Cosworth Plenum: The Good, The Bad & The Ugly
Larry has my tune on his PC I believe. I don't have a problem sending him my EMS for adjustments. The Z is not my DD. Making these remote adjustments would only represent a bandaid until a proper re-tune can be done. And in my case, it is just a little bit of help to prevent unnecessary engine and or sensor damage so I can drive out to see him.

Randy does not have the software or the cable to do so.
In about 3 weeks we will be releasing this new Can display that will have the ability to do VE tuning right on the display!!

I am concerned a little bit about a new noise I think...A very light whine (barely audible) which might be an endcap just pissing out just the smallest amount of air when boosting. I checked the hoses and had to remove the allen bolts that secure the Cosworth to get to the very last end cap bolt. You all know which one I am referring to. The one that is covered up by the Oil filler neck. Unfortunately I was almost done loctiting them all and came upon this one. I was forced to lift up the Cosworth Plenum to access the last bolt. After Loctiting it, I re-assembled everything and torqued it down to spec. All good.
Upon initial assembly, I used a very thin layer of black RTV for the endcaps (as Sharif had recommended). I had to re-open 1 side to fix a rubber gasket I damaged and cleaned it out thoroughly before re-assembly. I guess I'll have to check again and take a close took to see which side is leaking and re-do that 1 side. Luckily working on the Cosworth makes removing the plenum a breeze. Only 6 allen bolts and 2 nuts...Nothing like working on the stock set-up. And the engine bay has so much more free space it seems, overall just a cleaner way to go.
Oh and by the way, has anyone broken off that metal tab that is apparently glued to the passenger side rear corner of the CF end cap? Mine just snapped off. I hope that is not where its now leaking from...I'll have to take a closer look. I am hoping to just use some Gorilla glue and stick it back on. It's only purpose for me is not major - I could certainly live without it, but it supports my Boost Controller solenoid so nicely. Any advice on repairing that is appreciated. Not sure if Gorilla Glue will be able to withstand the heat of the engine bay. Open to suggestions.

I think I'll just use this stuff to fix the bracket:

Here is a little taste as to how well it works: (enjoy)

i wish that bracket would come off my plenum cleanly. Its not being used.
Also, loctite doesnt work until its dried. So if you ran the car before it dried, the bolts could easily back themselves out again.

^did you get a response from a particular tech or just a general email like techsupport@cosworth.com
What do you have Danny? Passenger or Driver side? In good solid working condition? No cracks or blemishes? Cosworth told me that they have blemished replacements avail now and a slight back-order on new clean ones. (backed-up 3-4 weeks.
