This kinda makes me wish I had gone with a MS P-n-P ..... not! Tooo complicated for my ability and patience. http://forum.miata.net/vb/showthread.php?p=3236711#post3236711

But the MS is WAAAY BETTER while the PC-Pro is "just a piggy-back". :biggrin:

With the need for a dedicated in-car laptop, bags of capacitors for ignition control if you want it to control ignition and now this thread, I would say it is PNPNPNPNPNP and play, and play, and play, and........

It's safe to say that I would have felt extremely nervous trying to depend on the Megasquirt going through those long stretches of desert on my trip from New Orleans to California and back. There is something to be said about the K.I.S.S. approach of the PC Pro. Even if the PC Pro somehow totally grenaded itself, I still wouldn't be stuck out there in the desert... as I have the stock ECU and stock injectors all intact. The car would run fine, all I would have to do is tie off the bypass valve with a ziptie (and I always keep zipties and few simple tools in the glovebox anyway). A wrong size capacitor on the Megasquirt say causes the board to fry and I am 500 miles from civilization on a trip with 550cc injectors and no hope for the stock ECU to control them. Now what? :biggrin:

One thing I can say for all the flack we have gotten for using "inferior" piggybacks, is that they have all been reliable (even the ELF). In the worse case scenario you are still never stuck somewhere with exactly ZERO rwhp. Just maybe back to 90rwhp :).

Now, I did have some lean issues at 0-2psi when my car climbed the mountains in western Colorado and I mentioned this to Jeremy at FM when I visited FM (great people btw!). However, after the visit I decided to try some minor adjustments to the PC Pro and was able to fix the issue. Turned out that all I had to do was adjust the low boost fuel. A few touches of the buttons while driving and it was done and driving great again.
