hey guys, ive been tuning for a few years (mine and customers in sd) using the stfts for everything bar WOT. WOT was checked with a my wego wideband and adjusted if necessary via the VE table, but it was usually spot on commanded after a stft tune. ltfts i turn off. ive had an enhanced io for a while and i thought, shit, i better get with the times and use this interface for a wideband. had nothing but trouble since. i bought an lm1 because the display was flaking out on the wego occasionally and reading .1 and i couldnt get the wego to work with hpt properly (got it working now though), did a tune on my own ute which is cammed and turbod. got it spot on in open loop with the lm1. turned the st trims back on and its pulling like -8 to -12 everywhere.
after reading all that, i guess what im trying to say is, is there really anything wrong with tuning the part throttle with the narrow band 02s? and are lm1s shit?
btw i have swapped in a new set of NB 02s and checked the wot afrs with a dyno wideband and thet are ok. the dyno wideband shows 13.5-6 at part throttle.
