Can I Actually Purchase This 3.0 IHI?

@Hatermkr for the Win as always 💪

Not really just know a guy that happens to know a car

The flex sensor will have to feed something in the computer. That is likely a physical wire going from the sensor to a pin on the ECM. THEN the tuning would have to be in place to understand that data.

 

[Unholy707]

Yeah, no way it’ll work with a non 170. But I still want to see it to get some ideas. There are ways to bench flash the calibrations with your vin, and replace the wire harnesses.

From what I understand, that's exactly how Satera does it--with non 170s--all in the ECM tune and a sensor pinned into it somewhere.

The pin in the ECM likely already exists and is just un-used. Run a wire from the senor, pin it, enable it, flash it. Easier said than done but I imagine that's how it goes. When 170 repair and wiring data is available we'll be able to see how it's hooked up.

I know exs

I know exactly how they do it, and it’s not right. I figured it out. They enable the exhaust recirculation valve in the pcm (6.2 doesn’t have it), run a wire from the flex fuel sensor to that pin on the pcm (same pcm between 6.4/6.2) rescale the sensor and voltage to mean a specific e%, and then modify the exhaust recirculation tables. Which don’t have cold start tables, and a lot of others. It’s a good try, but all the tables aren’t there to make it work 100% the way it should

 

[Unholy707]

I’ve been there, done that, got the t shirt. Definitely easier said than done, but I guarantee you it will need the 170 calibration bench flashed to your pcm with your vin. Also, new PCMs aren’t the gpec 2a.

[Unholy707]

This isn’t a platform or PCM that ever had a physical flex fuel sensor until now, this isn’t a GM

 

[Unholy707]

Closest thing was the old dodge daytona that ran on methanol with a physical methanol sensor. I have that calibration and have decompiled it, and from what I can see none of that exists (as legacy code) in this platform

 

[Unholy707]

They also reconfigure the BCM and use the ambient air temp sensor to display the “e” % on uconnect. I haven’t dug too far into that part but I know how to do it

 

[Speedy!]

What ECM is being used? I hadn't heard of an update since 2018.

This is how you add flex fuel to my Z06. Add a wire from sensor to pin 39 on the ecm. Change one thing in the tune wam you have flex fuel.

Yep, because you can patch the GM pcms with ones that had the actual sensors. FCA never had that

hey never did flex on a vette? Unless I’m loss on what your saying.

 

[Unholy707]

No they did flex on other GM vehicles pcms. HP tuners patches the OS with that of a GM vehicle that did use it. Dodge/chrysler never had a physical flex fuel sensor car until now that shares similar PCM architecture, which is why we don’t have it but we have the inferred flex fuel because it exists in the 6 cyl flex fuel cars

[Unholy707]

Hp tuners allows custom OSs for GM PCMs, patched with the OS from GM cars that did have the physical sensor

 

[Unholy707]

HP tuners won/lost a lawsuit brought by FCA for right to repair. They won saying they can modify the calibration, because the vehicle owner technically owns the calibration which is covered under right to repair. The underlying OS code was ruled proprietary/owned by FCA, thus not covered under right to repair. So I wouldn’t count on seeing anything ported over from the 170 via hptuners like they do for GM unless it already exists in the OS, which it won’t because it didn’t exist until now

 

[Unholy707]

Hopefully that makes sense. I did extensive research and r&d on this for a long time

 

[Hatermkr]

Yes it does. I run my challenger on e all the time. My z06 also and next will be my c8. I have stations all would me with it.
my GNX has been on e from 2006

 

[Unholy707]

Same, as long as you’re not going all out e65-75 Is all you need. I have 2 tunes, no big deal. Realized it was a pipe dream, and now dodge actually has it in the os, which is why I’m eager to see how it works and if HP tuners even has the tables for it specd out yet. If you can scale the voltage, you might be able to bench flash your pcm (year dependent) with the 170 os and your vin, pin an off the shelf flex fuel sensor in and change the scale of the voltage in the tune. But this isn’t something that just anyone will be able to do with any tuner, will 100% need to be bench flashed. Unless hp tuners uncovers it existed in the old OSs all along, but I highly, highly doubt that
