Nomad, good results! Looks like you got a solid 10-20 bhp through the range, and some torques!
I reckon replacing that HKS power sapper induction thing would give you some more

What is the area like under the curve?
eg You could be having 40whp more than your mate throughout the whole revband and he catches you up and 8400 rpm with a 1hp difference.
I know which car I'd prefer to be driving in.
The top line number is pretty much meaningless.

Especially if most of your use is on the road...

Hi Nomadic,
I had my car done my Mase on Friday - if you check out MB's mod thread or the original meeting thread - you will see my chart.
I'm getting 10whp less than MB, but if you comare our graphs - he has huge gains throughout.
Honda did a pretty good tune from 2004? onwards to get rid of the Vtec kick - and make the power delivery more linear.

Yep the vafc2 cannot adjust ignition timing.
It's worth pointing out that you can sort out the AFR in WOT with a vafc2, it won't learn over these settings contary to popular belief but it's not perfect.
You cannot add much fuel with it only a little, when adding fuel the ecu advances the ignition timing, when removing fuel it retarding the ignition timing.
When altering vtec it does work fine but you need to be altering ignition timing really TBH.
Overall it's not bad and does the job but does not compete with a standalone, for the price it's good.
Without going into jargon the standalones are much more tunable/fine tunable, the vafc2 adjusts the voltage to the map sensor telling it to remove fuel at x rpms, a standalone has tps/map tables etc and doesn't just manipulate the map signal alone.
This said it depends on how much money you want to spend.
I have a 2nd hand standalone DTA sitting here, which I will map myself - well with a little help from my friend
.
Good to hear people are getting enjoyment for their mods
It's an addictive/expensive slippery slope if I die tomorrow at least I can say I tried an SC.

.Fitted the SC yet?

I also agree with Gaspode, the peak figure shouldn't be the whole focus, having a load more power at 5-6000 is important for in gear acceleration. And the torque too!
At 3600 rpm you have approx +15 hp
At 4400 rpm you have approx +5 hp
At 5200 rpm you have approx +5 hp
At 6000 rpm you have approx +18 hp
At 6800 rpm you have approx +16 hp
At 7600 rpm you have approx +14 hp
At 8400 rpm you have approx +6 hp.
So very low down you have a fair bit more than me, up until VTEC we maintain the 5 - 6 hp differential that is seen at top end, but it is in VTEC that the biggest step occurs with you taking an extra 10 hp above and beyond that gained on me at the very top and bottom end.

A lot of help I hope!

Thought you were going to say you a predict a blown engine, could be your 4th prediction
.No not fitted the SC but very soon.

I'm just looking at my printout now and comparing it with your chart Mark and it is obvious where you are making the big gains with your additional mods.

Is your's completely standard other than the AEM? I'm not sure it's easy to justify over 2k (new) or just over 1k (second hand) for the intake / manifold / decat as the AEM appears to do a good job on it's own.

The only non standard things I have are the AEM ECU and the AEM V2 intake.
The other factor to consider is that mine was mapped on 97 due to a lack of 99 pumps near to where I live.
I doubt it would have made a significant difference, but may have added a few ponies here and there.
FWIW the AEM V2 must be doing something as I came out one or two hp above Man's best who has a completely stock set up, but his was mapped on V-Power.
