Hey guys,
question on the AP's boost reading. I am usually at ~20 inches of mercury (vacuum) when idle and I have peaked around 20psi with my old Stage 2 tune.
With the AP, when idle it's reading in boost at about 5psi. I was on the highway last night on my way home and it read 50 inches of mercury the whole way in cruise control. I have peaked with the COBB Stage 2 AP at 30+ psi.
What's going on here? Is it reading in a different measurement?
Thanks.

I think they read in absolute so you have to subtract the atmospheric pressure. Its not that great of a boost gauge(anything reading the OBD2 isnt totally awesome. I would buy a mechanical gauge(Best read possible in my opinion) and maybe just show other AP gauges and not boost such as A/F ratio etc.

The AP takes raw data from the ECU. I.E it is not corrected for standard pressure. So take the number (X) and subtract 14.7 to get the correct value.
X-14.7= Correct Boost Reading
Numbers are still kinda funky, but at least they are closer to what they should be.
Marshall,
as of currently, your tune for stage 1 still lags the competitors in terms of performance gains.
your claims are currently +13.2% hp and +24.7% tq for your stage 1+SF map. however, APR's v2 stage 1 /w intake is +24.6% hp and +51.9% tq.
do you have plans to close this gap with OTS maps?

Ready to race!
What parameter are you using as there are several boost related? My gauge reads boost fine

I'm having issues. I believe it's their placement of the MAF on their intake that is throwing off my ratios. My long-term fuel trims are near 25%, whereas it should be around 10%.
Getting two codes: P2177 and P0420. Cleaned the MAF disconnected and reconnected the battery, same issue.

Would love to hear from someone with a carbonio intake and cobb tune

Hey there! What map file did you flash to the ECU? Do you also have a downpipe installed on the car? If so, make sure you've go the Stage 2 OTS map flashed. You can browse to Tune, Show Current Map to verify the current map flashed to the ECU.

It has been sorted. Thanks. I had the Stage 2 file with my turbo back, but I used my old breather filter setup and used the plug on the intake. I put your hose on and it's all good now.
Thanks! Loving the hardware/software so far. Incredibly smooth and drive-able.
