94 F-body LT1 solving problems/tune

its normal for it to leak a bit there. it looks like you haven't adjusted your idle screw. make sure your throttle plates are closed as much as possible (just not so much that they jam in the bore). after doing all this, pull your PCM BAT fuse for a bit just to make sure ecm memory is clear.

Now tps is 0. Strange. I did nothing about adjusting that screw. Rmp just raised and thats it. 700. Then 800 in a week. Then 900 and so on

Idle iac is 40 steps. Is it okay?
Idle is 850.

I'll try to install new tps. I dont like how it operates

Faulty tps.
Fixed.

Today was a next step with my pontiac
I made mods with ECM.
Installed EEPROM sockets for both sides. I want to say that there is no need in installing credit card pices. And no need to cut the bottom in a socket.
All you need is heated table and heatgun.
If you dont have a heated table you just can use household iron and a paper towel as a spacer.
Everything works perfect.

then I made some "cosmetic" mods:
1. Cat potection disable. I have cat delete.
2. Lowered the overheat enrichment protection
3. Lowered BLM Hysteresis for more accurate idle
4. AC clutch disable within lower TPS

5. Disabled AIR PUMP - DOESNT WORK!!! AIR pump still engages on start. And I see in logs. How to finally disable it?

6.Lower TEMP fans kicking.
7.Lowered IDLE to 500. Works perfect.

5. DISABLE AIRpump
Besides clicking OFF at least two switches / flags, you must ALSO raise the Min Coolant Temp to Enable AIRpump to well over 117.5°C / 243.5°F.

Generally speaking, if you want to disable anything, you often need to take more than one step, possibly two or three or more to do so.

To wit:
1. I think Catalytic Protection can be disabled with only one constant, but just in case, I'd adjust four, as GM did.

AIR pump done.

Regarding CAT protection
Factory Cat protect AFR is 12.2. Is it bad for the whole engine cooling? And what about torque? I know that it raises a little when it goes to rich. Just about 11.8-12.8

There are Low/High boundaries and Low/Mid/High Pressure parameter. Should i mod them and to what values?

Is it good idea to disable cat protection? Or it's good to leave it alone? If only I'm right in everything that I said above.
I remind that I've deleted CAT.

i honestly don't see much point in cat protect mode even with a cat, but if you have no cat, there's definitely no reason to leave it enabled

GM uses the following values for vehicles that were never equipped with catalytic converters:

Min Coolant Temp for CAT Protect = 150°C
CAT OverTemp Threshold (Low Baro) = 1065°C
CAT OverTemp Threshold (Mid Baro) = 1065°C
CAT OverTemp Threshold (High Baro) = 1065°C
CAT OverTemp Air Fuel Ratio = 12.2 AFR

(Although I'd raise the CAT OverTemp Air Fuel Ratio to 14.7 AFR without any fear.)
