Great Job
Hi Phil
John from California here. Fantastic work. I have a 1992 USDM EG33 in my VW Vanagon Syncro. I have been able to read data from my ECU consistently with a purchased RS232 to TTL converter. Of course my ECU is located in a completely differant spot and my wiring harness is customized so your theory on noise interferace may not apply to me.
My rom ID is 722525. I plan to try your parameters with Kevins software. Will let you know how it goes!
John
