Thread: Engine management system comparison.

Now I know what NismoTronic, NEMU, and TunerCode is!

About time

Let me know if there is anything else that you need help with.

BTW are the Nistune Prices USD or AUD $?

Fuck if I know.

Reason I say, prices where much higher on Nistune website. Granted PMLS probably gets a nice discount.

Here is my first crack at it:




MegaSquirt III:

Notes:
Megasquirt 3 is available as a kit you solder yourself, or prebuilt using surface mount components. There is also the MS3x (extender) which attaches to the ms3 cpu board to add more inputs and outputs. See detailed comparison:

i'd like to try out the free ems. how hard for a noob to get started? is there a pcb you can buy?

source on github with a debian repo for toolchain wow.

jasonb, thanks for the MSIII info! I'll add it ASAP.
As for FreeEMS, let me get you in contact with the main developer.

I've added MS3 to the list, and I've asked some EMS folks to help contribute first-hand knowledge of EMS systems they are familiar with so we can flesh out this list a bit more.

Adaptronic looks very impressive!

Miko has a couple 20v CAS 's for sale.
