dingdongdrift Posted August 9, 2023 Report Share Posted August 9, 2023 I have a question that i have not found an answer to on the forums after some quick searching. I have a LINK MonsoonX on my 1uz drift car. I have a pop/flame tune and also a regular tune for cruising around town. I would like to be able to switch between the 2 with my CAN Keypad, is that possible somehow? my main question is probably the CAN programming. I have a digital dash working through CAN and realdash, but i have not set up the keypad to communicate with the ECU, it only communicates with my PMU16 PDM. Edit: once it's communicating, i have no clue how to do digital switches, any help with that would be awesome as well. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted August 9, 2023 Report Share Posted August 9, 2023 What do you change between your 2 maps to achieve pop and flames? You need to get all the tables in one file to switch between tables and not between files Quote Link to comment Share on other sites More sharing options...
dingdongdrift Posted August 9, 2023 Author Report Share Posted August 9, 2023 fuel cut overrun is turned off and the fuel and ignition tables are both different in the high vacuum/no load areas. i set up the CAN Keypad in LINK Software and enabled CAN DI but i can't seem to get anything to show up in runtime values or anywhere really when pressing the switch on the keypad. The LINK finds the keypad in the CAN Devices tab though. Quote Link to comment Share on other sites More sharing options...

LEDs on it are controlled, if you have it setup as a keypad in the ECU then the ECU will try and control the LEDs which will clash with the PMU if it is also trying to control the LEDs. Also if you are using any form of latching there is the risk that the latching will get out of sync between the two. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 10, 2023 Report Share Posted August 10, 2023 To give a bit more info, the keypad should not be set up in the ecu, all its logic should be handled by the PMU, for the "map switch" you just send the button status from the PMU to the ECU. If you attach your maps I can get the basics set up for you. Im not sure if I will be able to get the ORFC to disable via CAN but will have a look when you share your map, it may be possible to override it with a dummy antilag setup.

DerekAE86 Posted August 10, 2023 Report Share Posted August 10, 2023 Watching this with curiosity - it seems easy enough to swap between dual fuel/ign tables. But is it possible to turn over-run fuel cut on and off via a digital or can input? And is it possible to 'latch' the active table within software between power cycles? So if the 'race' tune was table1 and the 'street' tune table2, if you turn the car off while on table2, it will start up on table2 again?

dx4picco Posted August 10, 2023 Report Share Posted August 10, 2023 Like Adam wrote, if ALS is active then over run fuel cut is disabled. So making ALS activate but do "nothing" Will be like disabling ORFC Quote Link to comment Share on other sites More sharing options...

You can set a default power-up state of the button in the pmu but not store the last used state. Quote Link to comment Share on other sites More sharing options...
