Nistune Forums

Hi Matt

It looks that there is problem with VEMS wideband at actual Nistune version. While it worked for me in older Nistune version, it WB display stuck at 10 AFR without any reaction. Communication with wideband is OK. May I kindly ask you to check this please?

Thank you

Thanks a lot for your effort Matt,I will test it and post results.

Thanks Matt!

Hi Matt,thanks for reply. However,its probably small confusion here. Point of the log that you referring to is from 3rd gear run,which is completelly ok and afr is controlable by map,inj.time rise at 6000rpm is not issue. But when you check next run at this log,its 4th gear and at about 4600rpm is p...

Hi Matt,just by the chance,did you had time to check this issue?

Hi Matt,thanks for the reply. Attached are log files of separate 4th gear run and some 3rd and 4th gears runs at one session. Related maps are in test10.bin file. There is also test8.bin where I tested radical lean out at related are,but without any influence to AFR (after 4600rpm point). Thank you ...

Hi all. I have strange issue of injector timing at s13,ka24e, ecu 42FXX with turbo and 770cc inhectors. Problem is sudden injector timing increase at more or less exactly 4600rpm. After this rpm point inj.timing doesnt follow fuel map anymore and cause very rich AFR. Main fuel map, knock fuel map an...

well, try to move tps to get idle switch close earlier to activate aac valve soon enough to avoid rpm drop...

table that I mentioned is called idle/deceleration vs RPM (TPS ON) , do not change other timing tables for off throttle rpm management.

increased timing will increase torque that will lead to engine do not dip that deep-it will compensate light flywheel. increase of the rpm will be compensated by aac then. more modern engines like sr use ign. timing change to adjust idle rpm...

try to increase ign. timing vs rpm at neutral table..

Thanks for the info Matt. May I also ask if this ECU can directly accept 0-5V AFM or use 2-7V offset and have to be hardware adjusted for 0-5V AFM types?

Thank you

Hi all

I got ECU from 200sx S13 with ka24e engine with ECU number A11-B15G11 0205 and inside of the ecu with G280AFM8 at the eprom sticker. Im not sure which address file is correct for this ecu (and for nistune board configuration)?

Thank you for your help
