when you start to increase cyl pressures, run E85, and push the limits, I'd rather have a more advanced engine management system than what GM did back in the 80s



Nothing wrong with it, but it's not up to par with current technology on many levels.


the stock system has been proven to support up to 700 hp and works just fine up to that and beyond.


but there are NO safeguards on par with what the MS3 pro or other systems or advanced individual cyl tuning like aftermarket systems have the ability to do. Integration will be a huge PITA and indeed NOT worth it to most. for normally aspirated, clearly gains would be not worth the squeeze.



Tuning with the stock stuff is not a limiting factor until you get to the limits which are beyond where most have been.


Thanks for your thoughts.

The thread is a little convoluted with the number of questions.

The only thing I was responding to with my last response was: "I would still like to quantify if there is anything to be gained w CnP on an LT5 w typical mods, ie cams, porting exhaust."

And the short answer is still no. E85, alternative fuels, boost, and altered architecture are not "typical mods" in the LT5 world.

I'm running my 1990 on an ms3pro. There is no need to replace the DIS and stock coils to do any of the things you listed aside from individual cylinder tuning, which for this engine will gain you little to nothing.

That's not to say you shouldn't do it, but it would be one of those things to do just because you could, not because of measurable benefits.
