Car wont Idle with SAUJPV4 - what am I missing?

I've got a modified SAUJP bin that I've got close enough to run on my new 383 build but I'd like to swap to V4. I copy across the VE tables and Spark tables but it refuses to idle and will only run with the throttle held open.

What can I be missing? are there that many changes that effect the idle/running in V4?

Re: Car wont Idle with SAUJPV4 - what am I missing?

I think i can see where the problem might be coming from here... I did some dataloging using Tuner Pro RT with the supplied XDF's and ADS files. Both the Dashboard and Tables were pegged open at ~6600rpm. IF the ecu actually believes this then that would explain why it wont idle as it would be reading from completely the wrong cell.

Any ideas?

If you are using the latest version of SAUJPv4 1026 you can not use the cut and paste method built in to TunerProRT. Check out the last page of the PDF file JP86SS includes with the download for more info.
