The super sports are a lot softer of spring rate. I’d expect the rubbing issues to stay there if he went with the super sports or possibly get worse.

A little camber, roll the fenders, stronger springs. Call it a day

Keeping these springs, going to roll, 10mm spring pads and a bit more camber. Should be perfect.

Sounds good to me. Keep up the good work!

With the usual S54 swap without the PWM fan, its best to put the MSS54/HP into Z3 chassis config which uses a dual relay setup like the E30. But with Garys solution or the one that Airventdisplay.no is coming out with, make sure your MSS54/HP is set for the default E46 chassis config.

So how does the variable E46 compressor work without the Can Bus?

[R3Z3N]

That's what Gary and Airventdisplay.no's solutions take care of. It's not all CAN bus though, some is on the K-Bus. Just know, with the magic of programmers and hardware guys like the 2 mentioned, we can have working AC, and can utilize the E46 variable compressor.

So without it the variable compressor will not turn on correct?

[R3Z3N]

Variable Compressor or not does not matter. Without either of these 2 boards there is no compressor control. But if you have the variable displacement compressor, it will run as such. You see that the wiring from the ECU to compressor goes through a relay first? This means the ECU does not and can not vary the signal to the ECU except by switching the relay on and off. Ours is mechanically controlled, not electronically controlled for it's variable properties.

However with the MSS54, you have other niceties such that under WOT (wide open throttle) the ECU shuts off AC to regain the parasitic draw of the AC system.

Gratuitous shot after I detailed some of the other rides.




And one more shot of the E30.

Can’t wait to see Klaus in person..

Can’t wait to see Klaus in person..

Haha you have seen Klaus naked!

[bradnic]

Ha that’s so true.. you know what i mean. That cluster man wow
You should bring it buy so I can get him up on my scissor lift ;-)

Definitely will!

Long time no update. Life getting in the way of the car, too much travel not enough time home.

So the car is running and driving quite well actually. The rubbing problem in the rear was fixed by going from 3mm spring pads (less than the stock ones) to 10mm pads in the rear. Now that there is no rubbing put miles on it so the computer is adapted and then we will tune and dyno. Pretty much everything is done now except the AC. Still having some issues with the Canbus. It's at the shop now and they are working on getting the AC up and running.

[bradnic]

Can’t wait for a ride in this beast :-)

Needs a CM5908+BT once the AC is sorted. Working a trunk sub and 5 channel rear amp setup too.. Will bring a car by later this summer

If you can not get the CANboard working, airventdisplay.no just finished the PCBs for his variant which will also integrate for full MK60 support with or without EWS/IKE/IKHA. Just some soldering and testing to do. As to the AC dryer to E46 AC pressure sensor adapter, still in progress here in SB, the shop has been busy.

Thanks Justin, they may be giving you a call this week for help. The guy's name is Alex, although I think we have it figured out now it just taking time to finish.
