swapping ecu's
I have asked this a few times but got no real answer. I know one problem will be the EGR system. 00Fed spec have it and the 00Cali and 01 do not. It won;t throw a CEL because its not in the ECU to begin with. If the wireing harness is the same, I don't see why it would not work. It should be like the 97-98 using 95-96 ECUs
I've looked over the wiring diagrams a bit and 2000 Cali spec-to-2001 looks identical as far as ECU pinout is concerned. Also, the ECU connectors are all the same, so it should plug right in. Once(read *IF*) the 2001 Cali-spec TS ECU was released, my next step was to attempt this. I hope someone does this anyways, just to know.
If you have a FED spec or auto, then you could have more complications like the EGR to no EGR(mentioned above) and maybe the TCM stuff...I'm not sure.

Yeah I am fed spec and auto. What could be some effects if it wasn't to work. I don't see how the TCM would effect anything cause isn't the anniversary was the only one with a different tranny.
What wasn't to work? EGR system?
TCM just means more wires, since the ECU and TCM are interconnected. Might be plug-n-play also, I haven't looked at the schematic for autos though.
I'm sure there will be some differences, ie NOT just 100% P-N-P, however all the "critical" stuff the FSM shows seems to match between the 2000 Cali and 2001s.

Depends on what isn't compatible/complete.
The car could start, but just throw codes or idle rough or possibly go into limp mode or just run like crap since it's fuel/timing maps are for an EGR setup, I don't know.

Just to put another idea out there, I was thinking, for 2000/2001 people interested in doing 3.5 swaps couldn't TS essentially put the 3.5 maps onto the 2k1 ECU and tweak it accordingly? I spoke with Brian at TS a while ago about the possibility of them tuning a 5.0 gen with a 3.5l hybrid (3.0 timing chain/oil pan, intake/headers/exhaust, etc). My idea was to reflash the 2k1 ECU with their current 3.5/headers program and tune it to accommodate for the lack of VTC. Brian said it should work in theory, but he would have to talk to Tedeshi (sp) about it. I haven’t followed up on this yet but I thought it was worth mentioning. Can anyone here come up with a reason this wont work?
i have been wondering the same thing for a while and i seee that there is a lot of emphasis on whether the car is fed or cali and i dont know which mine is, can anyone tell me how to figure it out. Also if i am reading right the cali 00 and 01 are the same ecu? Do i have that right. Cuase if i can use a 2k1 ecu i am down to try it and see what happens.
