Ok thank you !
In my mind, "fuel trim" was including those IAT /ECT corrections.

In this thread http://www.hondata.com/forum/viewtopic.php?f=12&t=14503
i was asking if I can have some fuel trim in open loop since i don't have a stock o2 sensor.
Hondata's answer was : "There cannot be any fuel trims in open loop without a stock O2 sensor."

But I tried something yesterday.
I was ...

I changed my injector from stock rsx injectors to Rdx 410cc injectors.
I changed the value in the kpro : Injector Size from 310 to 410, but I don't see any change in the values in the Fuel table. Is that normal ?

Why is he having 8 knock count at idle ?

Ignition is not affected by closed or open loop fueling.

ok, Thank you !

Since I don't have a primary o2 sensor (only a wideband) i'm running open loop.
But i was wondering, if the fuel trim vs IAT still work ?
And is the ign timing trim work vs knock ? in open loop ?

You cannot see the fuel maps in duty cycle %.

Use the map tracing to see where it is reading when looking at your datalogs.

I"m using that very nice feature already. But since i'm doing that part time, if i'm looking the datalogs next week, i may have forgot if i already did some change to those ...

I have a question about fuel map and the duty cycle %.
How can you see the fuel map in duty cycle % ?
Or can you see the value from fuel map in the datalog ?

Because it's hard to see what value in fuel map has been modified vs the logs.
Sometime i'm not sure if i have already modified the fuel map ...

I need some advice,
Since we can't see any hp gain on the street, how do you play with ign timing ?
Raise it until it knock ? or you keep the "stock" ign timing from base map ?

Any different technique for part throttle vs Wot ?
Any input is welcome

Follow the troubleshooting in the Helms manual for those error codes.

I did it.
But in the helms they said to verify those fuses

No. 14 OPTION (30 A) fuse in under-hood fuse/
relay box.
• No. 2 B LAF HEATER (20 A) fuse in under-dash
fuse/relay box.
• No. 4 ACG (10 A) in under-dash fuse/relay ...
