Overall, mine needs a bit more tuning, but everything works as DIYAutotune advertised, and mine is a "non-standard" unit with the 4 bar map and baro correction. The car starts, runs, and drives. The AC and cooling fans work. The idle valve settings are pretty close to perfect. My cold start enrichments are not perfect, but honestly I've not been working on them like I should. It is rich in cruise, and has some really rich spots in light load, but that's just tune related and it needs a little bit of street tuning on the fuel map. It's been more fun and less troublesome than I was expecting. Installation was easier than any engine management solution I've used. Support has been great. Jerry (FoundSoul) @ DIY has been friendly, accomodating, and very helpful.
I wish there was a little more hardware in the box, specifically support for water injection. I am leary about having to bust open the case and install my own bread board to run WI, as well as mod the board to run a variable TPS. Not because I doubt my skills, but because it (understandably) voids my warranty. Those are probably things I will wait another 11 months to do. Maybe they could be incorporated as additional cost options in later builds?
The open loop boost control works great. It was a nice bonus to the package. BUT since I'm greedy and ungreatful I'm looking into closed loop boost control, especially because the software can pull boost with MAT and knock events.
Neither of those are advertised MSPNP features. However, both are MegaTune software features that would work if supporting hardware were available. The information to modify the board to run vari tps is in the manual.
My MSPNP does everything that it was advertised to do. The car drives around as it should and makes good power. Installation is simple. It is a good engine management solution, especially for its price tag.
FWIW, I believe I have $970 in the hardware (I picked up the unit and had to pay sales tax !BOOO!).
There are 2 local guys with in progress 1.6 turbo builds (atlanta93le and emerilnut) who have both already purchased their MSPNP units. I'm looking forward to seeing their results.
The $970 figure includes the KnockSenseMS and GM Boost Solenoid from 3rd party vendors
