I was wondering what some people got from their first pull to the final tuned numbers with a dyno tune. I've got a b16 with a few bolt ons i/h/e, skunk2 IM, lightened flywheel, stage 2 clutch, and a friend is going to give me some GSR cams. So i figured I would finally get it tuned when I put in the new cams. So basically wanting know what kind of power can be had from tuning with a setup like mine. Thanks

 

So you install the cams, get on the dyno, do your run...then what? Run again? You need to change something to see any real improvement.
Pretty much the only thing you can adjust in a "stock" setup is the the distributor/ignition timing

The biggest benefits from dyno tuning depend on how adjustable your setup is...programmable ecu, piggyback unit, adjustable fuel pressure regulator and adjustable cam gears will give you someplace to start.

 

sorry for leaving it out that I'm going to use a Hondata, and thanks for your non answer to my question. So your telling me that installing those things just give you a little power and there is nothing you can do to take advantage of them and try to get more power out of them, so unless you have forced induction tuning is useless? yeah right It is kind of obvious that if you add more air to a stock motor it changes the stock a/f ratio so tuning it would be necessary to get it back to those specs.

Well....... reread what he just typed then you might understand it the second time.
look a couple posts down and you can see my dyno.

Read again, thats not what he ways saying or implying. He was saying that with out some type of tuning "tools" to make adjustments, then you won't make a gain on the dyno. With no adjustments then all you can do is make base runs and turn your dizzy. What are you doing to "add" more air?

Oh yeah, to answer the topic question, I've made over 20whp on the dyno at one time. Went a few weeks ago, set my TPS sensor correctly, had to readjust the a/f and made up 3 more whp.

 

1. I never said tuning was useless.

2. You left out the crucial detail (Hondata) and chose to list inconsequential stuff (flywheel, clutch)...so don't get pissy when you don't like my response.

Based on what you originally said, between dyno run 1, which would surely make more power then stock, and dyno run 2...what would you change or "tune" to make a difference?

OK well I guess i don't understand. I'm not trying to be pissy but i was under the impression that the Hondata would alow me to adjust fuel pressure and timing, so those are the things that i would "tune". And I only listed flywheel and clutch just to list all of my mods i know those aren't tunable items. So are you saying that tuning my car with what i have is pointless? Again, not being pissy, just asking a question. thanks

 

What I said still stands...without some form of adjustability, there is no tuning.
But you've got the Hondata, so that doesn't apply to you. You have one of the best tuning tools for a Honda.

Its not unusual to add 10 whp with some good tuning. You can make even more if the setup is grossly out of tune for the baseline run

 

oh sorry i guess i misunderstood what you were saying. I thought you meant that I needed something other than the Hondata. one more question- Do you think I should get adjustable cam gears or are those not needed? I don't plan on doing anything else to the current setup except for a small shot of nitrous so I don't know. Thanks

I can vouch for that...my very first pull on my B16...116whp Swapped cams tune tune tune...added almost 30whp

I kept my gears at stock settings up until the last dyno, where after we adjusted them and did 4 or 5 pulls (pulled in between eash adjustment) we only made up about 3 or 4 whp...then again it was blazing hot in there, so in actuality it may have been more, hell my car probably could have dynoed more. Anyway... Hondata is great if you know how to use it. Go for it
