Hello all

I am trying to get my lancer ready for a turbo and I've seen that a compatible evo rom or tephra rom will do. I opted to try the evo rom first and I've made what I thought was all the necessary adjustments to get the thing to run but it doesn't, at least not very well. Specifically the idle is erratic and either too rich or lean. I've messed with the maf scaling, smoothing, injector scaling but can't seem to dial it in, even while it's warmed up and forced into open loop only. even disabled lean spool still can't get it right. Is there anyone that can point me in the right direction? Maybe I adjusted too much and I need to start from a fresh rom but I'm not sure at the moment.

Here are the roms I'm working off of for reference.

 

i dont know if your still having this issue but it looks like youre using a ROM with MIVEC idk if it would cause the idle issues but i use 94170715 tephra mod, i do remember having idle issues when i first tried this ROM but i have it all working well now
