People with a tune, how is traction?

[Capt Crunch]

So I've got a (power wise) bone stock competition M3 with 295s at the rear and the traction control is cutting in fairly regularly as my tires are getting worn. I'm looking at getting a tune but I really don't want to have traction control ruining everything in 1st and 2nd gear. I realize I can turn everything off, but this is a daily driver.

So those with tunes, did it turn your car into a >70mph only car? Or will a new set of Michelins + tune have the power get to the ground?

The tires help. The tune actually makes the car feel fast. Honestly a stock M4 is underwhelming. You shouldn't have any traction issues unless you want them with the proper tires.

I'm running a stage 2 ots map currently

The car still drives normally, it's not as if you have to treat the gas pedal as an on and off switch. Just use the appropriate amount of pedal input for the given situation and you'll be fine .
I highly recommend a tune.

I like a linear tune with low torque and only increased power from say 5k on which doesn't upset the tires too much. I just can't mash the throttle indiscriminately in second or it will break free. I'm still able to get full throttle from about 40 on when tires are warmed up.

I'm on the stage 2 E30 tune with 275 size PS4's. Outside temp's are in the 40's where I live right now and if I do a 40 roll I'll get some slip but nothing crazy and once I get into third it hooks. If I do like a 30 roll though I'll spin a lot once it hits boost. However I recently coded my MDM mode to the Euro spec so it allows more slip before it kicks in. With this it dead hooks at a 40 roll without cutting in at all. Only time traction control kicks in is in the same situation I just said where if I floor it in the bottom of second and it hits boost. With you running 295's I'm sure you'd get better traction than I do too. However I would definitely recommend looking into coding your mdm mode to the Euro version

I have one map with limit power for the first 2 gear.

The S55 engine ecu have a lot of map table with pover an torque editable for evry single gear

Some tunes let you control boost by RPM/Gear to help with traction, or you can get a custom bootmod3 map

I'm running JB4 stage 2 with DPs (and upgraded chargepipes for some insurance), and have the PS4S, and it's better than it was stock with the PSS. I think the upgraded rubber is doing a lot of the work here lol

I didn't have any issues with the bm3 CS+ tune and 285 PS4s rears. I'll bump up to stage 1 in spring. Hell, it had stock runflats on when I bought it and I felt like those did fine in straight line acceleration too. The PA4's I'm currently running do way, way better than I thought they would too.

The traction control on these cars is incredibly invasive. Even in MDM it will kick in at the slightest hint of wheelspin. I made it a couple months before I got sick of it and started turning it off any time I'm not on the highway.

[f80er]

These aren't race cars and a tune doesn't make them one. Just drive it like a normal human being and it will be fine.

I swear I wonder how some of you are able to put your pants on in the morning without asking for advice on how to first.

Stock run-flats.... on what car frame?

Sorry, should have specified BMW approved run flats that dealers seem to love to put on off lease cars.

Oh, wow. Wouldn't let them come near an ///M car, especially from a BMW dealer that purposefully installed them. AFAIK, there are no "BMW M approved" run-flats.

You must be fun at parties.

Lol that's my line.

Honestly man you aren't new to modding cars. I think remember your sn from audizine or nasioc? Either way why would you think a OTS tune would cause traction issues?

I believe the question was asked in the context of how even the stock tune has traction issues. Given the significant increase in torque from a stage tune, OP was asking if it's worth it. I can relate because I've asked myself this question many times, and decided it wasn't for me. I'm constantly fighting the TC on upgraded tires on stock tune.

Ideally I would keep the midrange the same and get a little more pull after 5500 RPM, but the amount I drive my car combined with how much I'm fighting TC as-is made me decide against it. I prefer as balanced a car as possible, where I can always hammer on it and hook, rather than an overpowered mess that is only good for highway pulls but is slower than stock at street legal speeds since TC is always cutting power.

No traction issues on either the stage 1 or GTS bootmod3 maps. Very linear and smooth. Running Michelin PSS factory sizes. If you are fighting traction on a stock tune, then you are doing something wrong.

There are. I don't know if they're specifically "M approved", but they'll put the Pirelli's on. I honestly just assumed they came on the car stock. Because why else would anyone put them on?

Good to know I'm infamous (from NASIOC)! I worry about traction issues because 80 additional ft-lbs at 3000 rpm is a 20% increase.

I am doing something wrong; I have worn rear tires. I don't want to have the same traction experience that I'm having now on new tires.

Don’t bother with a tune unless its stage 2 and you will need some version of a crank hub mod. Most off shelf stage one tunes just spike the torque curve. No one likes to really talk about it but the f80 becomes quite a handful with the nannies off combined w/ stage one tunes.

[John Tanglewood]

I don't agree with people saying to go stage 2 or don't think about it.

I had full bolt-on stage 1 ESS tune, and I was faster than 99% of cars on the road, and it was a complete blast.

To combat the loss of traction I put on the widest Pilot Sport Cup 2's that I could fit on the stock rear wheels (295s). This made such a tremendous difference that I would recommend it to anyone having a similar issue as you.

The stock Pilot SuperSports that came on my F80 couldn't even handle the stock power, so that alone should tell you that you need to make a change regardless of tune.

[rocklobsta1109]

I have the Alpine tuning Stage 2 (GTS like tune) which is probably equivalent to a mild stage 1 tune from the competitors. Its smoother power delivery than stock with no torque spike and can put power down very well in 2nd gear and up. Highly recommend Alpine's OEM like tuning options if your not going for a full kill mode tune.

[Fuel-It!]

I use the JB4 boost by gear to reduce boost in 1st and 2nd gear which dramatically helps with traction. They just got S55 JB4 anti-lag working too which should help with traction for rolling starts.
