  1. loading a start file for my 1uz cressida

    in G4+

    Posted

    So I went through all the paperwork that the auto elec wired everything to and made sure all the auxiliary and ai ao and di where in the right spot. I was missing a few things. I set them all up. One was the ecu power. Now when I turn the key off the ecu relay ticks constantly. How do I fix that. I tried messing with the ecu power on time but did nothing. Any ideas.

    here is the file for the base tune ive been setting up if that helps

    yes i have read that hence why i was going through all the map and tps calibrations. i was more thinking of anything else he may have thought like when he found the different trigger types as he mentioned above.

    other than that i was ready to try and turn it over for the first time but seems the battery is a bit flat after today so it didn't even want to give me the satisfaction of turning over let alone starting. 

    thanks for the help tho

    in regards to the map sensor was just confirming that it will start with out a AFM since it no longer has one so long as i have it configured witch i just did then.

    ill click that spanner and change the 234 to 4 now thanks for the help 

    ok the 234 has been changed to 4. i tried that before but i must have clicked done without hitting enter so thanks.

    anything else i need to change before trying to start?

    i have also stored to the ecu 

     

    my TPS is only reaching 84% how do i calibrate that

    dont worry about the TPS that is now at 100%

    awesome info thank you. ill update that to the base map and do another store to the ecu.

    just to confirm i am right in selecting the 4 bar map sensor before it has been configured?

     

    ive manually set the triggers to what you have shown me but the calibrate will not let me change the trigger offset to 4. its locked in at 234. is this something i must change also?

    yes it gave me a reinstall option and seems to have worked. i should be ok to load this base now yeah?

    thanks for your help so far

    i stored the base map into the ecu also ill have a chat to a tuner and see if its ok to go for a start. i would like to disable the fuel so the engine primes and the timing is correct first before i go for a start tho

    IT was online before i did the update and the wiring is all done professionally even have a list of what goes where so dont think its a wiring problem . how can i do a update when 1 it says it has the latest firmware and 2 i cant find the ecu. it wont connect

    i did disconnect the battery to see if that fixes it but to no avail. and downloaded a second pclink in a different spot on the laptop but i dont want to wipe the whole pc link incase i loose my backup file. witch at this stage still can not use

    thanks for the reply

    ok i unlocked my ecu that was all good. after reading i went to do the firmware update also. ecu was connected and everything looked good. a message popped up to cycle power and i did then it said an error accrued. and now the ecu is in boot mode and i can not connect to the ecu, how can i fix the firmware if i can not connect to the ecu.

    just want to load my start file and this happened

    first off hi Rossco here.

    I have building my 1uz-fe cressida for years now and its finally ready to install a start file into the ecu...... yay for me

    i noticed there is a 1uzfe vvti start file in the pclink software

    i dont have a vvti model but assume the fuel maps would be the same?

    its a 1991 1uzfe, AFM has been replaced with a 4 bar map sensor, injectors have been upgraded to 7mge items. ethanol sensor and dual innovate wide-bands installed also and dizzys replaced with a COP setup. also added a IAT sensor and Water temp sensor 

    im no tuner but fairly savvy on PC so want to load a run file myself and after looking through the base map i see that it has direct spark selected and injection is also sequential witch is how its been wired up (professionally wired RIP my bank acc) 

    i changed the closed loop lambda to auto wide-band and turned off the vvti function. selected the 4 bar MAP and saved the file to a usb stick.

    am i able to load that file and safely start the car? i will get it tuned just need it to run been to long to not here it since its here in my garage.

    any help would be great and before you ask no its not boosted as of yet just a standard engine with this ECU and wiring setup running a r154 manual gearbox.

    look forward to a replay regards Rossco
