These are the RED & BLUE PCM connector pinouts that will cover 1999 to 2002 4.8/5.3/6.0. Your harness MAY NOT have a pin in a location I have listed having a wire. I have tried to list all possible wires that will show up 99-02. If I show a wire, and your harness does not have it, you probably don't need it anyway.

2021年11月13日 · Here is one I made by combining a bin with a 2004 Express Van 4.8/4L80E and 2004 2500HD 6.0 LQ4/4L80E. I took the engine calibration and engine diagnostics segments and swapped them to the van file. Hopefully it will work.

2018年2月1日 · Find key specs on GM's LQ4 6.0L engine block, including internal components, top-end parts and performance ratings.

I picked up an LQ4 with 317 heads and a pcm from a different vehicle with a 5.7. Ive removed vats, EGR and rear o2's and changed engine to 6.0L. I have been unsuccessful in starting and am curious if it is due to the current tune. i followed a few different guides, but would love to see if anyone could steer me in the right direction.

The Vortec 6.0L V8 (LQ4) uses advanced technologies including aluminum cylinder heads and a thermoplastic intake manifold. Its deep-skirt engine block allows cross-bolting of the bearing caps, limiting crank flex, stiffening the engine's structure and reducing overall vibration.

2017年11月20日 · Changing your driving style, re-gearing to better highway gears or removing un sprung weight (aftermarket wheels and tires) is the best way to try and gain mpg's. 2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy. If you don't post your tune and logs when you have questions you aren't helping yourself.

2015年5月8日 · Running a NA LQ4 with a Holley mid rise. The Holley intake only works with the LS3 sensor for the bolt through mount. I have both the LQ4 and LS3 map sensors. Aside from wiring what is required in the tune to get the ls3 sensor to jive with my LQ4 tune? I have never converted a map signal before which is why I'm asking.

2025年3月16日 · I had something similar happen when I swapped an LQ4 into a manual transmission vehicle. Sorry its a bit foggy, but IIRC, in HP Tuners, System->Vehicle->System Options shows a table of various settings for the selected Platform Type. When I switched it to a manual trans, the Column for "ETC" was set to "0" (Disabled).
