Paging Dr. Leask: will the real Brian Leask please stand up :)
 

Brian you here?

I'm trying to locate Brian: misplaced my Leask WUR adjustment instructions: does anyone have a copy/digital copy?? I'm not having any luck with the .Cox email address.

Mine has the upgraded diaphram for higher HP if that makes any difference.

Mark.

If you bought it through me I'll have a record of it and send you a copy. If not email me your information and I'll help however I can.

I had sent it to him directly back in January 2011. I remember emailing him a question in regards to tuning hardware that wasn't returned, back in March of '11 or so. Is he ok??

Mark

When I was having an issue with my wur last year he got back to me within a couple of days so he will respond if you have a problem.

i cant find my manual either so if anyone has a copy...
Ive emailed him lots this week and he responds almost immediately. If I had my manual I wouldnt have bothered him so much.
btw anyone know how to set cold start afrs.? Ive gotten the other adjustments down but now on cold start/early am , it runs rough with afrs in the 14.5-15.7 range......

I think he must have spam filtering on (who doesn't?). I emailed him once or twice asking if I could get replacement adjustment hardware after I misplaced the originals and got no reply.

CCP setting is the set screw on the top of the WUR. Loosen the lock nut, tap it down to lower CCP (richen). Tap down in small increments, watching the pressure gauge, slowly pull it back up with the lock nut if you go too far. I've been needing to do mine for about two years.. According to my wrench, setting the CCP somewhere in the lower end of the factory-specified range generally works best on 930's.

Changing CCP can also affect WCP (my CCP setting originally got screwed up by someone adjusting it to raise WCP on the dyno - because they didn't know there was a separate adjustment for that on a BL WUR), so check/re-adjust that separately.

Brian ran across this thread & sent me the manual: thanks Brian!

Cold start afr's: mid, mid-low 13's are best for the strongest idle with a cold engine, & produces the strongest vacuum numbers as well. 14's are too high for a cold engine.

Once warm, mid 14's. On cruise, 14.7-15.0 for mileage. For soft/mid acceleration, mid 13's. WOT: 11.8-12.0
