Scratch that thought, they are plugged in correctly.

I can?t get a useful scan. I?ve had this recurring issue where the scanner stops recording or showing any live data beyond about 3 seconds...

Just had a thought... if I got my front and rear speed sensor plugs reversed, would this issue be a possible result?

So when I shift manually the trans is great, no slipping or odd noises. Does this point toward solely the speed input sensors or could it still be something else?

To be specific, when in D and...

That?s my mistake. I was told it was from an ?01 but that tune is the one I pulled from the ecu that came with it.

I went out to record a log but it started snowing so I'll try to get one tomorrow.

Went for a drive tonight after doing the segment swap and verifying the reared ratio was correct but it's still doing the same thing.

As soon as I take off at gradual throttle, it instantly shifts...

This is a 5.3 from an '01 Silverado which originally had a 4l60 but during my swap I moved to a 4l80e from a vehicle I drove a handful of times and the trans functioned perfectly.

Since getting...

It?s currently at 14.9-ish. I was hoping for a little more because I really don?t want to have to add an electric pump/canister for my brakes to be good.

This ended up being me accidentally swapping the o2 sensor plugs... DOH!!

So this is a '01 5.3 Swap in a '54 Chevy Suburban. it's got the most mild cam Summit offers, the one that requires no valve train changes...

I had it running totally normal during mockup of the...

Injectors arrived today and I'm finally running stoich (imagine that, 2 cylinders of no fuel = Lean :banghead:) and ready to start tuning. Thank you 5FDP.

o2's arrived today and they had the additional ground wire to the body of the sensor unlike the cheap eBay sensors, which I assumed was good . Wire colors were different than eBay colors which I...

Ok appreciate that info.

I got a little progress after work tonight and pulled the fuel rail and injectors to test spray. I have two completely dead injectors. 🤦🏻*♂️

I have another complete...

Gotcha. I have Delco sensors arriving tomorrow. Assuming they clear up that issue, would these be too much injector for my setup?
...

I verified my o2 Sensors are heating but I'm confused by how the Scanner is showing their presence.
My PCM pinout states the wires I utilized for the o2 sensors are for Bank 1 Sensor 1 and Bank 2...

This has also been curious to me, of all the scans I've run during this, both o2 readings have remained not stagnant (they do fluctuate nearly imperceptibly) but not near what looks like a legitimate...

Ok been trying to gather as much info as possible before creating this post in search of some help.
Go easy on me.

'02 5.3LS full rebuild. Only mods are the most mild Summit cam that doesn't...
