So if i do lightly tap the peddle the AFR and STFT do change back to within 14.0-15.2 and 12-16% . I can grab a quick log of it. Justin sent me a update map with more fuel at idle and it still leans out and locks at 16 AFR. What i don't understand is that randomly it will have moments where...

I sent hot idle logs out after driving and doing pulls I recently got a revisions with more fuel at idle and slightly higher rpm and it still pegs its self in the 15 range and stft locked at 24 Tuner is Justin freektune

Update, installed the MAF straightener and re flashed the tune took it on a 30 mile drive and same thing at idle. Though I will say it is a lot more consistent AFR wise. My next step is probably going to be testing again for air leaks and or other recommendations. Maybe the motor might just be...

ill order one up and see if the issue proceeds to happen or goes away... will be back once installed and ran

The intake dose not have a straightener but has been on the car now for about 6 months and was tuned with it and ran fine, only things I've recently added is a external FPR and the jmf port injection manifold which I've gotten a touch up tune for

The issue ended up being the turbo seals were shot and also excessive blow by from rings caused oil not to drain down into the pan from the return line new BNR S4 V5 with a OPR helped solve this issue

To update this post for those wondering the answer to my question, you don't have to take out the ITFPR. You can simply crush the regulator down till it achieves 80psi. From this i drilled holes in the basket to try and keep as much fuel the basket as possible. Also drilled the top hat and added...

Reaching out to see anyone has gotten some type of resolution from my current lean idle issue. The issue is very own minded it will come and go and seems to happen at first start up cycle and with some slight throttle input for a sec or two it will come back to its desired target I've taken some...

Hello all i am in need of some insight on my split second controller. Currently i am running a 6th port set up and will be switching over to 4 port here in the future. My current controller on came with two ID pig tails and am wondering if i can Y in two more injectors to the current two on the...

Did you ever find out what was the issue causing the STFT to be locked at +24 having similar issues and have tried all things stated above

Did you ever find out what the issue was for your case ?

Did anyone find a solution to this thread without needing the specific Mazda tool to pull of the pinion flange in order to service a leaking pinion seal ?

Definitely better then the first log you sent, you started leaning out at the end of your first one and in this one it’s actually staying true to target tho you are maxing out your fuel which it being in the 90s you could maybe pull some E out of the tune to bring the duty cycle down a bit, what...

Even to run a return line back to the tank you’d still need to rework the carrier to get rid of the ITFPR? I’ve seen some guys run just a line straight back off the external FPR and put a bulkhead on the top hat and drain the fuel back into the basket but they never mention anything about taking...

Does anyone know if you have to take out the in tank fuel regulator when going the return style method or do you still just keep it in and regular what’s being sent back to the tank via the regulator on port system ? Looking to make my 6th port system return back to the tank but am stuck on this...

Do you think it really maters to have that bracket to ground the wires instead of bolting it straight to the trans ?

The world may never know....

Hello everyone wanted some insight on what you guy may think is going on, my s4 has been smoking on decel after installing a jmf & xs manifold I have a vented oil cap with a damond pcv plate and and a duel catch can set up running at vta with the appropriate check valves also have a 4an oil feed...

did you open the end of the bolt facing downward into the CHRA ? has the issue been resolved still or was it another band aid fix? mine is also smoking under decel and coming to a stop or even sometimes low rpm with some engine load.

I’m looking for some more info on wideband failsafes like a AEM or Innovate. I know there is another thread on here about fail safes but I’m looking for how they are installed and how they are set to work and help prevent ZZB. Currently getting tuned on a 6th port set up and need a safety in...
