dont tell me to put the n75 back on.. its not an option.. it was running fine without it on my old tune but since i loaded my own first file i need to get the codes for the n75 to go away.  what things need to be changed to get rid of the code with the n75 unplugged.

Put the n75 back on, throw away the EBC.

LOL dude, read more, learn more.  The n75 is an ebc.

The info to remove codes is also here.  What you are trying to do is totally bass ackwards.

Yes, but perhaps he wants to be able to switch boost profiles on the fly using his aftermarket EBC.

Yes I like my eboost2. I searched about deleting n75 but couldn't find a straight answer

We can do map switching now too.

It just seems silly to swap a ebc that works with and in support of the factory ecu for a standalone unit that really has no more capability.

Yes it is... One that has a PID loop that doesn't work over 2550mbar absolute.  How many of you guys tune past the MAP and drive your cars places with excessive density altitude changes on 91 octane?

The great thing about my MBC is that I never have overboost issues with air density changes... That means my tune is consistent whether it's in the 20's here or 120+ here.  We see 100 degree temp swings in Arizona.  I pin the throttle at 80 in 6th gear and I see the same boost regardless of the outside temp, or if I'm in California, etc.

If you leave the N249 working, throttling losses are not a problem because the bypass valves are open until the ECU requests boost.

Leave the N75 in place and cap it off.

To disable throttle cut for overboost, locate KFDLULS and FF the whole table.

That is of course unless somebody can prove you can use the N75 beyond the map limit and consistently control boost regardless of air density or engine load.

Don't search n75 specific but rather how to remove fault codes in general.  It was tony or setzi I believe that made the post on the process.  Of you really want to do this leaving it plugged in is your easiest route.

Think about what you are saying... Above the map limit we are working off a fixed dc, which is then a fixed value much like an mbc.  In my area we have roads with multi thousand foot elevation changes and our seasonal temp swings are over 100 degrees.  I am very well versed in the behavior you seem to like about your mbc, the n75 will do the same.

thanks guys ill figure it out....


for the n75 lovers.. i dont have it anymore.. the car is a full custom 3L with no factory rails/vac/boost sources.  the eboost 2 is already there.. and i enjoy it.. hence why i said its not an option to go back right now.  i see no problems running the EBC.. nor do i see any major pros to the n75.... it is what it is at this point.

A ball and spring MBC is a mechanical PID whereas a fixed duty cycle on the N75 is rate limiting your wastegate bleed through what can only be described as a choking through a flow limiting orifice.  

Because the flow rate through the orifice at a given upstream pressure can vary based on the downstream pressure (ambient), there will always be a proportional gain or loss based on changes to ambient pressure.

A flow limiter is not a pressure regulator.

zero out kfldimx and kfldrl  i ran a mbc this way with the n75 disconnected.

Where is that thread how to disable cels, ive been searching and cant seem to find it.

Ever heard of KFLDIOPU? Not disagreeing with what you said, but you describing your symptoms sounds like that map was just not dialed in right/left stock.

Off topic

Excuse me prj, I sent  you mail and pm: can / would  you help m? Kplease !
Thanks and Excuse me tor this off topic

No, I can't help. And I will never respond to PM's where people just beg for random stuff.

Ok, no problem, but  I don't beg and I'm trying to learn!
Thank you for your NOT help

What are you doing calling people out in threads to respond to PM's?  Go back to audizine please and thank you.

So post your question here. Answering PMs are pointless because it means you can't refer to them later if somebody asked a question that was already answered.

Same, I am so tired of people pming me demanding tunes and checksums and such.  Make a thread if you have questions and learn like everyone else.

I also love PM's that are like: "HAY DO U HAS WINOLS 2.0?"

And what is with new members dishing out negative rep, I have seen a lot of regulars getting it lately, I think there should be a 100 post minimum before you can be a hater.

Most of them are looking for free tunes and not for information on how to tune themselves.  Unfortunately that mentality is right in line with retaliatory actions like dishing out negative reps.
