Re: ECU vs wideband AF Reading

What if my cat was turbocharged and decated. So basically we not really need a wideband meter. We can rely on lambda from ecu.

Re: ECU vs wideband AF Reading

It was plugged into the end tip of exhaust during the tuning. From the screen the afr were drawn in a nice smooth line. But when I do the datalog, lambda table show differently (a bit).

Another question is regarding the stock O2 sensors. Os it wideband type or narrowband?

ECU vs wideband AF Reading

I did datalog and found out that the AF reading was bit lower than the AF from wideband. Which one is more reliable?

Re: Subaru Impreza 560cc High Impedance Injector for CRZ

Thank You. Will try. Is it ok if i change the voltage value in the table? My current table are for 6v, 8v, 10v, 12v, 14v and 16v. But the data are from 10v to 15v. If the voltage is not a fixed value, then I will change the voltage and dead time value

Re: Subaru Impreza 560cc High Impedance Injector for CRZ

This is what i found; dead time for the injector

10V - 1.23
11V - 1.04
12V - 0.87
13V - 0.74
14V - 0.62
15V - 0.53

How should I get the injector opening time from these figure?

Re: Subaru Impreza 560cc High Impedance Injector for CRZ

Re: Autostop disable

One simple thing can be done, put the AC temp to 'LOW'. Autostop will not function.

Subaru Impreza 560cc High Impedance Injector for CRZ

Hi guys, I am planning to go with higher boost. I did upgrade my internal with a low comp forged piston and conrod. My current 310cc K20 injector may not be able to support the higher boost. I am trying to get a set of RDX injector but my mechanic suggest me to go with the impreza injector as it is ...

Re: My car return to stock calibration

Is it possible if I change the injector size after the tuning? or I will have to redo all over again?

My car return to stock calibration

Guys, I had my car tuned 4 month ago. But recently i found it was return to stock calibration without me doing anything. I was told by the tuner it was a 'normal' thing can happen with flashpro. Is that correct? Second thing is during tuning, the tuner put in my injector size as 370 instead of 560 w...
