- ive been street tuning my b16 turbo for the last 2 weeks, everything normal ive nvr had issues with this unit for well over a year, it worked great on my b18a turbo and d16y8 turbo. i got it from phearable with replaced capacitors. i do some pulls, pull over to make some adjustments (smanager windows 10 laptop), upload the cal and the software crashes during upload (not responding), restart smanger, reopen the calibration, looks good, wont data log, lightning bolt wont light up, shut the car off let it sit for a minute usb unpluged. restart car, plug in usb, lightning bolts lights up like normal, data logs like normal, upload the calibration (serveral times to be sure), appears to take the calibration. now im getting lean on part throttle and a rev limit at 2500 rpm, almost like the launch control is activating but its disabled and in the data log its saying rev limit + ignition cut on, launch control launch retard not on, no CEL. i was able to limp the car home at 1500rpm with good afrs. ive been messin with hondata s300 v2 and v3 for 4 years now and ive nvr had any issues, no idea whats going on so i came here

just to update everyone if someone has a similar issue, i let the car sit with the battery unplugged, triple checked my calibration file to make sure nothing fishy was going on, hooked battery back up, ignition to stand by, upload cal, turned car on and its been fine, boostin to 8500 again. the smanager crashing during cal upload musta just fucked with the s300 for a bit.

Did you ever figure out the issue?

I know sometimes after doing a pull in my Accord I will pull over to make some adjustments on Smanager then, the sensors' numbers on the screen will freeze & will not follow what the car is doing even if I am "recording/live". This happens after I have turned the car off then back on after about two minutes of adjustments.

I wonder if we have a similar problem.
