firmware update idle isues

Recommended Posts

hello guys,

i have a PnP G4+ on my Toyota MR2 with ethrottle.

i have just upgraded the firmware from 5.1.0 to 5.6.7

and when i start the engine it doesnt idle steady,it fluctuates and i can see the TPmain going up and down from 3% - 8% .

i did a data logging but i cant figure out whats going on.

BTW, i downgraded back to 5.1.0 to check and engine idles normal.

any suggestions??

Drop your idle proportional down to 1.0 and your anti stall gain down to about 2.5.  Let us know if that settles it.

Are you maybe using an extension cable on the USB?  Store issues usually mean you have a comms problem.
