Closed Loops problem.

[Hitokiri]

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.

get it tuned. a basemap is not a tune

[Hitokiri]

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?

[Hitokiri]

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?

[jaygeezemail]

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?
