Because the occasional hesitations are still present, plus the strange stuttering acceleration still occurs on cold starts. There's def still a problem. It's just not as severe

Fortunately/unfortunately It started up normally after removing the ECU. I still am getting a stutter upon start up, but it doesn't last. Noticed the primary o2 sensor is showing zero volts, could that have caused that issue?

You should never downgrade the software as that will just cause more problems.

i take it you have to remove the ecu and open it to find this number?

like the title says, can you? I had 2.2 a few weeks ago and updated to 3.3 and ever since have had a weird hesitation while driving. Well, today I get up and the car (04 civic si) will turn over, but the idle is super rough, and then dies. you can rev it up past 2500k once and it sounds like its ...

havin a lil trouble with this, also havin trouble getting the idle down to an acceptsble level, it stays at like 1500 and sometimes sticks at higher revs. i have bc stage 2 turbo cams, greddy turbo with 650 cc inj and fmic, bdl 70mm tb and ported prc intake mani. greddy tt exhaust with megan testpipe.

its an 04 civic sir (canadian version) with a prb kpro in it. I have innovative aluminum motor mounts and the ground has been relocated to the valve cover, was like that ever since I got kpro. the mounts however are new. Any ground wires that were attached to the stock mounts have been relocated to ...

i should also note that i tried with two different computers and both had same problem

i tried that, but it still failed, not the upload, clearing security....seems i can do nothing inbetween the laptop and the ecu. the drivers are all fine but i cant upload, i cant removed protection. i'm really frustrated....

ok, i'll start with a lil backgrund info....when my k pro was installed it had ver 1.2.2.8 (that was current at the time) now 1.2.3.1 is current. i had the 91 oct k20a3 map loaded and have put a tonne of crap in the car. i had never used my computer to upload a cal as it was uploaded at the place ...
