    ECMlink Boostest vs map sensor

    So I have done some reading and cant find an answer. Both my boost gauge and map sensor are showing around 15-17 psi at full boost, however the boostest calculated from the mas is reading 33. Why would this be showing basically double what my actual readings are? My first guess would be boost...

    ECUflash Weird AFR change

    So finally got my cruising AFR up to around 13 and out of no where a day later they just went to 11 and it wants to stay there. My Idle and WOT did not change at all so it has me confused. Any ideas on what could change cruising AFR but not change the WOT and idle?

    EVOscan Fuel trims never show up idle

    So still tinkering with my tune to get AFR set perfect. I have seem to get idle to be near perfect it still shows a little rich after pulling up to a stop light around 12.5 then eventually comes back to around 14. However when I let the car idle for 16+ minutes my fuel trims never changed, I...

    I've been looking for the answer for hours but haven't been able to find anything on this. So I am running speed density and have already payed someone to tune the "turtle" with my BOV recirc'd to the IM. My question is, if I just vent the BOV to atmosphere now, will it mess with my tune? I...
