do you not have some copper desoldering wire? run to radio shack and ghrab a roll $3-4.
lay it on the legs of the transitors, press your tip onto of it and heat that **** up, you'll mop all the solder right up like water with a sponge.
if you're never going to use low ohm injectors, you can skip building the pwm flyback circuit and jump R37 and R38.
hell, bridge the connections temporarily and see if that solves the communication issue.

it is Q14 and Q15. The problem is I have them out, but the little holes are still bridged even when there is no solder, I think I messed up the bord in that area. Im checking if they are bridged with an ohm meter, when they are bridged it reads 0 ohms.
Can I leave out Q14 and 15? I only plan to use high imp. injectors. What if the 3 little pads are still bridged?

AHA! success! I got megatune to recoginize it when the ini is set at MS1. But I cannot get Msnse to write to MS, what exactly do I need to bridge> The 2 holes in the little box that says boot?

i was getting that message but resolved it.... did u jump the gun and set ur megatune to msns_extra before you downloaded the firmware? .... if u havent downloaded the firmware yet test it under normal MS1 .... just go to the configurator in megatune and set it to MS1
