Cams and the ESS TS2 and TS2+ tunes

Someone compared the TS2 and TS2+ tunes and found no changes in the fuel maps.

I think it was davew?

I was wondering if anyone knows specifically what is actually different between the tunes at all?

The only hardware changes when going to TS2+ is a slightly smaller pulley (81mm vs 83mm) and the FI cams.

I'm already running a 79mm pulley and the AFR and ignition timing is right where it needs to be.

But I want to add the FI cams, can I swap them in without updating the tune? Or will it run like crap?

You can just put them in.

For the best results, a retune would be on the menu.

So it will run fine, but the VANOS or something just isn't optimized for the new cam profiles, or something like that?

I asked my tuner about this exact thing.
His response was there is so much adjustability in the Vanos that even huge overlap cams can be tuned for.
It will not hurt to just stick in the cams and drive but a tune will optimize the power gains.

All good.

I'll be looking forward to the dyno.

I've found a 264 in 248 out but with the duration being that fat apart would they work?

There are no differences in vanos/camshaft related maps between TS2 and TS2+, but there are a lot of fuelling tweaks through the TS2+ file:

Injection time at idle speed, cold engine, vanos active
Injection time at idlespeed, cold engine, vanos active
Injection time at part load, cold engine, vanos I
Injection time at part load, cold engine, vanos II
Injection time at idlespeed, warm engine, vanos active
Injection time at part load, warm engine, vanos I
Injection time at part load, warm engine, vanos II
Basic injection time

My previous comments have been that ess, contrary to their advertising, do not tune the actual cam shaft VO etc, or "optimised vanos maps" or similar.

i would save your money and custom tune , car should adapt with TS2 tune in the meantime

Crazy, so the ONLY thing they really change between TS2 and TS2+ is the injection time? And only for idle and part throttle. I'm surprised.

As terrible as ESS is to deal with when it comes to their tunes, and in light of this, it makes no sense to use their tune.

I was thinking there still might be value in the fact that they allegedly spend "50,000+ miles" tuning this kit for daily drivability and top performance, but I think thats horsecrap. It definately does NOT apply to the MS45 because the tune I got from them had to have several iterations of corrections for the AFR to be right (and the only thing out of the norm was my M3 fuel pump).

Agreed. I'm on my 7th update from them. My first tune was so lean, the car overheated on the first run on the dyno. The timing is still all over the place. Looking at the numbers from my last tune, all he did was retard the timing.

Good thing I have the data logger and your assistance in converting the O2 voltages to AFR (many thanks!) or it would of cost me over $700 in dyno time alone. Even after all this tuning and moving to an 83 mm pulley, I'm only at 286HP on my best run...
