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
