The timing is advanced for max power on pump 93, even at cruise. That would certainly lower EGTs a bit....

+1 what FoundSoul said. AFRs are similar as the MS is shooting for 14.7:1 just like the stocker. The car is definately poppier with the extra timing and without the AFM choking the intake.
That's post 2200!

MS Day 3
Reworked the hot side charge pipes a bit to fit an airfilter straight off the turbo easily. Pulled out that friggin coolant hard line that popped out on me the other day and trimmed its bracket down so that it fits with the greddy mani. Had to remove width and height from the bracket and elongate the hole. PITA, but it's done and secured. Won't pop loose again.
I played with megalogviewer. AWESOME PROGRAM! Screw DLL. Made a few tweaks here n there. Car runs well, though cruise is still rich. Can't wait until tomorrow when it gets tuned up!

Diag. box is only good for a few things, what would you still need it for? You can still jump the fuel pump, that's about all you might need.

You dont need to jump anything to set the timing/idle...infact you don't even need to rotate the CAS. Just tell MS to be a fixed 10deg...then change the crank angle value untill you see 10°.
You should still be able to ground the fans and fuel pump circuits.

The only time you'd need to move the CAS is if the trigger angle needed to set base timing properly falls between 20 and 50 degrees.... you can't use a 20-50 degree trigger angle as it will limit your maximum advance. So IF you fall in this range, set your trigger angle outside of this range and adjust base timing using the CAS, or at least get it close and then fine tune with MegaTune.
Generally with the MSPNP units most cars are falling in the 53-63 trigger angle range.

not necessary, but unless you hook it up when you do get knock all that you'll see in the log is how many degrees retard MS as done, you won't actually be able to see the spikes.
The spikes are superimposed onto the CLT line. An added benifit is the spikes are negative so your coolant suddenly becomes much colder, so MS injects more fuel for a brief moment. It's a beneficial side effect IMO

Not yet-- but I want one now .
That meant I was leaving to go help Ben dial his car in. I'm sitting in the passenger seat, on the dyno, right now. We've tuned to 11psi, 214.5 wtq and 218whp so far. We're about to try and turn up the boost a bit...

Actually... we started using that a while ago, right after I posted the MBC numbers. Oh... did I fail to mention that the MSPNP comes complete with electronic boost control built in ready to rock? Guess I wanted a live test first
It's a bit different using it without a TPS, reduces your table to 1x8 essentially, but it still works great actually. It's simple, but very effective. We just dialed it in in open loop.
I'll let Ben share his final numbers... I can't spill all his joy .
We're about to go for a test drive!
