Thanks for showing the timing...love the detail you guys give and it's good to see a "seemingly" well taken care of high mileage S65 can still produce strong power! Makes me feel much better about having my E90 & E92 S65's!
Really like this content ... it's pure information, facts and explanation and none of the YT BS with showoff, yelling and annoying bits and pieces ... !!! Really refreshing to not have annoying people presenting stuff!
Really enjoying this series. The level of detail you are going into is second to none. I like how the videos are demonstrating where your money is well spent. Well done guys.
E9x m3 content> vs any other content! Great Great video! Could you maybe do a dyno with say 102 octane on stock DME that would be great. Thank you for the e9x m3 content!
I would definitely be interested in the 102 octane comparison, having used it during my last 2 trips to Germany. My car felt much stronger after an extended run on the autobahn.
Another great video Imran , Plugs make a world of difference, especially after 40k miles, I have a 32 yr old Volvo and it was sluggish and so i did an oil change with plugs, rotor , distributor cap and air filter with a fresh tank of 97 RON fuel CDN GAS SUCKS , i didn't gain any power it just ran smoother and i now get almost 50 more miles to a tank of gas, so it was beneficial and it all cost less than $ 100 🏎
Very interesting. I did the same on my 92 M3 this week + idle control valve, throttle actuators, fuel tank breather, road bearings $$ But it’s a must to do
Great video guys. Really well explained. I’ve got a Monte Carlo M3 with just 39k on clock. My sensible head says I should really sell to help fund a new business but this series is really making me want to keep it! Keep up the good work.
🇧🇷🇧🇷👏🏻👏🏻 Considering that this car is supposed to come with about 400hp from factory, on paper, and also with 40 NM of torque, this 150 mile e92 M3 Still got it, and is probably in pretty good shape, Awesome video. the spark plugs made such a difference.
Really interesting video guys. It’s all very well doing remaps, exhausts and intakes, but you have to start with the basics. Perfect example of that here.
Excellent video and info. Got me thinking how long since my plugs have been changed on my E92 M3 now. Can you do a follow up with a Evolve tune added too please.
Absolutely awesome video! I loved the detail from the logs and the explanation. More of these are welcome, when you guys have time. A a petrol head that works in IT, I was glued to the screen! Top notch content.
I love your channel. Very professional and scientific approach. You tick every box and met all my expectations😉. May be some day I would have a decent "M" BMW that it is worth driving down to you across the Irish sea to get some upgrades done🤞
Really interesting video. I’ve been really enjoying this series especially as one of these is top of my list next year (if car prices normalise a bit).
@@ip7590 it appears to be a combination of things; no new cars on crazy cheap deals flooding the market like normal, new cars on crazy lead tunes, people not eating out / going on holiday and not really commuting so treating themselves to something tasty. I had been looking at swapping my M140i for an OG M2. Before COVID, a decent AUC was about £26k for a decent spec’d car. The same cars now are over £31/2k. Sod that. They’re older, with more miles for more cash. E9x M3’s have firmed up too. WBAC etc are offering crazy money for cars; the offer for my 140i was too good to turn down sonics gone. I’ve bought an old 130 for a bit in the hope that prices soften a bit.
@@samcourt6228 Here in the States used M cars like an F80 M3C for example are almost 30% higher pre-pandemic numbers. Chip shortages are also creating an uptick even if it doesn't directly affect that particular manufacture as perception is reality with the car market. It's suppose to normalize come winter 2022ish, so most people who understand the issue and do not absolutely have to have a new or used car are waiting. I've seen 2017/2018 M2s with 20k miles on them selling for $55k/40k pounds...its crazy.
@@Peanutdenver yup, it’s mental hence why I’m sitting it out for a bit. Buying now seems madness. If I bought that M2 that I’ve been hankering after, I’ll end up taking a massive hit when I eventually get bored and my head is turned by something else. M4’s were plentiful pre COVID a d at similar prices to an M2, looked great value. Now the only cars in budget are the earliest examples whereas I’d want at least a 2016 car due to the revisions made. I’ve been surprised at how much I’ve the old 130 so far though. I don’t miss my 140 in the slightest.
Loving the content on this E92 M3 amazing work Imran. Can't believe my guess was also same as yours 390bhp 😂😂 once the work has been done just needs detailing and it's as good as gold 😁👌
I confirm no correlation between mileage & power for this car. I had my second e92 m3 with +100k miles and it feels more powerfull than the 1st own (low mileage 30k miles) I also loved the EDC option in daily (I sold my old one because has too "harsh" suspensions)
There is a detailed video on our channel about the intake including datalogs and dyno. The plenum doesn't make any power and has never been advertised as doing so.
Excellent informative video. Nice to understand the influence of plugs on timing. Not bad for 150 k. Shows the quality of BMW engineering and how they will last if looked after.
@@Omegaman1969 It also has ITBs, so that complicates maps a bit too, since low load/throttle will get inaccurate data from map (not sure how it is with MAFs).
@@hojnikb True it has ITBs but all 8 share a common plenum and it doesn’t have a MAF, I’m pretty sure it’s Alpha N with map compensation . I’m just curious as to why timing is closed loop ( plug monitored ) at WOT if the fuel is a fixed value . There shouldn’t be any need to vary the timing if the mixture is fixed .
@@Omegaman1969 I'm surpised that a modern engine like S65 doesn't use MAF, but i'm sure there's good reason for doing so. As for timing at WOT; plenty of reasons why you want to still adjust timing. Bad fuel, high IATs, poor plugs etc...
I predicted 398 earlier today and mentally after the spark plug change 406, so 411 was a bit of a surprise, I suppose the bottom line is that if one spark plug gets oiled up you need to keep an eye on it
Awesome! This is amazing data and I've got very interested in this evidence. Spark plug is crucial parts for engine performance isn't it. As far as I know BMW recommends spark plug must be changed every 37kmiles. What is your recommendation for spark plug change interval?
Great video! I just checked and mine were done by BMW at 157k miles (at least, the invoice says they were done...), otherwise, I would have ordered a set straight away!
Great video! Shops around my area were asking 400-500 for spark plug changed! Ridiculous anyways seeing a few videos and especially this ones confirms its not that hard of a job except the 2 far back plugs in the back near firewall! Nice video I have a high milage m3 as well looking forward to more content!!! Would u change the coil pack in the e92 or just wait for It to fail??? The 200 price per coil is draining on the wallet lol Thanks!
Do you think the plugs would make a big difference in a E46M3….???..& grant video loving the informative information that you give… KEEP up the good work…
I also asked the change interval for S65 engine spark plug (parts No.LKR8A) to NGK Japan. They answered 60,000km, it equivalent to 37kmiles. But I think it must be more frequent.
I really need to bring my e90 M3 to you. Have a air leak in the manifold and cylinder 5 misfire. It has been booked in with grosvenor reading. After watching few of your videos should have booked in with you.
Awesome video guys as always, I predicted 400 after the change of spark plugs, 411 was a pleasant surprise. I have a question by the way: If you had increased the rev limiter to 8600, would it make additional power without changing anything besides rev limit? Have you ever tuned an S65 with Schrick cams before? Thanks
I don't think you'd gain much from that, look at the torque figure on their graph. You need better breathing before you can get any real power from more rpm.
You would see a small gain just by raising the limiter yes. In our Software we can raise the limit if the customer wants, to see a little more top end.
The missing piece of the puzzle is what the IAT logs looked like for before and after. This would rule out if the ignition timing changed because of plugs or the fact the engine had cooled down and was not heat soaked
