62mm throttle body

WHAAAAAAA!? I didn't even know they made one... Good lord... Now I am considering this swap even more knowing this.
Actually there are quite a few companies making harnesses. Tell them the setup info and get a harness AND most also will tune your ECM for you. Best source for this specific kind of information is Pirate 4x4 —-If you can put up with condescending BS.
The codes were all over the place mostly due to emissions related stuff. However the ECM that came on the donor truck was a E78. That would not work with the tach stuff from Novak. They sourced and tuned a E38. There in laid the problems. The older E38 had a software change some where around 2012 and the used E38 they had didn't have new software..........................My rig now thinks it is a 1 ton Chevy van iIts a long and expensive story so the short of it is this was one of the first Gen IV engines with a 6L90 that Novak had done. We all had a learning experience.
Now it just keeps throwing a 150A code. No where can I find what the A in the code designates!

Man nothing is simple any more. I long for the days when I had my '57 Chevy... no computer and probably 5-6 wires to reconnect to get it running and that was about it.

Too true. Additionally, if you're pulling more air, the only way to get more fuel is to remap your ECM.
..aaand, I don't think that the ECM for Jeep motors are re-mappable. (Is that even a word?)
The engine is only going to consume as much air as the engine's cubic displacement can pump. Making more air available isn't going to do a thing since the OE air intake can already provide more than the engine can consume. That's not a rumor, it's fact. The only way to get the engine to pump more air and fuel through is via a supercharger or turbocharger.
Only if the air intake is restrictive to begin with will opening it up more make the engine run better. And while many vehicles do indeed have restrictive air intakes, the TJ's is not restrictive in the least. The lead Jeep engineer, Jim Repp, even confirmed that was one of the design requirements for the TJ.

True fact Jerry, even the stock air filter is not restrictive to air flow, and works way better at taking engine destroying crud out of the intake charge than any aftermarket filter that I've heard of. (that includes water from fording) You really have to love it when the design engineers understand their customer's requirements. I wonder how many of the folks that worked on the TJ off-roaded YJ's and CJ's? I bet there was more than one.
ECM and PCM are just different terms for the same thing... the computer. Engine control module or powertrain control module. PCM is probably more commonly used when it's also controlling an automatic transmission.
I dunno, I had no idea what the rhetorical part was doing mixed up with that question so I just answered what I thought was a legit question.

Ok, ok. I lost the funny part of this thread. My 05 manual tranny has(d) a PCM with three ports. The Automatic versions have a PCM with 4 ports.
Now my V8 jeep still has a PCM (power control module) with three ports it runs stuff like gauges, speedo, 4x4 on, lockers engaged, seat belts.etc. I also have ECM (engine control module) but the TCM in intrinsical to it. So all the engine, tranny stuff is controlled by it.

I've posted over there before. Should have just called the vendor first because I wound up calling the vendor later anyway.
