Does a different cam need an ECU replacement as well?

Hi everyone,

 

I am having an L28ET made at a shop with a custom grind cam and some head porting and I plan on installing it into my stock 280Z.  The plan was to have the L28ET powered by megasquirt but I am worrying about the break in period with the new engine.  I don't have megasquirt installed yet and don't like the idea of  trying to start a new engine with Megasquirt.

 

So here is my plan and please let me know if it will work for the break in period or not.  What I want to do is take this new L28ET and switch the block with my L28E, get it started and running properly with the L28E.  Once that phase is done, add megasquirt and put the turbo components back on.

 

I don't know the cam specs off the top of my head and I am thinking the turbo distributor, custom cam, and ported head might be problematic with my NA ECU.

 

Will my plan work?  If not, what do you recommend?

I can't say with 100% certainty and this thread is a bit stale so maybe you've gone for it already, but yes you will likely have running issues with the stock ECU. It might run and drive but not like it should and definitely wouldn't be taking advantage of the cam.
