Have NGKs before? Stock plugs are good for pretty much anything you could run on OTS maps and stock turbos.

0 corrections across the board is a rarity. I wouldn't expect to never see any indefinitely on pump gas, but that's as clean as it can get obviously. If you're not standing on it for long periods, I'd leave it on that map and just get a FMIC ASAP. Elevated IATs don't help, but they're not that hot there.

yep, what he said. You only got 6degree (c) increase in about 5 sec now but that will change as summer shows up.

but they're not that hot there.

YET

If you shift into 4th right at 6250 from 3rd, you would likely see a little retard. But it should clean up quick. And go back to base advance (5-6degrees at say about 16+ on pump) quick.

make sure you got ngk 95770 at .021 gap max.

I told him I was running 93 as I did when I originally purchased the tune. I'm confused why a tuner would jump to blaming fuel as opposed to looking at the more logical cause of LTFTs. This is a red flag to me.

I suspected that maybe the LTFTs were to blame so I added them to the data log and carefully replicated the issue. I could tell that my LTFTs had adapted to an extremely negative value (I suspect from a previous tune). I then reset adaptations and did some light driving. The second log shows things are much happier now (to my untrained eye).

I haven't told the tuner I reset adaptations or did the exploration into LTFTs with my 5th gear test. I'm curious what he recommends I do. Maybe he is watching this thread, IDK. I'm a little upset that I was instructed to just throw on this "base" tune with 20lbs of boost w/o first considering adaptations. I supposed I am part to blame, but a base tune should be extra safe!

Testing LTFTs:

After resetting adaptations:
https://datazap.me/u/kmastl/4-16-19-...zoom=1174-1207

I dont see corrections being logged for cyls 3 and 4

Pulling a little timing here mid rpm and trims are not as tight as I would like to see ; not to mention LTFT were zeroed out.

I would think there would be some benefit in targeting a little less boost and more timing..

Better off with the stock Bosch plugs over any of the NGKs was the first part

Im with you.. on the OTS Part. I didnt get anything good on the bosch plugs once I started leaning on it with longer pulls and the NGKs were more predictable; but didnt live long. 12-15Kmiles max.

I've been using the same plugs for 4 years. Runs anything from a stock map to 25psi through 7000rpm (15Ts) with a .030" gap on pencil coils. Never misfired a day in their lives on any of it. In fact, the first set was in for 2.5-3 years untouched and decided it was probably time to replace anyway. They probably had 35-40k miles on them and still hadn't complained, but the wear on tips was noticeable when I pulled them.

I tried 95770s, 97506s and a few others at the time and went right back to the OE S55 plugs. I think Bosch equivalents came out around that time because the OE S55 plugs were dirt cheap (less than $50 a set), so I bought 3 sets, which will last much longer than I'll ever keep the car.

The NGKs are both a total waste of time by comparison. Next time you replace, lay a 95770 up next to a stock Bosch plug and take a good long look. LMK when you see it I say try the OE or Bosch S55 plugs next change, they've been outstanding. At the rate you're changing them now, don't have much to lose.

ill give it a shot, its coming up on 12K on the NGKs and you can tell when they get old.. bc it sounds sour for the first 1-2sec on cold start. Might get both and look at logs. The OEM Bosch had some bad retards as it got close to 20-30mins of drive time on a long pull - (not your average quick run - more like a drive around for a bit and then a log) - and I think the NGKs were noticeably less.

[RSL]

I meant get OE BMW ///M S55 or the Bosch S55 equivalent, not the OE N54 plugs. I had corrections on 95770s as soon as I put them in, which never existed on years old S55 plugs. I did multiple pulls daily after 45 minute commute and starting IATs of 125-135F in summer, was no different than when it was 40F. I don't pay much attention to cruise timing and haven't for years. I dialed the bulk of the corrections out long ago and is always the first thing I adjust anytime I start a new map.

[335e92tx]

interesting. ill find out what the s55 are. I think they were close to the n55s but ill check. Ebay says the current replacement is NGK.. or 2x$ for the bosch

No haha, I just had no idea when they were originally changed. I wanted NGK but they were out of stock and ehhh I don't think gapping plugs is something I like.

Yeah will plan to get intercooler for sure, will probably revert back to Stage 2 when temps get hotter, wanted a taste of what FMIC upgrade can give me lol.

By S55 plug you mean the ZMR5TPP330?

What do you have them gapped to and what sort of power levels are you at?

[RSL]

OE S55 - what I use for almost 5 years up to 25psi through 7000rpm on hybrids, Eldor coils, 93 pump, 475-500whp, all on stock gap (listed as 0.8mm/.0314", but measured closer to .030"). Pricey by comparison, but not really if you only have to change them every couple of years.
https://www.ecstuning.com/b-genuine-bmw-parts/spark-plug-set-of-6/12120039634kt1/

Bosch - new Bosch equivalents to above released last year, I've never tried. OEs were dirt cheap when the Bosch were released, so ordered them instead.
https://www.ecstuning.com/b-bosch-parts/spark-plug-set-of-6/12120039634kt2/

N55T0 (T0 = top power for a given BMW motor = M2, not Comp which is full S55) - know nothing about these plugs, but may work just as well without the full ///M tax. Looks like M2 people are running their stock plugs upwards of 40-50k miles and on PS2s without issue. P/N suggests they may be nearly identical to S55 plugs with a 0.7mm/.028" pregap instead, but no guarantee on either.

Thanks for that, will be useful when I come to replace my current 5992s.

Some new pulls 2nd/3rd gear after MHD stage 1 on cdn94 with acn94 tune. This is about 30miles after I installed xhp stage 2(got xdelete as well but reverted until xhp gets done with the break in period)
Have to say: Holy shit. if anybody is thinking about xhp on auto, its fucking well worth it. I only did a stage two, but I bought the super license. Stage 3 is where its hard on the transmission or so i've read, but wow. #Worth

I'm still new, forgive me, but we're still talking about the n54 motor here? Cause the first link there for plugs are dirt fucking cheap and I might just order a set just because

Yes, this is the N54 section. S55/N55 plugs in N54, but those specific ones. I have only used the OE ///M branded ones (first link), but the Bosch S55 plugs should be the same for $30 less (2nd link). That specific Bosch N55 plug should also be very similar to the S55 plugs for even less, but not sure anyone has tried it yet.

Use stage 3 XHP, its not harder on anything and full manual mode alone is well worth it.

Yea was gonna reflash the stage 3 today and the next octane level up on MHD to see if I get any retards. Found out the car comes with a idatastart autostart(bonus) but turns off when I open the door(lame) so gonna see what I can do about that

let me know what you think about stage 3 vs stage 2 as a daily driver. can't decide which to get right now

[RoughKnight]

Stage 2 sucks as I keep the car in D mode a majority of the time. It doesnt like to shift gears, some times you find yourself trying to merge with higher speed traffic in 6th gear pushing from 1800rpm, not smart at all. Looks like stage 3 is getting all the r and d. Its a bit tougher on the tranny, you can definitly feel it slap sometimes, but overall super smooth once you put your foot in it. I won't switch back

D mode in these cars sucks even with xHP, I drive in Sport all the time stg 2 and then switch to Manual when I feel like a spirited drive

That's funny, how it behaves in Drive is actually my favorite part of the tune.

I love that it holds high gears when merging, i'm less worried about it downshifting out of nowhere and catching me off guard. The car makes so much power down low it doesn't matter in the least and makes merging smoother and more comfortable. Since I am usually driving a cold car when trying to get on the highway, low rpms is my preference and letting the turbos work.

Stage 3 gives me the best of every world, no reason to mess around with the other versions and the customizable shift points, torque reduction and downshift blips are the icing on the cake.
