Dyno'd the MSP, need advice on the AFR

[kmfdMZ3]

3" custom thermal jpipe back, ~7.5psi, unichip OTB tune Map A, turbohoses smic with hardpipes, injen CAI. my god that tune is scary. closed loop afr's till 4k, even with the unichip. i'm assuming if the car was reflashed that i would need to retard the timing from 2-4k.

I have not tuned my MSP yet, but I agree you are running way too lean until 4k. In closed loop, I would expect to see fuel in the 12-10 range like you see over 4k.

if the ecu has been reflashed, can the unichip (or any other piggyback for that matter) still be used? my friend with an 03.5 told me his ecu keeps relearning and keeps the stock fuel map instead of his ems' map.

Too lean down low, too rich up top. You just can't win.

 

[kmfdMZ3]

true, but i'd rather have it running rich than maxing out at 15 in WOT

interesting...here is my unichip dyno. At least your graph looks decent, not totally f'd up like mine.

I have a re-flashed ECU too with the unichip. Stock tune on Uni.
this was my run @ stock boost with just the CAI
and hard pipes. they only ran it to 5000 rpm's for some reason??

Wow that ones even scarier. Well at least we know why the MSP blows up so easily.

I just dynoed my MSP today and the numbers are 175.41 hp and 194.84 tq. My air/fuel mixture is far worse than your guys. It looks like the numbers are too low for the graph and then comes back up between 5500 and 6000 rpm. What can I do??

 

[CHIQLES]

so do they go full throttle right off the back?
