0411 Segment swap issues 80E

[1bar]

Hey Everyone.

2000 Camaro 6 speed with 12212156 base tune. I matched up the OS and segment swapped in an 80e tune. I was able to get the trans to work well but always had a U1000 and C0181 code that threw a Service Vehicle light. I can’t pass emissions with these two DTC’s popping up.

I also tried a 12212156 base tune with a 60e and the codes disappear but once I segment swapped in the 80e tune it throws the codes again.

I’ve tried a 6.0 and a 5.7 truck/van 80e tune and all resulted in the same issues.

Any ideas?

Thanks
Glenn
