My Ride: BMW E91 335i
Hi njoni,

With my new trick for my MT 325ti, starting in neutral and waiting for the revs to go slightly below 1000 totally solves it for me. Asbjorn already offered to make the cold start more rich for me (with a reflash) , but as this is my daily ride and learnt to deal with the issue, i never bothered.

So i think your diagnosis is correct; but it's strange that for some cars this is an issue and others never experience it. Perhaps the cold start "friction" does differ somewhat between the cars.

greetings,
Jeroen

An M3 fuel pump alone won't make any difference in fuel pressure at the rail (which directly impacts the amount of fuel injected) if used with the stock non-M fuel pressure regulator. The extra fuel flow from the M3 pump is simply returned to the tank (in fact, I used this very fact to resolve my fuel starvation issue during hard cornering and acceleration when the tank was near or below 1/4 tank). If you were leaning out up top because your stock pump wasn't able to keep up, then the extra flow of the M3 pump would make a difference. At startup and idle though, you're not enriching the mixture simply by swapping in an M3 pump.

So I hate to bring up an old thread. But I have this exact issue. Rough cold start, and hesitation on acceleration from low RPM. I'm going to run fuel pressure checks to see if that is my problem.

I have a 330ci with nearly identical set up(Headers, no cats) except I have a TS1 and am having a similer problem. I read your other thread and I've been told pretty much the same thing as you from ESS. I am also running pretty lean at high 12 almost 13 air/fuel which I still don't know if this is correct as I am new to BMW and superchargers but I would think it should be a little lower. Definitely interested in seeing what you find out.

OP here. I think it is a good thing that this thread gets bumped up from time to time. Some of us (including myself) have not been able to positively ID the cause, so its refreshing to have new people try to tackle the problem. Please update us with your results (good or bad).

My cold start problem has gotten worse. No the car will barely start when the temp is below 47 or so. The throttle is then very sensitive and surges easily with part throttle. After 5 minutes or so, the car runs and starts as normal. Very annoying. I am in the process of checking vacuum lines.....again!

I recently read in another thread that a non SC 330 was having very similar symptoms and was able to fix the problem by replacing both O2 sensors although there were no codes....could this be a possibility??

I was having issues with cold start. Engine tended to bog a lot with light throttle. Decided to so some routine maintenance and cleaned the MAF with some MAF cleaner. That solved all of my issues! I was so surprised after having this issue for such a long time. SMH.

I'm open to just about anything. I get an EML light and a code for the throttle position randomly. Then it will go away. Its weird because I have never had that issue before. I'm still plugging away on it. I hate that Ess is not too supportive of this issue.

I feel your pain. I saw your thread and it doesnt seem like ESS is non-responsive. These issues with the TS unit are not easy to diagnose and the solution for every single case is slightly different.

At least you are throwing a code. See if you can borrow a TB to see if it is a bad sensor, also check the wiring to the TB which might have gotten damaged during the install. Sometimes badly kinked or loose wires/connections will give intermitent failures.

I installed an M3 fuel pressure regulator today. They are rated at 5 Bar. It solved virtually all the problems. The car now drives like a mad man. I will report back in a week with updates.

Do you have a partnumber and is it plug and play?

It's funny how the same problem is solved by different parts. I also have this problem and I'm suspecting crank case leak. I'll test it by disconnecting and plugging the CCV hose and report back tomorrow.

Yep, crank case leak. It's very simple test I would suggest to all owners with cold start, throttle response and AFR issues:
Disconnect the CCV pipe, plug the intake side, put a rag over the valve cover side (secure with rubber band).

That is literally what mine does as well. The M3 FPR only fixed the throttle response issue. Not the cold start issue. I will take a look at that this weekend.

ESS TS startup woes



other video.........
and guess what? ESS AJ do not want give me support about this problem (I have this TS2+ about 2 month) because he say, because I install the Schricks FI camshaft (246/252), I install an "aftermarket" part in my setup......
but...... before I bought my TS2+ and since ESS DO NOT SELL the FI camshaft , I talk with Hans asking about what FI Camshaft I need to buy (remember, since they ESS do not have the FI camshaft to my setup), and I ask about this FI camshaft because ESS say in they web page the TS2+ need the FI camshafts.......
So, I do not understand AJ, hans told me exactly what FI camshaft and specs and brand I need to buy, i bought those FI camshaft and now AJ told me he cant help me because I put an "aftermarket" part in my setup.......
what a terrible customer service from AJ......

Yeah, I didn't get much better support with mine either. They basically cited the same reason. They claimed that my headers were throwing the whole thing off.....
