I did and they told me no. I found a few shops that could bench flash my ecu, one tried for 9 hours and couldn't get the ecu to allow him to see the stock map! I gave up and went back to JB4. It works well enough for me and makes plenty of power. As soon as I get the money saved up Im looking at the Stage 1 upgrade turbo.

How much time should it take to install pure stage 1 on n55 135i??
Was quoted $1200 - $1500 to do it in approx 10 hours here in Australia.
Seems excessive??

[Orange fever]

YouR. Right on the 10 hours...
Talked to my local shop...

Yes, my stage1 was done in under 4 hours. That is if you just get a core. If you get a full manifold (normally you dont with stage1) like with stage2 it takes 8/10 hours.

[GR1P]

stage 1 is 4-5 hours

stage 2 is 6-8 hours

Stage 1 is only a CHRA swap

Was wondering if anyone could help.....my brother has a 2011 135i dct, just got pure stage2 upgraded turbo. We have been runnin the car on cobb ots... the fbo map aggressive, the car will not stop misfiring. We did new ngk with the correct gap, we even got upgraded coil pak from my mechanic, has anyone had this issue? And if so wat have u done to correct, thanks.

Dude there is no way your OTS map would handle stage 2, completely different flow, AFR, and boost across the rev range, you need to have it tuned ASAP. IMHO

Good luck, your brother will love it once you tune that shiiii

That Cobb is not going to help lol. Need atleast jb4 with e85 wiring and a stage 2 fuel pump to get the benefits including a cobb Back end flash.

We actually backed off the tune a bit from aggressive to sport, and dammm the car pulls like a fighter jet about to take off. .lol getting tuned this sSaturday, we'll see wat happens.

Do you need fuel pump upgrade for that setup on stage 2?

Nope. Stock fuel system is ok. If you need pure st2 let me know

[c_ozanich]

just got the stage 1 installed and put back together; throwing a 2C57 generic code, valves are ticking much louder than normal and not building boost/throttle holds steady at roughly 30% in terms of "feel" - I'll go all the way to floor with it but there no change in response after about that 30% mark.

Am i looking for a vacuum leak somewhere? I thought I got everything re-connected; oil pressure is good and no coolant issues according to car.

Anyone know if it's possible to run pure stage 2s on N55 on jb4 map 5 or does it require the 3.5bar TMAP and flex fuel wire?

To have the benefits of it yes if not dont upgrade. You are better off with stage 1

Stage 1s are out of the question as I already have the stage 2s, it's just to get them installed. I was under the impression that the stage 2s produce more power at the same psi than would the stock turbo.

I do plan on adding meth to the equation but not in the near future, thus, I'd like to know if I'm good to run my stage 2s with my current jb4 maps—or better yet, a custom map 6 targeting 20psi which is in the readable range of my current TMAP sensor. I'm not sure if this is even possible with just my jb4 and stage 2s (no flex wire, no 3.5 TMAP, no backend flash) or if I would be limited by octane (94oct).

Unless I'm thinking of doing something like the guy you were correcting here.

Any updates? I assume you got a custom stand-alone flash?

When you say "only on stage 2 turbo" is that without a BEF, flex fuel wire, and 3.5bar TMAP? I was hoping to just set jb4 with map 5 with 94 octane after installing my stage 2s.
