Dry shot a/f ratio
How can you keep your n/a air to fuel ratio legit, while having your air to fuel ratio much richer for a dry shot? How do you correct the injectors to inject the proper fueling while spraying?
To make an example lets say:
5.7L n/a
13.0:1 AFR
-100 shot
12.0:1 AFR (target)
How do you reach the target while maintaning the 13.0:1 AFR all motor?'
Thanks.

Anything you guys have learned to do with your tune? I'm trying to fall inbetween the above example. Keeping a decent n/a air fuel ratio but also, having that tad bit fatter air fuel ratio for the spray. This is thru the maf so I figured there has got to be a way to do this with a tune. I have HP Tuners so if you could give me a few ideas, I'd appreciate that. Thanks.

Use your fuel adder vs IAT. If you log both you'll see temps go lower on the spray. What this will do is add an additional multiplier on top of your wot PE multiplier only on the spray. I am really time limited but that's the basics of the two tunes in one concerning fuel ratio. Ther are a couple more things that can be done using this extra multiplier, and I'll try to get back to ya later. The year of your vehicle may not support this additional multiplier? It comes zeroed out in HPT.

Sorry sportside, it'll get a little involved. I am setting up my bike for the drags and keeping car ready. If this is holding you up in any way, say so, and I will get right to it. Sorry for the delay. Or, I could just high light things and go from there? I am backed up on E-mail/PM questions also.
