Hi guys, I’ve been searching and searching but couldn’t find the answer. I have a Fabspeed GT450 package on my GT4 and keep getting CEL. The codes are P1074, P0068, P2097 & P2099. Anybody have any fix for this? Have IDP and TB. Any help would be appreciated. Thank you!

Did you try contacting Fabspeed directly?

The first two codes are related to the amount of air entering the engine and the last two are a too rich mix or out of range code on the post catalytic O2 sensors.
The GT450 has catless headers and the GT3 TB + IPD....my guess is that you have the OEM file loaded, the COBB is uninstalled or your COBB AP map doesn't have the required parameters activated for the intake parts.
I would contact Fabspeed for an updated MAP....if you purchased second hand another option is to use BGB, probably the most knowledgeable people on the 9A1/GT4 engine. They can do remote MAPs using logs from the AP.

Hey Davin,
Please feel free to reach out with these questions. I hope this helps.
P0068- You need a throttle body adaption. Dealer can do this easy to fix
P1074 D0 you mean P0174 Cat inefficiency codes? along with 2097 and 2099 Lets investigate the tune on the vehicle. We would love to help out with this.

Never had any of this on my Dundon headers and tune. Dundon knows what they are doing.

My ‘friend’ got fabspeed race header and fabspeed protune and never had these problems. Talk to the tuner dude at fabspeed

Hi Phil,

I went back to HG who installed the mods. They did Piwis for throttle adaptation and CEL went away for about 400 miles but it came back last night

A new codes popped up P2272. Any suggestion?

John@Fabspeed

Looks like: This is due to a defective sensor or an exhaust. These sensors are very fragile and the smallest bump can hurt them.

Here's the code 2272 info...you may be missing the setup to eliminate the CEL when running catless, as this code is regarding ht second O2 sensor
