Summary of what others have concluded in previous threads.

Mods in this order for the track for the 335i:

1) Tires
2) Better cooling system
3) Suspension
4) Brakes
5) Anything else to keep the car cool.
.
.
.
.
6) More power.
7) Weight watchers for car.
8) Weight watchers for driver. Not a lot of fat race car drivers.

Oh... Autos are gonna have more problems with heat than manuals.

If:
-Ambient temps are warm
-You are making more power/more boost
-you are running longer sessions

Then look into additional cooling mods (upgraded oil cool, radiator, fmic, ducting, etc,.)

If you don't think heat was the issue for the limp, read the code. Could be something completely unrelated and easy to solve.

I used to run v1 and V2 at the same track when it was warmer without issues. The only difference now is now Im stage 2. Who knows it could be any number of things. I really wish I had the code reader with me!!!

So for 12~13psi I should be looking at about 50% UT values right? Jeesh Im seeing 11 without the tune, granted the boost curve is entirely different. Should I go with an upgraded oil cooler or a bigger FMIC next? Cant afford both right now.

Thanks again

i think the two that have been implecated in my recent memory for cooling are oilcooler and radiator. but seeing that there isnt a radiator upgrade that i am aware of..

go with the oilcooler if you are worried about heating issues and limping at that track

So he was running higher temps, but he was not pushing harder than me.

Is this a recurring issue with oil catch cans? oil catch can = higher running temps?

Ahhh, limping at the track, the saga continues. The bottom line is that you CAN get a limp-free tuned car at the track.

The background story is that I've been running Procede since V1.41 and have gone through various iterations of track limping. I now have 50+ track days, anywhere from 30 degree (yes, on R-comps, yes, scary as hell) to 105 degree ambients.

The last 15 track days have been 100% limp-free.

When you compare your car to others (tuned and not), you need to keep in mind that driver differences can make a HUGE difference on limp-proneness. Data from different drivers is meaningless. A fellow instructor on this site has achieved 285+ oil temps and then had his beginner-level GF drive the car and not break 260.

I am running an iteration of V2 with the addition of the TPS sensor wire. UT is set at 70% across the board, I run about 30% race gas and my only other power mod is high flow cats. I currently run a VK oil cooler, but that's really only to keep oil temps in a comfortable place (265-270). The stock OC didn't increase my limp-proneness at all, just kept my oil temps at 285-290+

Did you have limp problems after the car heated up? You might want check two things: (1) Get an OBD-2 logger and log your coolant temps. I use the Davis Carchip to do so. (2) Do you have a slushbox?

My recommendation is to get rid of your other high flow mods and slowly add them in. An open track day is very useful for that. Run stock intake and see what happens. It may be that the intake + no cats makes for too nonrestrictive of a system and your boost is spiking out of control. I don't know.

All I know is: IT IS ENTIRELY POSSIBLE FOR A TUNED 335I TO RUN LIMP-FREE ON TRACK.

For your purposes, upgraded oil cooler first

[jeho]

so how many here are running v3 3.1 or 3.2 on a road course without issues (with stock oil cooler ATLEAST) ???

I do. So do handful of local customers who hit up Thunderhill and Infineon on a regular basis. You can also PM leftcoastman. He's active on this forum and is an avid track junky.

Sure it happened after heating up as expected. Nope, no slush box. I had issues a long time ago with the dual cone intakes sucking in too much hot air under the hood. I got rid of that and put on the UR and the problem went away. This was back when V2 was still being beta tested. As far as spiking is concerned, that is definatley not an issue. V3 has been rock solid on the gauge. I will look into an aftermarket oil-cooler for sure, and get the BT software. If those dont work, screw it, I'll get a "track" car Ultima GTR anyone?
