    I’ve recently got ahold of access-tuner and have been tinkering around with a tune for quite some time. I’ve noticed that it takes my MS6 about 25 minutes to get to operating temp. I was wondering if I screwed anything up in the tune. Does the “bat vs ect ignition” tables affect warm up? I’ve messed with the high load/high rpm ignition and fueling but I haven’t messed with the stuff down low. I know on my mega squirt on my Miata there’s warmup enrich settings that will change all that. Any help will be appreciated. It’s just driving my nuts having to drive my car luke warm or wait 25minutes.

    Check your thermostat for being stuck open. How fast your car warms up is based on mechanical factors not tune related. However if you drop your cold start idle down it will take it a little longer but not that much. You either have a faulty ect sensor but more likely a stuck open thermostat

    That’s what i was betting on too. I was just hoping it was something I messed with in the tune. I haven’t messed with the cold idle.
    The thermostats are a fun job on these cars.
