Hondata

Hello, I have a problem in my car with closed loop. I see that my car is runing very rich (modify basemap), and I want to see what happen with my closed loop.

I do a datalog with my s300, and see that the car is runing very rich, but the problem is that after 5 min to run, my closed loop is blocked at 1%, with no correction, can somebody tell me what happen? S300 iusse?

I put here my .cal and my log. Can somebody help me? Look at 5:20, blocked closed loop.
Thanks.

get it tuned. a basemap is not a tune

Hehehe.

I know that I need to tune, but I want to understand what happen there.

My car was runing good, but I change my IM, TB and 310cc injectors and become very rich. I try to tune, but was impossible, if I put less fuel the engine go off. Then, I change again my injectors, and put stock, But I have same problem, very rich.

I want to understand what happen with my closed loop, and have one more question. Can the s300 read narrowband in open loop? because I read 14.7 in my wideband, but narrowband is usually in 2.4 volts, wich is a lot of fuel. And I change my stock narrowband and read the same. Now I'm waiting for a friend lends me his wideband.

Thanks again.

Do you have a wideband?

Yes, I have, but I think that is broken, becouse in this map tell me 14.7-15.3 runing slow, but is not true, is runing very rich.

Today I start with new basemap, dont have problems with closed loop and the car run fine. Tomorrow will try again with my wideband.

I have a similar issue. I'd like spunksters input. My closed loop disables every now and then. The only thing I can think of is it's having to correct too much from thr tables. I know in most cars the way a car throws a lean or rich code is the fuel trims being above or below certain amount. For example if your trim exceeds 15 it will throw a lean code. If your trims are -15 it will throw a system too rich code. Hondata doesn't have that. But seems to just throw a p0130 code and it deactivates the closed loop. Anyone else have experience here?

What is your long term trim?

I stopped logging long term a while ago because it never read. But that was my beginnerish stages. I'll check it out on the way home. The s300 doesn't learn values does it?

please start your own thread for this.
