Re: KA24DE-T Injector Resize TP Question

If you could play around with this table on the bench and characterize its effects, that would be very big help! It might be throttle based or RPM based, or the delta-RPM(derivative aka change in RPM) based or deltaTPS (rate of TPS change) or both. Any updates on this? Just curious if you had time ...

Re: KA24DE-T Injector Resize TP Question

Those logs look a lot better than before, but still leaning to 16:1 Okay, does that sync table take away that lean spot we are seeing? It happens significantly less, and typically now at throttle tip-in it goes pretty rich, to ~15.3 then back to 14.7 like its supposed to. At very light throttle, it...

Re: KA24DE-T Injector Resize TP Question

I may have narrowed down the map that changes this behavior.

"Sync RPM Factor" in expert view seems to change characteristics.

Re: KA24DE-T Injector Resize TP Question

Try some stuff here: Keep your fuel values the same for the last two columns, because it is fluctuating between them. Is this a turbo or non turbo setup? Appears you are using around 740CC injectors? This is a Non-Turbo KA24DE with a SR20DET T28 Turbo fitted to it (Basically NA ECU being tuned for ...

Re: KA24DE-T Injector Resize TP Question

Looking more through the logs I was surprised to find that the "Injection Time" and "Injector Duty Cycle" are not a derivative of each other (aka Injection Time and Duty Cycle slopes/graphs are often a bit different than each other). It seems like the AFR follows more closely to ...

Re: KA24DE-T Injector Resize TP Question

How do you simulate all the inputs into the ECU on the bench? Signal gen for RPM and speed, and variable 12v voltage sources for TPS MAFS and temp? The EGR map you added does make a difference as leanness is not so severe when the map is set to all 0s, however the injection time still does the step ...

Re: KA24DE-T Injector Resize TP Question

Turns out both MT and AT Feature Pack base bins exhibit this lean behavior, so at this point I dont have a BIN that DOES NOT do this, there fore I cannot narrow down the parameter. Im not sure if I can use non FP bins in Hardware that has a FP Firmware loaded, nor do I want to try this since the iss...

Mr Matt, No joy with your updated bin, still lean for the first second on the throttle then injection time spikes (See log + bin). fan_fix_matts_map_2018-05-15_0916_06.csv I was trying to see what you modified in the "Fan Control Flags" and both the old map and your new map look identical,...

Re: KA24DE-T Injector Resize TP Question

I came into possession of a manual s13 KA24DE ECU. do you think if I installed the nistune board with the auto base image into the manual ECU, the lean out would go away?
