Cold side is much, much better. The charge air comes out of the turbo in fine pulses which can read inconsistently on a MAF sensor. The intercooler smooths the airflow significantly, sort of like a MAF screen. MAFs do not like 300+ degree air flowing over them, either. You will get a more accurate reading with charge temps closer to ambient.

 

But more connections yields more potential for fail. The wiring is long enough, just had to route it back out of the OEM loom a bit.

 

Yeah I was just letting you know

it's plug and play like the AEM extension is

 

Thanks, I didn't know one was available separately from anywhere.

 

Just ordered my lower and upper CP yesterday, comes Tuesday cant wait

 

Ryan offered me the harness extension today. I don't need it but you gotta love that kind of support!

 

Took ~2 hrs to install, I put all the sensors in the CP before installing from underneath but I had to get the pipe in place without any couplers on it then slip the coupler as far on the IC as I could, get the pipe on the TB with the coupler, get it on the IC and slide the coupler back. Perfect fit! Thanks ZZP!

Time to get tuning!

 

You're welcome. I hope you enjoy it.

 

we should get a group buy going on this beautiful new prodect ZZP! <3 I know ill be in if you do

 

Any updates on this? How's the tuning going? What all have you had to alter thus far in your tune?

 

Logged a 50 mile drive this morning.

Initial 10 mile run Sat had the LTFT's -7.8, Multiplied the whole table by .93, drove it this morning and LTFT's stayed between -0.8 and + 1.6 in traffic and freeway mix.

Seeing +7 ~ +10 in the 800 rpm 10 & 20% load areas so I made some changes to the MAF correction table for the drive home. That's an area that has a lot of compensation the wrong way stock.

Very good mod IMO, and easy to tune.

Driving response is much improved since the MAF is ~10' closer to the intake/combustion/feedback process. Rich spike at tip in is gone.

 

What all did you have to alter as far as the MAF correction goes? Is the piping a different size and you just have to figure out what the difference is and multiply by that percent difference to get the initial retune working? (Then of course log and alter from there)

 

The few cells I modified in the MAF correction table with the paste special multiply % function in HP Tuners after copying the log data I wanted to correct. I think it was about 10 cells in the upper left area, low RPM & load.

The MAF frequncy table was shifted with a multiply by .93 after the initial log. (~7.5%) In contrast the K&N drop in filter will skew the tables that much.

Easiest tuning based from the stock tables I have seen to date.

 

Great info! I may be doing this mod next since it doesn't appear there is too much retuning outside of the norm for mods! Have you noticed any significant increases in flow?

 

Not really, but with my mods the stock turbo is pretty maxed out already. The stock cold pipe isn't that restrictive, but the rubber ends were showing excessive bulging wear after 36k miles, 27k tuned to higher boost. The rubber ends were pretty well weathered after two midwest winters and up to 27 psi boost at times.

 

Update...

Wached the trims for around 10 days now, initial 7% MAF freq correction was damn close. (X.93 on the entire table)

Lots of positive MAF correction in a few cells at idle, but ended up taking out correction in a lot of the cells at low & high rpm & loads. (Closer to 1.0)

Very good results on repeatability compared to the MAF sensor in the Hahn intake. LTFT's staying between -0.8 & +1.6 in all weather and temps so far.

ZZP MAF relocate FTW!

 

Thanks for the update. It sounds like your settings are very close to how I have mine modified.

 

pics or gtfo

 

i actually did a MAF relocation also but am having problems since i did it. For some reason while i am just driving normal, my A/F will go CRAZY rich (10.0:1) for about 30 seconds then throw a P0140 code. I dunno whats going on. Vince is trying to figure it out but it's some crazy **** going on

 

I lost the pm you had sent, but I seem to remember around the same shift in the midrange. I just worked off the stock tables. It was a lot easier than tuning the AEM or Hahn intakes were.


Tried to take some when I did the mod. Too much stuff in the way from above to see anything. I'll GTFO now.



If the CP is up tight against the throttle body, you may be inducing vibration into the MAF sensor. Just a thought as I don't know if you have the same pipe. I left about 1/4" between the CP and TB inside the coupler.
