Tuning does wonders

Ok, before I start, dynos in Australia read much lower than those in the rest of the world. Dynos purpose is to show the 'Before and After' results.

I've decided to give the B16B a final run before I k20 the EK9. So therefore, I had a new PFC lying around that I havent sold yet and decided to put it into good use.

I didnt want to go to the track and drags without a tune. Revving a modded untuned engine for long periods of time just isnt my style. So today I took it to the tuners to work their magic on it.

I had the stock ECU on first for a power run to have a reference graph. And then PFC tune after that.

These are the accountable mods on my car that all help get the results;

-B16B engine 230psi all 4 cyl

-Toda B16B header
-High Flow Cat
-2.36" mid pipes(+3 resonators), flowing into a 2.25" inlet muffler tapered to 2.6" at outlet.

-Comptech SRI + ICE BOX
-Hondata IM heat shield gasket

-ACT 5.7kgs flywheel
-4.785 FD

-SPOON high tension cable
-Buddy club groundiing kit

-Power steering removed

...................

On STOCK ECU: 146hp peak at hubs
Tuned Power FC: 167hp peak at hubs

My engine is tune to run 98 octane

TOTAL gained: 21hp-27hp(tuning alone)

Vtec 5600rpm
Limiter 9300rpm


HP

-Gains started pretty much from 3600rpm all the way to the extended redline.
-The biggest gain would have to be where the stock ecu stops at 8400rpm netting 140HP, the TUNED graph is showing a massive 27.33HP gain at 8400rpm. Netting at 160HP at 9000rpm. Only 7hp drop from peak.
-The increased RPM has greatly increased the powerband and acceleration.

TORQUE

-Torque gain was even more impressive with gains above 3600rpm again.
-Minimum of 4Nm to 24Nm gain was achieved.
-Where the stock ECU stopped with 119Nm @ 8400rpm, the TUNED ecu netted 143Nm. Thats 24Nm
-Peak torque difference at 6600rpm was only 3.5Nm.
-So where the STOCK ecu graph starts to die, the TUNED ecu is still pulling hard. Clearly visible after 6600rpm. Top end has much improved!

AFR

AFR wasnt too bad but had to get leaned out in 90% of areas. AFR is 13.5 -13.25 from 6500rpm.

CONCLUSION

This is to exercise how important TUNING is on a modded engine and IS one of the best well spent mod you can do. My car has definitely woken up with the tune, the powerband in real life is as expressive as the graph suggests.

I would never know what a stock EK9 would have ran on this dyno but I can safely say all those mods alone without the tune could have easily given it 10whp over a stock EK9. Tuning on top gave an extra 21HP.

Now who doesnt want that for their B16B?

The results were shocking to me because I've only ever seen 20hp tuning gains on B18, B20, K20 etc. You dont really see that much gain on a 1.6L ;)

Choice on quality parts really pays off in the end :nice:

Nice thread dude.

Can't wait to get my Hondata S300 with a WILL tune now. I have the B18C in the 9 now too so should be good.

How do you find the ACT flywheel? I assume it is a Street Lite?
 
Very impressed with the torque gains, car must pull so much better to redline. When you starting the K20 conversion? still got the ITR?
 

yes its a light weight street flywheel, comfortable for the street. Stock is 7-8kgs


Yeh it does, very surprised with gains, top end is much better.
Next year K20, DC2R selling soon.
 
Lucky you Jugs.

EK9+K20 is going to be immense.
 
Thanks for the info !

Again another excelent thread proving that ECU tunes are the best bang for your buck plus they make the drivability far greater in most cases.

Thanks again and cant wait to see the k20
 
Excellent results...just goes to show an ECU tune works wonders for any B-series motor that has breathing mods.....

Mapping out the big jump when VTEC engages & detailed work with AFR & ignition timing makes for a different driving experience...

Even on a B18 I gained a noticeable chunk of power & torque...

Very worthwhile as an icing-on-the-cake modification to optimize all the bolt-ons:nice:
 
i need to get some money together and get my b16b tuned to make my investment in the toda manifold worth it,,,,,,,,,,,,,,,, amazing gains you got here jugbugz
 
Might be worth you giving Romain @ Artech a call dude.....

Pretty sure he could sort you out with mapping S300 or eCtune:nice:
 
Great results Eric, Realy looking forward to seeing your K20 swap come together now!

Congrats again :nice: :bow:
 
Some good results you have got there! Just a quick questions concerning ECU Swaps, has anyone dyno'd a b16b before + after installing a Spoon ECU?

Thanks mate!
They also make your engine run safer and at optimum. You'll end up with cleaner oil, spark plugs and less black smoke on your rear bumper lip haha

Thanks mate!
Dude, I think one of the main reasons there was such a big gain was because of the 'Investment' of high quality and reputable parts. I'm the type who only 'gets the best ****' or 'dont buy at all' lol

Thanks Will!
Yes I'm also looking forward to that torque monster engine sitting in my garage lol
Thanks again for refering me to Jeff!

Ive dynoed a js racing ecu and stock before. There was hardly any difference. There were gains and losses everywhere. You need to get a specific tune for your setup. Small mapping tweaks = big results.
 
Thanks mate!

me too, Do it once, do it properly,, :nice:
 
Great Results. have always wanted to do this but was always scpetical on whether there would be enough gain for th emoney spent with extensive modifications.
How is the real life difference mate?
Also, i am right in saying that the modifications carried are manifold, hi flow cat, catback and induction?
:nice:

Yes.

Thats why its really surprising because its only intake, exhaust, header, P/S pump removed, 4.7FD, 5.7kg flywheel and tune.

STOCK ECU and TUNED ECU on same setup, same day.

Mate remember how I was on about how my bone stock DC2R pulls harder than the 9?

Well, now this is my comparison;

1st and 2nd gear accelaration I'll give to the DC2R because of its low end/mid range torque, but from 3rd, 4th and 5th the EK9 stumps it! Much better top end power. 5600rpm - 9300rpm is vtec band, thats a total of 3700rpm power band vs stock ecu 2400rpm. I'm also getting 27HP and 20Nm torque more at 8400rpm vs stock ecu.

It just keeps on accelerating from 3rd 4th and 5th unlike before where it struggles after 3rd gear.

Dude, 27HP for a mere $400 tune is something a $1000 toda header alone cant match.
 
thats amazing. i know from your previous that you have always said the b18 is better in everyway than the b16b. but for you to say that really says alot about remapping!
o_O

Yes theres a difference especially top end where revs really help the B16 make power. My bone stock DC2R has always been staring down on the 9 in acceleration terms until now hahaha


Btw, my engine is tuned to run 98 octane.

I just couldnt believe how much difference it makes when you mod a part of the system and end up screwing up the stock ecu results. You can see the stock ecu just wont work with my bolt-on mods.
 
i am absolutely shocked mate, especially when you own both, so your experience and answers are unbiased :nice:
Thanks for the information.
