This is one solution for adding a sensor or relocating the sensor for the gauge. Given, the ECM will give a temp readout on the hand held programmer and has the ability to control an electric fan.

Thanks, that’s a great solution.

I can relocate the temp sensor for the gauge to the thermostat housing and put the EFI coolant temp sensor in the head.

I'm pulling for you.

I spend way too much time on the gm tech forum (of which I I am one, for a while longer anyway!), don't think I brag about that system over there!
Many AMF/ DOD lifers fail before the 1'st oil change. Wound seem to be a manufacturing issue as failure rate much lower from 2017 to around 2020.

I seem to remember another Rube Goldberg project from the 1980's- - - -the Cadillac V8-6-4. A bunch of train drivers thought that was a good idea, too! How about the mid-1970's Vega high-silicon aluminum cylinder block with the acid-etched cylinder walls and the cast iron plated pistons? I made a bunch of money installing flanged cast iron sleeves and conventional pistons in those things!
LOL!

You have 2 sensors above the throttle plate in your image.

One looks like an IAT and the other looks like a standard GM MAP sensor, but MAP is generally measured between the throttle plate and the cylinders.

What are those sensors?

My design is relative to magnetics and component weldability related to the GM GDI pump fill valve. Prior designs were bolted on and newer designs are laser welded. I dealt with the design flaws that were involved with welding 420 stainless steel to 17-4 (and 420 to 420). Redesign of the valve body allowed to welding 17-4 to 17-4 (no issues with root cracking, much easier to weld).


IAT sensor and AP are both above the throttle plate. The throttle body on my base system has the MAP above throttle valve, so I carried it over. Referencing it after throttle plate isn't an issue as it can be plumbed to do this.

rhussjr Do you do any tturbo work,an advisor said not to try for economy with turbos,do them for power. Turbo-cummins does both !! Maybe they have a bigger engineering departmennt the we are used to !!

Thank you for sharing this project. Please continue to do so.

I have been doing turbos for the past 25+ years in VW and diesel applications. One project was a compound turbo on a VW TDI that made mad torque. For gas applications, I did a VR6 with 617hp / 513lbft to the wheels back in the late 90's early 00's. You can do turbo for economy, but given most do for power as it is the main purpose as a power adder. Low boost for additional power and torque on a stovebolt (or any other motor) can be had with the right setup.
