Man I wish I had known it was more common to delete code 43 before I ordered new sensors. So this resistor you speak of is it inside the computer?

Update:
new o2s seems to have made a difference in the trims.
Now I need to resolve a code 43. I had the code turned off in the tune so I could focus on other issues the engine might have...
New O2 sensors will be here Wednesday. Will report back
Drove the car around for a little bit yesterday still need to post the logs, i always get on from my phone.
Anyways the negative trims persist. Fairly certain the rich condition is false because...
you know youre right about it still trying to read the maf, Ive had that happen on another car, I will mess with this and report back.
The maf was already descreened and I did the SD flash just...
as far as I know the trims may have always been messed up. That was the reason I converted to obd1 as Ive tuned several obd1 lt1s. Ive been using the data logs to point me to things like the...
The o2s have been like that since I bought It. I will adjust the tune for that. Kinda doubt thats causing max negative fuel trims but It cant hurt.
im trying to avoid band-aiding the problem...
Forgot to mention car has been converted to obd1 witch proper knock sensors.
I was always under the impression that when O2s fail they fail lean? Causing the pcm to add fuel (blm above 128 for safety). They are switching but they have been moved I think so may need to tune...
Background on the car its a 96 Corvette A4. When I bought it ran like it had a miss. Since then Ive found and corrected a number of problems. Removed a jet piggyback tuner pos. Ran great. Still...
Fuel pump was the culprit. I realized the issue would only occur during PE mode.
Tank was nasty mix of dirt and rust and pump was missing the sock.
New pump and filter, all is back to normal.
‘95 lt1 m6 formula longtubes and ram-air intake setup.
ive been trying to nail down an issue for the past week. When the cars cold it runs great but when it gets up to normal temps when you put...
it does the same thing with the stock tune. I will look into the ignition coil and icm.
the problem isnt long cranking times. it fires right up everytime as soon as you hit the key no problem.
my issue is that when it does fire up the first time it struggles like a slight hesitation...
Car is pretty much bone stock to my knowledge. I noticed that it has an airfoil. I've installed full length headers and egr block offs.
I've made some tuning changes here is a summary :

1995 LT1 M6 firebird formula
it’s really anemic during cranking/startup it kinda hesitates. Every other lt1 car I’ve had starts up healthy.
what tables can I tweak to try make this better?
Copy and paste from the debug:
Loading Definition DEVICE=0xF4 MSG=0x0
Loading Definition DEVICE=0xF4 MSG=0x1
Loading Definition DEVICE=0xF4 MSG=0x2
Loading Definition DEVICE=0xF4 MSG=0x3...
The files posted in that thread by 06lt4c4 are the exact ones I used.
I suspected it might be the cable. I use a moates aldl to usb with a homemade bench top harness that plugs into pcm. However...
I’ve used these sockets a handful of times. Never had any issues before and never used shims. But I will try that. I grabbed the images of here and used them before successfully perhaps someone can’t...
I had a pcm I was trying to flash, at first it would connect but When I would try to flash it, it kept doing mode 13 timeout. Research told me that it was likely bricked. So I had the pcm socketed...
Thanks I appreciate that
I thought it was odd when I saw it. 4.3 or EEX was the first thing that came to mind but the VIN pulls up a 94 Camaro
"set it to manual with the checkbox at 2026 $40 bit." Im not sure how to do...
Also too the pcm has a bin file 16209991. I check the vin on gm’s website and it said this was the correct calibration file. I couldn’t locate this cal in Steveo’s bin library and searches turned up...
I have a car with an LT1 and for whatever reason the previous owner installed a 700R4 instead of a 4L60E with it not being electronically controlled is my best bet to set .bin file as a manual?
Is there a write up for how to build a cable for these using the ftdi?
