How do TS owners control (manage?) supercharger oil?
please show me how and when to check etc!
The oil level should be 10mm lower than the center of the SC shaft center. Normally there is no need to add/check oil on the TS unit.

Since i have the 8psi, and you programmed it for TS2+ 8.5psi, isn't it already running richer, or is what your talking about something else.

Yes, at WOT, but not during startup. Some cars require us to dial in the mixture a little bit richer during startup than emissions ideal in order for it to run 100% smooth the first seconds of operation. On newer MS45 cars you can even feel that a stock car is a little "jumpy" when cold since it is running quite lean to reduce emissions and heat cats quickly.

Am I the only one having problems with warm starts? If the engine is warm, and I shut it off, say to drop my kids off at camp, and I try to restart within 30 seconds or so, the car won't start. It seems as if I'm not getting fuel.

Ok thanks i will send it in sometime soon,, so my car is MS43, so then if you program it richer for cold starts it will get rid of those hick-up starts.

Well, since it has warmed up, I have had very few problems with the cold start. The idles creeps up around 1200 rpms during warm up but besides that, there is almost 0 stuttering.

I still want to get my DME exchanged for the new software as well.

Asbjorn, I sent you an e-mail a week ago and haven't gotten a reply yet.

This is not normal at all and I have in fact never heard of this before. Do check your fault codes, fuel pressure after stopping the car and also idle vacuum and report back to me. You can also send in the DME for analyzing to see if we can spot the problem. At the same time we can also update the DME with the latest programming.

I have not received any emails from you, you are welcome to ship in your DME for a free update whenever you want. Just mark your name and order number on the DME shipment.

I have this 3 sec stumbling too. It does it when the engine is cold (sitting for at least 6 hours or so).

I have replaced the fuel filter (FPR comes with it on 330)
I have replaced spark plugs to Bosch Super 4

No change in cold start...replacing the filter just made my car quicker that is all as it was filled with black stuff lol

My guess is that the fuel pressure is falling too low...the fuel is leaking somewhere...or the fuel pump is just not hardworking enough for these higher flow injectors.

Mine starts at 1100rpm in very cold and after ~half minute drops to ~700rpm. super smooth idle, better than before imho. I haven't experienced any rough idle since the installation 12000km ago.

Have you checked the idle valve?

I have, and it idles fine just that for the first 3 seconds of cold start it hesitates to go up to warm-up RPMs. But, it never stalls even at -38 C that we get here in Canada

I can confirm that my fuel pressure after 5-6 hours it drops to zero PSI. When this happens the car hesitates to start...even though I let the key in ignition to build up pressure as indicates in the Fuel pressure gauge that I kept it mounted on the fuel railing. I seem to think that after the fuel pressure is lost air is getting in the injector and then the car hesitates to start until the injector or the railing is filled up with fuel upon the injector being triggered to open when cranked up.

In other words, either injectors are not good, or the fuel railing is not tight enough against the injectors at the top fuel feed.

I will see if I can find a way to detect the leak (if it is the side against the railing as the side against manifold should only trigger a too lean code).

But, I had it torqued right when I installed the injectors and I lubricated the rings to slide completely in.

It is most likely the fuel supply components (pump/regulator-filter assembly).

Try the regulator-filter assembly first as this is cheap and nice maintenance to do anyway.

Once the O2's fires up after a little while the current DME settings will adapt in at once, but during startup it is running straight off the software and MAF/temp input without any feedback.

Do check for leaks first as you might have a little leak somewhere, if all is sealed then you can update the ECU for free to the latest TS software that runs a bit richer on startup.
Well Asbjorn, the latest ESS TS software didn't make mine any better, has anything been sent to me Asbjorn like we discussed in our e-mails? also to all that have this problem is it like mine you see in this video?

Most of the time my starts are like that, although the stumbling is slightly less than on your video....but yeah, its about the same.

Same here although it's not consistent. Sometimes it starts up like in the video, sometimes is starts right up and then stumbles, and sometimes it almost starts and idles perfect (although if I touch the gas before it warms up good it will still choke).

I have a new fuel pump and filter/regulator. Fuel pressure and manifold vacuum look good. Fuel pressure was dropping off faster than the spec in my Bentley which was what led me to replace the pump - now it holds pressure much better.

My car also has a slight hesitation on abrupt throttle tip in, especially below 3k rpm. Don't know if you guys also experience that or not.

At this point I'm considering that my vanos may have failed. I have a vanos unit on order but it may be a few weeks before I receive it and get it installed. I'll give an update as soon as I know if this makes any difference or not.

mine starts fine...the pulley skreaches...and revs a little high,..then settles right down...no real issues

but yea, i cannot get in it and go after it sits (usually days or weeks between drives) or it will hesitate and stumble...

Spartanwarrior :

Yes, I will send you the ECU with the cat detection switched off along with 6 new injectors.

TxZHP04:

Please send in your DME for the earlier MS45 ZHP TS2+ software version without MPG correction as this is more stable.

Stuart:

Did you ever get the updated idler pulley bracket/pulleys and the new TS drive pulley? This should remove any noise from the belt drive.
