So ,

I just inherented a 4.8 and a 6.0 LS engine , both warranty takeouts , basically they both are complete engines with low miles (less than 20K each) .

I will have to get intakes, coil setups , and accessory drives for them if and when I use them but I think that will be a day of junkyard hopping . I would like to stay cable throttle if it is possible .

I am new entirely to OBDII and have no clue what i will need to run and tune these , what PCM , what harness is the best , what tuning software , interface , etc.....

Anyone who has any information to share on the LS swaps and the PCM deal to control it would be greatly appreciated .

I hate to have to do the Painless or other aftermarket harness' and quite frankly I would love to mod an OEM harness myself so i become firmiliar with them .

Sorry for the vauge post , but as I said , I have never messed with the engine control side of the LS engine , just looking for some input.

Thanks

TOM
