    ZFG Racing Tune Review

    remember it's a custom tune! Just gotta ask and be descriptive about what you are feeling and how you want it to be different which you did! If you need more changes just submit more requests. Sent from my SM-S938U1 using Tapatalk

    Loud clunk when launching E50 tuned 26’

    It's driveline slop. Ask your tuner to soften those shift points if it's too much. Sent from my SM-S938U1 using Tapatalk

    Spun rod bearings

    How much were you losing on average? Seems like a "normal" amount is 1qt every 3-5k miles which seems like a ton. Sent from my SM-S938U1 using Tapatalk

    Yeah don't run them low on oil! Been a rash of people sending me logs with 30 psi of oil pressure until 60 mph... gotta check those levels often. Sent from my SM-S938U1 using Tapatalk

    Steeda Or ZFGR Tuning.

    Depends on the power level and how you take care of it. The quicker faster harder shifting in sport Motors actually way better for the transmission long-term than the softer mushier shifting in normal mode. Remember the softer the shift, the more time you are spending slipping the clutches in...

    Ask me to soften it up then if you don't like it. Sent from my SM-S938U1 using Tapatalk

    ZFGR but I'm a little bias! Sent from my SM-S938U1 using Tapatalk

    There is a recall on lift pumps, messing with the settings to make that go away isn't a good idea just get the pump replaced. Sent from my SM-S938U1 using Tapatalk

    ZFG Racing Tune Review

    It is a different shift strategy cold. In sport mode below a certain tempature it won't even attempt to us the aggressive trans tune. Then above a certain temperature but below about 145 degrees it's using different parts of the tables. After that it's all in the correct tables. You are looking...

    What am I hearing?

    Meh not really, what's crazy is seeing how many different ways ford chooses the slice the cake in terms of the logic that's available vs what and how it was used. One type of ecoboost will use a table one way, the next won't even use it all. Granted on the newer mg1cs036 and mg1cs055 they really...

    What am I hearing?

    New ecu new, turbos, different oem calibators on the dyno cell, new strategy all together who knows. I'm sure that they had their reasons or that's just how the calibration of the sensors was done. That's why I typically don't modify the sensor calibrations but making more sensitive should help...

    What am I hearing?

    So here is the log, you can see were are logging all 6 cylinders for knock and the overall average as it's using average mode at this RPM. You can see KOM is 1.0. Spark is 15 to 16 degrees. the over knock correction is 2.6* meaning it's adding timing over the borderline base and each cylinder is...

    What am I hearing?

    Send me another log with video so i can listen with head phones as it doesn't really come through on the phone speaker, and I'll look at the actual knock thresholds to see if your calibration is different than others, I don't typically go into that but do know it's changed over time. I also want...

    What am I hearing?

    I would still do the ic the upsides are way more than the down. If you leave the shutters I started keeping them closed at lower loads like factory to help that. And the stock boost until warm up is actually their Factory as well but we do a couple things to hold it back a little more than...

    What am I hearing?

    Right, and that was my point earlier. The tune is essentially totally stock in the load range that he's hearing the noise in. The stock tune will do the same thing once kom reaches 1.0 and the load conditions are met. That doesn't make it right but also it shouldn't really going to have any...

    What am I hearing?

    There is a big difference between the naked ear can hear in the car and what the knock sensor picks up. When I say audible knock I'm referring to what can be heard in the car which is above and beyond what the knock sensor can pick up. In order to get to that point you typically have to be maxed...

    What am I hearing?

    Send another log then, the only other thing I would questions is the reliably of the knock sensor data on your car. I've never seen issues with knock sensors before in terms of them being bad or not picking up knock but there is anyways a possibility of that. Sent from my SM-S938U1 using Tapatalk

    What am I hearing?

    Some kind of rattle but doesn't sound like knock. Knock is more of a lose change in a pipe sound. As I've started multiple times though your logs show 0 sign of actual spark knock and very minimal spark correction, and a I explained before the tune uses stock spark borderline tables and stock...

    ZFG Racing Tune Review

    In our tune, that lightly loaded area is going to be the stock borderline spark table and cylinder pressure limit no need to modify those areas tuning wise. Sent from my SM-S938U1 using Tapatalk

    ZFG Racing Tune Review

    To be honest that's why we do normal mode with a different transmission profile compared to sport mode. I don't expect anyone to drive in sport mode full time, I wouldn't even on stock tune. To keep up with the power levels and get the good ets the trans tune has to be fast and firm the more...
