Can someone help me identify this megasquirt????
 

Can someone help me identify this MS, I believe it is a MS1. Correct me if I'm wrong thanks.

megasquirt 1 processor, 3.0 board.

Is it worth it to upgrade the processor to MS2 or just sell it?

Sell it, converting to MS2 or MS3 requires hardware changes inside, at which point if it doesn't work the seller will take it back as it's modified, and you'll be out the MS1 + MS2 money.

How much these in the used market? If I want to keep it and run it with my turbo set up would it be ok?

It should run your turbo car just fine, but MS2/3 are leaps and bounds ahead especially in terms of driveabllity, I/O, Logging, the list goes on.

Since you already have it, your costs are sunk, so If I were you I'd just run it until you determine it no longer meets your needs

Thanks everyone for the feedbacks

One more question how can I figure out what year this unit will work with?

90-97 NA only.
