I'm upgrading my MS1 v3 board to MS-II. I did the board mods per
's little color-coded how-to:
IAC1A to JS10
470Ω between 5V and JS10
TACHSELECT to XG1
TSEL to OPTOUT
5V to top of C30
swapped IGN and IAC2B
Removed D1 and D2 jumpers on top of board
Replaced R12 with 470Ω
As you can see from the attached pic, I have my spark outputs the same as the original MS1 setup (just swapped). I have not done JP's spark mod.
I got the firmware flashed just fine, using MS2 Extra 3.0.3r. I'm working off of the DIYPNP base map and changing it where needed. I noticed that map has spark inverted. Mostly I just want to verify that I should still be running normal (going low) with how my outputs are configured, and that there is not some difference just between MS1 and MS-II. Confirm?
These are DIY's values for the stock CLT sensor:
-4 / 16150
104 / 1150
176 / 330
and the default settings in tunerstudio for the GM IAT:
-40 / 100700
86 / 2238
210 / 177
But for my parallel setup (without R7 installed) I should substitute 1450 for the CLT and IAT bias values, same as I was using for MS1, correct?
I scaled reqfuel for my 550s but it looks like the DIYPNP base map will have me running pig rich if the fueling calcs are at all similar between MS1 and MS2. Like my idle VE cells were in the 20s and the base map is in the 40s. Thankfully VEanalyzer live should make quick work of it. I still need to fiddle with the tables a bit but hope to have it running tonight or tomorrow.
