yeah, I have an upgraded clutch. First I tried upgrading to 550i clutch and stock DMFW, was fine for stage 2 E30, but would still slip on stage 2+ E30 when going WOT in 5th or 6th gear. Right now, I am running Spec 3+ with oem DMFW, and it is holding up, can WOT 5th and 6th gear all day, no clutch slip.

good to know, guess I will stick to stage 2H 93 and stage 2+ e30 once I get PS2 installed. no more custom tuning for me, lol

i think your 550i clutch issue was a fluke, or your original dmfw was glazed.

when you installed the spec 3+ clutch, didnt you also install a new dmfw? that's a big changed variable.

550i has been proven alot, and just recently, proven to hold 600 ftlb.

yeah, I got brand new luk DMFW this time, the original flywheel still looks fine though, so not sure what happened. my guess is - the shop that installed the 550i clutch didn't install it correctly... I used a specialty BMW shop for the spec clutch install. Ultimately, I like the spec 3+ way better, it has a more firm, sporty feel compared the 550i clutch, and it is very grabby, just as I like it, lol.

A PS2 definitely unlocks the Stage 2+ map’s potential: https://f87.bimmerpost.com/forums/sh...55&postcount=1

The boost levels between the turbos are the same on this map, but the stock and Stage 1 turbos just can’t flow enough to keep power going above 6k. My Dinan turbo hits the same torque peak number as the PS2, but 1100rpm earlier—it dies above 6k, tho.

I’m just not keen on any additional turbo lag down low, so we’ll see how my “Stage 1.5” TTE460 turbo dyno’s with the 2+ map. Hoping for no lag and a flat top end.

why not just go PS2?

Thought I (and others) made that clear. Lag.

An M2 buddy of mine with a tuned PS2 making more power enjoyed driving my car more around town.

you'll hate low rpm with a manual but you can much more easily adjust rpm on the fly.. launching the car is gonna be so not fun but top end on that map with that car is gonna be a blast. it will help that your car is lighter though.

Most people don't understand, massive torque down low is a big no-no, you'll have wheels pin and you'll definitely break parts, guaranteed (driveshaft, transmission, axles) which is why that tiny bit of lag from the PS2 will save your car in the long term. There's a reason why my N55 with PS2 currently has 169k miles (90k miles on the turbo) and I do a bunch of launch controls (hundreds, for data logs) and hard lapping.

do you have any 1/4mile runs?

look at the whole thing.. its like at first it's pull power then nothing. that mph is so so low and you can see it in the acceleration graph line.. wtf is going on in that run.. like they went to 50% throttle or something.

This is pure pump 91 on PWG, you can ask the PTF team when we were developing the OTS maps for PWG, me breaking into the 11s is a world record for pump 91 on the N55

Its just octane, if you ran 91 oct on a 91 ots map, most cars would go nowhere near the 11s



Here's another on the same map, pump 91.

yeah, I guess.. just weird to see I guess. I need to go back to a 93 octane map and do dragy ones to see the mph again I guess

most people don't know how much octane affects numbers on this platform, it's pretty considerable.

Going from 91 oct to 93 oct to E30 to 100 oct is huge.

I recently just moved to the east coast and the fuel here is considerably worst than where I was before, the 91 octane is not the same where we had to make a custom ACN map to run it, we had to reduce boost from 15.7 to 14.5 and play alot of the timing and AFR so it didn't run too rich and crash the fuel pump.

You’re right. I didnt see the octane until now.

Yeah I got about 6 cans of the 32oz professional ones, 4-6oz to the gas where I currently reside makes it barely 93 Oct, I try not to use it all the time as it does turn plugs orange. Probably once every 3-4th fill up.
