Nitrous with wide 02

[Big88]

When using nitrous with WB 02. Just to spool up I get a lean spike were the 02 corrects the max 25% the engine seems to flood out and quit for a split second is this possible? And would changing the 02 correction limits help this?

Big,

I don't like using the WB correction with nitrous. I like to get the engine running right without nitrous (correct VE tables, etc.) then tune the nitrous by looking at the spark plugs.

Just my opinion.

It sounds like you mean prior to N2O activation with TPS & RPM.

If it only does it when you spray, post the rest of your specs....

N20 with WB

Ok I'll try to explain what i'm doing. I'm using a 75 hp. n20 kit to spool up, Only at the starting line. Its wired to the trans brake. When the brake is released n20 is turned off. Sometimes the 02 corrections maxes out at 25%. just after release of the brake. When it does this for 2 or 3 frames on the logging the engine will die for a instant. And blows out black smoke. Will changing 02 correction limits help this?
