Yeah that’s what i was thinking was .015, but i don’t want to get one that will still make it run too rich then have to buy another set, the jets are like $12.xx for a set of 4.

3 thousandths is alot when dealing with that though, but what is your target AFR on the spray, 11.5-12.0? if your deep in the 9s now, id rather put a jet in that might put it into a high 10-low 11.0:1 rather than going too small and going WOT and hitting 14+ and taking the chance at going too lean and melting something.

See that’s what i don’t know…I don’t know what AFR is good while WOT spraying. Should i be at 11.5:1 or around there?? or is that still too rich? I may just buy the .015 jets and see where i’m at, because that is 3 thousandths which is a lot like you said.

you would want to be in the high 11’s ball park.
are you going to be fine tuning with the EMS too?

I can’t justify spending $600 getting it tuned. I’m going to have to do the best i can tuning it with the EMS.

It’s not worth it given gas costs and toll costs.

WORD.
Your willing to build a car…but not finish with a tune… thats like installing carpeting , and not vacuuming when done.
Thats a car that should be well into the 12’s.

I can’t afford a dyno tune right now, but i can tune it with the software and EMS as best i can.

i didnt mean have us do it but of course that would help, i thought you were doing it yourself. if you wire the nitrous button to an aux input on the k pro then you can add or take away fuel at the injectors as needed for the shot.

your guy in NYC tunes k pro for under 500? k pro has 24 complete fuel and ignition maps, 4 for each of the 6 angle settings available. compare that to your normal 2(1 fuel and 1 ignition), or 4(2 fuel 2 ignition for high cam/low cam) for basic vtec motors. not to mention you have to find the optimal cam angle as well at each rpm, and theres 2 more maps for that.

Not sure the specifics. I can find out though.
How many hours does it take to tune one of these? I assume you guys have starting maps and can fine tune from there.
