Review/Dyno/Vid: Hondata K-Pro Fully Tuned CT-E Supercharger - Auto 5AT - 265hp/199tq

[ProjectTSX-N54]

Good review and amazing numbers for TSX. I am looking at K-pro also. Listen I want to know more about the VTC and tuning. I want to know how much that will cost me. Any Ideas? I have N/A with i/h/e

Nice numbers, Kenny. I am sure Doug will get a solution ironed out for your K-Pro issues. I plan to add K-Pro + 10psi pulley next year, myself (along with water/meth for cooling). For now, I'm just enjoying her as she is.

Sounds like a jet engine spooling up, just more high pitched. Nice number, hope you get the other issues worked out. Too bad you don't have a 6MT, then when it stalled you could roll start it and keep on going :P

[DAYTA]

Sweet numbers and great write-up, bro!



I think everyone with K-Pro is having idle issues (myself included). Ultimately, it could be an inherent problem with the dual-ECU setup.

The problem occurs when larger fuel injectors are added (I'm running Bosch 725cc). A larger nozzle means it's more difficult to control flow rates at a lower fuel pressure. Consequently, it's more difficult for the ECU to maintain a consistent flow at idle versus under load. The RPM fluctuations you're seeing are the result of the ECU trying to correct itself.

Typically, the problem is remedied by increasing the idle RPM point. However, as Kenny mentioned, the idle and IACV sliders don't work because the stock ECU is still controlling idle RPMs, meaning we're stuck with the engine trying to maintain the stock 750RPM idle point.

What my tuner did to partially alleviate the issue was to increase idle ignition timing by 1-2 degrees in order to bump up idle RPMs. It works occasionally, but more often than not my idle is still erratic (particularly with my lights, A/C, and stereo on all at once). It'll bounce from anywhere between 550-800RPMs.

I personally haven't had my engine stall/shut down, but it has come close quite a number of times. This is just speculation, but I think some of it might have to do with AT cars usually being in D (partial load) when stopped at a light while MT cars are in neutral (zero load).

I agree us K-Pro owners should speak to Doug about this issue and try to get it resolved. However, I'm not sure if it will be possible...

Thanks for the props everyone! It has been a long but fun road so far.

No fuel upgrades. I didn't need anymore fuel for my setup. Even Hondata with his setup didn't need to upgrade his fuel setup.

Church Auto charges $350 flat rate for a tuning session. They tune all cam angles and part throttle too.

It will cost $185 an hour or $350 flat rate if they need more than 2 hours.

Yeah, Hondata said they are looking into it. Who knows how long it will be before they develop a solution though. If they can find away to control the idle speed and IACV duty in the stock ECU, then maybe they could reflash it to account for the larger injectors.

I'm glad to hear that you are not having stalling issues Dayta. Are you still running the crushed fuel pressure regulator that you had on with the CT-E Stage 1 kit, or did you put a stock one back in?

Hopefully this will all get resolved. We'll have to see though. I will definitely keep everyone updated if I hear anything from Hondata.

i'm not very good about all this.. but, i m seeing you guys have some sort of thing to tune the supercharge?... (Bosch 725cc? for example)

If i only add on a supercharge .. no Kpro. Besides supercharge and the parts itself.. i'll still need some more parts to add with the S/C ?

the sc kit from CT works and its all you need to make the blower work. other add-ons just improve the power of the s/c.

[TSXDET]

Awesome writeup. Can't want to get mine tuned. I hoping for those kind of numbers.

No, it will work right out of the box. You will be limited to 5 psi though. That's the only kit that is CARB approved and Smog Legal in Cali, so that's the only kit that CT-E currently officially sells.

If you want more boost after that, you'll need K-Pro, tuning, high boost pulley, and bigger fuel injectors.

[Tsx536]

Also, to update the stalling and idle problems. I'm currently working with Hondata to get everything fixed. I've received good customer service from them. Once they heard of my problems they began working on it right away. I'll keep everyone posted!

My car will suddenly stalled when speed reduced, it was so dangerous cause mostly it happened when I off the hwy ramp, and the steering wheel seems locked or hard to counter. My other problem was the idle is rough, it's similar but totally different. My idle would be high (like 1500-2000rpm), and when I stop @ a light, my idle can drop lower than 500rpm. Gas consumption went up as hell, a touch of the pedal will cause the car to go open map, zoom past 4500rpm easily and head into high rpm (might sound/feel fast but not necessary).

Of course, I don't have SC or K-Pro. But hear what you said lead me to think one of the reason to cause the car to stall is the sudden increase of air-flow. I'm guessing it's sucking in too much air, and it might give the flap a hard time to back to its original position when you are decreasing your speed? I don't know. All I know is it happened only when you reduce your speed, it never stall when you floor it.

Chuson, how did you adjust the idle RPM using the throttle body? Do I need to remove the throttle body and adjust the screws from the back side?

Which direction will increase the idle?
Does moving the throttle plate closer to the intake side make it idle higher, or moving it closer to the intake manifold side?

Hopefully, Chuson or anyone that has swapped out their throttle body can elaborate on this.

Thanks!

Hey Kenny I was just wondering. Does this mean that your car is no longer smog legal in CA?

Also, how bad is the torque steer if there is any?

[jrhonda]

Was this the same day I was there? Nice numbers! I got to ride in this car and what he says is true!
