Help me get a safe A/F for the dry shot...PLEASE
Help me get a safe A/F for the dry shot...PLEASE I had my car tuned today and it picked up alot of power over the stock tune. The A/F was 12.5-1 and we added timing, leaned it out here for hp, added fuel there for torque, and the end result was a 13rwhp/25rwtq increase. My a/f now sets in the low 13's.
Before the tune the car would compensate for the dry hit by spiking to low 14s, falling to 13.0 at 4500 to 12.0 by 6k.
Now with the new tune which is obviously waaay better than the stock one...well on motor at least...it will NOT get outta the 14's. We tried all kinds of **** but it didn't do much to it to bring it down to a safer level. We also couldn't find out how to find out the injector duty cycle on the Tech II.
I thought that there was some way to tap into the MAF table for the N2O without hurting the tune while N/A. Any and all advice would be greatly appreciated. I want to get back on the dyno and get it safe where I can use the juice again. As for now I am gonna put the bottle on the shelf.
Thanks in advance

I just did a tune for an Nos guy..100 shot..
A/f NA was 12.7~13.0
sprayed h ejuice and A/F richened up on its own to 12.2~12.5
pretty evenly across the board..
If you tune MAF properly then you will not have to retune for the juice...

Would you mind going into a little more detail? I adjusted the maf table (added 30% to the stock values) I also adjusted the Fuel/Air multiplier table in the higher Map readings, I would have thought that adjusting both of these would have brought the A/F level down, but neither made any change in the A/F what so ever...
Thanks for the input so far guys. Yeah, Danny was tweaking on it but we never really saw a change besides it smoothing out a bit.....still too lean. Keep the info coming guys, and thanks again.

all I did was recalibrate the MAF with the wideband using AFR error%... once it was reporting teh correct things its all good..
add some juice and it will read that as a change in density and the MAF will add accordingly...
because its also a colder charge it will be richer than plain old warm air...so your dry shot should richen up slightly when sprayed through the MAF
and a 100 shot is ok to leave a pretty healthy amount of timing in there..IIRC we puled out 2* which doesnt mean jack **** for NA horsepower..comes out to be about 5HP..LOL and then its safe timing for a 100 shot...
