MS1?

[E4ODnut]

Is anyone using MS1 with the MSnSExtra firmware to run their EFI converted engine?

Curious minds want to know - I have an MS1 setup I bought years ago that I might like to use.

My son and I are gathering parts to convert his 1600DP Street Baja. Conventional wisdom seems to recommend MS2 or MS3, but I have a fair amount of MS experience and I see no reason why MS1 couldn't do the job just as well. It needs a few hardware modifications but they are no big deal. The MSnS Extra firmware will handle waste spark, bank injection with no problem. I have a couple of MS1s left over from previous projects so I'm going to give it a shot.

If you are not worried about all the newer bells and whistles the MS1 worked perfectly fine before and can work just the same now minus "bells and whistles"

Yup, That's my point.
MS1 is now obsolete because the processor is no longer available, but for anyone who has an existing one laying around they should work just fine. I've modified my V2.2 board for a VR crank sensor, two ignition channels, a PWM Idle Air Control valve and a 12v tach out signal. I've also designed a new Aux board (relay board if you will) that incorporates the high current ignition drivers and the crank VR sensor conditioner as well as relays and fuses. I'm expecting the board to arrive from the board house in China this week. I've set up a simulator so I can check everything before we commit to installing it on the engine. We will be using all Mexican EFI (1600i) mechanical parts including OEM temperature sensors and injectors. If anyone else is interested in using MS1 I'd be happy to share information.
