    Went from MS1 chip with some issues with electronic noise issues and resets to the MS2 board which fixed all my issues. Way better! Thank you Matt.

    Watch the pins on this guy. During assembly process I removed the chip board per the asm manual and broke two pins. Not real happy about it – very expensive mistake. I have removed other eproms for rechipped engine and trans ECUs and this is the first time one has broken on me. When seated it is very well secured but if you have to remove it be very very careful. When if finally broke loose the last two pins broke at the opposite end I was prying on. Fortunately the pins did not break off in the eprom reciever. It could be worse but again, not real happy about this.

    This is an AMAZING processor! If you have a megasquirt 1 like I do, this board is a must for tuning and resolution!

What firmware is on this daughter card?

  • This processor ships without full firmware. It has the bootloader installed so you can easily load any MS2 code to it.

Can I order this pre-loaded with firmware?

  • We do not offer it with firmware as it is much easier to load firmware once this card is installed in a MegaSquirt ECU. Once you have it installed, you can easily load firmware using a laptop.
