ESS Supercharger differences

[FD3S]

old mate gets out of his GT3RS like he's been for a sunday stroll through the park..

Now with the ZR1 even them will be feeling weird...

About the ECU tuning there has been also a guy in zpost with nickname comic, I think French too, that tuned a custom ECU for the Z4M by putting custom aluminium velocity stacks . He has managed without SC, to tune it at a very high number of HP.

Interesting news regarding the SCS Delta on a Z4M, that would actually sway me towards a CSL airbox as I wouldn't have to run a crappy alpha-n map...

Also great for a supercharger conversion as could get the car live mapped in the UK without having to rely on a generic tune.

You get a CSL air box, you /WILL/ be running an Alpha N map.

But that's exactly his point, hopefully with this ecu you would be able to run a map sensor and then not have to use alpha-n like we do at the moment.
No one uses alpha-n any more on e46 with csl box as the far better way of tuning is with the map sensor as used in the CSL. It would seem it's not possible to run this map sensor with our ecu, well at least I have heard of no-one doing so.
Alpha-n is just a bodge really, that said it works very well on my car and I'm happy enough with it. Keen to hear of anyone using this ecu though..

Their is quite abit more to it than a bodge, this tuning cant be compared to a limp home mode preset value to get you home type thing. Speed density tuning is a great great way to do things, particularly im FI, and not just this vehicle , some very high end applications.

Sure, I was being slightly tongue-in-cheek, but there's no getting around the fact that the correct way to map an S54 with a CSL airbox is as BMW did with the CSL using a MAP sensor. The alpha-n 'fix' (which was used before people worked out how to convert MSS54/hp ecus in normal m3s to run a clone of the CSL dme) is simply not as adaptable to all conditions hence the myriad of complaints you will find out there about various well known tuning companies versions of S54 alpha-n maps, in particular relating to WOT scenarios at low revs.
As an aside, I am speaking to ESS about the possibility of running the MAP sensor with our MSS70 ecu, hopefully it should be possible but the whole architecture of the MSS70 is very very different from MSS54 and also really quite different to the MSS60/5 used in the E9x cars.
