohm pulldown resistor and it solved my problem, everything worked then.

Data logging is cool. I ran the truck around after I fixed my VSS issue and my tuner says the truck is running a little lean and he will help me tune it to make it a little better soon. he thinks its either the MAF or a Volumetric Efficiency table. I'm new to all this so I'm not sure.

I understand what lean is but I don't know enough about hp tuners to fix it.
I'm beginning to build my list of to do's for Blazer Bash. It's a big list. I'll post it tomorrow.
Meanwhile some parts arrived for the M1008. New shock mounts from ORD. One of my upgrades will be new shocks also. I want to get these powder coated instead of spray painting them.

Oof here is my list that i have come up with for what I would like to do for Blazer Bash. I have Broken it down into three category's. My goal is to try to fix one thing on the list a week. We shall see how it goes. Im also starting a parts to bring list.
Top Priority
35 spline swap
Fix VSS with switch for low range.
Tires installed
front locker
tie rod lube it
new front springs
install new brake lines
finish shifters set up. Adjust transmission shifter, connect t case shifter
I Need to do
Fix park in the 4l80 I have park
Rear leaf spring shackles
Exhaust leak, real exhaust
Power steering fluid leak at hydro boost Oil Leak off back of engine (intake manifold needs to be pulled)
Make extra reservoir for PS fluid with rad hose
Secure fuel lines from tank to fire wall Mounts Ordered Mounts suck.
Gas Tank vent (where should I place it and what are some examples)
Front wheel bearing repack
Rear brakesshoes wheel cylinders and hard wear ordered
Front shock mounts need to get powder coated
Rear flexible brake line I need to install it
Gauge Custer wire in and install.
Lube Chassis
Fire Extinguisher need to install
Fix O2 Sensor wire on passenger side and mount to fire wall New weather pack and parts here fixed enough.
Oil Leaks / any leak
Fix steering brace on cross member Cameron will fix
Sending units for water and oil.
find 37 inch spare tire
Figure out why oil pressure is lower than normal. (possible oil pan pick up tube o ring, Replace when I do cam swap and transmission pulled at same time) Looks at 5.3 in garage.... All it needed was a oil change
I Should do
Shocks rears installed
Front springs
Wire in tach
Tie rod ordered working on mock up today.
Re cover seat
Cam swap

Rear leaf spring shackles
Gas tank skin plate
Roll cage install
I would like to do
Stereo installed.
Pressure wash under side of truck

The Need to do list is the Priority. Any Suggestions would be welcome.
Parts I need to bring
Oil Filter and Oil.
Spare Alternator ordered Killed in flood, re order
Spare AN line and fittings and tools.
Fuel line adapters to AN
Spare EP381 pump and fuel line and crimps new pump needed
gear oil
RTV
Gaskets for things.
Bedding for cabin

Add an oil filter, it’s cheap insurance and doesn’t take up much room. The bb year of oil filters I just keep one just in case.
Yea we can now drive and the 4l80 shifts great. Been working with my tuner to get it tuned properly.
I was in the garage and just saw, my spares and said I need to grab one. And my spare EP381 fuel pump.
I'm going to hit up the powder coating place near me and see if they can powder coat my shock mounts like the wheels in this picture.
Prep is key, don’t be afraid to go over it. I usually pull my truck off the road july 4th and drive it a few days before loading it on the trailer. I over check every nut and bolt and race prep it.
Am I the only one who saw that and thought “I need one of whatever that is.”
No you are not.
That wasy first thought!
