No I don't. You can however use the same method, trymalyzer is very versatile.
P01 & p59 both have an egr pintle position pin. Even on factory vehicles that never came with an egr valve. You have to set up your adx of using tunerpro to log, for the curve of your WB. I believe there was a write up on the Moates site that was very helpful for this, and there is a lot of info for HP tuners doing the same thing. You also have to make sure you fail your MAF and are running speed density to tune your VE.
If your logging software doesn't have the ability to set it up in the log, you can still log egr pintle position voltage, or it maybe called egr position sensor voltage, the open the csv in a spreadsheet and enter the appropriate formula to get an afr error.
You also want to make sure you are running open loop with no fuel trims for this method. P01 & p59, usually you just have to max out the temp for closed loop. It's a good idea to filter data in trimalyzer for fuel trims 0 alslo though.
