Would it be asking to much to have Cobb add a simple feature to open the exhaust actuator at a specific, user defined set point (RPM)?

You need to open the E30 map in ATR and adjust bank 1and 2 fuel scalar to account for the additional ethanol. If you look through the ATR help file it will give you a chart to help you get started.

Once you get the fueling situated you can start adding some timing to really make use of the e85. Be cautioned though, running on straight e85 you will probably be able to advance past MBT before you start getting timing corrections.

Pro Tuned will always IMO, get you the best results. Check out COBBs website, they have a lists on who they suggest. But not sure if any pro tunner will go with E85 without any specific modifications to the fuel system. Just don't know. I am very happy with E50, just saying.

Reset to the default data logging list on the AP and get a log from a 3rd gear pull. Also, give this a read through before logging http://www.e90post.com/forums/showthread.php?t=696472

You can, but I would recommend against it. It appears that the DPfix can cause some unusual issues with fuel trims. I would recommend only installing for inspections and then remove it and reset the ecu.

Thanks! How do you reset the ECU via COBB?

Does COBB have a CANclear like function where it suppresses the CEL while being catless?

yes all the stage 2 maps have a Canclear like function. and if you go into ATR you can turn it on for other maps also.

All stage 2 maps disable the cat efficiency checks, meaning they won't trigger a cat ineffeciency CEL. However, unlike CANclear, if you have another code triggered it will not immediately clear it. This is MUCH better approach.

To reset the ECU just click on the "Diagnostics" menu option on the AP then you'll see the Reset ECU option.
