Greetings,
just got the red devil river connected to my gm ecm and am connecting to it with the aldldroid app. The monitoring is good, but the strangest thing happens when I connect to the red devil via blue tooth, the idle speed goes up to 1000 rpm.

when I disconnect, it goes back down to 650ish.

i have "desired idle speed" as a readout on aldldroid and it says 1000. However, when connecting to the ecm with a USB adapter to PC using winaldl, the idle speed is unaffected and "desired idle speed" reads 600.

anyone seen anything like this? Even better, know how to solve it? Make it kind of tough to use the device to verify idle speed.

system background:
gm 5.7l in. Y boat. Put a long block in this summer and decided to go from carb to EFI. Bought a kit from affordable fuel injection. It came with a salvaged ECM 16144288. The ADX file is e $A0.adx with one mod to make the "coolant temp" names different.

Any ideas will, of course, be greatly appreciated.

Regards,
david
