I removed the OMP since the Haltech will not run it. My question is how much

premix do you guys run with the pump disabled? I've been putting 16oz bottle of

Marvel Mystery oil in every fill up, which equals about 1oz to 1gl of fuel. Is that

to much?

thats what you want to run 100:1 ratio.

Thats what I figured. Its just been smoking alot lately. I guess my freshly rebuilt

BNRs are leaking!

it sometimes will smoke a little with oil in the fuel.. doubt its ur turbos

turbovr6

smokes all the time? or first start of the day. my omp is gone, brand new engine, single turbo, and she smokes a bit on the first start of the day, for about 30 seconds, then it's clear sailing all day long

Well it smokes until it gets warm on most cold starts especialy the first of the day. Also smokes the first time or two when I get into boost, maybe a little build up from the premix? I think the question I need to ask is, will running rich cause blue smoke, rather than black, cause of the premix? I know its running rich till warm up, a/f being between 10.8-12.0. Im pretty sure the coolant maps are a little rich.

last time Iput mmo in my Vert it would smoke after being off for a long while, till it warmed up..

12.0 AFR is pretty lean isn't it?

Not at idle, right?

I mean the a/f is according to where my idle is at. At 820-850rpms the a/f is around 11.7. From what I have gathered the a/f should be leaner during idle/crusing/light load than it is during WOT.

BTW, my a/f readings are coming from the Techedge wideband o2.
