Jb4 Codes

[Caden Yeatman]

Hey! I occasionally run my E30 map 6 from Jesse and I just switched back to map 1 on 91 octane. I recently checked my codes, as I do often because I’m catless and any new codes won’t alert me, and I found these. The exhaust and catless dp are normal but the rest are new. Any ideas/concerns on what could be wrong? I’m gonna clear them and see if they come back. Thanks in advanced!

They all look like just catless codes with ethanol and the throttle manifold codes some cars get them randomly from the jb4. Doesnt look like any issues.

121201 - TMAP Active while engine off is a strange one but, could just be from you scanning with car off.

Thank you Jesse! I appreciate it!

Hey! So I cleared the codes and the fuel one went away but the tmap code came back along with a new code:
191C02 tank ventilation system: malfunction

I’m getting my ecu unlocked and I’m switching to bm3 soon but any thoughts on what the tank ventilation system malfunction could be? Thanks in advanced!
