I have the following mods on my 2000 M6 Z/28
ported t/body,SLP lid,polished,descreened stock MAF,LS6 intake,B1 cam w/221/558/114,918 springs,kooks headers w/ORY,magnaflow CB,ram stage 4 clutch,steel flywheel,4.10's in a moser 12 bolt and M/T DR's on convopros.

I had a speed mailorder tune done after the cam and it worked well to elim the rear o2's,EGR,AIR,CAGS and correct speedo but the O2's ran .980 at WOT w/no knock and 25* timing,LFT's were -4 to -6 all the time.I installed the vinci tune w/#3 cam and WOW what a difference this car is in driveability at ALL ranges,freakin awesome.I now have -2 LFT's and .930 WOT readings with 25* timing,no knock and the LFT's stay at 0.I added 10% timing and it stays locked at 28*,no knock.

I'm very impressed with this programmer,I can't believe the results and the car drives and feels so much better and what gets me is in normal driving its crisp from takeoff on up.I'm going to have a wideband dyno session this weekend and hope to find that my falloff at 5300 rpm was related to a rich condition.

 

glad to hear you like it. i ended up using CAM #3 +10% power enrichment on the wife's 99 formula with stock cam + VHP ported heads. another friend of mine used it on his 99TA M6 and picked up at least .5 on two different tracks. he goes by jwitt2 on this board.

 

Sounds like the hand held programmers have come a long ways. Push a few buttons and your done versus chasing your tail like I am just for one small change to the engine. Congrats!

 

Thanks for the update man..
I'm ordering mine friday for my c5 auto 3:15 gears.The folling month i will add long tubes and this Vinci cam.How high did you have to raise the idle?
I'm also going to try and use the 85 mm SLP MAF thats recalibrated to work with stock PCM.Anyone try?
DUR @ .004" 272*/280*
DUR @ .050" 210*/218*
LIFT .551 / .551
OVERLAP 52*
LSA 112*

 

My idle has been stock at 750-800.Nice mild lope.If I was doing a cam again I would go 224.I would try the MAF and log the changes on LFTs and WOT and see what it does.
