I've always been keen on the MS ECU but becoming keener with some added cams. A little about the car...
N6CE (Eunos), HKS Cams 264@8.73mm lift, CAI, 4-1 headers, 2\" mandrel stainless exhaust, Tein SS, Whiteline sways, Jaycar DFA...
Now that the cams are in I'm interested in controlling both fuel and timing to get the best from the goodies. My questions regarding the MS....
1. How is MS1 V3.0 different from the MSPNP? is MSPNP simply = MS1V3.0 + PNP MX5 Socket + MX5 Map ? anything else, relay boards etc?
2. Once I have MS, all I need is IAT to remove stock NA AFM?
3. Can MS run close loop (with feedback from O2 sensors), can MS use narrow band O2 in close loop
4. Are there significant advantages in going for MS2?
Soldering and testing is part of my everyday so that's not an issue, I also have a few NA ECU laying around so salvaging sockets isn't the issues either. The real issue is trying to take $700 out of the bank without alarming the other half

I'm leaning towards MS1V3 given the above, but what do you guy recon? MSPNP, MS1V3 or MS2V3, is it worth spend extra for MS2V3 or even the full PNP version at 3x price.
Cheers
