Knock ignition limit low and high

Post by fabiangt79 »

I having problems with this function in the kpro, whenever i do a power run my log shows me that this table ignition limit -3 degrees of timing from my actual ignition timing table.

If i run 25 on the ignition table but the log runs only 22.I tried added to 27 on that point but the next log still runs at 23.
I am trying to add more timing on my map to see if more power is made but the timing on the log does not go up.

Can hondata or anyone advise me how to offset this so i can run to my 25 or higher?

My track car setup,

K24 with wisceo CR14
High Compression ferrea valves
Kelford C cams
80mm with RBC manifold
Custom 4-2-1 exhaust with 3 inch straight thru

Even at the 5000 rpm point the ignition drops to 19 instead of my 23, can hondata or a guru can advise how to resolve this tuning issue?

I will give it a try, but how come other cars when i tune not affected by this table only our track car.

The problem is at 7000rpm the torque drops from 27.5kg/mm to 21 kg/mm at 8000rpm.

Can someone share with me why this is happening?Does not seems like is a tuning issue, right?

You may have the "use stock honda knock control" checked. Try unchecking the box and see what happens =]
