Hello. I'm looking for a guide that helps me to install the hardware mods required to make an evo 9 works in tephra speed density.
Thanks

 

I hate to be the one to say it, but you need to use the search button.. There are tons of threads on this subject.

 

Why don't you guys just put a link up, instead of just saying "search button" or "search for it"?

 

maybe whoever answers you doesn't know exactly where it is and instead of searching for it for you, they are kind enough to ask you to search for it yourself

 

And this why people don't go here to ask questions...... And some people are not that good at searching OR there search doesn't pick up what they need.

I have done that plenty of times and don't ask the question on this forum, so I google it.

 

Need help Guys, My evo 9 having this isseu, when i press in the clutch under boost the rpm shoot up to red line,it happining on wot, when your at 5000k or higer, my mods are exhaust manifold, o2 dump, 3"down pipe with hfc, prerrin intake, hks ssqv4 bov, any body had this issue? thank you in advance

 

And i also have 3 port grim speed boost controler

 

Why would you post this in another persons post about something completely different? He is asking about speed density and your asking about "why does my car have issues". You should be looking elsewhere.

 

He maybe wrong for posting that here, but this is exactly what I'm talking about. You guys radical someone instead of helping them.........Sorry Evo 9ssl, you probably should post this in another forum and you might, just might get help.

ronaoldo9 is AWESOME!!!!!!!

Thank you! if no one has ever said it.

 

There are many many threads on this but I hope those are helpful. I'm still on maf myself but may take a stab at speed density as I'm reading an IAT sensor is not needed for the conversion and you can use a fuel temp sensor.

 

haha I think evo9 ssl was illustrating why searches don't always come up with relevant results. Misspelling and an abundance of keywords which may or may not be relevant to the issue at hand..

 

I know this is a delayed response but I run on speed density and i HEAVILY reccomend using and IAT sensor. The owner before me blew up the engine because of it and I wouldnt have noticed either until the shop i brought it to after figured that out when retuning it

 

you cant use the fuel temp sensor itself, you can use the fuel temp sensor input to the ecm but you still need the same hardware in place you just wire it into a different spot on the pcm.
read carefully, folks.
