For Part I of the story...

https://honda-tech.com/zerothread?id=546926

Turns out that the reason the numbers weren't so hot were mainly due to the fact that the dyno (a Clayton) had some serious issues. I wasn't at the dyno session but after questioning the results, I found out why. The guy tuning had to spend more time working with the shop to fix the dyno than he could spend on tuning the car. After battling with what ultimately could only be described as a semi-functional dyno, there was only time to load a relatively generic Hondata program.

So my faith in the tuner's skills are still intact...

Fast forward to this past weekend - I finally got the chance to make it out to a different dyno (a DynoJet this time) and our second attempt at making some respectable numbers.

Parts installed:
Comptech Icebox
Spoon headgasket
HyTech header + exhaust (with integrated cat)
Hondata intake gasket
Toda A cams
Spoon cam gears
Hondata s200
MSD Digital 6+
AEM FPR
310cc RC Injectors

And now for the results...

We couldn't get to the cam gears (never cut my valve cover ) so there is more potential, but I think things are headed in the right direction and much improved over the first try.

 

I thought only AEM's had that heinous dip at 4500-ish...

 

a 20hp/30ftlb dip? damn

I think that dip is just shifting gears.

 

no, i think it's from an improper vtec point

 

You have Toda-A and you're only reving to 8300rpm?

 

not bad, def needs some more tuning, and some Bs

 

Off to a good start

 

were we at kaztech together this past saturday,i had the yellow r

 

your peak should be smoother, do you have a A/F graph? The dip def looks like a shift, the VTEC dip is at 5.5K, move joor VTEC to 4.9-5.1

 

so you still have more tunning to do , since you couldnt get to the gears !!
nice

u don't switch gears in the middle of the actual run. they usually start the graph at bottom of third to redline.

yea whats with that fat dip?

 

Maybe the driver let off b/c he thought he didn't hit the button. Briefly then after realizing that he did, proceeded with the run.

they dont shift gears on a dyno its just in 3rd gear

The tuner probably pressed the button early. So it recorded the gear shift.

 

Its either your a/f is off or vtec needs to be adjusted. My bet is vtec needs to kick in later.

so you actually shift 1-2-3 and record the 3rd pull? When I was at a dyno (dynojet) the guy just put it in 3rd and started revving to redline.

 

sometimes they will start the car in 3rd and just gun it and stop...and some they will start on 2nd and rev it up and shift to 3rd and then strat the dyno...depends on the dyno operator and what you prefer...

Hey Kirk, I thought about posting the numbers I saw your car put down... but then I'd start feeling like crap again

 

you will be fine maybe remove the cat and make cam gears accessible and i am sure you will achieve your goal

 

Comments sent via IM...the runviewer files would be handy.

There is an easy way to get to the cam gears. You can cut the plastic cover under the valve cover on the cam gear side. Then install the cam gears upside down at tdc and adjust the gears the opposite of normal. It's ghetto, but it is fast.

 

You have a lot of untapped potential but you are getting there
