A stock K20 is good for 165 whp. What do you want to know specifically?
I was wondering why the dyno is showing so many readings other than just the wheel horsepower and torque more than anything. You must mean stock k20 as in the original exhaust manifold, intake air box and computer management yes ? I just thought 200whp was pretty low power output for a k20 with cams and a skunk2 manifold /header etc. and I’m also wondering how the other one made 263 lol
A customer had the same issue. We swapped another thermostat in it (OEM) and the drive operation temperature range was back on track. Seems there are some Full-week-Monday-production thermostat's around 🤨😜.
What part number do they have?
The vent door just allowed my blower motor under the dash to Blow hot air from the heater core instead of the air coming from outside the vent in the windshield cowl. When the heat runs it slightly lowers the ECT, but I believe it’s fluctuations are due to it sticking although it is a new thermostat. The spark plugs I got are Ngk BKR7E-IX although the Original ones are still in the engine seemingly doing fine. I will likely save the new ones for the retune with the updated fuel setup. On 92 oct pump gas we hit 100% duty @ 6600 rpm and I can already hear your forewarnings 😅 I won’t be beating the shit out of it until it gets more fuel 👍
Good choice.
At what fuel pressure?
I don't trust the stock knock system when the engine is slightly modified.
Fuel pressure right about 50psi. Maybe 51-53psi I got it as close to 50 as I could. So even just with bolt ons, and a brand new knock sensor you don’t trust it to register properly ?
This is 0.44 bar over OEM pressure of 3 bar (43.5 psi), so fuel flow is around 332 ccm. What lambda did you see at 100 % duty cycle operation?
Even then. Did you advance the ign. timing to test the increase in Knock level? At which WOT ign. timing the ECU sees a knock at high speed cam?
@ 100% duty it’s in the mid -high 12s AFR. It was in the 13s but the engine liked a bit richer in vtec, at least it felt to pull stronger and smoother with more fuel. The ecu didn’t record any knocks to my knowledge. From city driving to wot pulls in 3rd and 4th to limiter it didn’t see any knock. He told me map I had previously uploaded on there had way too much timing advance in it for idle and part throttle and it still didn’t pick up knock in the beginning of the datalogging.
Depending on the engine efficiency it should be at lambda 0.88 around 235 [email protected] % duty cycle and 50 psi fuel pressure.
Seems to be cold outside, she seemingly don't like her job 😄.
My wife loves dressing her up 😂🙄 it was pretty warm in the sun, if I ever wonder where the dogs are I just need to go look in the sunny windows lol. Thanks for the info , I probably won’t be driving much here coming up, but I will be updating the fuel system and scheduling a dyno visit when others are ready 👍
Please be aware, the fuel system control of the Hondata KPro isn't accurate enough to change the fuel injector size in hardware and software without any changes of the outcome. Injector dead times would have to be on spot for both, which is most likely not the case. The lower the load and the higher the engine speed, the greater the uncertainty. Closed loop can compensate this, but better safe then sorry and check it out.
