Most OE CS/GTS Tune

[_ts]

I'm new tuning and I'm trying to stick as close to factory settings as possible. I heard that Bootmod has "Stage 0" tunes for GTS and CS. Is there anywhere that does an OE CS/GTS tunes for the F82?

What are the other options for "factory" tunes besides Bootmod?

Bootmod has this.

Be warned though, I did this and lasted a week before stage 1.

^ This.

I am running the BM3 GTS tune and it is stupid fast IMO. I am afraid of going to stage 1 as I have already fallen prey to the "more power" game many times before.

I am prety dang happy with the GTS tune, and I think it is a good compromise. For me, the GTS tune makes for a great daily.

Either way, I recommend BM3.

Nice, I remember chatting with a DCT owner (I'm a slow 3 pedal) at a light asking about mods, he said GTS, I said stage 1, after putting a few buses on him, at the next light he said "screw this, I'm going stage one"

I know this is not what spidy wanted to hear

Stage 1 and you won’t regret it. Mostly because it’s already a lot of power and you probably don’t have the right tires to grip to go too crazy.

I disagree with the Stg1 recos.

Stg1 is clearly not OEM. No OEM has an epic torque hump in the midrange that then falls off a cliff.
The GTS/CS off the shelf tune from MHD/BM3/etc feels just like the OEM cars. No giant, stupid torque hump. They feel linear and powerful. Undoubtedly the Stg1 is more powerful yet, but it also doesn't feel OEM.

Having owned a F80 CS and owning two GTS, I could give a flying fuck whether a Stage1 car beats me in a pull. A Stage2 car will beat the Stage1. A Stage2+E30 will beat the regular Stage2, and so on and so forth until you drive a Frankenstein. The drivability of the OEM tunes is unparalleled.

If OP is a OE+ kind of guy, then the GTS/CS map is for him. Boost levels approved by BMW, well within limits of the turbos and the rest of the drivetrain.

Another vote for bootmod3 from me. Not sure what year you have though. Newer ones need a bench unlock and if you need a smog check you will have to “stock and lock” it to pass which will require the bench unlock again.

Im in the UK and have just gone for BM3 Stage 1 multimap with the addition of VSRF Induction Kit and Charge Pipes fitted at the same time.

The induction noise is superb and im playing with the BM3 map settings via the BM3 wifi OBD to get the set up I want.

Need to understand more on the right map for the 4 slots for when im on Shell V Power vs. Standard fuel.

So far, im very impressed with the gains and it feels very smooth indeed.

This is indeed a pain in the ass, but if you choose mhd which also has cs/gts maps, it will generate a stock file itself that you can pass emissions with. No need to relock, bench unlock, etc

I live in California, so passing emissions is needed here. Why do these tunes make it so you can't pass emissions? Can you go further into depth about the differences between MHD and BM3 in this regard?

I'm far from an expert, but from what I tell:
CA checks to see if your software is OEM. If it is not, you don't pass, even if all the monitors are ready.
Both BM3 and MHD are able to 'flash to stock', however, the BM3 'stock' file gets flagged as a fake while the MHD one passes. There's a long thread on this in the forum somewhere, but those are the cliff notes. To get the BM3 to seem stock requires you to lock the ECU again, and if your ECU required a bench unlock to be flashed the first time, this bench lock means you have to do that again to tune.

I'm surprised BM3 has not corrected this yet

GTS is best OEM tune imo. Wish it was part of the stage 1 multi map on BM3. Much preferred over the CS tune within that pack

Can you elaborate on this?

[SYT_Shadow]

Both on bm3 and mhd, you don't need to buy a map pack to get the stg0 and stg0+ maps. They are free with the license

Bm3 is fantastic. I’ve switched back and forth between the tunes for this platform multiple times; my favorite is cs+. Love the powerful delivery and the car rarely feels overwhelmed. Stage 1 though is epic, especially in 3rd or 4th gear on the freeway. Truly, amazing what a light, safe tune can do to these cars.

So if you were to do GTS, should you worry about crank hub? Ik another one of these questions lol but would appreciate a genuine response.

Do a search for CALID (calibration id) and cvn (calibration verification number). Basically the ECU has a checksum for the programming. The output of that checksum(CVN) needs to match a number pre-programmed by the manufacturer (CALID). If those two don’t match, you flag on their system as having a tune.

Well, the gts level of torque was approved by bmw.

Despite everyone's desire to stick their head in the sand, it's pretty obvious spun crankhubs are closely correlated to high torque levels.
When you read the Crank hub threads there is post after post of 'I spun it after two laps with a stg2 tune'.


I tracked my F80CS with suspension, BBK, slicks etc with the stock crankhub for 3 years and 200 trackdays, and never had an issue. The OEM M4 GT4 racecar also doesn't have an issue.
CS and GTS both have the same torque, the GTS just carries the same amount for a little longer to improve the top end power.

Hey man, thanks for the response. Would you reccomend any supporting mods for a GTS tune? Perhaps downpipe or charger pipes and intakes?

I wouldn't at all, and that's the beauty of using a OEM tune - it was designed with all the OEM parts in mind. So the downpipes, intake, spark plugs, are all good!

I wouldn't do any mods to have a GTS/CS tune. Maximum drivability, no gapping spark plugs, no weird fuel, you just use it as if it came that way from the factory

Say if I was to add on dp for the sake of sound, would I be able to remove CEL still with a GTS tune using bm3?

Yes. The rest of the BM3 functionality is not affected. Same as if you use MHD
