Thanks. The car works but only after I uploaded with the older version of Kmanager

My question is, now that I have downloaded the calibration from the ECU onto the computer (*it didn't work when uploaded with 1.3.0.0, but work when uploaded with 1.2.2.7)... is it safe to say I can upgrade my ...

I've been using the 1.2.2.7 to tune my car. Once it was all said and done I put the tune aside for at least a year.

Today, I did the following
1) Upgrade my Kpro software to 1.3.0.0
2) Downloaded the calibration from my ECU (*Which was tuned under 1.2.2.7) - It did say something abt the tune was ...

yup, i have energy suspension motor mount inserts and raise the idle to 900 rpm because of it... this was all during the time I was N/A.

It wasn't this noticable until I went superchaged... everytime that rpm dips and the ignition rises, it send chills down my spine with the rumble

How come I never feel this "rumble" when it was still N/A? Even though it was doing it I never noticed it until after I went supercharged.

Is it due to the bigger injectors?

I have a idle issue which has been bothering me for awhile. When the car sits idles (set at 900rpm), it will occasionally dip to 830-850rpm range and the car will rumble and the rpm will climb back up to 900rpm.

I played with the slider ...

So I should do a cruise datalog and then use lambda overlay to increase fuel where the blocks suggest?

I'm having some misfiring issues under cruise conditions. It's random misfire, and sometimes involve cylinder #1,2,3,4 as well.

I did some reasearch on the board, so how does S. Term fuel trim play an effect on misfiring under load (*during cruise)?

I see that you can fix these lean misfires by ...

I found this in one of the reply's HONDATA gave in a misfiring thread at idle:

Welcome to Honda's ignition controlled idle speed. -2 to 10 degrees ignition timing is normal at idle - the main table is not used.

so that means it's normal for ignition to jump to 10 at random and rpm will dip ...

You'll make more power with krpo vs. reflash... that's if you have it tune correctly. Every car behaves differently with differnt mods, the reflash was meant for a "one flash fits all", so the reflash won't be as aggressive as it would be if you tuned it for your car. If you tune it on a dyno ...

It's funny, because this only happens at idle after I put the car under WOT. If it's normal driving it wouldn't do this.

Also, I also got a question regarding to the idle.
At idle (set at 900rpm), the car will dip into 830-840rom for a quick second and you can feel the car hesitate for a bit and ...

btw, i checked all bolts and nipples and there is no vaccum leak

I have a question I would like to ask...
I'm currently supercharged at 11psi, and everytime when I go wide open throttle and then come to a full stop at idle, the rev will bounce up and down between 1000rpm to 2000rpm continously.

I can get it to go away by either driving it off or shutting the car ...

hondata?

Dyno break down...



As you can see, the transition at high cam from 30 to 50 created a power loss... it's noticable when you look at the power curve once the cam angle got to 50 degrees on the high cam.
