Took apart the FMU to check to make sure its a 12:1 disc and its not, its 10:1 (don't ask, just need help fast). I already have the complete recalib kit and a 12 disc which is the biggest (1 size bigger then whats in there), Now all the discs have a ring that they fit inside that you install the disc with.... BUT the 12 disc which is basically the whole size of the FMU does NOT.... do I use the same ring with the 10 disc (which the 12 disc does NOT fit inside) or do I use no ring at all?

Please help asap thank!!!

 

NM I installed it with no ring, just the disc and new diaphram... it has to be the way its supposed to go in.

For the small effort it would take, why not install the 12:1 disc alone, install it in the car, and see what happens?

 

Nm I got it setup, I was running a 10 disc which explains my lean condition all these times... after a race with some stupid accord ricer on the freeway (it had viper stripes on it and stickers up the ***) I checked my plugs and all the flaking was gone and the plugs were nice and brownish.... its good to have fuel.

FYI the 12:1 doesn't need a ring, its just the disc and diaphram.

 

How can you tell a difference - can you post a pic of a 10:1 and the 12:1 disks
