You're MAF signal is very messy.. Do you have an intake on the car or is it stock? MAP signal is also a bit messy.. Sometimes this can indicate a miss fire. You're also knocking right from the get go.. . A misfire will not affect the MAF sensor readings, only the O2 readings (and then as a result a...

Can you take a similar log but also log the control module voltage?

You need to service/replace your HPFP (or the internals). ASAP, because they are damaged or the pump is clogged. Also, the boost control system is not working on your car, one of the lines going from the turbo compressor housing to the wastegate actuator or from the wastegate actuator to the EBCS (o...

Nope, no tune changes required for what you did on the car to fix it. If the STFTs get to 20 then most likely you have a vacuum leak as you suspect.

Hey Darko! From my experience you can use any of the tunes from the existing database made for a race pipe. I know that in the tune description is stated that the factory DP is required, but since the secondary cat is the most restrictive (and the OEM downpipe is good for well above 300bhp with the ...

I guess as a work around I could unplug the rear 02 and disable the dtcs, that will ensure it has no influence at all on anything Yes, we actually do this on some cars, especially on those which we cant to use leaner mixture for cruising and low loads. With the secondary O2 still connected you can'...

Ok, I just saw you posted a log, but why would you use forscan to get it when you have versatuner?! Download the attached dashboard preset, open your versatuner go to Dashboard -> presets -> import and then load the newly created preset. Then take a WOT log in 3rd gear from 3000-ish to 6000-ish rpm ...

Do you have any idea where is the problem?do you want a log? Yes, add a log. Also my car has fmic(max 450hp), tial qr, hpfp autotech internals, 1 step colder plugs with 0.7mm gap, 76mm downpipe 200 cell cat, 70mm custom exhaust, custom intake (oem diameter) and custom tune. In my log with 3rd gear ...
