datalogging boost with Crome
 

just bought CromePro, got everything hooked up fine, datalogs and autotunes perfect...except for the boost portion of the map. it will log all the way to 0.4+ then the map trace will follow the map up tp 8psi, but it wont log any values. is there something that i am missing? why would it log everything except boost, especially when the ecu is seeing it, because of the map trace going into boost.

it datalogged fine with Uber on the same car/ecu as well...

'90 hatch converted to obd1
'95 b18c1
P06 converted to P28, datalogging setup by Xenocron
P30 map, boost tool added, 450 injectors, 1.8L displacement, RTP+DataLog

What are your AFRs?

In the Tuner section of the properties you need to set the range of AFRs it will log. If you are super rich and the AFRs are richer than what you have set...it wont log any values.

thanks, Bigwig pointed that out about an hour ago on d-series.org.. got it to log fairly well. had to change the engine temp range as well since the motor doesnt run a thermostat because of heat issues. also found that Crome read the throttle position as 101% when WOT, and the log range was from 5-100%, so we were missing some there. changed it to log all the way to 150%, lol

logged pretty wel, probably not as well as im used to with Uber, but it did a good job. did several WOT runs got some good fill, and tuned it to around 11.7:1 for now. might lean it out when we hit the dyno.

thanks for the input

yeah, i set up all of my logging parameters with a very large gap so it logs everything

i had to do the same, and i think im going to widen it some more the next time i head out street tuning. thanks for the input!
