I’m suppose to be getting the Driftmotion piece to convert the throttle today.. and I swear if that doesn't work I’m gonna look for a JZX100 throttle body because I’m done with this e-throttle nonsense.

In the car right now, gonna make the log for u.. btw its Error Code 76 I have now.. TPS main and sub tracking error, I think its both errors I get 77 and 76, but for now I'm gonnna clear the 76 and make the log running the throttle in the when stalled mode. its giving me Max total size of 180kb but the file is 1mb.. not letting me upload

Hey, so am got the car running, still cannot figure out why I constantly getting Error a code 77: APS Main and Sub Tracking Error.. due to APS Sub open Voltage reaching 5V, and APS error high value is also at 5V, and I cannot change the error value higher than 5V. No matter what I do with the APS settings and constantly calibrating it.. it will always hit 5V and trigger the fault code. with e throttle in the ON position it cuts my throttle down to 1800rpm, but in Setup Mode I can still drive the car with the error present(and cel on) it’s the only way I could get the car tuned as well. I have tried changing everything in the ethrottle.. nothing works, error after error.. I’ve switched over main n sub analog inputs for both tps n aps, switched the aux 9/10 around, low to high on the state, just to see.. but nothing works. So everything is back in its original state which is in the altezza base map.. of course I also copied all the values for the ethrottle system over to my base map because the jzx100 base map does not use the ethrottle since their intake is “ETCS” and mine is “ETCS-I” from the JZX110/JZS171. Only thing I have different to the altezza settings is that APS Sub 100% is set to 100%. I can’t find or don’t know if there is any specific settings available online for my specific e throttle. (P gain, d gain, tps sub 100%, and those stuff) I will make a log tomorrow. Btw, the cycling of the idle was due to the idle control settings being off and when it was on, it just wasn’t catching the idle properly due to incorrect settings for the table and stuff.. so that’s been fixed.

I got the car to idle properly, it revs without any tps aps errors, but it’s weird that when I let off the pedal, it starts jumping between 1000-1300 rpm in an up n down rpm motion.. I noticed every time I let off.. the tps % is 4.1, rpm goes up n down for about 2-4sec until the tps is like 3.8 ish % then looking at the runtime value page, I see the idle control “kicks in” and idle normalizes and tps goes down to 3.5%..

I seem to be getting rpm lockout on the Idle status and Ignition idle status as soon as I touch the gas pedal. attached the log PC Datalog - 2021-02-18 7;40;20 rpm lockout.llgx

I adjusted the throttle cable, re calibrated both tps and aps.. I dont seem to be getting any more tracking errors, Ive ran the engine few times and revved with no issues, I guess its good now.. just on to the next problem.. where the car is revving but right after it goes into this up n down "phase" between 1000-1400rpm and the %fuel cut% keeps flashing red but remains at 0.. and by the looks of the afr, it seems to be cutting the fuel since it bounces between 14 n 17 afr. Here's the log maybe u can see whats happening PC Datalog - 2021-02-18 5;50;36 pm.llgx

Pedal to the floor, it still has tad bit under half an inch of travel until full but it doesn’t move back once an move it by hand.

I assume I’d have to remove my ic piping to see if the flap opens correct? It’s raining over here rn, Gonna try check that later tonight then.

I calibrated the APS just before starting the log and TPS was already calibrated couple days ago..

Sorry to bring up an old thread but how did u manage with your tune? seeing that 2 years have pass I assume u got everything fixed and running? or.. I am also having some issues with my setup.. running JZS171 in my IS300 using the AltezzaLink so our setup should be the same.. however I am on stock injectors and running Modelled Mode. Do u mind sharing your setup with me so I can compare mine?

Hi, would like to ask if anyone has a Base Map for the JZX110/JZS171 or the 2J with the ETCS-i throttle body? or.. know what might be going on: I have a very sloppy throttle and I cant figure out why.. and sometimes I get APS / TPS tracking error when I try to rev as well. Car: 01' IS300 with 1JZGTE VVTi ETCSi out of a JZS171. Completely rewired to " Plug n Play " AltezzaLink G4X ECU. Mods: GT30 Turbo is my only "big" modification, otherwise stock 1JZ, AEM 340 Fuelpump, stock injectors, FMIC.. Exh is 3" straight. Got it to calibrate both TPS and APS but it still feels sluggish and just not acting the way it suppose to and I am lost with a solution. Just got it started the other day with the JZX100 Base map with some changes to it for the input n parameters matching the Altezza basemap, as well as switching some of the obvious stuff from the JZX100 that the JZX110/JZS171 do/dont have.. E throttle for example.. (also found it strange that the JZX100 basemap in the folder came setup with 500cc injectors.. I changed that as well to stock 370cc injectors. Thanks In Advance.
