No but I might use an economy mode.
Just not convinced your Megasquirt one is for me.
It probably isn't if you're not that way inclined.
You don't need switcable maps just for economy on a SEM because you can map the cruise areas to give you best economy if you like.
You can adjust fuel to run leaner at light cruise at 50,60 or 70mph but be richer in power areas when you put your foot down.
tshirt2k gave good advice here.
With alpha/N for throttle bodies the high TPS regions e.g. 60% to 85%+ deal with high load / WOT.
Low TPS values are part load / cruising.
This is the same on a speed density system using a MAP sensor, but the TPS value is replaced by MAP.
The only reason to have switchable maps IMO is for 95RON & Super unleaded 97/98/99RON
You see I have no idea wtf you are on about!
So I am going to plug into the ECU and play with such things?
Exactly why you should do some research on forums where there is lots of info on such things.
You need to know the effect of what you are planning. Then decide if its worth the cost.
You also need to know what CR you want to run and how you are going to achieve it. Skimming head, block, or getting pistons. Each will have different costings.
I wouldn't be undertaking such a job and have no knowledge/idea of what it entails.
IMO You
need to know wtf he is on about or you will be throwing money down the drain.
As I've said before, you can get 175ish hp from decent mapping on a standard block and head.
Save yourself hassle and money by changing crank and machine pistons to give ~11.2:1
You couldn't go wrong by contactinh Hotgolf. I think he is on here. He has built a few and knows alot on this whether it'll be new pistons or not.
Re emissions. Have you not thought about fixing the problem? because an engine in good order should pass fine.
