bmx045 Posted April 10, 2012 Share Posted April 10, 2012 do you have an intake? doesnt show any knock, however Link to comment Share on other sites More sharing options...
iNVAR Posted April 10, 2012 Author Share Posted April 10, 2012 You have a small leak somewhere or you have an intake. You don't have knock, but you most likely have a leak, or you have an intake. Where do you have LV installed? That's where the JPG files should be. Link to comment Share on other sites More sharing options...
timbo7 Posted April 10, 2012 Share Posted April 10, 2012 I have an AVO panel filter. Thats it. Assuming everything else is normal then? Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted April 10, 2012 Mega Users Share Posted April 10, 2012 Could be the filter. That's about what my LV's looked like with a afe panel filter. My LV's never looked that clean with it though. Link to comment Share on other sites More sharing options...

iNVAR Posted April 10, 2012 Author Share Posted April 10, 2012 Could just be the panel filter, but I used to have that too and never got positive trims like that. I would check for a small intake/vacuum leak somewhere after the MAF sensor too. Your ECU is adding fuel right now to compensate for the added air. And at 13% at the idle trim, you are on the upper end and near the limit of15%. Link to comment Share on other sites More sharing options...

And at 13% at the idle trim, you are on the upper end and near the limit of15%. I did have my snorkel thing (below the filter) out until a few days ago. I drove maybe 10 miles since then. Would this make for the high number? If not ill have to double check the intake area. Link to comment Share on other sites More sharing options...
iNVAR Posted April 11, 2012 Author Share Posted April 11, 2012 No, the snorkel shouldn't do that either. You are looking for a POST MAF leak. Vacuum hoses, throttle hoses, anything after the MAF sensor. Link to comment Share on other sites More sharing options...

If I find a look connection or something will the number change immediately or do I need to drive a little? Link to comment Share on other sites More sharing options...
iNVAR Posted April 11, 2012 Author Share Posted April 11, 2012 takes a while to readjust. pretty long while.... the one that'll change the quickest is the idle one (A) because the fluctuates a lot... you can actually see it change before your eyes when you're in RR. the others take much longer. see if you find something first.

So I looked around for a loose hose and couldnt find anything. I had my intake apart since I did the plugs a few thousand miles ago. I took it apart again and made sure it was sealed and put together right incase I missed something. Drove about 25 miles today. The first number is alittle lower now. Would it slowly go down if I drive more or what else should I check? Also saw one of the other numbers is now reading something instead of 0.00. Is this a problem? Should I figure out the a/f ratio stuff before buying tune? Thanks for the help. Link to comment Share on other sites More sharing options...
fahr_side Posted April 13, 2012 Share Posted April 13, 2012 You still look to have a leak somewhere. There's no point in tuning a sick car and a reputable tuner will decline to do so. The small FLKC value could be many things. I'd work on your fueling problems first.

timbo7 Posted April 13, 2012 Share Posted April 13, 2012 New LV. I cleaned the MAF sensor. The first number seems alot better now. I unplugged the battery after I cleaned it and drove about 10 miles. Im going to do another LV after the next time I drive too just to make sure its okay. Would the number go back up right away if it wasnt a dirty MAF? I double checked all the hoses again and couldnt find any loose ones or ones that popped off. Also, what is that IAM in the top right? It was 1 now its .5. Just curious.

bmx045 Posted April 13, 2012 Share Posted April 13, 2012 sometimes it takes a while after a reset to get back to 1. if it got to 1 after your reset and now it's .5 thats bad. mean you have a lot of knock. Link to comment Share on other sites More sharing options...
fahr_side Posted April 14, 2012 Share Posted April 14, 2012 Also, what is that IAM in the top right? It was 1 now its .5. Just curious. As stock the IAM will start out at 0.500 or some other value <1.000 after a reset, and a lot of tuners will leave the customer with a final map like this too. You drive for a while in all load ranges and when the ECU sees no knock it will increment back to 1.000 soon enough. Just keep an eye on it to be this happens, and where the fuel trims go.

Yea I'm going to check it again after a few more drives. Other than the iam number does it look okay? Link to comment Share on other sites More sharing options...

It looks better, but you probably have to do a few more miles to get the trims settled down. You still have positive trims, and what you want is negative numbers. So, better yes... good? Not really.

timbo7 Posted April 18, 2012 Share Posted April 18, 2012 So I checked about 3 more times and still couldn't find a loose hose. The one hose to the right of the intercooler had a bend on the bottom so I fixed that but it didn't change. Is there anything else to check? Would putting in a regular fram filter help?

Mega Users seabass07 Posted April 18, 2012 Mega Users Share Posted April 18, 2012 I'd switch to a paper filter. My fuel trims were off by around that much with a dry afe filter. I had pretty consistent high load knock with it. Link to comment Share on other sites More sharing options...

Mega Users paintpollz Posted June 6, 2012 Mega Users Share Posted June 6, 2012 after new inlet installation. made sure all the lines are buttoned up nicely. still looks not so great "Remember Danny - Two wrongs don't make a right but three rights make a left."

Mega Users seabass07 Posted June 6, 2012 Mega Users Share Posted June 6, 2012 You need more time. There's no knock on there, but iam is low. I'm guessing this is right after a flash? Fuel trims are probably still learning. Link to comment Share on other sites More sharing options...
bmx045 Posted June 6, 2012 Share Posted June 6, 2012 if you romp on it right after a flash, the ecu uses rough correction and drops the iam. Ginger, reset ecu, drive it easy for a few miles, then do a full pull. you could do a log as well for good measure. Better for me to look at too Link to comment Share on other sites More sharing options...
