so I am planning on building my Megasquirt with diyautotune. I just don’t know what mega squirt to go with I have a 95 1.8 I’m not going to be running a lot of boost So should I go pick out Megasquirt 3 or 2 or get pnp. Price doesn’t really matter so I’m just trying to figure out which one will be best with my set up

 

MS3 PNP Pro is the best. All others are compromises, but may be the right choice if you don't want to pony up the cash. Figure out your budget and if the features of the higher end ECU's are worth it. From personal experience, just the driveability of MS3>MS2 is worth it. I think it's also worth having either MS3pro or PNP Pro over the DIY style, from a reliability standpoint.

 

Any of them will make power. Paying more gets you an easier tuning experience, more expandability, and safer operating.

 

Follow my guides. if for some reason you happen to do MS2, buy the DIYPNP.

if price doesn't matter picking ms2 makes little to no sense.
