[Anar1988]

Hi guys. for begening i am sorry for my english. I am far away from USA once i ordered Subaru BRZ 2018 from auction in USA. So i received my car and start engine and drive it. So car worked with missfire. We went to Subaru service. we changed Spark plugs because there were in all blacked. We changed all them same model were on the car. Then engineer checked coilpackes, fuel injector. there were no problem with them. Then master checke the Delicious Tuning D-box and there were none blinking green light. So he opened it and see it it must be replaced with new one. So we contacted Delicious Tuning from e-mail and Instagram. And we ordered new flex fuel kit. So we receive it and installed by our master and we see blinking green light. We started the car and drive it with online computer diagnostic. So master saw that after 2000rpm to 3000rpm car again work with missfire. So with new device our problem not fixed . So we find another engineer with HP Tuners app. And on the way master checked car on drive and see that there is some problem with AFR. At missfire moment 14.5AFR goes down to 9.5AFR and begins missfire. And now i am living log file for who can understand and read it. https://files.fm/u/jt9fmqm7k

So guys i need very very much your's HELP. i cant drive car with this problem. i am afraid damage the engine.

What modification have you done to your car? Have you flashed a tune from Delicious? The box is not going to do anything without a tune associated with your car. A base tune will get you close but you will need to send logs to Delicious to nail down your car. (Or Zach at CSG hint hint!)

All modification had done in USA, and how ever i know it is Jackson racing super charger installed and Borla exhaust and speeddesign mainfold. Delicious had put map, then tuned it. Fuel pump had changed to DEATSCHWERKS DW300C pump. DEATSCHWERKS 700CC fuel injectors.

Have you flashed a tune from Delicious? -- I had bought car from auction. that is why i dont know what were done.

Pump change is nothing. We’re the injectors changed after the tune? That would be your problem. If yo do not have access to ethanol then I would remove the D box and just get a tune for the fuel you will run.

Was your car advertised as running? If so can you reach out to the previous owner? Or was it bought as is? At which point you'll have to do your own trial and error. Unfortunately i can't see your logs from this computer, when you are idling what are your trims like?

Dump the flex fuel kit and have it tuned for the fuel in your area.
