ThatSupraGuy Posted January 2, 2020 Report Share Posted January 2, 2020 Hi there. Wondering if anyone has a base map for 2jzge+t in my jza80 just to get it started to get to tuner. Running standard injectors, standard pump and aftermarket reg. Still running dizzy setup too. ECU is supralink pnp. Thanks in advance Quote Link to comment Share on other sites More sharing options...
ThatSupraGuy Posted January 4, 2020 Author Report Share Posted January 4, 2020 *Update: Have managed to get it started. Will rev but will die if I dont catch it with the throttle when coming back down to idle rpm. Is this just a tune issue or idle control? Thanks.

Probably a bit of both, have you followed all the steps in the manual - checked all sensors are reading correct, calibrated MAP & TPS, set base timing, adjusted master fuel, etc?

ThatSupraGuy Posted January 4, 2020 Author Report Share Posted January 4, 2020 Yup I've calibrated TPS and MAP. Adjusted master fuel, not too sure how to set base timing, only adjusted it at dizzy with timing light. Quote Link to comment Share on other sites More sharing options...

You need to have the “set base timing “ screen open when you do that so that the timing is locked to a known value while you check/adjust it.

ThatSupraGuy Posted February 6, 2020 Author Report Share Posted February 6, 2020 So I set all the base timing but still cant get it to idle so not really sure how to go about it. Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 7, 2020 Report Share Posted February 7, 2020 Do a short log of it running and attach that and your map here. https://www.youtube.com/watch?v=_P1LRANeO4A Quote Link to comment Share on other sites More sharing options...

Adamw Posted February 8, 2020 Report Share Posted February 8, 2020 Ok, I see a few things wrong. Inj 8 which was ECU hold power has been turned off - this is needed so that the ecu can stay alive for a few seconds after shut down so that the idle valve can reset to its home position. Also your hold power keep alive time was set to zero. Without these the idle valve would have always been in an unknown position - most likely fully closed. Your idle base position table was "back to front" (bigger numbers when cold instead of smaller), for a stepper motor this table represents "steps from fully open" so smaller number means more air. I have fixed these mistakes up in the map attached below. Load it in, do a store - then power off for say 10secs then back on and start. See if it is any closer to working. If it still doesnt idle you can highlight the whole idle base position table and hit say "-50" to make the whole table smaller which should give you more air/higher idle. A couple of other things that dont look right and need to be considered: Your dwell table is set to "duty cycle mode", this is pretty unusual and may be difficult to get right (typically only used for CDI systems and odd dwell controlled small modules). I would probably change it back to ms mode unless this was done for a specific reason. Your Lambda is showing about 0.55 which seems wrong - I dont even think the X series can measure that low. So I suspect you have a calibration problem here. This means your fuel mixture is not where you beleive it to be and may be contributing to your idle problem. 1943688588_2JZGET Fixed idle settings.pclr Quote Link to comment Share on other sites More sharing options...
ThatSupraGuy Posted February 8, 2020 Author Report Share Posted February 8, 2020 you my friend are an absolute legend. its idling sweet. have adjusted the base idle so its idling at 750 ish rpm and changed dwell from duty to ms. and also adjusted master fuel which seems to have brought the lambda up too. just need to get it tuned properly now. thanks heaps for your help. 2jz+t first test drive.llg 2jzge+t base map.pclr woz1999 1 Quote Link to comment Share on other sites More sharing options...
