KR Question??

sounds like your tune is off or you have a small vac leak which is forcing the car to run lean.

That's what I am thinking. If I was you, I wouldnt go WOT until you get this addressed. If there any local tuners...see if you can get them to tune ya.

 

[iluvbst]

but my car is stock...i dont have an tunable ecu...unless the stock one is tunable...sorry for the noobness lol...i know alot about cars, but new to these...

 

[CTKGP09]

ecu=pcm for these cars (Powertrain Control Module) just for future reference

if its stock you can get it reflashed at the stealership

 

[iluvbst]

and what would that do for me? reinstall the stock tune?

 

[Bio248]

it would do nothing. if your car is stock then something is wrong. im still leaning vac leak.

ok thats what i was thinking..going to do some more test..back in a bit.

 

[CTKGP09]

right, check yourself first and be pretty sure the PCM is screwin up before you pay to have it done

 

[iluvbst]

what should the vac be at on these cars? i just did another vac test, and blocked off a suspected hose, and still the same 18 to 19in. and i just took some maf readings, and i get 5.6g/s at idle and 159g/s at wot...converted its 21 lb/min whichever is easier..is that a normal reading?

If you 18 -19* it doesnt sound like a vac leak to me. Possibly just a whack tune IMO. If it was me.... I would unplug the battery for like 30 mins... then plug it back in. This will force the PCM to relearn the fuel trims.... which could take several med-long drives.

I lol'd....

its POWERTRAIN control module.

 

[iluvbst]

^^ lol i know, i didnt bother to say anything...didnt want to sound like a dick...so this pcm has to be unplugged for 30min?? well battery i mean..

 

[matt5112]

yeah, then drive it for a while

 

[iluvbst]

can i leave it unpluged overnight? then drive it in the morning..or it has to be exactly 30mins?

 

[matt5112]

you can do the overnight thing.

Just dont forget else you'll think your car is dead haha.

 

[iluvbst]

ok heard lol, should i do any wot pass in this relearn process?

 

[matt5112]

not really.

The car doesnt learn fuel trims at WOT IIRC

 

[iluvbst]

ok and should i have unplugged the the positive or negitive terminal?..i know some cars are diffrent about that...

 

[matt5112]

either?

Depends if the car was wired with conventional or modern electricity.

i'm not kidding about that either.

 

[Bio248]

it doesnt matter, however, youre 'supposed' to disconnect the negative terminal when disconnecting batteries.

 

[iluvbst]

how the hell would i know that! lol
