Challenge Sport Xpipe (HFC) + ESS Tune in for Emission Test

[m3whip]

     Featured on BIMMERPOST.com

I would really appreciate it if you guys could help me

So i am at 55miles with Stock Xpipe, no CEL and no Tune. All reads ready except for AIR - Secondary air system monitor and EVA - Evap system monitor.

CODES
P0001 - Fuel volume regulator control Circuit/Open
U0001 - High speed CAN communication BUS
B0001 - Driver frontal stage 1 Deployment control (subfault)
C0001 - TCS Control channel "A" Valve 1 (Subfault)

Would i pass if i go in?

Search ftp drive cycle on the forum for details. But this is what you need to do

I'm assuming you had the challenge xpipe plus tube but now you put the stock xpipe back on and flashed back to stock tune.

I'm in the middle of the same thing. Just swapped my xpipe for one with oe cats and switched ESS tune to stock.

I was able to get the 20 to 30 mph and 40 to 60 cycles to turn it's corresponding monitors on by just gently driving around not letting rpm get past 3k. And that's with stopping for stop signs and stoplights... but when I ran my scanner those monitors where ready.

I got secondary air to go to ready by letting it idle cold (engine doesn't just need to be cold... needs to actually sit overnight for 8 hours) then let it idle for a few minutes cold and it set the monitor on.

I still have evap to turn on... maybe a couple more cold AM starts will do it. But I'm not too worried because I think California let's the evap be the only monitor not working. (Can anyone in socal verify?)

You need to see how many monitors your state requires. Some allow 2 to be off some allow zero. I think since 2015 California allows evap to be off.

Thanks for the input. I appreciate it.
I got the AIR to go ready now. I still have the EVA not ready though. I'll have to check if illinois requires EVA

As you can see from the drive cycle instructions, EVA is set by letting the car idle after a long drive before you shutdown. It says to leave in gear.

In gear, yes i did that. I guess i'll have to do it often.

Thanks

So that means stepping on the brake like at a light for DCT owners and with the clutch in for manual owners?

I read a different set of instructions that had NOT said leave in gear, so I didn't. passed emissions after doing this cycle twice, 50 miles on the clock.

Yesterday, i drove 60mph for 20+ miles and came to a stop idle in gear for 5+ mins. I still have the EVA not ready

What did you have to do to clear the last code?

I cruised on the highway at light throttle (not past 3k rpm) at a speed of 50-65mph for 15 minutes. I made sure the gas cap was tight and the fuel tank was 1/4 to 3/4 full.

drive it cold for 15mininutes keep rpms below 3000rpm , drive 40-60 mph keep rpms low , worked for me . after resetting battery.
