I have a new set up on my hot rod and I am also new to all this but so far having fun. not sure if this is the correct place to post his cond. but here goes. I have set up a 350 chevy with a 6-71 blower that has been using 2 600 holleys and now has been set up with 3 2.5 throttle bodys from a 4.3 v6 chevy along with a plate holding 8 56Ib. injectors the fuel rail runs around the outside of the plate. I am currently using a ms1 2.2 just to see if I could make this work. the engine stars and runs and you can drive it runs good when I try to go above 4000 rpm it wants to shut off some times it will stall but restarts. I checked fuel pressure ok. I could not get it started with tuner studio had togo back to megatune and install bg original code engine started right up I tried using autotune from tunerstudio can I use this with ms1 2.2 I know this is the cheapest ms . I just wanted to see if it worked. any help would be appreciated. thanks ED

Can you post your .msq tune file and a datalog of the engine shutting off at 4k? Are you using a WBO2 sensor?

Yes I have a wide band o2 lc-1 I will send you the logs soon. engine would not restart last night no matter which download I used from tunerstudio as soon as I downloaded from megatune it started could this problem be my cable from the controller to my lap top. I have to use a usb to db9 adapter cable ?

found the problem, the engine was getting way to much air I had to really richen it up to compensate I found it by disconnecting one of the three throttle bodys and the engine rev. fine accually ran very well. I went into the ve table and had to adjust it. I may end up using just two throttle bodys. as it just has way to much power for the street. the car weighs only 2100Ib. Thanks for the interest. maybe someone out there has a similar set up
