A. What is the differance between Brianeacks pnp vs Ms pnp?
not much, but a enough to make a bit of difference. DIY autontune are who i actually buy all the components from, they put together a nice package deal to make building MSs easy. They took it one step f
urther and made a PNP package w/ support and warranty. They built a few custom circuits to allow the a/c to work with it. You can still use the a/c with a built MS, you just have to keep the stock ecu. not a big deal. I use the v3.0 board, the PNP is based off the 3.57 board, both use the same software and hardware. It really comes down to how much $$$ you want to invest and if you need their support and warrenty and whatnot.
B. And what are the pro's and cons of EMU vs MS vs Braineacks pnp
there's a reason a I went with the MS. If the MSPNP was available when I started looking for a better solution I might have gone with their unit, however I like DIY stuff.
C. Will one make more power or better efficency, if so how much.
yes, the ability to tune both spark and fuel maps is very benefitical.
D. greddy seems to start out cheaper and always nickle and dime you to death. This kit has software universal wiring harness. Is that all I need.
the EMU will ultimately cost more than my setup.
E. Would it be better to buy a e manage an just use the auto tune?
MS has autotune features too
F. I seen MS has a knocksence feature. and boost control, Does EMU have that?
i dont believe so
You sound like a candiate for the MSPNP, you wont have to do a damn thing but replace the ECU with the new unit and enjoy. other than tuning and running a vacuum line, that's really all that's involved. MY unit will give a you a few extra steps (which are just as easy) if you're willing do it to save the $$$.
