If you post your .msq (tune file), we can take a look at it and perhaps offer some comments.

I use the last one I dont know how else to post it. Thank you so much for trying to help. Tony

The .msq you posted has absolutely nothing to do with the bike you're operating - 350cid, 8 cyl 4-stroke?!

If you can post that one, you can post the real one - try again, please...

Ok so I spent some time reading and searching old post on 2 strokes and I went into other trables and changed the alpha-n-map settings and now it wont even start I still have spark and tried starting fluid and nothing happens. Please help me I don't know what to do next. Thanks, Tony

We can't help you unless we have an msq. If you are in fact using the msq you posted and that is for an 8 cylinder, of course it won't run a 2 cylinder, and that would explain your problems. Have you gone through all the settings in Megatune or Tuner Studio and changed them as needed to fit your engine ? If you have then what you have to do is save this as a new file, call it whatever you want. You do this from the file option in MT/ TS, which allows you to pick the name and place where you want the file to go. Then you post this file the same as you did your last file.

Ok I had a friend come over and show me how to get the file I'm using loaded on here. So this is the file thats loaded it will not rpm over 300 on my racepak and the laptop show 900 rpm on the screen. Any help would be appreciated.

Thanks, Tony

There's an error on the very first tab - 'Fuel Set-up / General' shows engine displacement as 60cid, or 938cc. I don't think this matters. What I DO see as an issue is in the 'Fuel Set-up / Injection Control / Required Fuel'; you have a 2-cyl 350cc 2-stroke, but you are using 30cc/min injectors. These are TINY, and are giving a HUGE req_fuel number - 33msec! Are you sure those aren't 30lb/hr? That give a much smaller req_fuel of 1.9, or slightly less than 1/16 of your current number. Check your injector values, and check your entries.

I'm sorry I never posted the project It is a 1000cc 2 stroke 2 cylinder snowmobile, it's a 36-2 wheel and it has 1 injector per cylinder in the throttle boddies. I changed it from a dual coil set up with a single lead to a single coil with dual leads and changed the program to no dual spark and the fuel got alot better but it still wont rev up past 300 rpm on my racepak and 900 on my laptaop. Thank you for trying to help me I really appreciate it. Also do you know were I can find out the specs on the injectors.
