Anyone else besides me have the gsc s1 cams for there evo IX's? We'll i installed them yesterday and they've been running a little funny. Whenever i hit Mivec (5000 RPM) and and put the car in neutal the car will start getting lopey around 2200 Rpm's and it'll stay there. I heard that on the IX's they have a code for the car running to rich and it will throw a code and what is happening to me will happen. I was just wondering how everyone elses GSC S1 cams are running. I do have a tune for the cams but it is only a mail-in.

 

Bump for any advice/help

 

Maybe get a real tune for the cams?

 

I haven't had any issues with my S1 cams and they have been in the car over 3 months .

Also you say when you hit MIVEC at 5k , I'm not following .

 

yeah, mivec is NOT similar to vtec....

 

you can do a custom tune online....


you need to get a wideband and mitsulogger/evoscan

do a couple logs and send them to jestr.

 

Do you guys have the cams in your car? How does it run?

How is your map? Are you running rich or lean? Hows the timing? Advanced?

 

Mivec starts around 2000 rpms...its a smooth delivery of power as mivec kicks in the lower rpms to also enhance torque down low as well as to spool the turbo quicker. There is no BANG/LOUD NOISE or significant power delivery other than boost. A tune for the cams would be a good idea.

 

I do have a tune, a mail-in from jestr. I'm really confused....I don't even know where to start looking. Right now i'm just thinking that the tune was a little off. Jestr is going to send me another tune, so we'll see what happens then. The mail-in he sent me had a little more timing and was running a little bit more richer.

When i start the car up the idle is fine. Its when i hit full boost and it starts acting all funny. When i put it in neutral it will start been lopey at 1k jumping to 1300 and coming back down, then a little later it will jump to 2200 and start being lopely around there. When it gets to 2200 it doesn't come back down unless i turn the car off for like 10mins and restart it.

 

Bump for more opinions

 

Get a custom tune.

 

When i read that, I almost coughed chewed twizzler bits thru my nose. Come on Bro.

 

GO to a tuner and have them tune it. Do NOT mail your ecu off for an off the shelf map. This will probably straighten things out.

 

Wow.. Have a local shop look at the tune? Could be an option
