This was the first dyno, with basemap, Uberdata. Look at what happens when it hits VTEC.



This was the last dyno made with Uberdata. Softened up the line before VTEC, but it still goes absolutely heywire after VTEC.



This was with an AFC tune and VTEC set at 6,500rpms. =(

What the hell is causing me to make absolutely no power at all? SiR II motor, T3 turbo, 6psi, 450cc injectors. Couple tunes with Uberdata, switched to AFC.

 

That first graph looks like absolute shit.
What size is the t3?
hows your ignition? stock? been replaced (plugs wires cap,rotor,etc) lately?
After it's been cleaned up a bit it looks as though your engine is missing a bit in the higher rpm.
Whats your timing set at? how much timing retard are your running @ full boost? how much boost are you running?
Your afr looks like it could still be cleaned up a bit.
Whats your base timing set at?
Whats the rest of your set-up?
Vital info.

 

T3 .42/.48 50 trim
Stock ignition, new plugs 2 step colder gapped to .030. Cap and rotor do look a bit chewed up.
Timing is stock, with boost retard feature on Uberdata. We attemped to retard and advance the ignition timing several degrees and got no power from it.
Boost gauge reports 6psi full boost.

Rest of setup: Rank1Racing manifold, TiAL 38mm wastegate w/ 7psi spring, custom 2.5" downpipe, recirculating dumptube, 2.25" catback, stock cat, custom 2.5" charge piping, Johnny Race Car FMIC, Walbro fuel pump, 450cc DSM injectors, 1g DSM BOV.

 

That first graph looks like a fmu set-up the way the afr dips drastically when it switches over to the larger lobes.

who's doing the tuning? I've never seen a graph look so chopy.

BTW usually rasing the vtec cross-over will result in a smoother transition.
When I was running a sfc/fmu/310's and stock cross-over I would lose about 15whp. I bumped my x-over up to about 6,000rpm and the transition looked like your second chart....I would only lose about 2hp...

regardless your afr looks like it can use some help still

 

Mac Autosport did the tuning.

The first graph was a base map, no modifications. The second map had some work done below 4,000rpms hence it looking a lot smoother.

The car feels really smooth transitioning... I can't even feel VTEC anymore.

 

Part of your problem is that tiny ass turbo. I ran that same exact turbo on my b16 and made a max of 199whp @10psi tuned. Well I would hit 10psi by 5,000rpm then drop down to about 4psi by redline. That turbo is just to small if your looking to make any serious power. I gained 27whp alone by just switching to a t3t4OE .57 trim .63 a/r. Then worked on the tune a little more and got up to 248whp @9psi.
I'm not to fond of the jrc intercoolers, they arn't the best for flow...
I would replace the cap and rotor if it looks a bit chewed up....
So are you running 7series plugs or 8 series plugs? You should be more then fine with 1 step colder (bcpr7es-11's) I've never needed anything more then that.
are you running 92 octane?

 

The turbo holds boost all the way to redline, and I think it's more than adequate enough for what I am trying to do.

Running 7 series plugs. I was trying to get 6 series but had no luck.

Running 91 octane, but I am at 6,000ft so that is like 93 octane at sea level.

 

lol, I've yet to feel the coveted "vtec"..
My power jumps drastically once I switch to the larger lobes, but I still have no idea what the vtec rave is all about...
I even tried driving my buddies gs-r w/bolt-ons to see what everybody was so excited about...still nothing....(I swapped my motor and turbo all at once so i've never sriven my car w/the b16 N/A)...

 

You can hear it mostly... feel it a lil bit. I dunno... regardless, I still make no extra power with VTEC, and in fact my power drops. Which is completely wrong... I should be making peak power above 7,000 rpms, and not below it.

Tomorrow I will change the dizzy cap and rotor, check the plugs, and... I guess that's pretty much it as far as ignition goes. *shrugs*

 

How much power are you shooting for?
Sure it'll hold 6psi to redline, but your not going to make a ton of power with that turbo. 200whp is about what you'll see out of that turbo before you start heating the charge temp up a lot. You can run more boost but the charge temp is going to climb pretty fast.
Stick with the 7 series and gap them about .032 or so.
