Megasquirt Advice and discussion.

Wow! The Motec has come a long way.

I worked with one about 10 years ago and it was very comparable to my modern Haltech (that was before widebands were common). I guess I should have expected that they would come as far as the Haltech (although that DOS software is still awesome).

Point conceded - not all ECUs are created equal. Even my e8 has many more features than the old e6x (like autotune, desired lambda maps, VE charts, etc.). However, it was all these cool features that enabled me to trade my e6x for it, because extra features and functionality often makes an ECU harder to configure (Obviously not so with Motec).

Actually, a decent tune can be achieved using a megasquirt V2 in about 45 minutes of street driving. Autotune can take it from there. What is important is the coolant correction and air temperature correction (you should be careful where the IAT sensor is located).

Either way, I will still argue that the overwhelming majority of the effort in installing an aftermarket ECU is the wiring and initial software setup. The rest is cake.
