hi everyone,

i have disabled egr bit on this ecu, like i do before with other model (934-277) same car,same engine. The problem occur only on highway at constant speed (no matter what speed is) the glow plug light turn on and mil light too, if i turn off engine and turn on again the idle speed are crazy, oscillating from 500rpm to 900 rpm. if i turn off engine wait 10 minutes and turn on, everything is ok just mil still on (with ODB2 the error are the glow plug dead only). This happens only with this ecu, i don't have the egr valve.

can someone check if i disabled egr correctly ?
