I was wondering if anyone could point me in the direction of the most current hardware/software required to connect to a 7727 via USB/Serial and at least download all relavent tuning data. I'm not looking to modify the tune right now, just download whatever changes have been made in spark/fuel tables. I bought a '90 Vette this past summer thats been upgraded with AFR heads/Comp roller/SuperRam. Whoever did the work obviously did some tuning on the ECU to match, because it runs great. I just want to see whats in there.

I've worked with Megasquirt and Holley EFI, so I have basic familiarity with this stuff.

Thanks,

$8d mask downloads can be found on tuner pros site or gear head efi.

 

I think what you are looking for is Moates Burn1 to read the PROM. He also sells a header to be able to read the PROM via the Burn1 without removing the PROM from the MEMCAL (HDR-1?).

From there can then use TunerPro to view the contents of the calibration.

You can download the latest version of S_AUJP here supporting $8d and be up and running quickly. The included XDF file provides access to every item in the calibration along with descriptions. The provided ADX logging of all activities.
