So it is possible to use an 02 operating system in the 99-01 pcm??? I really need to learn more about and get a tuning program and start playing with it.... I was told you couldnt force an 02 os into a 99 pcm or that you couldnt program an 02 pcm with a 99 vin.. Arent the pcms the same other than the os??
EFI Live works differently for that.
There are some minor changes in the OS that have to be addressed but it does work.
I highly recommend you buy your own software. Even if you don't learn to fully tune. You can still go back and make minor changes that will better suite your driving habits. You can also work with a tuner when you have your own software.

If you know what your tuner uses that would also be an indication of what you might want.
I think SDPC has a few nice package deals on HP tuners with a Wide band.
I believe there both price controlled for resale. Both will get the job done, Its more a matter of preference for most people.
Look it over and ask questions before you make a decision.

Fairly certain my tuner uses hptuners... He also sells the software.... Want to see if they have a demo on the main site for hptuners and efilive.... Be nice to be able to change my shift points now that ive replaced my converter...without a 2 hour ride....

If he has HP tuners you can email back and forth with logs and he can make adjustments based on your feedback and email you back.
You will also be able to make small adjustments to things like shift points and so on and tweak it to your liking.

Yes,
As noted earlier in this thread the Oil pressure senor is different, 1 wire Vs. the later 3 wire design, so you will need to swap that. Be careful as it's not un-common for those to break. The plastic on top is brittle and can be easily damaged if your not careful
I did this exact swap for a buddy of mine and we broke his. Had to go to the Parts store and get a new one.
Any tuner can re-tune your PCM with LQ9 parameters. I also recommend using a 2002 operating system as there are a few more tables from the 99. Also If you decide to Run E-fans later it will be an easier swap. Some of the 99-01 operating systems don't function correctly for E fans.
We used an 02 Operating System on my buddies truck and everything functions correctly.
You will have less electrical head aches with DBC.
Just remember this... KISS=Keep It Simple Stupid.
