MS2 vs. MS2 Extra- What's the diff?

[macambra]

I am in the process of building my MS2 pcb, and I am confused after reading everything I could find. What's the difference between MS2 and the MS2 Extra? I have read both manuals (pcb build chapter), and they are slightly different. Which manual should I use?

 

I have an 83 ZXT. I want to use the MS2 to control fuel, ignition, boost, and cooling fan. I have almost completed assembling my PCB (following the MSextra manual), but I'm concerned I'm going the wrong direction.

 

Yes, I have searched. I get too many MS2 results to weed through.

 

Any help here would be apreciated.

The extra code simply has more features and is really the standard as far as what most use. There are no PCB differences, just finish building it, download the extra code, and follow the directions.

Like letitsnow said, extra has more features like nos, flatshift/launch, boost control, different types of rev limiting, and the biggest thing is bigger tables 16x16 like the ms3 daughtercard. You can do 4 banger sequential and 8 banger semisequential too. I was gonna run it but I couldnt get my trigger to sync up. I would recommend using a standalone boost controller if I were you though unless you can risk blowing your motor up as it has very limited field testing (just saying this because I havent found alot of writeups on this). They are beta testing mobisquirt for your iphone too and they use the extra code for testing so just another thing to think about, wireless datalogging from your iphone!
