You just moved to CSL firmware, right?

Both the physical CSL dipstick and the CSL FW call for more oil. If you started getting that light recently, it might be because of that and not a failing sensor.

You can add more oil or mess with the tune:

I've been quietly thinking how odd it was that it started happening right as I did my intake! I'm like 5/6 to the max line. I assume it's supposed to come up when low? I'll add more oil since the CSL dipstick shows the engine is okay for it.

I have shifter parts for you to scan btw.

What brand for oil level and temp sensor since hella doesn't seem to be in circulation anymore? Has anyone tried newer gen bmw sensors?

thermostat, o-rings and coolant...sounds crazy high

That’s what I had thought.

[Getgonz]

Ya I dunno, looks pretty easy to me.

They said there’s some internals in the housing that you can’t get to that could wear out and leak. I’ve never heard of such a thing, I feel like that’s quite high as the job seems fairly straightforward and doesn’t involve a whole lot.

That seems overly excessive for a thermostat replacement. The housing shouldn't need to be replaced.

So my thermostat is acting up and stuck open. I understand the process in getting this swapped out however I don’t have the tools or space at the moment to get it done. I’m also getting married in the coming weekend so I don’t have the time on my hands anyway as I haven’t done this work before. A local shop quoted me $1130 for the thermostat and housing, just curious if anyone thinks that’s a rip off?

[Getgonz]

Ok will do. Thanks

Basically is it worth getting some software and means to continuously try to dial it in? Or is simple enough to just have someone else do it. I had someone “dyno tune” one of my cars in the past and it was no better than what I had done before I brought it there. I ended up reading learning a bit, and pulled more out of it just driving around and messing with the laptop. I’m not planning on doing anything else to this car in the power category.

Just get an HTE tune once your done installing all the parts on the car. A Dyno tune with HTE will really help.

Ok so this is lazy AF but. I’ve got my e46M3 , Eventuri carbon intake and CSL style box, euro headers on the way but not planning on much more in the air fuel category. Do I get a setup I can keep tuning? Or do I just bring it somewhere have it dialed and leave it. I’ve been dialing an old injected car for years depending on changes and obsessive nature.

If I understand correctly the Eventuri setup you're going with retains the MAF sensor right? If so with that and the euro headers you're ending up with something functionally pretty close to a standard Euro M3 setup, but with US fuel. Given you retain the MAF I don't think you really need to worry about mixture tuning as the MAF will measure accurately. Likewise I don't think there's going to be much difference at WOT either given the airbox still has the intake diameter restriction of the MAF sensor. I'd have thought the main thing would be adjustments for US fuel, but again if you run high enough octane then that's probably also not far off and just needs to account for winter mixes etc?. I'd have thought that a one-and-done tune based on the Euro software would be the way to go here? (someone correct me if I've missed something though).

I think Getgonz is asking whether to

1. Get the car tuned once with the plan of leaving it alone for the foreseeable future, or
2. Plan to continue tweaking the tune over time and select mods/tune accordingly.

(Getgonz please correct me if I'm wrong)

Ah got it, Both will work depending on his plan and budget etc etc.....

[IamFODI]

No idea what you just said......BUT Get it tuned professionally by HTE for example.....
