.kal and datalogs

Hi Folks,

Am running some new cams.

Did 2 short runs with some problems, hence didnt manage to WOT.

I couldnt engage vtec past 5,800 rpm.

I did 2 runs, one with o2 enabled, the other with o2 disabled

Here's the KAL file:

Datalog with disabled O2 sensor

data log with 02 sensor enabled

You don't have vtec set to engage until 6000 at lighter loads. It does show it engaging, but since you are not WOT you may not hear or feel a difference.

problem is when revving to 5800 6000, i can hear the higher cam coming on then it sort of pulls back and my rpm drops ??

First major problem: You have error P0341 disabled. If you ever need to disable this error, there is a problem with the cams, cam timing or sprockets. Given that you've just swapped cams, it seems like the first thing you should do is to check the cam timing.

The most accurate way to check the cam timing (without using lots of dial gauges and a degree wheel) is to bring the engine to TDC #1 using a rod on #1 piston. A dial gauge is good, but by carefully rocking the engine back and forward you get close by eyeball.

Ignore the marks on the cam sprockets. Look at the sensor wheels at the end of the cams, and check that they are horizontally aligned with the parting line on #5 cam cap.



The reason it is better to use the sensor wheels is that this will pick up problems with the cam sprockets and camshafts which the sprocket method will not.

thanks dude for the advise.

For error P0341, is this disabled by my tuner or it is disabled if hondata sense there is something wrong with the cams setting ?

shd i enable P0341 now and do a datalog ?

Yes, P0341 should always be enabled. Check the cam alignment first.
