Default Let Lance try to catch me now! New MAF, new FATS: 6.94 (data included)

No longer the slowest S4 on the planet! VAG codes did not come back! Thanks guys.

So does this look about right for stage 1?

TIME RPM MAF

51.61 4280 216.17
51.92 4400 218.08
52.23 4560 219.17
52.55 4680 226.5
52.88 4840 228.19
53.21 4960 230.86
53.55 5120 228.08
53.89 5240 233.75
54.23 5360 235.11
54.58 5480 234.61
54.94 5600 237.47
55.29 5720 237.94
55.65 5800 237.81
56.01 5920 239.92
56.38 6040 241.83
56.75 6120 240.53
57.12 6200 242
57.49 6280 242.53
57.87 6360 244.53
58.25 6480 243.83
58.63 6560 146.36

Anyone want to show me how to graph this data?

Weight 3750, 60 degrees F, 92 oct, MTM A-box chip, RS4 IC's, tire radius 12.7 (235-40-18)

With Stage 1 and IC's, unless you're at super high elevation, that's very slow.

Default MAF values are on the low side for a chipped S4. What altitude are you at?

Clearly much better than before, though!

Log boost and timing. Your taller tires skew it a little higher, but should still be sub-6 sec

Default Previous VAG here; had been seeing some 'cat efficiency' codes

Haven't come on again since yesterday. Sometimes I get Bank 2 cat also.

17536 - Fuel Trim: Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
16805 - Warm Up Catalyst: Bank 1: Efficiency Below Threshold
P0421 - 35-00 - -
17538 - Fuel Trim: Bank 2 (Mult): System too Lean
P1130 - 35-00 - -
