Hey everyone

Long time lurker, first time poster!

I have a JDM Evo 7, with Tephra 90550701. I'm interested in going MAFless, and also interested in seeing the live map, if it exists. I assume live map makes it a lot easier to tune?

Can anyone help me with the ROM and XML for these?

Can someone also post a link on how to copy a tune from MAF to speed density? I assume you copy most of the tables across, and there is a conversion for some other ones?

I have a JDM evo 7 which has a MAP sensor - do I simply replace this with an Evo 9 3 bar sensor to enable SD, along with the appropriate ROM, or do I need to get something like a GM MAP sensor?

I gather I need an IAT sensor too. Turns out my car already has one, screwed into the upper intercooler pipe, dangling there, from several owners ago. Which pins do I connect this to?

Finally, is it possible to get a closed loop AFR control? What input would I wire a wideband O2 into? And what input to I wire the MAP sensor into?

Really enjoying learning this whole new world of ECU tuning!

Thanks!

 

Looking for it also!

 

simple task,

I also have a evo 7 , similar to you guys. I used my Omni 4 bar and plugged it directly worked in the factory location and plug.

as for the iat wire that into your maf plug same wiring as any other evo 8 or 9.

and lastly for ROM , use any evo 8 sd rom, takes some technique and patience, I have tried all with success. just wanted to know know which is better for me .

when you get to that stage you can PM me and ill assist best I can
