Hello guys!!
I have n14 ep6cdtx engine with maf sensor (they don't have all engines maf)
Anyway:
I tuning my car and i have problem with the map sensor it maxxest at 1,5bar and i want to run at 1,8bar!!
Are anyone who know with which map sensor can replacement?
I see bmw f30 map sensor the conector plug is the same but i don't know if my ecu can identify !!

 

My MAF and both MAP sensors are all OEM --- 2007 MCS N14 built for USA. I'm tuned for 30PSI --- about 2.1 bar. Are you sure your turbo can produce 1.8 bar?

 

what! tune are you runing>!

 

Upgrade piston con rods intercooler turbo gt2871

 

You probably need a Manual Boost Controller. My Garrett was factory set for about 12 PSI. They recommended a slight increase in linkage adjustment to 15 PSI, then use an MBC for whatever I choose to tune for. I'm guessing your GT2871 is bigger, so you might not need to adjust linkage, just connect an MBC. Remember, Garrett waste gate works on pressure, not vacuum.

I'd like to see how your GT looks while mounted --- gotta be crowded in there. Post a pic?

 

I take pressure from the turbo and i change the wastegate ! I put boost control but i can lower the boost if i tern the boost to low the car run 0.8 bar if i close the boost control run max i don't know why they do that!!

 

I make custom ecu program

 

Just curious Where is your maf sensor? How did you route that intake? Where did you put the filter?

My tuner told me to remove the maf because it limits boost apparently. Without a stand alone he recommended a speed density pressure tune using stock map sensor @ 25 psi using a 47mm ko4. My turbo has a vacuum driven waste gate tho.

They said they were having problems with the maf in high boost applications for some reason

You said you have an n14? That looks like an n18 to me......

 

Nice pic! These Garrett's take a lot of extra space for all the plumbing. I don't recognize the layout --- what is the year / model of this car?

Manual BC's are continuously variable, from turbo factory default WG setting (0.8 bar?) to whatever the turbo is capable of producing. The adjustment turns about 10 full turns. I'm not sure how the automatic BC's work. If the GT2871 is capable of 1.8 bar, you might have a post-turbo leak, your boost controller isn't working (or can't handle the GT2871), or your custom tune needs work. 1.5 bar is the max boost the OEM ECU can handle. Your custom tune needs to change this max setting --- beyond my capabilities. Manic can tune the n14 to at least 2.0 bar without using fuel / boost cut defenders.

 

I'm running OEM MAF and MAP's, and my GTX2860R produces well over 30PSI --- currently set to 30. Removing the MAF is probably your tuners preference for his recommended tune. Can you explain the "speed density pressure tune", and how it differs from others?

 

Well, here's a few links that can explain how these types of tunes run way better than I. I am not a tuner but paraphrasing what I was told, he said the length of plumbing and maf sensor with the stock intake setup would not allow turbo to reach peak efficiency/spool slower.

He said they were also having problems with boost spikes using the maf with higher level tunes/big turbos. His tune takes pressure readings off the map sensor manifold pressure and correlates to rpm using stock ecu. This eliminates all the intake piping, deleted the MAF, and allowed me to run a filter basically right off the turbo similar to the DNA intake setup. I had to move my coolant res to the firewall where the oem filter was.

Couldn't find any mini stuff but here's a few links that better explain pressure tunes. Let me know if u have more questions. I imagine it's possible to go that high using maf but your right the map tunes are just his personal preference.

I was told that if I want to safely go over 25 psi without disabling knock sensors and emergency fuel cut I would need a stand alone system.

Oldbrokenwind, which tuner did you go with? Manic? I ending up going with jmtc

 

The maf is behind on the air filter

 

Nice. What's your reasoning for plumbing it low? Does it stay much cooler down there? Better air flow even with the longer piping?


I ran the intake just sticking straight out from the turbo the air filter sits where the res used to be. I'm curious how it compares in temps.

Is that exhaust downpipe custom?

 

Great article, thanx for the link.

I'm guessing that JMTC's explanations are all referencing tunes with ECU controlled turbos. Most Garrett installations are manually controlled, and as a result, no "safety" features. But, what's "safe" about all that post-turbo plumbing with >25 psi, regardless of controls? Is JMTC doing their own tune, or installing a "big-name" tune?

My Manic tune installer was EuroTech in Tempe, AZ. There's one or two closer but I met him last year at AMVIV --- very likable, plus, I have family in the Phoenix area.

 

Jmtc is in Arizona as well, San tan valley just outside Phoenix, go give him a shout next time your in town. Very nice, knowledgable, technical dude.

His tunes are all running off standard ecu although he does work with stand alone systems as well, I didn't get that far into it with him. I told him I wanted to go as high boost as possible while still being "safe" even though it's an oxymoron.

Your right nothing's safe about big boost but I wanted to keep knock sensors and emergency fuel cut intact just in case I detonate as these cars are known to do. Especially with timing so far advanced. He has a write up in a link below.

I believe he creates his own tunes/ has his own tuner in house. It's not "big name" like manic, but after speaking with him I decided to give them a shot. Try getting nick with manic on the phone lol, not happening. I think the Garret's are required to be manually controlled given the pressure driven waste gate.

Here's what they have to say basically:

Peugeot Rcz 2010 200thp factory with ep6cdtx engine

 

Yes all pipes are custome and exhaust

 

Who is your tuner?

 

Yea , looks like an similair N18 Engine MINI side or the Peugoet RCZ 200THP, which is shared

 

They told me are the same with r56 but my engine have variaball the mini no!

 

The MINI R56 N18 have Variable Vale timing, the RCZ has a different turbo and intercooler system.

 

You know how to fix my problem?
