Greg1987 Posted July 11, 2022 Report Share Posted July 11, 2022 Hello everyone. Can you guys please help me to set up my launch control on lancer evo 8? I did connect wiring and launch control is working but I have no idea how to set up those options. I am handy with the tune but this is actually first time I am setting up launch control. I don't know how much timing retard I need to set and what afr. I don't want to be harmful to the engine with to much timing retard. I am including screenshot what I did so far. Thank you so much!!

Adamw Posted July 11, 2022 Report Share Posted July 11, 2022 -20 or -30 would be a more typical ignition trim. The rest of it looks ok as a starting point. You may have to set the limiting advanced mode on if it needs a more aggressive limiter. Quote Link to comment Share on other sites More sharing options...
Greg1987 Posted July 11, 2022 Author Report Share Posted July 11, 2022 Thank you Adam. I will change ignition trim to -20 and try. Is there any specific afr that I should stay between during the launch control? I will play with advance mode also. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 11, 2022 Report Share Posted July 11, 2022 AFR is irrelevant when you have a limiter working. You cant measure AFR when there are cylinders full of oxygen (no combustion) pumping through the engine and exhaust. Quote Link to comment Share on other sites More sharing options...
Greg1987 Posted July 11, 2022 Author Report Share Posted July 11, 2022 Yes I know afr is irrevelant when I am on limiter but how I can know if I am doing it the correct way? I mean if the car is not too lean or too rich? I can see my afr is going to 10afr when I am on launch control but like you said it is not possible to measure it.

Adamw Posted July 12, 2022 Report Share Posted July 12, 2022 If the AFR is correct in the same cells when driving normally that it operates in when on the launch limiter then your AFR will be correct during launch also. Quote Link to comment Share on other sites More sharing options...
Greg1987 Posted July 13, 2022 Author Report Share Posted July 13, 2022 Thanks Adam. I did couple adjustments today and it works good. I have one problem and question. I set up speed to 15mph so launch control should not operate above this speed but it is still operates. Even if I drive 60mph and I push the clutch and rev the engine launch control is active. Where should I look to correct this? Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 13, 2022 Report Share Posted July 13, 2022 Launch speed disarming uses driven wheel speed, so most likely in >Chassis & Body >speed sources > setup you dont have a driven wheel speed source set up. castillaricardo 1 Quote Link to comment Share on other sites More sharing options...
Greg1987 Posted July 14, 2022 Author Report Share Posted July 14, 2022 Ok I checked it and I have it set up like this. If I change pull up resistor to On it is still not working. Is this set up correct or I have it wrong. thanks! Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 14, 2022 Report Share Posted July 14, 2022 Wrong setting, you should be in >speed sources >set up. And looking at "driven wheel speed source". Quote Link to comment Share on other sites More sharing options...
Greg1987 Posted July 18, 2022 Author Report Share Posted July 18, 2022 Thanks Adam. What should I set it to at driven wheel speed. I will try to play with it today or tomorrow and I will post the results. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 18, 2022 Report Share Posted July 18, 2022 Attach your map, I will take a look how your speed sensor is set up. Quote Link to comment Share on other sites More sharing options...
Greg1987 Posted July 19, 2022 Author Report Share Posted July 19, 2022 I will sent map tomorrow. Here is picture that I made earlier today. I was trying to change driven wheel speed source to left or right wheel but no luck. I think I am doing something wrong Those settings are set to NONE I think this is my problem right?
