my guess is the timing...I was always seeing 14.7-15:1 cruise on the stock ecu.
|
The timing is advanced for max power on pump 93, even at cruise. That would certainly lower EGTs a bit....

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! |
Leaving for the dyno now. :x:
|
Can't wait to hear the results.
Stupid question about MS: will using it standalone make the diagnostic box useless, or is it still functional? Would seem that it should still be functional, but who knows whether the ECU had its little hand in the operations... |
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.
Ben: "break a rod" (i guess that's what they'd say....) |
I was thinking for setting the timing and mechanical idle, as well as jumping the fans. I'm only really concerned about the timing and idle.
|
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. |

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. |
BTW-- I'm leaving for the dyno now too...

So does that mean your car has a Turbo on it now? |

Yes. The CLT wire isn't necessary.
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 |

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... |
Nicely done guys! I bet he's really "squirting" now!
|
ahhhh...i need more dyno, great tease.
|
Must get my squirt finished so I can start tuning...
|
241 whp 230 wtq so far, working on boost control issue, running to only 6500 rpm. boost is falling, and hp is still gaining hard @ 6500 where we end the run. dynapack dyno, 90 deg ambient
|
sounds like it's MS EBC time.

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! :skid: |
