Yeah, I know they you all are trying to help me, and I am grateful, I promise, but they are almost attacking me, you just have to read the comments. If at this moment is working 99% perfect, then I will start installing all the things I got pending to install. BNR S4 Cobb 3Port EBC 3 Bar Map...

I told you in #32 since I installed new secondary O2 sensor, LTFT stopped going big negative. Since that day, I drove the car 5 or 6 days more, I resetted the fuel trims atleast 2 times, LTFT still not going big negative. Was the secondary O2 sensor causing big negative LTFT? I don't know, but...

Yeah, I know desired is not an important parameter, but if my desired AFR idling is 14.1, then my AFR idling is 14.1, so it means something I think. It looks like a crappy tune or unfinished tune, that would be an option, but I made a log like 3 weeks ago with the same map (when my LTFT was...

Thanks for answering. When I had the LTFT in -20/-25%, car has some hesitation/jerks/pulls in low rpms, now LTFT is under -6% and car feels normal in low rpms, no hesitation. Yeah, that's what Enki said, I could delete it and just hide all the voltage errors, my bad, didn't know it. At this...

Your ideas: 1- Check MAF connector/wirings >>>>> Done 2- Unplug Secondary O2 Sensor >>>>> Next Saturday I'll Can you understand I can only work on the car on Saturdays, that's why I didn't unplugged the secondary o2 sensor yet. Making tests is going in circles, okay. Desired AFR doesn't...

I was using a custom map when car started failing, but now I am running stock intake, stock testpipe, stock exhaust, only modified is downpipe is catless, but I am running a Versatuner OTS map, calibrated for stock airbox intake, and allows to use catless dp. Are you sure? Yesterday when I...

I am not having LTFT problems since 2 weeks. Problems are different deppending of the car wants, thats why I said in the tittle "My car is just crazy" Summary: 1. First all the parameters of the ECU with my custom map were bad (load, ignition advance, boost, wgdc, afr, desired afr, etc etc) 2...

If you just read the first post, you will know what's the problem and all the updates or changes that have happened in my car since I discovered the issue. You don't event have to see datazap logs, just read the text. It's not the smoking turbo, car is not smoking anymore since I rebuilt the...

Yeah I know. I will repeat my last question to see what people thinks. A few months before discovering this problem, I rebuilt myself the K04 with a good brand CHRA (Melett), but checking last WOT logs, I can see turbo is having a bad time to hold 15/16 psi, very high WGDC over 4,5k RPM. Maybe...

Yeah I know some people changes to 5w40, and Mazda USA said the problem is the crankcase ventilation and they replaced valve covers and inlet pipes etc. But the truth, talking about why I rebuilt the turbo is not going to help me atm. I trust Mazda when in the manual says to use 5w30, and Mazda...

I rebuilt because that.

By the way, a few months before discovering this problem, I rebuilt myself the K04 with a good brand CHRA (Melett), but checking last WOT logs, I can see turbo is suffering so much to hold 15/16 psi, very high WGDC over 4,5k RPM. Maybe I have not sealed properly the intake housing of the turbo...

Okay, I will do it and I will test it xD

It's a Denso one, I'll try. Unplug it and let it unplug? and what should change? AFR in WOT should be good again? :s

I am not running my custom map, I am running an OTS Versatuner map (it says its stock map but with a bit more boost until redline, so MAF CAL is for stock airbox) so nothing changed in the MAF CAL of this datazap 3rd WOT log, same map, same MAF CAL...
