Did anyone have the Blue 71 pin on the PCM programmed to "tow haul mode" or what I would call "Land Rover Sport Mode"?
I think that pin could be easily used to function with the sport mode of the LandRover which in my case now appears to do nothing. I would like to do a little towing with it and I figure sport mode would have been the closest thing.
So it might be possible to simply connect that sport switch on the rover to the GM PCM and have it work.
Thoughts?

Probably not since the LT1 and earlier small block have a longer crank than most LS engines. And then also the electrical is all different.

What are everyone's engine temps after completing the swap? I'm running around 195 to 199 while moving, but if I let my truck idle for a decent amount of time, it slowly creeps up to 218, maybe higher if I let it continue. This was with outside temps around 100 degrees. Anyone else seeing this? I believe the GM engine may run a bit warmer but a 20 degree swing seems like a lot.

These came from a junkyard in Lakeland -- very nice and friendly people. It was our first time using them, but seeing as how things turned out, we're planning on using them in the future. They had about 20+ LS engines ready to go and said that they could do the full dropouts with the computer/harness/etc if we needed them for a competitive price. I'll forward along the contact info if you send me an email.

The sport mode on the Land Rover changes the transmission shift points for the ZF. I noticed subtle differences with sport mode on. The GM ECM "tow haul mode" I think only affects transmission shifting tables for the GM ECM. Since those aren't used, it wouldn't change anything.

Hi Ace, I just got a great deal on an 04 Disco 2 with overheating issues and most likely needs a new engine. I am reading through this thread because I will be doing an LS swap (kinda planned on it when I bought the rig) and I am currently on post 295 so I still have a lot more to read but I saw you mentioned this place in Lakeland and even though I live in NC my best friend lives in Lakeland and I go down there once a month. Do you know if they still drop full engines? Like I said I still have alot of reading to do and I might be getting ahead of myself by posting now but I really want the swap to be as easy as possible since it will be my first. Thank you and I am sure I will have more questions as I get this project going, you are awesome for doing this!
