A quick overview of a 1999 GMT400 platform LS swap. The spider injection vortec engines share a lot of functionality with the 99-02 LS truck platform so you can make cruise, abs, ac and gauges work like factory.

How u get fuel gauge to work correctly

@HsPerformanceWi 11 дней назад

Hptuners, the ecm processes the signal from the fuel gauge and sends it via PWM to the cluster. Copy over the parameters from the original vortec black box ecm to the P01 under the fuel system tab

@lit549 5 месяцев назад

So on the AC, it all was possible cause you run a mechanical fan? I'm running dual gm electric fans and I'm having a hard time getting the AC to work right.

@HsPerformanceWi 5 месяцев назад

LS1tech.com has a few threads on making it work, the ecm needs to see the ac pressure via the factory sensors

I have 2000 k3500 5.7 with a 4l80e. Will that trans work with a 6.0? Or will i have to get one from an ls?

@HsPerformanceWi 6 месяцев назад

all 4l80e's will work with a 6.0l. Early ones had both cooler lines up front, 1997 and up 4L80E's are all the same. The only thing different between sbc and LS versions is the converter shield

@collinwilliams5420 6 месяцев назад

@HsPerformanceWi sweet so my 2000 sbc 4l80e would bolt up and work with the 6.0 wiring and ecu ect? Everyone is telling me I had to get a ls specific 4l80e since my sbc trans wouldn't working with ls wiring and computer.

@HsPerformanceWi 6 месяцев назад

I don't know where you are getting your info, but this is fairly basic common knowledge in the gmt world. 4L80E's from 1997 up to when they stopped making them in 2013 are all the same

What alternator did u use for the bracket

@HsPerformanceWi 6 месяцев назад

bracket is in the description, alternator is stock from the truck

@jaydub3769 6 месяцев назад

Just to clarify the alternator off of the 5.7 right?

@HsPerformanceWi 6 месяцев назад

@jaydub3769 correct. Either the 5.7 or the 6.0L alternator will work, but the one from the 6.0L was a larger framed 145 amp unit and the AC line was a bit stretched around it and we opted for the smaller one

Holy cow! Looks like a factory OEM install! Amazing work, sir! What's it cost for you to do this? How much was customer billed? How much time did it take to do this?
